Glass curtain walls of urban high-rise buildings become the source of ＂light pollution＂ (Figure)

　　Recently, some readers reported to this newspaper that some glass curtain walls of the World Financial Center reflect strong light. Not long ago, the planned Shanghai Tower, the tallest building in China, published an environmental assessment report online, in which "the influence of reflected light from glass curtain wall" attracted people’s attention.

　　The glass curtain wall causes strong light reflection and causes light pollution, which has become a problem that cannot be ignored in urban development. Is it a light and beautiful building material "angel" or a "devil" that causes light pollution?

　　The reporter recently visited the main argumentation and examination and approval department of "light reflection influence".

　　The inner ring line was once banned, but the effect was not obvious.

　　In the Building Energy Conservation Section of the Shanghai Construction Industry Management Office and the Office of the Science and Technology Committee of the Shanghai Municipal Construction and Transportation Commission, two responsible persons mentioned one thing in unison-in 1999, the Standing Committee of the Municipal People’s Congress promulgated the Regulations on the Management of Construction Engineering Materials in Shanghai, which stipulated that the Municipal Commission for the Establishment of Diplomatic Relations should compile a "prohibited and restricted catalogue" and publish it after approval by the municipal government.

　　In 2000, the first batch of "Prohibited and Restricted Catalogue" was published, and the glass curtain wall was among them. At that time, it was clearly stipulated: "It is forbidden to design and use glass curtain walls within the inner ring road, except for the podium of the building; Between the inner ring line and the outer ring line, the area of glass curtain wall shall not exceed 40% of the construction area of the outer wall. Construction projects using glass curtain walls should be implemented after environmental assessment by the environmental protection management department and approval by the planning and construction management departments. "

　　However, the development of glass curtain wall has not stopped because of the publication of the catalogue. Wu En, deputy director of the Office of the Science and Technology Committee of the Municipal Commission for the Establishment of Diplomatic Relations, explained: "Before the publication of the catalogue, many construction projects have passed the examination and approval. This legitimate reason makes these projects exempt from the catalogue."

　　At present, there are many glass curtain wall buildings on both sides of the road, many of which were built after 2001 and are within the inner ring. It is forbidden to stop, ostensibly because of the "time difference" of project approval, but in fact it has a compelling reason.

　　What materials can be used for high-rise buildings without glass curtain walls?

　　An expert from Shanghai Environmental Monitoring Center, who asked not to be named, believes that the widespread use of glass curtain walls is mainly aimed at the "helpless actions" of the city’s super high-rise buildings. This expert has participated in the examination and approval of many important construction projects in the city. She said that although the regulations on restrictions on the use of glass curtain walls have been issued for many years, it is "unrealistic" to completely ban them. Mr. Shen, the head of the Building Energy Conservation Section of the Shanghai Construction Industry Management Office, said: "The’ one size fits all’ approach is not appropriate."

　　"The glass curtain wall is really necessary, and some of its advantages are irreplaceable by other building materials." Wu En explained that especially for super-high-rise buildings with more than forty or fifty stories, the load-bearing requirements for the foundation are relatively high. Under the same circumstances, light glass curtain walls have to be used as the external wall. "If a building with a height of one or two hundred meters does not use glass curtain walls, what better materials can it use?"

　　In addition to being light, the glass curtain wall also has the advantages of beauty, earthquake resistance, high permeability and rapid construction. Since the early 1970s, Shanghai has tried to integrate it into urban architecture for the first time. It has been more than 30 years since then, and its technology has passed the standard and its safety factor is high, which naturally makes it the first choice for many architects and developers.

　　Light pollution is difficult to avoid, but it must be strictly controlled.

　　Glass curtain wall is sometimes a "double-edged sword". On the one hand, glass can be recycled, which makes it stand out from many light materials such as aluminum; On the other hand, strong light reflection causes pollution, which attracts more and more attention.

　　"Admit its necessity, and we can’t ignore the negative effects." Wu En introduced that the municipal environmental protection department has issued regulations that when glass building materials are used for building exterior walls, glass with low reflectivity should be used, and the visible light reflectivity should not exceed 15%.

　　"The implementation of the regulations is good, but the 15% standard cannot solve the fundamental problem." Yuan Bo, an expert from the Science and Technology Committee of the Municipal Commission for the Establishment of Diplomatic Relations, explained that even if the reflectivity is reduced by half, it will still cause strong light reflection to some extent. "Technically, the ideal reflectivity can be controlled to 3%, but this kind of glass costs three or four thousand yuan per square meter, which is several times that of ordinary glass."

　　"When the light is sufficient, the glass curtain wall partially reflects a small amount of strong light, which is difficult to avoid. This is not terrible. The key is that it cannot be reflected to nearby residents’ homes and affect their lives. " Wu En introduced that this is what the Science and Technology Committee focused on.

