China Weather Network News Affected by surface cyclones, severe convective weather occurred in many places in Jiangsu yesterday (July 20th), among which Suqian Shuyang and Lianyungang Guannan were even hit by tornadoes. As a small-scale weather system, tornado has a short life, but it is extremely destructive. It comes as soon as it comes, and people can’t avoid it. Is there a rule for tornadoes to follow? China Weather Network analyzes meteorological big data to reveal when tornadoes are most frequent in China and which areas are more prone to them.

　　Tornadoes are extremely destructive and can blow cars and destroy houses.

　　Tornado, as a kind of strong destructive convective weather, is a small-scale air vortex produced under strong unstable weather conditions. The central wind force can reach 50-150 m/s, and the diameter is generally between several meters and hundreds of meters.

　　Tornadoes are generated and disappeared rapidly, often accompanied by strong convective weather systems such as thunderstorms, hail and heavy rain, which are extremely destructive. According to Fujita scale, the tornado strength is divided into six grades: EF0 to EF5, with EF0 being the lowest and EF5 being the highest.

　　Tornadoes of EF2 and above are generally called strong tornadoes, and EF2 tornadoes will cause considerable damage, which may lead to the uprooting of trees; EF3 tornadoes often cause serious damage, and trains may be blown down. EF4 tornado may cause destructive damage, good brick-wood structure and frame structure houses may be destroyed, and some houses will be shoveled and leveled by Qi Gen; The damage caused by EF5 tornado is devastating. The house with frame structure may be thrown out together with the foundation, the reinforced concrete structure building will be seriously damaged, and the car may be blown away.

　　Tornadoes have occurred in most parts of China, with the largest number in Jiangsu and Guangdong.

　　Global tornadoes mainly occur in mid-latitude areas, and tornadoes occur every year in North America, Europe, Russian Federation, China, Japanese and Australian, among which the United States is the country with the most tornadoes, with an average of 1,141 tornadoes recorded every year (from 2000 to 2020), which is called "Tornado Kingdom".

　　Tornadoes in China mainly occur in the eastern plain, and the middle and lower reaches of the Yangtze River are frequent areas. According to the statistical data of the National Climate Center from 1991 to 2020, there are 38 tornadoes every year in China, and there are more tornadoes in Jiangsu, Guangdong, Hubei and Anhui provinces, among which Jiangsu and Guangdong have the most tornadoes, with an average annual number of 4.8 and 4.3 respectively, followed by Hubei and Anhui, with two tornadoes.

　　Strong tornadoes occur frequently in spring and summer in China, and most frequently in July.

　　Spring and summer are tornado-prone seasons in China, and the number of tornadoes accounts for 92% of the whole year from April to August, with July accounting for the highest proportion, accounting for about 30%. Judging from the occurrence time of tornado of EF2 and above, it is also the most in July.

　　According to the statistical data of "Temporal and Spatial Distribution of loong Tornadoes", there were 165 tornadoes of EF2 and above in China from 1961 to 2010, and the occurrence time was mainly from April to August. Looking at a single month, July was the most, accounting for 28% of the total number of the year, followed by April.

　　In addition, the months of tornadoes in different regions are slightly different. South China frequently occurs from April to May, the middle and lower reaches of the Yangtze River frequently occur in April and July, North China frequently occurs from June to July, Northeast China frequently occurs from June to August, Southwest China mainly occurs from July to August, and Northwest China frequently experiences tornadoes in July.

　　Tornadoes prefer the afternoon and the evening.

　　In addition to seasonal differences, the time of the tornado’s haunting in one day also has certain rules, and the tornado prefers to "haunt" in the afternoon.

　　According to the statistical data of "Temporal and Spatial Distribution of loong Tornado", from 1961 to 2010, tornadoes occurred from 12: 00 to 20: 00, accounting for 70% of the total number of tornadoes whose time records can be found. The reason for the high incidence in this period is that the atmospheric stratification is unstable after daytime solar radiation, and strong convective weather is most likely to occur, which is easy to promote the formation and strengthening of tornado weather system.

　　In addition to the high-incidence period in the afternoon, the tornado often appears in the early hours of the morning. According to statistics, there are also 10 tornadoes generated from 0: 00 to 2: 00. Tornado occurred less in the morning, with the least occurrence from 10: 00 to 12: 00, only once.

　　There are 38 tornadoes in China every year, with a maximum of 75 in 2005.

　　Judging from the interannual changes, the periodicity of tornadoes is also obvious. According to the statistics of tornado data recorded from 1991 to 2020, there are an average of 38 tornadoes every year in China. There were relatively many tornadoes from the mid-1990s to the beginning of this century. There were relatively few tornadoes in the early 1990s and from 2006 to 2020. Among them, the number of tornadoes was the highest in 2005, reaching 75, and the least in 2020, only 13.

　　What should I do if I encounter a tornado?

　　Tornado is a kind of severe convective weather. After the tornado is formed, it usually lasts for ten minutes to several hours. Its attack range is small, but its destructive power is great. Once encountered, how should we defend ourselves?

　　First, if you are at home, be sure to stay away from doors, windows and the outer walls of houses, and hide in the wall or small room opposite to the tornado. The basement or semi-basement is the safest place to avoid the tornado;

　　Second, in the emergency of pole falling and house collapsing, the power supply should be cut off in time to prevent electric shock or fire;

　　Third, when there is a tornado outside the field, you should look for low-lying ground nearby, but stay away from trees, telephone poles, billboards, fences, etc. to avoid being smashed, crushed or electrocuted;

　　Fourth, when you encounter a tornado when you go out by car, you should drive in the opposite direction, or leave the car immediately and take shelter in a low-lying area.

????The British, German and French foreign ministers voiced their voices on the same day on the 17th, demanding a ceasefire in Gaza. Us defense minister Austin visited Israel on the 18 th and asked it to "reduce the scale of the war"; Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization, condemned the Israeli destruction of hospitals in northern Gaza; Pope Francis said that Israel uses "terrorism" strategy in Gaza; Non-governmental organizations accuse Israel of preventing food and water from entering Gaza and using hunger as a weapon of war … Agence France-Presse said on the 18th that with the death toll in Gaza approaching 20,000, Israel is facing increasing anger. The United Nations Security Council is scheduled to vote on a new draft resolution on the same day, which was proposed by Arab countries and called for an "urgent and sustainable cessation of hostilities" in Gaza. The British "Guardian" said that the new resolution put pressure on the United States not to use its veto power as a permanent member of the Security Council to protect Israel again. Earlier, the United States vetoed Security Council resolutions on the situation in Gaza twice.

