Due to the large power supply load gap, many industrial zones in Guangdong Province stopped production in turn and started off-peak electricity consumption to cope with the power supply problem.

According to "Zhongshan Daily" reported on May 26th, due to the acceleration of economic recovery and the continuous high temperature, the demand for electricity in Guangdong Province has been rising, and some areas in Guangdong have started the peak-shift electricity consumption mode. Some enterprises in Zhongshan have responded to the difficulties by purchasing generators and adjusting working hours.

"Zhongshan Daily" quoted a staff member of Chaozhou Power Supply Bureau as saying that the current load growth in some areas far exceeds expectations, and the power supply is tight or even insufficient at peak hours. If the power is overloaded, "the line is prone to collapse, causing a large-scale load trip and power outage, so some users need to cooperate with the peak shift to control power consumption".

Staggered peak power consumption refers to a series of measures to guide users to adjust their production arrangements in order to solve the short-term imbalance of power consumption load, and transfer part of the load in the peak period of power consumption to the low period of power consumption, so as to reduce the load difference between peak and valley.

According to the interface news, the peak electricity consumption has been in Guangdong Province for two weeks. By the end of May, the power rationing situation continued to increase, the scope was expanded and the time was lengthened. In some places, factories had been open for three times and stopped for four times, which had a negative impact on the order fulfillment of factories, and workers could only be arranged to work in shifts in the morning and evening on the day when the power supply could be normal.

On May 14th, a kitchen equipment manufacturer in Panyu District, Guangzhou disclosed a notice of off-peak electricity utilization, which showed that on May 16th, at the request of the superior power supply bureau, off-peak electricity utilization will be implemented every Saturday and work normally on Sundays, and the off-peak electricity utilization cycle is expected to last for three months.

Subsequently, Foshan, Shantou, Dongguan, Huizhou, Zhuhai, Zhongshan, Chaozhou and other places began to implement off-peak electricity consumption.

On May 18th, Shantou City, Guangdong Province began to implement the "five stops and two stops" orderly power consumption. Industrial users need to take two days off every Tuesday from the benchmark date, and stop producing electricity at 9-12: 00, 14-17: 00 and 18-21: 00 during the peak hours of power consumption, and only keep the security and heat preservation load.

On May 19th, Humen Power Supply Bureau of Guangdong Power Grid issued a document saying that the customers of industrial transformer in the whole town need to implement the orderly power consumption plan from May to December, and impose an additional penalty of 48 hours of power outage on enterprises that unconsciously implement orderly power consumption.

On May 24th, Guzhen Town, Zhongshan City, Guangdong Province began to implement the "five stops and two stops" scheme. According to the notice issued by Guan Wei of the Party and Mass Service Center in Gusan Village, Guzhen Town, from now on, the peak-to-peak power outage will be on Sunday every week, and the power transmission will be stopped from 7: 00 am to 23:00 am every Sunday, and the elevator may not be used.

In addition, some industrial users can’t use electricity for production and work, and can’t turn on high-power electrical appliances, such as air conditioners, even if they have electricity during off-peak electricity consumption.

Since 2014, China’s economy has entered a new normal, the growth rate of electricity demand has slowed down, and the phenomenon of power rationing has rarely occurred. Even if it appears, it is mostly in the peak period of electricity consumption in July and August. Why did it appear in May earlier this year?

Ceng Ming, director of the Energy Internet Research Center of North China Electric Power University, told Interface News that there are four deep-seated reasons.

The first reason is that the electricity consumption plan arrangement is not accurate, which leads to the deviation of electricity demand arrangement on the power supply side; The second reason is that climate factors have a great influence on the demand for electricity. The high temperature weather in Guangdong has led to a significant increase in peak and valley load compared with the past. "Lack of electricity is the lack of peak load."

The third reason is that, due to the great compression of coal-fired power in recent years, the multi-energy complementarity between renewable energy and traditional energy is uncoordinated, which leads to power shortage. The fourth reason is that most of Guangdong’s electricity depends on external calls, and this year’s external calls may deviate from the original plan.

According to the news of Guangdong Electric Power Trading Center, according to the historical data of the 13th Five-Year Plan, May is in the alternate period of dry season and flood season, and the power generation capacity of the main clean energy hydropower is limited, and the maintenance of superimposed units and engineering power outages are relatively concentrated, which is actually the month with the smallest supply margin for the whole year.

From June to September, it entered the summer peak period, and the system load reached the highest value of the year. However, hydropower also entered the annual peak period, and the bidding space of market units was reduced.

But this year, Guangdong Province entered the summer ahead of schedule. The Guangdong Energy Bureau reported on May 21st that since May, the high temperature in Guangdong Province has been continuously high, with a temperature of 35℃, which is 4℃ higher than that in the same period last year, resulting in the rising demand for electricity, which has exceeded the highest load last year.

At the same time, the economic recovery is accelerating, especially the demand for electricity in the secondary and tertiary industries is strong. From January to April, the electricity consumption in the province increased by 32.2% and 40.2% respectively.

On May 10th, the Plan for Orderly Electricity Use in Guangzhou in 2021 approved by Guangzhou Bureau of Industry and Information Technology has shown that the overall power supply in Guangdong Province is expected to be tight in 2021.

Among them, the situation of power supply and demand in the province is severe during the alternation of dry season and summer peak period, and there is a big risk of power shortage. Affected by this, the power supply in Guangzhou power grid may be tight or even short at that time.

According to the research data of Guotai Junan Securities, as of 2018, the proportion of calls from outside Guangdong also exceeded 30%. Among them, Yunnan hydropower is a major power source.

However, in May this year, Yunnan, due to reasons such as not entering the flood season, had a gap in its own power, which led to the inability of western power to increase its power transmission during the tight power supply in Guangdong.

A pre-notice of emergency peak shifting preparation issued by Yunnan Power Grid on May 10th shows that the main reservoirs in Yunnan are seriously overdrawn, the coal storage in thermal power continues to decline, and the power generation is seriously less than expected. There is a power gap of about 700,000 kilowatts at the peak of electricity consumption that day.

The wet and dry seasons are distinct in most parts of Yunnan, with the dry season from November to April of the following year and the rainy season starting around May. According to the China Meteorological Bureau, the southern region entered the flood season late this year, and there was less precipitation in Yunnan in May. Recently, Lijiang City, Yuxi City and other places in Yunnan Province have issued orange warnings for drought.

Interface News contacted the relevant staff of China Southern Power Grid Co., Ltd. (hereinafter referred to as China Southern Power Grid) for matters such as power shortage and off-peak power consumption in Guangdong, but the person did not give a direct response.

Founded in 2002, China Southern Power Grid is responsible for power supply and service in Guangdong, Guangxi, Yunnan, Guizhou and Hainan provinces.

　　At the 15th press conference of the sinking incident of the "Oriental Star" passenger ship held on the afternoon of June 13th, Min Jianxiong, inspector and chief forensic doctor of the Material Evidence Identification Center of the Ministry of Public Security, said that as of 21: 30 on the 12th, the identities of 442 victims were confirmed by DNA identification and comparison.