　　The demonstration is generally divided into two steps: first, draw detailed drawings according to the surrounding conditions of the building, and then analyze the various angles that the glass curtain wall may reflect light, and whether it will affect residents. "When the building is built, it will definitely be too late, and it must be involved when reviewing the construction sketch. If it is not up to standard, the drawing review will not pass. "

　　"As long as light pollution is found during the demonstration, even if it only affects one or two residents, we will never let it go and must solve it in time." Wu En explained, "There are two commonly used remedies: adding a light shield on the outer wall to reduce continuous total reflection; Stick a film on the glass surface to reduce glare. In the event of a dispute caused by light pollution, it is generally negotiated by both parties, with economic compensation as the mainstay. At present, there is no clear mediation method and compensation provisions. "

In the three major parts, there are very few complaints about engine oil emulsification and engine oil increase.

Power performance and fuel economy:

A 2.0-liter naturally aspirated engine is used to simulate a 10-speed CVT continuously variable gearbox with a maximum power of 171 horsepower and a maximum torque of 206 Nm. This powertrain is being used in many Toyota models, including, and, Rongfang and other models.

On the whole, the body size data of this car is almost close to that of Rongfang and not much different from that of CRV.

Market volume models:

Which model is the most popular in the market? Which model is the most suitable?

In fact, the choice of this car mainly depends on two models: the low-end model and the second-lowest model, and the lowest version is the leading version. Combined with the current market volume, the landing of this version of the model is only about 140,000.

The second-lowest two-wheel drive urban version has 16,000 more configurations and 11 more configurations than the entry-level leading version. There are mainly imitation leather seats, electric adjustment of the main driver’s seat, single skylight, leather, full LCD instrument, keyless start and other configurations. In the market, the beggar version is also relatively popular. Personally, the second-lowest version is also good in terms of cost performance.

Fan Bingbing’s cooperation with Han Han was exposed, and the theme song became an extension of the plot

stills
　

　　Fan Bingbing is going to sing again! I remember that this is one of the few opportunities for Fan Bingbing to sing after Warner published his solo album "Just Beginning". And Fan Bingbing is now the Tokyo International Queen, so it is impossible to sing slobbering casually. So what moved Fan Bingbing? It turned out that Han Han and Fan Xiaoxuan, two talented young talents, made Fan Bingbing sing this time. As a well-known writer Han Han to fill in the lyrics, as a musical witch Fan Xiaoxuan to compose the music, not to mention who sang this song, this song combination alone is the first time in history, presumably Fan Bingbing is also willing to go out of the mountain to sing this song for this reason, so why is Han Han, a self-proclaimed noble literary youth willing to write songs for Fan Bingbing? What’s the inside story behind this?
　

Han Han was moved by Fan Bingbing’s "Guanyin Mountain" and said it was very resonant
　

　　Han Han, a representative of the post-80s generation of writers, "a bad boy in the Chinese literary world", criticized ugliness, defied power, laughed and scolded wildly, and criticized the times; Fan Bingbing, the queen of the Tokyo movie, has skyrocketed in popularity and murdered countless films. It stands to reason that Fan Bingbing should not escape saliva when he meets Han Han. However, maybe everyone doesn’t know, but the two are very friendly and cherish each other. I remember hearing that a well-known magazine was going to interview Fan Bingbing, and Han Han immediately asked the magazine to send Han Han a greeting, "Happy birthday to her". If you even remember Fan Bingbing’s birthday, it can be seen that the relationship between Han Han and Fan Bingbing is extraordinary. In this interview, Fan Bingbing heard that Han Han wished her a happy birthday, and said in surprise: "Oh… (5 seconds of long sound) He is so nice! Although my birthday just passed (Note: Fan Bingbing’s birthday is September 16th), I still have to thank him. I’m sorry, I haven’t read many books about Han Han, but I have read several interviews with him in magazines. He is a great boy with a lot of personality. Through his interviews, I can see that his personality may be a little similar to mine. They are both stubborn people." I have never heard of who Han Han wrote songs for, which shows that the relationship between the two is extraordinary. Similarly, Fan Xiaoxuan and Fan Bingbing, the "second fan", are more like sisters.
　