????On the 17th, after the Rafah area in Gaza was attacked by Israeli troops, rescuers carried out search and rescue. (澎湃 image)

????European countries "change their tone"

????British Foreign Secretary David Cameron and German Foreign Minister Berber issued a joint article in the Sunday Times on 17th, calling for a "sustainable ceasefire" in Gaza. The New York Times explained that the two countries had changed their previous tone of supporting Israel. After Britain and Germany published an open letter, French Foreign Minister Collonna also called for an "immediate and lasting truce". According to the report, in recent weeks, due to the firm support of the United States, Israel has been protected from international pressure to a certain extent. Earlier this month, the United States voted against the UN Security Council resolution calling for a ceasefire in Gaza. But Washington changed its public tone in the past week. US President Biden criticized the Israeli military for "indiscriminate" bombing of Gaza and warned that Israel was losing international support. This is Biden’s harshest criticism of Israel since the current Palestinian-Israeli conflict broke out in October.

????Washington post said that the Israeli attack on medical institutions in Gaza was strongly condemned by WHO. Tedros Adhanom Ghebreyesus, Director-General of WHO, said on social media on 17th that the organization was shocked by the destruction of Kamal Adouan Hospital in northern Gaza, which was no longer operational, resulting in the death of at least eight patients, which was "a serious blow to Gaza’s paralyzed health system". According to WHO, the situation of Shifa Hospital, the largest medical institution in Gaza, is a "complete horror scene", and its emergency room is being staged with a "massacre", where the injured people are crowded, but the hospital has no corresponding medical conditions.

????Israeli military snipers were accused of shooting at a church in Jerusalem on the 16th, killing a Palestinian woman and her daughter who had taken refuge here, and injuring seven others, which also angered public opinion. Rome Pope Francis said on the 17th that Israel used the strategy of "terrorism" in Gaza, and there were no terrorists in the church, only children, the sick and the disabled. Italian Foreign Minister Taiani also voiced his concern on the 18th, saying that terrorists would definitely not hide in Christian churches, and Israeli actions would not help defeat Hamas. The Israeli military denied the allegations, saying that its findings showed that no civilians were killed in Christian churches.

????Israel is like a "bull in a China shop"

????Health authorities in the Gaza said on the 18th that Israeli attacks on northern Gaza had killed at least 151 Palestinians since the previous day. Since the outbreak of this round of conflict on October 7th, Israeli attacks in Gaza have killed 19,453 people.

????"No one ever foresaw this." The British Broadcasting Corporation (BBC) commented on the 18th that all Israel’s allies, including Britain, the United States and Germany, did not foresee that the death toll in Gaza would approach 20,000 when they pledged their full support for Israel and its right to self-defense on October 7th. "Voice of America" said that although the US government has provided important military and diplomatic support to Israel, it is increasingly uneasy about civilian casualties in Gaza. Senator Chris Van Hollen said in an interview recently that the high number of civilian casualties in Gaza is "unacceptable".

????Former British Defense Secretary ben wallace warned in the Daily Telegraph on 18th that the Israeli government’s "killing rage" in Gaza damaged its original legitimate right of self-defense, and it made a mistake, thus losing its moral and legal authority. Israel’s indiscriminate attacks on Palestinians may make the conflict last for another 50 years and make young Muslims around the world more radical.

????Wallace said in the article that he is not calling for a ceasefire, but Israel needs to "stop this rude and indiscriminate attack." He believes that "it is legal to pursue Hamas, but it is illegal to destroy a large area of Gaza; It is legal to use appropriate force, but it is illegal to collectively punish and force civilians to move. " He said that the behavior of Israeli politicians was "like a bull in a China shop".

????The U.S. Defense Secretary visited Israel again, "with tougher information and lessons learned."

????On the 18th, US Defense Secretary Austin and US Joint Chiefs of Staff Chairman Brown arrived in Israel. The New York Times said that this is Austin’s second visit to Israel since October 7th, and this time he "has more severe information and lessons learned". Biden administration officials are urging Israel to end its large-scale ground and air operations in Gaza within a few weeks. Austin’s message will be more direct: if more measures are not taken to protect civilians, Israel may face "strategic failure", which will make the country more insecure. This proposal comes from the experience of past military operations in the United States. According to the report, Austin will express his support for Israel, but at the same time, he will discuss with the Israeli leadership when and how to launch a "new stage of war", reduce the scale of the war in Gaza, and turn to elite troops to carry out precise strikes against Hamas.

????Daniel Levy, a former Israeli peace negotiator, told The New York Times: "This level of killing against civilians and the anger it aroused ensure that future generations inside and outside Palestine will be recruited as militants and support the resistance movement. This is a problem for Israel and the United States. "

????On the 18th, news spread that the heads of intelligence agencies of the United States and Israel and the Prime Minister of Qatar met in Poland, and all parties mediated a ceasefire between Israel and Hamas and resumed hostage negotiations. Regarding the prospect of war, Al Jazeera said that Yusef BuAndel, a professor of international relations at Qatar University, said that he was "optimistic" about reaching a new truce with the increasing pressure from home and abroad. According to the analysis of the Egyptian newspaper Izvestia, Biden’s government has to canvass for its election when there is a general demand for a ceasefire in Israel all over the world, especially when the Islamic countries are passionate. If Israel’s behavior is allowed to continue, Biden will lose the support of Muslims in the United States.?

appearance

Compared to iPhone 12, the appearance of the iPhone 13 can only be regarded as a small change. The same right-angled border, the same screen size and only 11g of weight make the iPhone 13 feel almost unchanged.

However, there is a small detail, all the key positions of the iPhone 13 are lower, and it is easier to press the button when operating with one hand, but this also leads to The protective case of the previous generation is not universal. .

iPhone 13 still supports MagSafe, we got a new card package this time, you can see the specific location in the search after binding, and you will receive a notification about its last location after separation, but it does not support UWB positioning like AirTag.

iPhone 13 appearance perception of the most obvious changes in two points, one is the lens module, the other is the color.

This is a blue iPhone 13, compared to iPhone 12 It’s more restrained, it looks more subdued. Low-contrast, low-saturation tones look more textured.