　　After the sinking of the East Ship passenger ship, in order to determine the identity of the victims at the first time, technicians from the public security organs of the Ministry of Public Security, Hubei Province, Jingzhou City and Jianli County quickly assembled to set up a special working group. The Ministry of Public Security sent nine experts to organize and guide on the spot. The Criminal Investigation Corps of the Public Security Department of our province mobilized more than 150 professionals in forensic medicine, DNA, photography and trace in Wuhan, Jingzhou, Yichang, Xiantao, Tianmen and Qianjiang to carry out body source identification in shifts 24 hours a day; Hunan, Shanghai and other places also actively participated.

　　After 11 days of around-the-clock efforts by nearly 200 forensic doctors and DNA experts from all over the country, all the DNA information of 442 victims was compared, and the public security department will issue identification documents accordingly to help the victims find their relatives.

　　Forensic doctors who are used to life and death are sad from it.

　　5 th, funeral hall. In the face of the remains of the victims, Dai Jianyu, a forensic doctor of Jiang ‘an Branch of Wuhan Public Security Bureau, came from it. As a forensic doctor, he has long been used to life and death, but in the face of a huge disaster, his chest seems to be blocked.

　　After the shipwreck, Dai Jianyu was transferred to Jianli. Over time, many of the bodies of the victims that were salvaged were unrecognizable. In order to retrieve their identities, forensic doctors must be organized to extract DNA biological samples from the remains and their families as soon as possible, and the genetic relationship can be determined by comparing the genetic information contained in DNA.

　　The air was filled with peculiar smell, which penetrated into the nostrils of forensic doctors through protective masks. The staff is a group of four people, taking pictures and recording, and everything is in an orderly way.

　　A body was brought in, an old woman. After days of high temperature and river immersion, wet clothes clung to her. Ruan Haigen, who has been engaged in forensic work for 23 years, found that the old man still had a dark pocket sewn in his clothes, which contained 2,000 yuan in cash. "This should be her travel expenses along the way. The old man hid it close to his body, but there was no chance to spend it again. It was so sad."

　　The forensic doctor will classify and check the relics of the victims, register them one by one, and return them to their families after their identities are confirmed.

　　After a batch of remains were disposed of, Dai Jianyu was all sweaty. Tearing open the collar of the isolation suit, he flopped down in the corner and took a breath. The hotels in Jianli County are already full. Forensic doctors live in Zhuhe Town, 30 kilometers away. They can’t go back to take a shower and change clothes until 2 am, take a break and drive to the funeral home at 6 o’clock.

　　"Try your best to find the identity for every body, so that every victim can go home smoothly. This is our greatest wish. " Ruan Haigen said.

　　Minimize sampling damage

　　Usually, blood, nails, etc. are all DNA biological samples that can be extracted, but the particularity of the shipwreck makes it more difficult for forensic doctors to extract the samples. The "Oriental Star" passenger ship sank on June 1, and after the hull righted out of the water on the 5 th, a large number of remains were salvaged ashore. These remains were soaked in the river for 4 days, and the temperature in Jianli was high in early summer, and the remains appeared "giant view".

　　According to the forensic doctor, after death, the corrupt bacteria parasitic in the human body grow and multiply crazily due to the loss of the control of the human immune system. These amazing numbers of corrupt bacteria can produce a large number of dirty green corrupt gases, and the human body expands like an inflatable humanoid balloon, which is called the "giant view".

　　In this case, blood can no longer be used as a qualified biological sample, and the success rate of DNA sampling of nails can not be guaranteed. The safest way is to extract the costal cartilage from the remains.

　　Usually, costal cartilage can be extracted at a depth of 2 cm in the skin. Because of the serious phenomenon of "giant view", it needs to be extracted at a depth of 7 cm. At the same time, we should also consider the mood of the families of the victims and minimize the damage to the remains.

　　Wu Hongyan, forensic doctor of the Water Branch of Wuhan Public Security Bureau; Wan Hengyuan, forensic doctor of Donghu Branch. The two have rich experience in dealing with drowning remains. The two of them demonstrated to other forensic doctors how to complete the task of extracting materials with the smallest wound and the fastest speed. "Look at each other, and no one wants the remains of their loved ones to suffer again." This is the common aspiration of all.

　　In order to provide an auxiliary reference for the results of DNA comparison, this time, the general methods and norms of Interpol were adopted. After each body was disinfected and numbered, a personal identification form was established in strict accordance with the process of taking photos, registering clothes and personal belongings.

　　Some samples were reviewed more than 3 times.

　　With the guidance and assistance of experts from the Ministry of Public Security, the DNA Laboratory of the Criminal Investigation Bureau of Wuhan Public Security Bureau undertakes the DNA testing, data comparison and kinship determination of the remains and relatives of most victims. Since the 5th, DNA biological samples have been sent to Wuhan.

　　Zhu Chuanhong, a doctor of forensic medicine and an expert in DNA identification, said that after some biological samples were sent, due to the serious corruption of the remains themselves, DNA samples contained inhibitors, which affected the typing test results. "We can’t fully obtain accurate DNA test results by using a fully automatic operating platform, and we must combine semi-manual and manual methods." In order to ensure the accuracy of each test result, the staff tested each sample twice in three ways. After the preliminary conclusion comes out, it will be reviewed and reviewed continuously, and some of them will be reviewed more than three times.

　　After the results of DNA typing are determined, chromosome comparison is the key step to determine the genetic relationship. Fang Hui, an expert in DNA identification, said that when determining the genetic relationship, if the father, mother and son have complete DNA information, it is the best choice to make a "triplet" comparison. If only the single parent and autosomal DNA are compared, the probability of a comparison error is about one in 600,000. "When there is only single parent DNA information, if it is a father and son, we will add Y chromosome DNA identification. If it is a mother and daughter, we will add mitochondrial DNA identification to be as accurate as possible." As long as conditions permit, technicians will also extract the items in toothbrushes, sheets and pillows used by the victims during their lifetime for DNA sampling, identification and comparison.

　　Zhu Chuanhong said that the comparison of DNA involved in the case is often "one-to-many", and it is only necessary to compare the extracted DNA with the information in the database. The DNA comparison of this accident is a "many-to-many" "blind ratio", which is not only large in quantity, but also related to some victims themselves. In order to improve efficiency and accuracy, after receiving the task, they immediately sought technical support and designed a set of software for comparison. "This is a special task that has received the most samples since the establishment of the laboratory, and it is very difficult and demanding. It is both moral and responsibility to help each victim find his relatives." Zhu Chuanhong said.

　　Team strength to complete arduous tasks

　　Time is tight, it is difficult and the task is heavy. Min Jianxiong also said that this DNA comparison identification work is the most arduous task in his career.

　　"In this mission, the strength of the team is extraordinary." Fang Hui, one of the heads of the DNA laboratory of Wuhan Criminal Investigation Bureau, said with emotion. Of the 13 policemen in the laboratory, 10 are women, and 8 of them are "post-80s". The arduous task of DNA identification and comparison is to have a group of post-80s women soldiers as the main force.

　　Hu Xiaoxing, 29, has been engaged in DNA identification for four years. Like many girls in Wuhan, she also loves food, board games and shopping. But when the task suddenly comes, her "fighting power" is no less than that of young men.

　　Since 5th, Hu Xiaoxing and his colleagues have been in the laboratory for several days, and they can only sleep in their chairs for three or four hours every day. "After the misfortune happened, many people expressed their condolences on the Internet. I can use my major to help the families in distress, which feels very worthwhile. " When extracting DNA samples from biological samples, a small nail made Hu Xiaoxing almost cry. "It’s the three-year-old girl’s. It’s really pitiful."

　　Xu Fanye was sent to Indonesia to help crack down on telecom fraud and returned to work as soon as he returned home. Guo Ji was seconded to the Tongxin Police Station in Donghu Development Zone. I heard that his comrades worked overtime all night and sent snacks specially. "No one is complaining. Everyone wants to do their best to complete the task and help the victims find their loved ones." Hu Xiaoxing said.

　　For more than 20 years, Fang Hui has never heard of any laboratory in China that has accurately completed such a large number of DNA identification and comparison work in such a short period of time. "I hope that our efforts can comfort the living and let the deceased be buried as soon as possible. Get rest in peace." (KaRen Yang Luo Xuwen Yang Huai Liu Wang Xin Hong Xu)

　　Interviewed experts: Dr. Wei Zhengzheng, Research Center for Environment and Economic Policy, Ministry of Environmental Protection; Special correspondent of this newspaper, Fang Ji.

　　Article 21 of China Citizens’ Environmental and Health Literacy (Trial): Keep the environment clean and reduce the occurrence of diseases.

　　In recent years, with the rapid economic development in China, the environmental quality has been deteriorating, and the impact of environmental pollution on human health has become increasingly obvious. The health risks and harms caused by the environment have also become one of the most concerned public topics of the country, society and the public.

　　Environmental factors have caused about 12.6 million deaths worldwide.

　　In 2016, the keynote report "Healthy Environment, Healthy Humans" issued by the Second United Nations Environment Assembly and the report "Preventing Diseases through a Healthy Environment-Global Disease Burden Due to Environmental Factors" issued by the World Health Organization both showed that in 2012, about 12.6 million people worldwide died due to environmental factors, accounting for 23% of all deaths, a decrease of 1% compared with 2002. Among them, the death of non-communicable diseases due to the environment increased from 17% in 2002 to 22% in 2012, and the death of infectious diseases decreased from 31% in 2002 to 20% in 2012. The report mainly considers eight categories of environmental risk factors, such as occupational risk, environmental air pollution, vector environmental management, indoor air pollution, second-hand smoke, residential radon, lead and water (including drinking water, sanitation facilities and hand hygiene), and mainly considers 68 diseases that are significantly related to environmental factors, such as respiratory diseases, cardiovascular diseases, cancer, diarrhea, asthma and malaria.　

　　There are many reports about outdoor air pollution, cancer villages, children’s blood lead poisoning and campus poisonous runway events in China. Dr. Wei Zhengzheng from the Environmental and Economic Policy Research Center of the Ministry of Environmental Protection told the reporter of Life Times that there are still some long-term health hazards that may be caused by long-term low-dose exposure of pollutants, such as infertility caused by environmental endocrine disruptors, birth defects, and early development of adolescents. In urban and rural areas, environmental sanitation problems are becoming more and more obvious. Industrial pollution, agricultural pollution and domestic pollution are the main reasons for the deterioration of environmental sanitation, and most of them are man-made. Keeping the environment clean, reducing the breeding of parasites and germs, and cutting off their contact with people can reduce the occurrence of diseases.

　　A large area of cultivated land is polluted by pesticides to varying degrees.

　　With the development of rural economy, rural environmental pollution has attracted attention. Huang Jikun, director of the Agricultural Policy Research Center of Chinese Academy of Sciences, and others investigated the basic situation of environmental pollution in 101 villages in five provinces of China. The results show that 44% of the villages have deteriorated in the past 10 years, and factors such as the development of rural township enterprises, urbanization or the concentration of population residence have a significant negative impact on the rural environment. Wei Zhengzheng said that the main environmental health problems facing rural areas at present are water pollution, random stacking of domestic garbage and farmland soil problems.　

　　"Drinking irrigation in the 1960s, washing rice and vegetables in the 1970s, and the water quality deteriorated in the 1980s, and now it is black and smelly", which is a true portrayal of the changes in rural water environment. Domestic garbage in rural areas has developed from perishable vegetable leaves and peels to plastic bags, agricultural production films, fast food boxes, waste batteries, etc. Many of them are unrecoverable and non-degradable, which seriously pollutes the environment. A large area of cultivated land has been polluted by pesticides and toxic and harmful substances to varying degrees, mainly from industrial and urban sewage discharge, excessive and unreasonable use of pesticides and agricultural films in farmland, high environmental hormone content in large-scale livestock and poultry farms, and livestock manure, which has affected crops.　

　　To solve rural environmental problems, Wei Zhengzheng said that it is necessary to deal with solid wastes such as rural garbage, human and livestock manure, domestic garbage, domestic sewage and production wastewater, as well as the reduction and rational use of chemical fertilizers, and the control of pesticides and organic matter. First, thoroughly clean up all kinds of accumulated garbage in the village streets, in front of the house and behind the house, around the village and in public places, eliminate sanitary corners and have no exposed garbage. Clean up the floating objects and all kinds of sundries on the water surface of river ponds and ditches in villages, remove the indiscriminate construction, misplacing and illegal planting on the banks of rivers, and stop the sewage and feces from being discharged directly into rivers, enterprises exceeding the standard and burying rivers; The second is to establish a fixed garbage dump to realize centralized stacking and regular removal. Vigorously promote the rural garbage disposal mode of "household collection, village concentration, township transfer and county treatment", collect villagers’ domestic garbage and transport it to township transfer places in a centralized way. Conditional village, to establish a rural part-time cleaning team, set up a special garbage bin; Third, the management of human and animal feces, the implementation of harmless sanitary toilets. It is forbidden to defecate anywhere, the open pit should be covered, the excrement and urine should be disinfected by lime or bleaching powder for centralized treatment, and poultry and livestock should be kept in captivity to prevent their feces from polluting the environment and water sources. Keep the barn dry to reduce the chances of parasites and germs breeding; Fourth, take the development path of ecological agriculture, implement ecological balanced fertilization technology and ecological prevention technology, and control the use of chemical fertilizers and pesticides from the source. Combined with water-saving irrigation technology, improve the efficiency of agricultural water and fertilizer utilization.

　　Citizens should not blindly oppose the construction of waste incineration plants.

　　Not only rural areas, but also urban environmental sanitation needs urgent attention. According to the data of National Bureau of Statistics, the urbanization rate of China has reached 57.35% in 2016. With the rapid development of cities, urban environmental problems are also developing rapidly. Urban air pollution, indoor air pollution, urban water shortage and water pollution, urban waste and garbage pollution have seriously affected people’s production and life.　