We also got the new midnight color, which is a true interpretation of what is called black in front of you, not black, say it is blue, it is so blue. Midnight color will have a deep blue under strong light, and there is a hint of racy hidden in the low key.

This year iPhone 13 color scheme has taken a more profound route, not as bright as last year, but the afternoon and starlight colors have added a little thought.

Another obvious change in the appearance of the iPhone 13 is the camera module, which is arranged 45 degrees diagonally mainly for Tuck a large sensor into a limited lens module It’s not about being different for the sake of being different.

However, this lens arrangement, coupled with the new color scheme, can still be recognized on the street as a new iPhone.

screen

iPhone 13 is still a 6.1-inch ultra-retina XDR display, look and feel basically the same as the previous generation.

However, its screen brightness has increased by 28% this time, and it also performs well in strong light, but it is a pity that it does not use the ProMotion adaptive refresh rate. High brush or exclusive to Pro series .

However, the smaller bangs have been treated equally, mainly due to the upward movement of the handset Sensors are more compact This allows for more space and larger icons on both sides.

Apple did not give the extra space to cram more icons, which ensures the consistency of the experience iOS different devices.

As for the impact of bangs on the use of smaller, in the iPhone 13 can be said to be basically negligible, after all, with the phone when the line of sight is mainly focused on the screen to the lower part, most of the time will not notice these two places, iPhone 12 mini users may see more.

However, it is true that this space has changed significantly on the mini and Pro Max, and both feel that the screen has a lot of room.

Performance battery life

iPhone 13 is equipped with the A15 bionic chip, and the measured CPU and GPU performance have been slightly improved.

The highest image quality of the game test can guarantee the smooth operation of the full frame rate at the beginning, and the frame rate of the mobile phone will drop to 40 frames in about five minutes.

After half an hour, the top of the front and rear of the phone reached 42.1 degrees, and the border was a little hot.

But in low-power mode, iPhone 13 becomes another face, with the highest image quality average frame rate of 59.3 frames, and the experience is very smooth.

After half an hour, the highest temperature before and after the phone was around 41 degrees. Sure enough, you still need to turn on the power saving mode to play games.

After three hours of battery life test, iPhone 13 mini power failure 46%, compared to 12 mini 74% results, has made great progress, but as the main machine used Remember to bring a power bank when you go out. .

iPhone 13 test power down 34%, compared to the iPhone 12 47% also improved significantly, adhere to the day moderate use of basic no problem. It can be seen that this generation of A15 for power control is very good.

As for charging, iPhone 13 half hour charge 50%, 108 minutes full charge, iPhone 13 mini half hour charge 61%, one and a half hours full charge, The speed is basically the same as the previous generation .

Unlike previous years, this year’s A15 Bionic has been customized for different models. iPhone 13 Pro series has one more GPU core than iPhone 13, and the GPU performance has been improved by 32%, so that it has enough performance to support ProMotion, ProRes and Pro-level cameras.

In fact, the performance of the A-series chips every year has never been worried. The actual daily use is very smooth, and there may be no difference in experience even in the next three to five years. This is also the strength of the A-series chips. As for the performance improvement every year, it is more for the support of imaging functions.

camera

iPhone 13 directly used the large-size sensor of last year’s iPhone12 Pro Max, and the ultra-wide-angle lens also improved the sensor speed. The only constant is the ancestral 12 million pixels. But Apple has never relied on hardware to take pictures, and this time is no exception. A15 Bionic chipLet iPhone 13’s computational photography have a better experience.

Let’s take a look at everyone’s favorite portrait mode. In the same environment, the main body of the iPhone 13 is obviously brighter, the skin tone is more transparent, and the edge processing of the characters is better than the overall appearance.

In the case of sufficient daylight, the main camera of iPhone 13 has a very stable performance, whether it is analytical power or color performance, it is the current first-class level, and the style is still true restoration. But compared to iPhone 12, there is no very obvious difference.

Only in some complex scenes, the color of iPhone 13 is more accurate.

As for the ultra-wide-angle performance, there is basically no difference, from the center to the edge has a good image quality performance, but there is still some room for improvement.

At night, the photos of iPhone 13 are purer, and the bright part also ensures sufficient exposure, which is significantly improved compared to iPhone 12.

In the urban environment, iPhone 13 also has a better dark performance, and the sense of hierarchy of the picture is stronger. Compared with the blind pursuit of shooting bright at night, iPhone 13 returns black to the night, and the photo will have a strong sense of atmosphere.

As for ultra-wide angle, iPhone 13 is also better for dark parts, but in some scenarios there will be excessive white balance adjustment.

Large size sensor and A15 bionic chip also brought significant improvement to the iPhone 13 video, in different scenes iPhone 13 has more accurate color and better image quality, performance is as good as ever.

Especially at night, the advantage of iPhone 13 is obvious, it can only be said that in the aspect of mobile video shooting, only iPhone can beat iPhone.

This time, Apple also brought a movie effect mode. This function is simply that the mobile phone will Recognize the face of the person in the screen as the focus It automatically understands the relationship between characters, and when the characters make corresponding actions, the focus will automatically shift, or you can manually control the focus.

From the experience point of view, the completion of this function is very high, and the mobile phone is very important for The judgment of depth of field blur is very accurate Switching between focuses is very smooth. The final piece retains all depth of field information and can be refocused during post-editing.

The entire process is realized through algorithms, which seem simple but are computationally intensive, so much so that the Pro series can only shoot 1080P, 30 frames of video.

In short, the A15 bionic chip brings a very stable image performance to the iPhone 13, making it easier for the mobile phone to take good photos. At the same time, the addition of functions such as photography style and film effect mode also provides more possibilities for most people to create.

Buying suggestion

In fact, different from last year’s iPhone 12 and 12 Pro, this year iPhone 13’s two lines gradually opened the gap, Pro series has ProMotion, ProRes and a set of very Pro cameras, naturally more focused on people with professional creative needs, so we think iPhone 13 is still suitable for the vast majority of people, after all, it is also a flagship experience in screen quality, performance and camera table, daily use is completely the same. Plus this year’s Apple wave Volume reduction The operation makes it fully cost-effective.

If you use the model before iPhone 12, there is no particularly large demand for mobile phone photography, only a flagship with good overall performance, then iPhone 13 should be your best choice to enter the 5G era, of course, it is also your first choice to embrace iOS.