　　Global Burden of Disease Assessment in 2010 shows that outdoor PM2.5 air pollution caused 1.2 million premature deaths and more than 25 million years of healthy life in China in 2010. Gas burning pollution, industrial waste gas, dust from construction sites and motor vehicle exhaust have become the main air pollution sources in China. Excessive discharge of industrial wastewater and a large amount of domestic wastewater have been discharged into rivers without treatment. 78% of the river sections in China are not suitable for drinking water sources, and 50% of groundwater is polluted. Many cities such as Beijing and Xi ‘an have also experienced water supply crises. It is estimated that China’s annual economic losses caused by pollution amount to 40 billion yuan. The growth rate of urban solid waste is far greater than the carrying capacity of the environment. In 2015, the output of urban industrial solid waste in China was 1.91 billion tons, and the output of domestic waste was about 18,600 tons, which increased at the rate of 7%~8% every year. Two-thirds of the cities in China were surrounded by garbage. The accumulation of solid waste everywhere not only hinders the view, occupies land and spreads diseases, but also seriously pollutes the environment and intensifies the pollution of water, atmosphere and soil.　

　　Wei Zhengzheng said that the government and the public should take action to deal with urban environmental sanitation problems. First, we should actively participate in the prevention and control of air pollution, use clean energy as much as possible, build clean heating projects, give priority to public transport, reduce traffic exhaust emissions, and actively promote the use of new energy and fuel alternative vehicles; Second, pay attention to indoor air, choose green decoration materials, strengthen indoor ventilation, keep the living place and surrounding environment clean, often clean the sanitary corner, try to keep the residential room dry and reduce the reproduction of germs; Three, advocate water conservation, encourage the reuse of wastewater. Use various natural purification methods to treat sewage, and adopt new technologies and methods to purify water, so that sewage cannot be directly discharged into rivers, lakes and seas; Fourth, vigorously support the recycling and comprehensive utilization of garbage resources. The citizens should actively participate in garbage sorting and recycling, understand the two main ways of municipal solid waste disposal, landfill and garbage incineration, do not blindly oppose the construction of garbage incineration plants, support garbage incineration power generation to turn waste into treasure, and assist in supervising the operation and sewage discharge of garbage incineration plants. ▲

　　Before the text begins, let’s talk about digression ~

　　Do you believe there is a "curse" in this world?

　　In the 1970s, there was an "explosive" news that shocked the world.

There have been successive "accidents" in the family.

Truth is far more terrible than "curse"

　　In the year of the end of the Vietnam War, an American Navy colonel named Yi Zhan Mu Walter returned to his motherland from Vietnam with his son, Captain.

　　After reuniting with relatives and friends, their family’s life is back on track.

　　Soon after, my son also met his soul mate and married and had children successfully.

　　I thought that it runs in the family’s happy life was just about to start, but unexpectedly, bad luck quietly fell on this family.

　　The little grandson was born, and before everyone could celebrate the joy of the new life, they were told that the child had congenital mental retardation.

　　Almost at the same time, my son was diagnosed with cancer and died soon.

　　Once, it can be said that it is accidental, and twice, it is a bit creepy … …

　　The family suffered successive changes, and the father lost his head overnight. He couldn’t figure it out. Maybe this family was cursed?

　　He hasn’t come out of the shadow of the loss of his beloved son, and he has made an amazing discovery by accident — —

　　The Vietnam veterans who returned home with him also seemed to be "cursed".

　　Laryngeal cancer, lung cancer, prostate cancer and other different cancers "explosively" destroyed his comrades.

　　And most of their descendants have serious congenital diseases or defects.

　　A series of sudden accidents are strangely similar. However, what I Zhan Mu Walter didn’t expect was that the truth is far more terrible than "curse" … …

A first-class carcinogen known as "the poison of the century"

600,000 people have been "pitted" and you have it in you.

　　During the Vietnam War, because the Viet Cong guerrillas used dense forest vegetation as a cover, the American army could not find the north.

　　Later, the US military made a "dirty trick" — — Sprinkle a lot of defoliants in the air (that is, "orange agent", which can make all the trees fall and nothing grows in a short time), so that the Viet Cong guerrillas have nowhere to hide.

　　The tropical rain forest sprayed with defoliants has suddenly become a bare "dead zone".

　　The question is, what does it matter that American Vietnam veterans and their descendants have one accident after another?

　　It turns out that this kind"agent orange"In the later investigation, was found.containHighly toxic substance — — Dioxin.

　　I Zhan Mu Walter and his sons, including his comrades-in-arms and descendants suffering from cancer, were not "cursed" but "pitted" by highly toxic dioxin.

　　However, compared with American veterans who were accidentally injured by this "carcinogen", Vietnamese local people are the biggest victims.

　　The Vietnamese government conducted a survey in 2000, and the results showed that about 600,000 people in Vietnam fell ill due to exposure to dioxin residues in Agent Orange, and the children born were either premature, deformed or had neurological defects.

　　Do you think this is just a distant Vietnam war story?

　　No,dioxinThis kind of substance,In real life, it is actually very close to each of us!

　　In fact, dioxins are not an independent individual fighting alone, but a "big family" with 210 compounds.

　　Where did it come from and where will it go?

　　Unlike the confused human beings, this guy has a particularly wide "route" and a rather "wild" way.

　　95% of dioxins are generated from garbage incineration, and other sources include: automobile exhaust, paper making, pesticide production, chemical industry, smelting, forest fires and so on.

　　Through these channels, it floats in the air, enters the water and is "submerged" in the soil, which is inevitable and everywhere.

　　Under certain conditions, it can carry out the second round of "migration", and dioxins enter crops, chickens, ducks, geese, cattle, sheep and aquatic organisms through polluted rivers, lakes, seas, air and soil.

　　No way, no way. Is there dioxin in everything I eat?

　　Don’t ask, ask is there.

　　As a human being standing at the top of the food chain, it’s sad. Your body is the ultimate "gathering place" of dioxins.

　　However, the huge family "power" is not the most terrible. What is terrible is that it is not a good crop.

　　Not only is it listed as a first-class carcinogen by the International Cancer Center, but it also has a "domineering" Jianghu nickname — — The "poison of the century" is not easy to hear.

The toxicity is 900 times that of arsenic.

Can "lurk" in the human body for 11 years

　　People call it "the poison of the century", so there must be two brushes.

　　This guy’s big move, that’s "tough" every move. Five "magic weapons" of dioxin "family inheritance" — —

rank poison

　　How toxic is dioxin?

　　Among them, the most toxic 2,3,7,8-TCDD is 900 times as toxic as arsenic! It is 1000 times more toxic than potassium cyanide, which is "dead at the entrance"!

　　Known as the most toxic poison on earth, it is listed as:Human primary carcinogen.

Tenacious vitality

　　This guy can "live" anywhere, can constantly migrate in the environment, from the atmosphere to the soil and water, and then accumulate layer by layer through the food chain, and these dioxins will eventually be "collected in full" by human beings.

"scourge" takes a long time.

　　Once in the human body, the half-life of dioxins in the human body can be as long as 7-11 years. What do you mean, half-life? That is to say, even if you don’t ingest dioxin again, it will take 7-11 years to reduce the concentration of dioxin in your body by half.

　　Moreover, at present, it is almost impossible to get rid of this "ghost" guy. After all, you can’t eat without drinking water.

Less water, more meat.

　　? ? ? Love meat. What did I do wrong? Will it be more favored by cancer? I am withered.

　　Here @ Old Tiers who love meat, eat more a la carte and coarse grains. This is the key point to be tested.

　　PS: Straight men who can only say "drink more hot water" have found another excuse.

Even "that aspect" is not spared.

　　Yes, literally, it’s a question of "that aspect", is it that the whole person is not good ~

　　Dioxin can cause irregular menstruation, endometriosis and ovarian dysfunction in girls; Boys are weak in sperm and less in sperm, and the shape of "balls" changes.

　　Stop talking, it’s all tears.

　　In fact, this notorious "family" has a multi-system and multi-faceted toxic effect on human beings. In addition to affecting "that aspect", there may beTeratogenesis, developmental toxicity, hepatotoxicity, skin damage and decreased immunity increase the risk of infectious diseases.Wait a minute.

　　And there is no doubt about his carcinogenicity. Studies have shown that the cancer mortality rate of workers exposed to high concentrations of dioxin for a long time is 60% higher than that of ordinary people.

　　of course，All talk about toxicity without dose is hooliganism.Although it is highly toxic and widely distributed, it is generallyLow levels exist in the environment.!

　　However, this does not mean that we can challenge the bottom line of this "big family" unscrupulously. Avoiding long-term exposure to high-dose polluted environment requires everyone’s efforts.

　　Brother dei, if you don’t want to gamble with your life, just listen to my advice — —

4 strokes to "save your life"

Cut off the "rations" of tumors

01. Eat a balanced diet

95% of dioxin in human body comes from food.Especially animal foods such as meat products, dairy products, fish and shellfish.

　　What should I do? Don’t eat? That’s definitely not possible. You think it’s immortal!

　　Eat, or eat! But eat healthily. The secret of health is nothing more than:Diversified diet, balanced nutrition, coarse grain collocation, and mixed meat and vegetables.

　　(PS: The content of dioxins in fruits and vegetables is much lower than that in meat, and eating more vegetables is also beneficial, which will bring dioxins attached to the intestines out of the body with Baba).

02. Avoid high-temperature stir-frying, and choose an oil-free pan.

　　When the oil is just right, the dishes are served, and the kitchen is filled with smoke. It’s a "hot dance" of food on the pot, stir-fry for three or two times, and then go out! Chopsticks in your hands are irrepressible … …

　　Stop! I don’t know. It’s dangerous?

　　When cooking, high-temperature frying is easy to produce a lot of oil smoke, which is an excellent opportunity for dioxin to "carry on the family line".

　　Although I know that many people may be "seeing is doing", I still want to say:Try not to stir-fry, and if possible, you’d better buy another oil-free pan.

03. Buy plastic wrap and plastic crisper.

　　When purchasing plastic wrap and plastic bag, try to choose PVDC material.

　　And plastic boxes can’t be bought casually. Usually, there will be a triangular circular sign at the bottom of the box. Choose.Plastic box with the number "5" for recycling.

　　When heating food in the microwave oven, you should also avoid covering it with plastic wrap, and try to choose a special microwave heating bowl.

04. Do a good job in garbage sorting

　　In the process of garbage incineration, plastics and metals together are the most likely to produce dioxins.

　　One of the meanings of garbage classification is to deal with different kinds of garbage in a targeted way to minimize the harm to the environment.

　　Also, plastic bags should be used as little as possible.Take an environmental protection bag with you when you go shopping.You are the most beautiful boy in the whole gai!

Can’t anyone deal with this bully?

　　Although dioxin seems to be "powerful", no matter how evil it is, it can’t escape a person’s "eyes" and palm!

　　This person is Dr. Zhang Jianqing — — Director of Persistent Organic Pollutants (Dioxins) Research Office of Shenzhen CDC.

　　In 2001, Shenzhen CDC took the lead in establishing the first food dioxin detection laboratory in China’s health system, and Dr. Zhang Jianqing became the leader of the laboratory. Since then, Dr. Zhang Jianqing’s team is destined to be the "lifelong enemy" of dioxins.

　　Over the years, Dr. Zhang Jianqing’s team has been investigating the background of dioxins in the environment and food, making full preparations for the formulation of dioxin content standards.

　　While guarding the people’s "safety on the tip of the tongue." In 2004, the Ministry of Agriculture imported a feed additive produced in the United States. After testing by Dr. Zhang Jianqing’s team, it was found that the dioxin content exceeded the EU limit standard by 117 times. After receiving the report, the Ministry of Agriculture returned the batch of products, effectively preventing highly polluted food from flowing into the people’s table from the source.

　　Actually, there is no absolute "zero pollution" in the world.

　　Harmful substances such as dioxins need a "bottom line" to regulate. As long as they "do not exceed the standard", there is no need to talk about it.

　　Reduce the content of harmful substances in the environment

　　It takes everyone’s efforts.

Traffic law enforcement was once unable to effectively target

Cheng Xinghuan, a reporter from Jinyang. com, reported: On the Guangdong Minsheng Hotline today (28th), Wang Fumin, deputy director of Guangdong Province, revealed that at present, more than 20 online car rental platforms have obtained business licenses in Guangdong Province, and 52,260 online taxi driver’s licenses and 50,138 online taxi transportation licenses have been issued, accounting for 17.7% and 30% of the national total respectively, ranking first in the country. However, in the management of online car, Didi Chuxing, a monopoly, has refused to accept data access for supervision, both in Guangdong and in the whole country.

However, for the rapid development of network cars, the supervision of the industry has lagged behind, especially in Yueqing, Wenzhou. On the evening of 26th, Guangdong Provincial Communications Department, Guangzhou Municipal Communications Commission, Shenzhen Municipal Communications Commission and Dongguan Transportation Bureau talked about Didi respectively. In Shenzhen, according to the network car data transmitted by Didi Platform to the government supervision platform (the ride data has not been transmitted), there are still nearly 5,000 drivers and nearly 2,000 vehicles in the platform that have not obtained the operating documents. In Dongguan, there are 19,492 drivers (including 15,584 drivers who obtained the taxi qualification certificate before November 2016), and only 5,204 vehicles have obtained the network car transportation certificate. However, Didi Platform has more than 30,000 drivers and more than 20,000 vehicles providing online car service in Dongguan.

However, even if the government departments intervened early, Didi still "went its own way". In the notification of the interview in Dongguan, the rectification measures promised by Didi Company have not been effectively implemented. For example, it promised not to distribute orders to non-Dongguan license plate vehicles from June, but some citizens still reported that non-Dongguan license plate vehicles would take orders at night. In this year, Dongguan investigated and dealt with 292 cases of illegal network car service, including 61 cases of illegal network car service provided by Didi Company. This number is not worth mentioning compared with the operation of nearly 10,000 driving without a license and 15,000 unlicensed vehicles.