The above is the entire content of this video. With a hard-core attitude, we will do a material review. Here is the review of the Phoenix family. There are a group of professional, interesting and serious friends waiting for you.

The "618" shopping festival has started, and the home of online shoppers like Xiao Cui may be "full of boxes" in these days.

　　June 17-23 is this year’s National Energy Conservation Publicity Week. According to a survey by Beijing Evening News reporters, in addition to gifts, over-packaging has become a common phenomenon in the fields of instant consumption for personal use, such as take-away meals, fruits and vegetables, drinks and express delivery. Experts said that packaging reduction requires the government, industry associations and platforms to do their part.

　　Takeaway: The lunch box for two people can be stacked 20 cm high.

　　"If you’ve eaten the takeout of noodles from Hefu, you’ll know that the packaging is simply grandiose." Xiao Yang’s company is located in Chaoyang District. Sometimes she eats out at noon and sometimes orders take-out. Among them, the take-out of noodles from Hefu impressed her deeply: "A big insulation bag, a plastic bowl of noodles, a plastic bowl of soup and a plastic box of snacks, and tableware are also printed separately ‘ Four Treasures of the Study ’ In the plastic packaging. "

　　Xiao Yang admits that such exquisite packaging makes the meal look "tall", and it does make the dining experience better: "The soup and noodles are packaged separately, and then mixed when eating, so that the noodles will not be smashed, but there are still some flashy places, such as insulation bags, which often do not play a fixed role, and will still be sprinkled. Moreover, although the insulation bags are not disposable, they are actually difficult to reuse and are finally thrown away. There is also some waste in the details, like half a sausage is also placed in a long plastic box. "

　　Jamlom, a freelancer, feels the same way about this. He often orders the take-out of Manling porridge shop at home: "When one porridge is delivered with two steamed or fried things, even if two steamed dumplings can be packed in one carton, the merchant must separate two boxes. If two people eat it together, the cardboard box will stack up 20 cm when throwing garbage at last."

　　Jamlom guessed that it may be more convenient for merchants to confirm whether they have enough weight, and the cost of dining boxes has replaced the labor cost, but this is obviously a waste of natural resources: "The paper box is too small to reuse other things, not to mention how many times it is clearly indicated that tableware is not needed, and merchants still send a bunch of disposable tableware."

　　The Beijing Evening News reporter found that in the comment areas of the above two businesses, exquisite packaging is a frequent label on the take-away platforms such as Hungry, Meituan, etc. Most customers have a positive attitude towards this, and only when there are obvious problems with the food will they question the packaging as "flashy".

　　Fruits and vegetables: Each banana is wrapped separately.

　　"A year ago, I was often in ‘ Tiantian Orchard ’ When you buy fruit on the App, its packaging is very excessive. Every kind of fruit you buy has a box, and there is a big cardboard box outside. It is very exquisite, but I really don’t think it is necessary. After all, the wool is on the sheep. " Ms. Zeng is the HR Commissioner of an enterprise. She told the Beijing Evening News reporter that any fruit purchased on this App is a carton of one kind. She made a special suggestion to the customer service. "I said that this packaging method is not environmentally friendly enough, and it is recommended to reuse it. The general meaning of the customer service reply is that this packaging is to protect the quality of the fruit, but I didn’t adopt my opinion anyway."

　　The reporter spent 69.8 yuan on the App to buy kiwi fruit and bananas. After the arrival, it was found that the packaging was indeed excessive: six kiwi fruits and six imported bananas used a 35×26×24 cm carton, a 31×28×8 cm carton, a 26×18×9 cm carton and 14 air bags.

　　"The daily fresh packaging is also a bit too much. Every time you buy something and throw two packages, the trash can at home will be full." Ms. Sun, who works in the procuratorate, told the reporter that she often buys vegetables and some frozen products. Vegetables are always in a plastic box, and the bubble bags used for packaging frozen products also take up a lot of space. "In fact, the delivery distance is very short, and most vegetables are not afraid of bumping. I don’t think it is necessary to have a plastic box for each."

　　Mr. Kang, who lives in beiyuan road, said that there is a similar situation in the freshness of physical stores: "Litchi, strawberries, tomatoes and apples in the fresh supermarket near my home can be sold in bulk, so we must wrap them in transparent plastic boxes."

　　Coffee: It’s a pity to throw it away in a grand way.

　　"Even the box of coffee is really beautiful and strong, and I can’t bear to throw it away when I send it." Xiao Chang is the product manager of an Internet company in Zhongguancun. For her, coffee is the best companion for overtime work, so she knows a lot about the take-away packaging of coffee shops around the company.

　　Even the packaging of coffee, including a paper bag, a paper box with aluminum foil inside and a cardboard buckle with spill prevention inside, "in fact, it can’t be completely over-packaged, but it is very strong, with good insulation and spill prevention effects. At first, it will be reserved for things, but because it is too frequent to drink, there is not much room for it in the office, and then it is a pity to throw it away directly." Xiao Chang said.

　　COSTA coffee has also received a lot of spit on social media because of almost the same packaging. Netizen @M Positive suggested in Weibo on May 11th: "I just ordered a mocha, so the packaging is too grand. It’s not that I don’t like it, but that the current take-away packaging is too wasteful. Over-packaging is really not environmentally friendly and wasteful. It would be better if there were simpler packaging. "

　　Beijing Evening News reporter ordered a latte takeaway of COSTA Coffee (Fenghui Times Store) near Financial Street on June 13th. After receiving it, he found that the packaging was simple paper bag and spill-proof cardboard buckle, which saved the paper box. After consulting customer service, the reporter learned that the store was simplifying the packaging recently.

　　"Look at the size of this packaging carton, which is close to 40 cm long and 30 cm high. There is a small cup with a height of 7 cm inside, and there are all loose air bags next to it." Xiao Cui, a white-collar worker, was quite frightened when she received the courier from Zara Home. "In fact, the box is easy to break when it is big, and the small box has small movable space, so it is not fragile. I don’t know what the merchants think."

　　Platform: Encourage environmental protection and reduced packaging.

　　The Beijing Evening News reporter contacted Meituan and Hungry for the problem of take-away meals and over-packaging of fruits.

　　The person in charge of Meituan’s public relations told the reporter that Meituan’s takeaway will push the environmental protection initiative letter in the background of the business and advocate moderate packaging; Time nodes related to environmental protection will also be advocated in public places, such as moderately packaged public service advertisements placed on subway buses last year; The US Mission Qingshan Partner Program is also recruiting merchants and packaging partners to jointly research and develop and pilot packaging reduction. For example, the pizza packaging jointly developed with Challenger Pizza and Debai Packaging Laboratory has reduced paper use by 50%.

　　Hungry means that for the existing platform merchants, on the basis of business qualification, food safety and other basic requirements, higher requirements are put forward for the take-away packaging, food delivery bags, disposable tableware and tableware packaging and back-end processing of "Blue Planet Merchants". This year, research and development of alternative and transitional plastic-reducing materials will be carried out for a certain category of packaging on the platform.

　　"Overpackaging is a rare situation, and only high-end businesses will do it. After all, the cost of packaging is also a problem to be considered. The average unit price of takeaway customers is only 20 to 30 yuan, and most businesses will not work too hard on packaging." An industry insider who asked not to be named told reporters that the relationship between the platform and the merchants is not management and managed, but cooperation, which determines that the platform can’t control the over-packaging behavior of the merchants: "In order to be beautiful and make consumers feel high-end, they work hard on packaging, and even over-package. The platform and the merchants are independent legal persons, and the platform can’t stop it. It can only be said that they are recommended to use environmentally friendly materials."

　　Expert: all parties should do their part to reduce packaging.

　　"When it comes to over-packaging, the first thing that comes to mind is moon cakes and gift boxes. Now this over-packaging has actually decreased. On the other hand, with the great development of express delivery, take-away and other industries, the frequency of packaging in these industries is getting higher and higher, and some businesses will over-package in order to look high-end, and a large amount of packaging waste will be generated every day." Qiu Jizhong, Deputy Secretary-General of Beijing Design Society, told reporters at the launch day of Beijing Energy Conservation Publicity Week in 2019 and the release conference of the first green packaging design solicitation activity.

　　Li Jinghua, president of Beijing Packaging Technology Association, said that there are indeed some merchants who lack the awareness of saving materials, but from another perspective, take-away, express delivery and fresh packaging are the first to protect goods. It is impossible to ask merchants to ignore the protection of goods in order to save materials. "This requires more efforts in packaging material selection and structural design to prevent merchants from having to use excessive packaging to protect goods."

　　Qiu Jizhong introduced that some problems of over-packaging can indeed be solved by optimizing the design. "For example, a carton with an internal Z-shaped structure was collected this time, and the use of packaging paper and fillers was reduced through structural changes."

　　Qiu Jizhong introduced that environmental protection standards for packaging in different sub-sectors have been formulated. After the introduction of the standards, there will be a clear definition of what belongs to environmental protection packaging and what belongs to over-packaging, which will guide platforms and businesses.

　　"The government should promote the formulation of relevant standards, laws and regulations, industry associations should help implement and help the landing, and the platform should participate in advocating packaging reduction, doing its best and doing its part." Li Jinghua said.

　　Our reporter Bai Gewen took a picture of Gaoxia.

For the early adopters with a young mentality, what is the greatest experience that a car can bring? It is not the smart configuration full of gimmicks, or the colorful and fashionable appearance, but the ability to really control it and let it go off-road. ICAR 03, with its original super-strong chassis, is like a "small steel gun on the road", which brings outstanding road handling performance, fast straights and sharp corners, and outdoor off-road can also provide an extraordinary electric four-wheel drive refreshing experience. It can be said that it is full of surprises and full of players in all road conditions.

The chassis is more stable, detours do not float, and mountain roads do not sway.

A car is not for looking at. Only when you drive it can you really feel its texture. The stability of the chassis depends on the performance of the suspension. iCAR 03 adopts the only original super-strong chassis of the same class, adopts a 3,500-ton integrated die-casting tower top structure, and has an all-aluminum honeycomb structure girder, which has higher cavity strength than ordinary steel plates, and can effectively resist side impact, with both structural strength of non-loaded body and comfort of loaded body, giving consideration to light weight and energy consumption performance.

More accurate control, perfect combination of performance and comfort.

When it comes to control, many people think that this is the world of fuel vehicles. With the participation of Prodif’s Asia-Pacific top team, which has been focusing on vehicle power system development and vehicle handling performance development for more than 30 years, the track chassis adjustment experience in F1, WRC, Le Mans and Dakar Rally was applied to iCAR 03, giving iCAR 03 excellent track genes, achieving better handling performance and bringing a real track-level driving experience. In addition, the number of turns on the steering wheel is reduced from 3 to 2.6, which also creates a sharp sense of direction when iCAR 03 turns.

While improving the handling performance, iCAR 03 has also been optimized in terms of comfort. The chassis structure of H-arm multi-link and hydraulic bushing is adopted, and the H-arm is made of hollow cast aluminum, which reduces the weight by 30%, reduces the unsprung impact, is light and high-strength, and greatly improves the comfort of bumpy road sections. In addition, the control arm bushing adopts hydraulic bushing technology, which can reduce the road vibration by more than 30% under bumpy road conditions, and adopts oversized suspension cushion to isolate the vibration of the motor more efficiently.

Lightweight, bringing firm and sensitive driving pleasure.

For a pure electric SUV, the length of the same cruising range is directly related to the weight of the whole vehicle, while the lightweight technology of iCAR 03 achieves the perfect balance between cruising range and vehicle weight, and at the same time, it also brings more sensitive and lighter handling. It adopts an original all-aluminum multi-cavity cage body, a luxury car-class all-aluminum body, and naturally comes with a regenerative anti-corrosion layer, which will never rust during its life cycle, reducing the weight by more than 30% compared with the traditional steel body, but improving the stiffness by 30%; While achieving the perfect unity of firmness and lightness, it also brings a large thrust-to-weight ratio, a lighter start, a more direct dynamic response and a more handy control, which has become the ultimate pursuit of off-road control.

Excellent chassis support makes iCAR 03 have a solid sense of road, clear response and strong passability, while professional and super-strong chassis technology can make you easily deal with all kinds of complex roads, bring you full control confidence and security, and satisfy your all-weather passion. Since the pre-sale, it has been popular among early adopters with young mentality. If you also want to be a galloper, then the "bottom" iCAR 03 must be your best choice.