As to why government departments can’t supervise these "black cars", Wang Fumin said that Didi refused to access data to government departments for supervision not only in Guangdong, but also in the whole country, and refused to provide detailed data on drivers and operating vehicles, so it was impossible to carry out targeted law enforcement and could only rely on the original containment. After the rectification of Didi at the end of September, all management departments will obtain the complete data uploaded by Didi, and then effectively retreat, which is expected to be completed before the end of the year.

In addition, after the Wenzhou Yueqing hitchhiking case, Wang Fumin predicted that the next step would be to introduce a policy to put aside the customer service and directly connect with the public security organs.

It is always difficult for people to remember the second and third, but they can always remember the first clearly.

You may forget what it feels like to hug the opposite sex for the second time, but you must remember the throbbing of the first hug. Just like you may not remember the second car you took and drove, but you are impressed with the first car.

So, do you remember what was the first car you sat in and drove? I believe most people’s answer is only three words:.

People who came from the era of "owning Santana and traveling all over the world are not afraid" always have a memory in their minds, that is, the square front, the VW logo carved on the plastic grille and the classic "Shanghai Volkswagen" tail logo …

When the time train galloped past forty platforms, the meaning of "SAIC Volkswagen" was very different for China automobile industry and even everyone. During these forty years, SAIC-Volkswagen witnessed the rise of China’s automobile industry and the great achievements of reform and opening up. At the same time, it also gained its own prosperity as the first joint venture automobile company in China.

Yesterday, SAIC Volkswagen opened a neon for the China auto market.

Let’s temporarily adjust the time back to the time node that crossed in the 1970s and 1980s.

At that time, there were not many small cars running in China, except for Beijing 212 and Shanghai brand cars. Old friends who came from that era probably have the impression that there are always several dark green 212 cars and several white or blue-green Shanghai cars parked in the tree-lined government compound.

In that era when the global automobile industry entered prosperity, China automobile industry can still be described as "barren".

After the tide of reform and opening up came, the state decided to vigorously develop the automobile industry. So in 1978, China made initial contact with German audi ag. After many arguments, in 1984, Shanghai Car Factory and German Volkswagen formally signed the joint venture and cooperation regulations, and the two sides jointly established Shanghai Volkswagen Co., Ltd.

The first car introduced into China market by Shanghai Volkswagen Joint Venture Company is the "Santana" which will be popular all over the country in the next 30 years. However, as the first joint venture car in China, Santana’s landing road is also quite tortuous.

China in the 1980s did not have a modern automobile industry base. Therefore, the first batch of Santana cars launched by Shanghai Volkswagen for the China market can only be produced by CKD parts imported and assembled. On the assembly line, the workers of Shanghai Volkswagen can only assemble the whole vehicle by hand.

In fact, while bringing Santana, Shanghai Volkswagen also shoulders an important mission, which is to bring advanced production technology and manufacturing technology of western automobile industry to China after the establishment of the factory. In other words, Shanghai Volkswagen shoulders the responsibility of "starter" of China Hyundai Motor Industry.

After a period of "extensive production", Shanghai Volkswagen invited experts from German Volkswagen to Shanghai for guidance in order to improve production capacity and efficiency, and introduced international manufacturing standards and production equipment. Through the intensive production line upgrade, Shanghai Volkswagen has increased the annual production scale of Santana to more than 50,000 vehicles in just six years. However, at this time, Shanghai Volkswagen still lags behind the development goal of "within 7 years, the localization rate of Santana will exceed 80%".

Then, after establishing the modern production process and manufacturing technology, the next plan of Shanghai Volkswagen is to establish a complete automobile supporting supply chain industry in China based on Santana.

In the TV series Blossoms Shanghai, No.120 Jinxian Road left an impression on the audience.

In reality, No.120 Jinxian Road is the original site of Shanghai Piston Factory. When Shanghai Volkswagen was determined to establish a modern automobile supply chain system, Shanghai Piston Factory signed a technology license transfer contract with German Kolbenschmidt Co., Ltd. to introduce piston manufacturing technology to purchase key manufacturing planes and test equipment.

Starting from the piston factory, Shanghai Volkswagen has also established a large number of spare parts suppliers since the 1990s, and established quality standards in China that meet German Volkswagen and international standards. At this point, China automobile supply chain industry has also entered a stage of prosperity and development.

It can be said that Shanghai Volkswagen, which started in the 1980s, not only brought brand-new Santana cars to the China market, but also brought a brand-new beginning to the automobile industry in this ancient land.

This joint venture car company is the first to introduce foreign capital, global standards and advanced manufacturing systems into China’s automobile industry. To some extent, the development history of Shanghai Volkswagen is the development history of China automobile industry marketization. As a pioneer of the whole industry, Shanghai Volkswagen is worthy of the title of "industry beacon".

Today, SAIC Volkswagen sets an industry benchmark with tens of millions of trust.

Today, the production and sales scale of SAIC Volkswagen has already exceeded 10 million, and it has become the first passenger car enterprise in China with a cumulative output exceeding 28 million. 40 years, 28 million, these data reflect the stable and prosperous development of SAIC Volkswagen.

Today, SAIC Volkswagen has three brands, Volkswagen, Audi and Skoda, and continues to play a leading role as a joint venture car company with an annual sales of one million. Of course, the achievements made by SAIC-Volkswagen in the past 40 years are not only remarkable achievements in the market.

More importantly, SAIC Volkswagen has always created a new situation in the automobile industry.

If we say that during the period from the 1980s to the 1990s, SAIC-Volkswagen was introducing advanced technologies from the western automobile industry to help China’s modern automobile industry grow sturdily; Then, during the period from 2000 to 2000, SAIC Volkswagen made more wonderful contributions to the automobile industry with its own progress.

Since the Santana 2000 project at the beginning of the new century, SAIC-Volkswagen has started the road of independent research based on the global technical and design advantages of Volkswagen and the actual demand of China local market. As the first joint venture car company in China, SAIC Volkswagen has also become the first joint venture car company in China to independently develop new models.

When SAIC Volkswagen has the tradition of independent research, it has brought many refreshing products.

Volkswagen, through its insight into the needs of domestic household consumers, has created a large-space body and brought a quality experience to a total of 5 million home users; Volkswagen, on the other hand, deeply observes the young user groups and has become a travel partner of more and more young people with high value built by face value and performance; Volkswagen, as a large-size SUV with superior volume, is deeply favored by domestic middle and high-end users, and has gone abroad to dominate the North American market under the name of Atlas.

In fact, SAIC Volkswagen has many self-developed models, such as today’s L Pro, which not only brings a new experience to domestic consumers. More importantly, this new car pioneered the in-depth cooperation between SAIC Volkswagen and DJI, a China science and technology enterprise, and helped SAIC Volkswagen, which has a history of 40 years, formally enter the intelligent era with its intelligent performance comparable to that of new forces.

"Innovation" is the best summary of SAIC Volkswagen today.