Huang Lei, the name once represented the image of a "literary youth". His acting, directing, singing and teaching are admirable, and so is his marriage and family. However, in recent years, this actor who once claimed to be a "good man" has been frequently exposed to emotional problems and behavioral disputes, which has aroused widespread concern. Recently, his sex scenes in movies caused controversy, because his figure and belly became the focus. Some netizens even broke the news that he had an affair with his female college students, proper relationship, and made moves on beautiful women in public. These events make people question his professional attitude and the management of his own image, and also make his "literary" personnel completely collapse.

Huang Lei was born in a family of performers in Jiangxi province, and his parents were local drama actors. He was influenced by drama since he was a child. However, although his family background laid the foundation for his performance, he himself did not have a strong interest in performance from the beginning. An experience in his childhood made him feel resistant to acting, which may be one of the reasons why he explored in the field of acting in the future.

Huang Lei didn’t do well in the college entrance examination, so he couldn’t enter an ideal university. However, he followed his parents’ advice and applied for the Shanghai Theatre Academy. However, after failing in the first year, he decided to change his strategy and go to Beijing Film Academy. There, he was lucky enough to be discovered by Chen Kaige, and this opportunity changed his life path. Chen Kaige’s vision enabled Huang Lei to enter the entertainment circle. Although it did not immediately become popular all over the world, it marked a good start for his career.

Huang Lei’s love life has always attracted much attention. Before marriage, it was revealed that he had had a speculative friendship with Rene Liu. This relationship did not develop rapidly, and it was not until they co-filmed the TV series April Day on Earth that their feelings changed clearly. However, his love life is not limited to this period. Yi Nengjing showed unusual behavior towards Huang Lei during filming, which made people doubt her motives. This incident triggered a lot of speculation about Huang Lei’s emotional concept.

Huang Lei married Sun Li on March 8, 2004. Sun Li met Huang Lei at the Beijing Film Academy, when Huang Lei was her teaching assistant and fell in love with her at first sight. After nine years of long-distance running in love, they finally got married. It must be said that Huang Lei and Sun Li have always been the "immortal couple" that everyone envied.

The married life of Huang Lei and Sun Li has also attracted much attention. They have a daughter, Huang Duoduo, which is the highlight of "Where is Dad?". However, although Huang Lei showed his image as a "good father" in the program, some people pointed out that there were hidden problems in his words and deeds. He is often accused of controlling and suppressing his wife Sun Li with words, which makes people worry whether he really understands what equality and respect are. Huang Lei also showed "great wisdom in wife training" in variety shows, and made the internal problems of the family public. This practice caused many questions, and people began to question whether he was only thinking about his public image, regardless of the feelings of his wife and daughter.

In recent years, the public image of Huang Lei has gradually collapsed. He frequently reveals his true character in variety shows instead of covering it up. The quality of his works has also been questioned, and many characters have striking similarities with his own personality, which makes the audience feel bored and disappointed. Recently, his sex scene in the movie Dying to Survive caused controversy, because his figure and belly became the focus. This incident makes people question his professional attitude and the management of his own image.

Some netizens broke the news that Huang Lei once had an affair with her female college students, and made moves on beautiful women in public. An insider claimed that he was a student in Huang Lei, and provided evidence to prove that the accusation was true. He also said that there was conclusive evidence that Huang Lei had a relationship with female college students. What’s more, it was a long time ago. Now that the female college student has graduated, married and had children, Huang Lei no longer hides herself as she gets older, and negative news keeps coming.

The impact of these events on Huang Lei is enormous. He not only lost the support and trust of many fans and audiences, but also completely collapsed his "literary" personnel. He once thought that he could use the cloak of "literature and art" to cover up his "greasy" heart, but it turns out that this is just a self-deception When the truth is revealed, he can only face his own mistakes and consequences.

Huang Lei also didn’t get sympathy and support from peers and insiders. On the contrary, many people expressed their dissatisfaction and contempt for him. For example, Chen Kaige once said in an interview: "I think Huang Lei is a good actor, but I don’t like him as a director." This sentence shows that Chen Kaige is not satisfied with the works directed by Huang Lei. Rene Liu once insinuated Huang Lei’s disloyalty and irresponsibility in Weibo. She said, "I don’t know about you, but I think that if a person can’t be responsible for his family and marriage, he is not qualified to be responsible for anything." This sentence shows that Rene Liu does not understand and forgive Huang Lei’s emotional problems. Yi Nengjing once expressed dissatisfaction and ridicule to Huang Lei in the program. She said, "You know, you are one of the men I hate most." This sentence shows the change of Yi Nengjing’s attitude and feelings towards Huang Lei. These people were Huang Lei’s former partners and friends, but now they have drawn a clear line with him and even openly expressed their opposition and boycott.

These incidents have done serious damage to Huang Lei’s career and reputation. He not only lost the support and trust of many fans and audiences, but also completely collapsed his "literary" personnel. He once thought that he could use the cloak of "literature and art" to cover up his "greasy" heart, but it turns out that this is just a self-deception When the truth is revealed, he can only face his own mistakes and consequences.

These incidents also had a great impact on Huang Lei’s family and marriage. He not only betrayed his wife Sun Li, but also hurt his daughter Huang Duoduo. He not only destroyed his family happiness, but also ruined his father image. He not only plunged himself into a moral crisis, but also lost his dignity and credit. He not only brought himself trouble and predicament, but also brought himself shame and regret.

Editor in charge:

　　 On May 3 this year, Chang ‘e VI was launched from Wenchang Space Launch Site in China, and was sent into the earth-moon transfer orbit by Long March 5. In 53 days, Chang ‘e-6 successfully landed in the pre-selected landing area of aitken Basin in the South Pole of Moon Back, and achieved the world’s first sampling and take-off of Moon Back, and successfully returned to Earth with lunar soil on June 25th, with a round trip of more than 760,000 kilometers.

　　Behind this success, there are many unknown stories. A series of reports on the science and technology "Chang ‘e" on the Moon explores the scientific and technological forces behind Chang ‘e’s lunar exploration. Today we pay attention to the five-star red flag displayed on the back of the moon for the first time.

　　"Stone Edition" Five-Star Red Flag is made of basalt.

　　The national flag displayed on the back of the moon on Chang ‘e VI has very special requirements for materials. It is made of "stone".

　　In a quarry in Yuxian County, Hebei Province, a kind of stone called basalt is being collected here. The basalt here is one of the oldest, largest and most complete basalt groups in China.

　　Zhu Zhaochun, Head of Xinyuan Basalt Mining in Yuxian County:Basalt hasHigh toughness, corrosion resistance, acid and alkali resistance, high temperature and low temperature resistance.Excellent performance.

　　Zhu Zhaochun knows a lot about the characteristics of basalt, but what he doesn’t know is that,These characteristics of basalt are the materials suitable for the lunar environment that the Chang ‘e-6 lunar flag development team has been looking for.

　　Wang Yunli, a professor at wuhan textile University, a member of the Chang ‘e-6 lunar flag development team:In the environment of the moon, its high and low temperatures are as high as MINUS 150℃ and above zero 150℃. Because the moon has no atmospheric protection, ultraviolet rays will directly shine on objects. Therefore, for the national flag, it puts forward more stringent environmental requirements.

　　In addition to the characteristics that can meet the lunar environment, the research team also found that basalt is similar to the lunar soil in chemical composition.

　　Cao Genyang, a professor at wuhan textile University, a member of the Chang ‘e-6 lunar flag development team:We found that the composition of basalt on the moon is very complicated through the published literature on lunar soil, with 10 to 20 components, the most important of which is silica. We matched and analyzed the stone and found that its data was very close to the composition of the lunar soil. Finally, we chose the basalt mine in Yuxian County, Hebei Province.

　　In this way, the basalt in Yuxian County, Hebei Province was selected as the raw material for making the Chang ‘e VI national flag. These stones, which have existed on the earth for hundreds of millions of years, have embarked on the road to the moon.

　　Tempered stones become ultra-light and ultra-thin fabrics.

　　There is a very important reason why Chang ‘e VI chose the "stone version" national flag to show the back of the moon.Making national flag from basalt is an exploration of in-situ manufacturing of lunar surface..In the future, it is necessary to use local materials to build a lunar base, and to make basalt on the moon into sheet or tubular building materials for lunar surface construction, which will greatly save costs than using materials on the earth.

　　After the raw materials are determined, how to turn stones into cloth and accurately control the weight?It has become a difficult problem that the development team urgently needs to overcome.

　　The national flag on the lunar surface of Chang ‘e VI has the same specifications as the national flag on Chang ‘e V, and its size is 300mm×200mm, which is almost the size of a piece of A4 paper. However, the density of basalt fiber is nearly twice that of Chang ‘e V national flag, which will lead to the heavier "stone version" national flag. Because it will be used in spacecraft, the weight requirement of the national flag on the moon surface is extremely demanding, and it needs to keep the same weight under the same size. The developer calculated that this requires the density of basalt fiber to be 8.8 grams per 1000 meters so as not to be overweight, but how can such fine basalt fiber be produced?

　　Cao Genyang told reporters that the process control, furnace temperature, spinneret state and so on were constantly being debugged, but no matter how to do it, the density index of 10 grams per kilometer became an insurmountable gap in making basalt fibers. After numerous experiments, it is found in a production process that the trapezoidal optimization of the inner cavity structure of the spinneret and the distributed accurate temperature control in the furnace can solve the problem of insufficient characteristics of basalt fibers.

　　In the end, the development team successfully realized the stable mass production of superfine basalt fiber. The weight of the Chang ‘e VI flag they made was only 11.3 grams, which was 0.5 grams lighter than that of the Chang ‘e V flag.

　　Four years of tackling key problems on the back of the moon perfectly presents "China Red"

　　Ultra-fine basalt fiber has been made, and the next challenge comes one after another. "How to color the fiber made of stone" has become another difficult problem for the development team.

　　Different from cloth, the filaments drawn from stone have a particularly smooth surface, and the pigment cannot be firmly attached to the flag surface. The flag is finished, and the color can’t go up. The research team can only try again and again to find a solution.

　　Finally, based on the experience of Chang ‘e V, the research team used the aramid short fiber hairiness on the surface of the fabric to make the binder in the pigment form a similar "rivet" anchoring effect with it, effectively improving the bonding fastness of the paint interface and the color fullness of the national flag pattern, and ensuring the lunar display effect of the national flag.

　　Researchers told reporters,From a silk to a flag, there are at least forty or fifty steps in the middle process.Compared with the eight-year research on the development of Chang ‘e-5 national flag, the research time of Chang ‘e-6 national flag is particularly tight, and the team members have almost no rest days, all of which are to ensure that this national flag can withstand the "tempering".

　　Dr. Sheng Dan, Ph.D., wuhan textile University, member of the Chang ‘e-6 lunar flag development team:There are four mechanical experiments, and there are three steps in environmental experiments, including pre-test and so on, at least 50 steps. Finally, I took a flag and went through a complete experiment from beginning to end, including the final deployment. Later, when I saw the national flag organization unfolding, I felt very cute and proud when I saw the organization unfolding.

　　The lunar flag development team lasted for nearly 4 years and conquered it.Spinning, Weaving and Color Construction of Basalt MicrofiberAnd many other international problems, the "stone version" of high-quality fabric national flag without temperature control protection and independent dynamic display was developed for the first time, which realized the first independent dynamic display of the national flag on the back of the moon in China. Put the "China logo" on the moon again!

　　Prospects can be expected. Aerospace science and technology will weave "fire-proof magic clothes"

　　While the "stone version" of the national flag was being developed,The lunar flag team started the application research of basalt fiber in the fields of heat resistance and flame retardant.. These research results also make basalt more useful.

　　Natural fibers with golden brown luster are drawn from hard basalt. In the production workshop, a large number of basalt crushed stones are thrown into the blast furnace. At the high temperature of 1500℃, the rocks are melted into liquid, and then drawn into filaments that are almost invisible to the naked eye through the rotating shaft. And this fiber contains a total of 400 monofilaments of 500 microns. Touching a single filament of basalt fiber with your hand makes it feel like a hair filament, silky and extremely tough.Clothes made from them are "magic clothes" with fire-proof function..

　　The cloth made of basalt fiber combined with textile processing can be used as fire clothes in special scenes, and can also be made into household items such as fire curtains and fire mattresses in the future. At the same time, basalt fiber has broad application prospects in road construction, composite materials, new energy vehicles and other fields.

　　Wu Minyong, General Manager of Hubei Huierjie New Materials Technology Co., Ltd.:In the field of new energy vehicles, it can be used as a brake pad and a fireproof cloth for battery modules; In the field of aerospace military industry, we use it as an interception network for space launch sites.