From self-developed models to the development of advanced intelligent technology, SAIC Volkswagen has been at the forefront of the times every time. Undoubtedly, with the spirit of innovation as the basis of enterprise development, SAIC Volkswagen will definitely open up a new situation in the future.

What will the future of SAIC Volkswagen look like in 2040?

On the 40th anniversary of the establishment of SAIC Volkswagen, SAIC Motor Group, which came from Shanghai Car Factory step by step, signed an extended joint venture agreement with audi ag. According to the agreement, the joint venture period of SAIC Volkswagen will be extended for another 15 years to 2040.

The decision of the two parties to the joint venture also directly opened the door to the future for SAIC Volkswagen. We can’t help wondering what kind of situation SAIC Volkswagen will create when the era of intelligence and electrification comes.

The pulse of the times is constantly beating, and SAIC Volkswagen is always moving forward. As early as 2021, when, and ID.3 slowly drove off the production line of Anting MEB factory, SAIC Volkswagen opened the prelude to the future.

It can be seen that in the face of the surging intelligent electric era, SAIC Volkswagen has actively planned the enterprise transformation layout. At the same time, the three major ID. series models built on MEB platform have stood firm in the joint venture camp. In November, SAIC Volkswagen ID.3 delivered more than 14,000 new cars and became the king of pure electricity sales among joint venture brands.

When SAIC Volkswagen’s new energy pace is getting faster and faster, this joint venture car company has also begun to think about a "philosophical question" that all traditional car companies must consider-facing the future, should we take the new energy route or keep the fuel route?

SAIC Volkswagen, which has developed for 40 years, has already accumulated a strong system strength, and the answer it brings is "all want". In the field of fuel vehicles, SAIC Volkswagen is committed to promoting environmental protection, high efficiency and intelligence of fuel vehicles. After popularizing more efficient 300TSI power, SAIC-Volkswagen also launched the strategy of combining oil with electricity. The Volkswagen Tiguan L Pro, which has the same intelligent performance as the smart electric model, has also become a popular model at present.

Based on the sales support of fuel vehicles, SAIC Volkswagen can also explore the new energy field more quickly. In November 2024, SAIC Volkswagen launched a brand-new luxury brand AUDI on the basis of Audi, and made its debut in the first concept car. After starting the alphabet, SAIC Volkswagen will further promote the transformation of high-end new energy.

It is reported that AUDI’s first new car, AUDI E, was designed by Audi’s German team. At the same time, the core three electrical components and intelligent system of this car came from SAIC Volkswagen’s supply chain system. In the close cooperation between SAIC and Volkswagen, we believe that the brand-new AUDI brand can create intelligent electrification products with strong strength for China users.

Of course, SAIC Volkswagen also showed a faster speed.

In 2025, AUDI E, the first model of the new brand, will be delivered in mass production. At the same time, within three years, the AUDI brand under SAIC Volkswagen also plans to launch three electric vehicles, covering the B-class market and the C-class market, and quickly seize the high-end smart power camp highland.

Conclusion:

?

From the time when the first Santana was produced by knocking, to the time when Pro/ Tiguan L Pro and other models were rolled off the assembly line from a clean and tidy smart factory, SAIC Volkswagen took 40 years to set countless firsts in the history of China automobile industry.

I believe that many friends’ love for SAIC Volkswagen comes from their feelings. But what the author wants to say is that when we get out of the feelings of the years and the memories of the past, SAIC Volkswagen has always been a trendsetter standing on the top of the wave.

Nowadays, what SAIC Volkswagen is facing is not only the glory of the past forty years, but also the opportunity of the next fifteen years and the next fifty years. We are also willing to believe that in the next era, SAIC Volkswagen will bring us more touches and more surprises.

　　[rumor]

　　◎ Our reporter Chen Xi

　　These days, there has been a cold wave weather in China, and the temperature in most areas has plummeted. The cold wave not only affected a wide range, but also was accompanied by rain and snow.

　　Some rumors related to winter have also taken advantage of this cold wave to brush a wave of "existence": "triple" La Nina brings three times the cold, velvet is the warmest clothing material at present, the longer the car is hot in winter, the better, and the frost on persimmon is a preservative … … These rumors mislead the masses and have a negative social impact.

　　Today, the reporter of Science and Technology Daily took stock of the rumors in November one by one and smashed them with the power of science.

　　"Triple" La Nina brings triple cold?

　　Truth: La Nina is just one of the factors that affect winter temperature.

　　According to the latest data released by the World Meteorological Organization, the La Ni? a event that has lasted for a long time (hereinafter referred to as La Ni? a) is likely to continue until the end of this year or longer, which will be the first time in the 21st century that there will be a "triple" La Ni? a, that is, there will be three consecutive La Ni? a winters in the northern hemisphere.

　　As soon as the news came out, it immediately attracted widespread attention, and some netizens gave their own "interpretation": "triple" La Nina will definitely bring three times the cold.

　　In this regard, Zhou Bing, chief expert of climate service of National Climate Center, said that "triple" La Nina is not triple La Nina. "Triple" La Nina means that three consecutive winters from 2020 have been affected by La Nina. The impact is not constantly superimposed year after year, nor does it mean that the climate impact will double year by year.

　　La Nina refers to the phenomenon that the sea surface temperature in the eastern and central equatorial Pacific Ocean continues to be abnormally cold, also known as the anti-El Ni? o phenomenon. When La Nina appears, it is usually accompanied by global climate chaos. At this time, China is prone to cold winter and hot summer, and the number of tropical cyclones landing in China will be more than normal, resulting in the phenomenon of "drought in the south and waterlogging in the north". In Indonesia, eastern Australia, northeastern Brazil and other places, there will be more rainfall; The equatorial regions of Africa and the southeastern United States are prone to drought.

　　In the winter when most La Nina reaches its peak, the cold air that affects our country will appear more frequently. According to statistics, from 1990s to February 2022, in autumn and winter when La Nina appeared, cold air affected China 141 times, of which 27 times reached the level of cold wave.

　　"However, there are many factors that determine the temperature in winter, and La Nina is just one of many factors." Zhou Bing emphasized that the winter temperature in China is not only closely related to the intensity of winter monsoon in East Asia, but also related to factors such as Arctic sea ice, Eurasian snow and atmospheric circulation system. Therefore, although there is a greater probability of cold temperature in La Nina’s winter, it does not mean that there will be cold winter.

　　After 1986, the frequency of "meeting" between La Nina and warm winters increased, among which 1998 and 2020 were strong warm winters. The National Climate Center pointed out in the Forecast of Climate Trends in Winter 2022/2023 and Spring 2023 released on November 3, 2022 that it is expected that the cold air intensity affecting China will be weak in general this winter (December 2022 to February 2023), and the temperature in most parts of the country will be close to the same period of the year or high.

　　Experts from the National Climate Center said that climate prediction is a highly professional scientific research business, which needs to be based on a large number of climate observation data and supported by high-resolution numerical forecasting products, so as to conduct comprehensive judgment and analysis, and finally draw scientific conclusions cautiously.

　　Deron is the warmest garment material at present?

　　Truth: There are many materials similar to its warm-keeping effect.

　　As soon as the weather turns cold, many people begin to buy thermal underwear. Go to the e-commerce platform to search for "thermal underwear", and many products have the words "Derong" on their packages. Derong has almost become the most frequent thermal clothing material this year. Many related businesses claim that Deron can generate heat by itself, and it is the warmest garment material at present.

　　So, what is the truth?

　　"Deron is a transliteration of the English word Dralon, which is an acrylic fiber developed by an international life science group in Germany. The main component is polyacrylonitrile fiber." Xu Lei, an associate professor of tianjin polytechnic university Textile Science and Engineering College, said in an interview with Science and Technology Daily that Deron is not a new thing, and it entered the Chinese market as early as 2011.

　　"Derong’s principle of keeping warm has nothing to do with self-heating, but is mainly related to the thermal conductivity of air." Xu Lei said that the thermal conductivity of an object represents its ability to transfer heat, and the low thermal conductivity of air means that its ability to transfer heat is low, that is, heat is not easily lost, so the more air the fabric can store, the better its warmth retention effect. Deron’s cross-section is double-T-shaped, which not only makes the fabric fluffy and thick, but also enables it to "lock" more still air, thus forming an insulation layer and reducing the heat dissipation of human body.

　　"However, ‘ Deron is the warmest garment material at present ’ The statement is incorrect. " Xu Lei said that although the thermal conductivity of Deron is only 0.05 W/m Kelvin, which is relatively low among thermal insulation materials, there are many materials with similar thermal insulation effects among fiber materials.

　　In addition, the moisture absorption performance of cashmere is also relatively general. In contrast, cashmere material is also very warm, and it is soft, comfortable, hygroscopic and elastic. Another example is the down jacket, whose high bulkiness can also retain a large amount of static air, thus playing a warm role and not easily generating static electricity.

　　Is the frost on persimmon a preservative?

　　Truth: Frost is a natural persimmon frost.

　　Persimmon is a cake-like food made of persimmon, and it is also one of the most anticipated foods in winter. Everyone who has eaten persimmon knows that there is more or less a layer of white powder on persimmon, but most people don’t know what this layer of frost is, so it is circulated on the Internet that it is an artificially added preservative.

　　In this regard, Tian Shufen, a professor from tianjin agricultural university, said in an interview with the Science and Technology Daily that the white frost on persimmon is called persimmon frost, which is a naturally formed icing in the production process of persimmon, and is not a preservative, which is harmless to the human body, and consumers can safely eat it.

　　When making persimmon, you need to peel the persimmon first, and then dry the peeled persimmon. In the process of drying in the sun, persimmon will separate out nutrients such as fructose and glucose. After the water evaporates, these nutrients will gradually accumulate and crystallize, and finally persimmon cream will be formed.

　　"Persimmon cream has the effects of moistening lung, relieving cough, stopping bleeding, promoting fluid production and relieving sore throat, and has certain curative effect on symptoms such as sore throat and cough." Tian Shufen introduced that persimmon cream is rich in vitamin B_2, which also has a certain therapeutic effect on aphtha.

　　Generally speaking, the amount of persimmon cream on the outer layer of persimmon is determined by the temperature and drying time. The colder the weather and the longer the drying time, the sweeter the persimmon will be and the more persimmon cream will be. In the process of storage and transportation, if the ambient temperature rises, persimmon frost may melt and become less, which is what we often call "returning frost".

　　However, consumers don’t need to excessively pursue the amount of persimmon cream. They need to be wary of unscrupulous merchants who artificially sprinkle flour, starch and other substances on persimmon in order to improve the "face value" of persimmon. After artificial "whitening", the persimmon looks even, but as long as it is shaken gently, the white powder on it will fall off, and its taste is not the sweet feeling of persimmon cream.

　　The longer the car is hot in winter, the better?

　　Truth: Overheating a car can damage the engine.

　　Before exercise, people usually warm up in advance in order to reduce the harm caused by exercise. Before a car runs, it also needs a "hot car". Experienced old drivers know that in winter, after the car is started in outdoor low temperature environment, it needs to run at idle speed (make the car engine run in neutral position) for a period of time before driving normally.

　　Recently, however, many people said that the longer the warm-up time is, the better, because it is too cold outdoors in winter, which can make the engine warm up more fully.

　　Does this statement make sense?

　　In this regard, Liu Jun, a teacher from the School of Automotive Engineering of Tianjin Vocational College, said in an interview with the Science and Technology Daily reporter that in winter, due to the low outdoor temperature and poor fuel atomization, it is best to gradually heat up the engine when starting it outdoors, and it is not appropriate to use the engine with accelerated and afterburner, so as to reduce the wear of the engine and improve fuel economy.

　　In addition, under the condition of low temperature, the fluidity of engine oil will decrease and the viscosity will increase, so it is difficult to lubricate the engine quickly. Therefore, it is necessary to warm up the car before driving in winter, but the damage to the car caused by excessive warm-up is not small.

　　"There are two main aspects of the damage to the car when the hot car is too long. First, it will make the engine produce carbon deposit (a burnt substance produced by unsaturated olefin and gum in fuel at high temperature during engine operation), which will further affect its performance, especially shorten the service life of engine spark plugs. Second, in the process of idling, the fuel concentration is high, and idling for a long time will waste fuel, increase pollutant emissions, and increase the workload of three-way catalytic converters and particle traps (OPF). " Liu Jun explained.

　　For pure electric vehicles, Liu Jun reminded that the driving device of electric vehicles is mainly composed of motors, power batteries and control systems, and the energy for driving pure electric vehicles comes from batteries, so there is no hot car problem. However, it should be noted that the hybrid vehicle needs to be warmed up. When its mileage exceeds the cruising range in pure electric mode, it needs to be switched from pure electric mode to fuel mode. At this time, if it is not warmed up, it will also damage the engine. Therefore, in this case, the driver had better warm up the car in fuel mode before driving normally.

　　The "White Helmet" is a Syrian civil defense organization. Because its members often wear a white helmet in rescue activities, it is also known as the "white helmet". The organization has repeatedly discredited the Syrian government by video fraud. A number of American media disclosed that the United States is an important supporter of the organization.

　　In November 2016, the NGO "White Helmet" admitted that the previously released video of the organization’s staff rescuing the wounded in Aleppo, Syria was a pose and issued an apology statement. In September 2018, the Russian Ministry of National Defense issued a statement saying that Syrian anti-government militants once again staged a fake scene of "being attacked by chemical weapons."

　　In 2018, as the Syrian government forces regained more and more territory, the United States negotiated with its allies to help the "white helmet" withdraw from Syria. In 2019, then US President Trump publicly ordered to provide the organization with $4.5 million in aid.

　　Faking, posing and acting, the United States is directing all this behind the scenes. However, he was not born in a class, and his poor acting skills were frequently seen through and exposed. The so-called non-governmental civil defense organizations are actually a group of American servants under the banner of humanitarianism. The United States tries to interfere in other countries’ internal affairs by subsidizing non-governmental organizations, and its hegemonic essence is obvious.