　　Xinhua News Agency, Beijing, December 29th　Question: Help? An accomplice! -Behind the case of electric fraud, beware of the trap of "helping the letter"

　　Xinhua News Agency reporter Lu Chang

　　At present, all kinds of telecommunication network fraud show the characteristics of complete chain and clear division of labor, which increases the confusion of fraud and the difficulty of preventing and cracking down. Among them, some people engage in false account registration, mobile phone and bank card opening, buying and selling or providing "services" such as "receiving codes" and "running points", some knowingly commit crimes, some covet small profits, and finally embark on the road of illegality or even crime. Since the beginning of this year, according to the deployment of the "Net Net 2021" special action of the Ministry of Public Security, Beijing police have cracked many cases suspected of helping information network criminal activities (hereinafter referred to as "helping the letter crime"). The reporter will take you to understand what "helping the letter crime" is and how to avoid falling into the trap.

　　Three types of "letter-helping" activities are on the rise.

　　According to the data of the main cases handled by the national procuratorial organs from January to September recently released by the Supreme People’s Procuratorate, the crime of helping the letter ranked fourth, with a total of 79,307 people, up 21.3 times year-on-year. Legal experts pointed out that this aspect reflects that telecommunication network fraud is still very rampant in the emerging stage; On the other hand, while cracking down on illegal crimes of telecommunication network fraud, the judicial organs have strengthened the crackdown on the related crime of helping the letter. With the investment of a large number of judicial resources, the number of public prosecutions of the crime of helping the letter has also increased significantly.

　　The full name of "helping the letter crime" is "helping the information network criminal activities", which is an additional crime in the criminal law based on the traditional theory of joint crime. The reporter combed the cases cracked by the Beijing police and found that the current three types of illegal crimes suspected of "helping the letter" are outstanding.

　　-helping overseas fraud gangs "run points" to launder money. From April to early September this year, the criminal suspect Chang hired many people to use overseas social software to receive the money transfer task list of upstream criminal suspects in a house in Shijingshan. After receiving the order, the gang members used two platforms with servers located overseas to transfer the stolen money to the next bank card, and the daily "running points" amounted to several million yuan. According to the introduction of Shijingshan Public Security Bureau, when the gang was destroyed, it was found that the gang had specially prepared a generator to prevent the unexpected power outage in the hidden dens from affecting the order. The gang members have been criminally detained according to law.

　　—— Illegally obtaining and providing batch social media accounts and "unsealing" banned accounts for fraud gangs. Among the gangs suspected of "helping the letter" destroyed by Haidian Public Security Bureau, many suspects have registered a dating App account in batches through illegal technical means since October last year, and sold it to overseas fraud gangs to implement "killing pig plates" fraud, with a total profit of more than 1.4 million yuan; In another case, criminal gangs provided the service of "unsealing" the social media accounts involved in the case and sending fraudulent information emails in groups. In various ways, they enabled downstream fraudsters to use the same number to commit crimes multiple times. Statistics show that the above two cases are related to more than 700 cases of electric fraud nationwide, involving a total amount of 53.2 million yuan.

　　-Provide "service" for sending and receiving SMS verification codes. In a case of criminal activities suspected of helping information network uncovered by Miyun Public Security Bureau, the suspect Wang took advantage of his position to purchase more than 2,000 real-name telephone cards from construction sites and other recruitment units at the price of one in 30 yuan all over the country, providing others with illegal acts of receiving verification codes. According to the reporter’s understanding, through "receiving code", a large number of social App accounts can be registered in a short time, and power supply fraud gangs can be used for scams such as "killing pig plates".

　　Some people are cheated for small profits, while others knowingly commit crimes.

　　The reporter learned that some lawless elements used profits as bait to induce some people to open cards, or claimed to handle bank cards and corporate accounts at high prices. Some people were greedy for "into the pit" for small profits, and after the criminals were arrested for "helping the letter", they also entered the disciplinary list.

　　Zhang Na (pseudonym), 25 years old, was told by the company that the bank card he provided as a salary card was frozen when he went through the entry formalities. According to Zhang Na’s memory, this card was tricked into "acting as an agent" when she was in college. At that time, a total of five cards were opened, and she got 300 yuan money herself. Judging from the bank flow they collected, the transaction funds of these bank cards were transferred away on the same day after entering. An experienced anti-fraud policeman told reporters that this situation was obviously used for telecommunication network fraud and became a "tool person". "Freezing the bank card is not the main problem. She is likely to be included in the disciplinary list, which will have a great impact on her life." The policeman said.

　　In the interview, the reporter found that some gangs used the qualification of value-added telecommunications services to "sell dog meat by hanging sheep’s heads" and engaged in electric fraud activities with their landline numbers. In the case detected by Haidian Public Security Bureau, a company connected lines and contracted more than 20,000 landline numbers on the grounds of setting up a call center. However, the company used the obtained landline number to sublet for profit, and did not stop the illegal behavior after the relevant units repeatedly warned. On November 10 this year, the police carried out the network-closing operation, and arrested 13 suspects including the legal representative of the company, Wang Moumou, and initially verified that the company’s landline number involved more than 200 telecom network fraud cases nationwide.

　　Strengthen warning propaganda and continue to strike accurately.

　　The public security police and legal practitioners interviewed believe that it is necessary to further strengthen the propaganda on typical cases of "helping the letter", profoundly reveal the harm of telecommunication network fraud, strengthen warning education, especially for school students and labor-intensive employment enterprises, improve the people’s awareness and ability to prevent telecommunication network fraud, and build a solid barrier to prevent and crack down on telecommunication network fraud.

　　In addition, the reporter combed a number of public judgment documents and found that the crime of "helping the letter" takes the unemployed as the main criminal group in the defendant’s occupation. These defendants received "card receiving" advertisements posted by social platforms or friends, and used their personal information to handle bank cards at prices ranging from 200 yuan to 2,000 yuan, and then sold them to others, who used them for telecommunication network fraud. Therefore, the Internet social platform needs to establish a security compliance system and a closed-loop risk management system for evaluation, prevention, audit and discovery, and governance, so as to provide early warning and pre-disposal of all kinds of illegal information at the first time.

　　Respondents said that the illegal operation of "two cards" has a very serious impact on the occurrence of telecommunication network fraud cases, and it is necessary to further promote the "broken card" action to curb the high incidence of telecommunication network fraud cases. At the same time, we will severely punish a number of institutions and industries with outstanding problems involved in the case, focusing on strengthening law enforcement inspection and urging rectification.