Fan Bingbing, Han Han, Fan Xiaoxuan cooperation exposure
　

　　In fact, Fan Bingbing has already sung Fan Xiaoxuan’s songs in "Guanyin Mountain". In "Guanyin Mountain", Fan Bingbing plays an unrestrained, wild and rebellious bar singer. Her singing of Fan Xiaoxuan left a deep impression on the judges of the Tokyo International Film Festival at that time. It is based on this that Fan Bingbing started working with Fan Xiaoxuan and invited Han Han to work together to create a new theme song MV for the film. It is reported that Fan Bingbing invited Fan Xiaoxuan to Beijing to watch the film through the film director Li Yu. After watching it, Fan Xiaoxuan was so inspired that she made a music sample in a short time. At the same time, Li Yu’s friend Han Han watched the film. Han Han said after watching the film that he had a lot of resonance with Fan Xiaoxuan. At the invitation of the director, Han Han immediately filled in the lyrics on Fan Xiaoxuan’s composition, and the cooperation of the three came naturally.
　

　　In fact, in the eyes of everyone, both Han Han and Fan Xiaoxuan are very talented public figures with great personality. Han Han has always fought against Confucianism. Throughout the history of Han Han’s bombardment, famous debates such as those with Bai Ye, Hong Huang, Gao Xiaosong, Zheng Jun and others. Han Han’s maverick and "rude words" are not for fame (he is already very famous). Because he has his own unique way of thinking and principles of life.
　

　　Fan Xiaoxuan, on the other hand, was also a woman with personality. While the record company was trying to create her image as a cute girl, she did the opposite, playing rock with tattoos and being cynical. She wrote "I Want Us Together", "Crying", "Blue Cheongsam", "Whatever the Music" and other excellent music works with a strong personal style that is unique in the Chinese music scene.
　

　　Both of them were able to let go of their personalities to write songs for Fan Bingbing, which shows how much they like Fan Bingbing and Fan Bingbing’s personality. In fact, if you analyze it carefully, Fan Bingbing is somewhat similar to both of them. Fan Bingbing is also a righteous actress in the entertainment industry, and Fan Bingbing can handle it by himself every time there is a big storm! There is a clear love and hate for people, and if you like it or not, you don’t like it. And all three have their own careers and are the bosses of their own companies. It can be said that it is a high-quality music work jointly created by three strong figures in their respective fields!
　

"Guanyin Mountain" MV is not just a promotional movie
　

　　Maybe many people think that this music work by Fan Bingbing, Han Han, and Fan Xiaoxuan, as well as this MV made by Fan Bingbing and Chen Bolin, is just to promote "Guanyin Mountain" as a selling point, then you are wrong. This song is very important for the whole movie, because it is an extension of the plot. Because Fan Bingbing plays a singer in "Guanyin Mountain". In the film, Fan Bingbing plays Nanfeng, a high school student from a small town who has fallen off the list. He came to the city to explore, and he was confused and confused while working and singing in bars. Fan Bingbing admits that she has many similarities with the heroine Nanfeng. This movie is her confession to her youth that she could not rebel against, and it is an emotion she should have had at that time but could not express. Therefore, songs and music are very important to "Guanyin Mountain"!
　

　　It is because of this that Fan Bingbing, Chen Bolin, and Fan Xiaoxuan gave up their Valentine’s Day and soaked in water to challenge the difficult movements of singing in the water. One soak in water is 10 hours. In order to have a super stunning MV for this work that won him the award of the Tokyo Film Festival, and to thank his friends for their support, Fan Bingbing admits that hardship and tiredness are not the main problems, and hopes that the theme song and film can be recognized by young people. We hope that the theme song of "Guanyin Mountain" sung by Fan Bingbing can become a classic song in Chinese movies like "When Love is a Past Thing", "Holding Hands" in "Wedding Banquet", and "Dry Wine If Sold" in "Wrong Ride". Fan Bingbing said that in "Guanyin Mountain", she experienced the feeling of grasping the tail of youth, not just Fan Bingbing. For Fan Xiaoxuan, who was born in 77 and grew up in the 1980s, and Han Han, who was born in 82, youth is fleeting. The post-80s generation is their collective memory. Like Fan Bingbing, they hope to join hands and dedicate a classic song to sing the post-80s generation together! Singing beautiful youth.

Attention! How to choose 2022 Tang EV？

The 2022 Tang EV that many consumers are looking forward to is finally on the market. The new car of Tang EV has launched three models in total, and the price of these three models after comprehensive subsidies can reach 279,800 to 339,800 yuan. Compared with the pre-sale price, it is relatively cheaper, but it has already hit the automobile market of 300,000. Can BYD Tang EV’s new car occupy a place among the 300,000-class models, and which car is more worth choosing? Then let’s take a look at it in detail.

The 2022 Tang EV still adopts BYD’s family-style design. The front of the car adopts a closed front grille, with split headlights and through chrome-plated strips, and the new Tang EV also adopts BYD’s Dragon Face design language, making it more vivid and beautiful as a whole.

Compared with the old models, the side of the body of 22 BYD Tang EVs has not changed much, and the suspended roof is still designed with raised wheel eyebrows. It is worth mentioning that the wheel hub design of this model of Tang EV is still very clever, similar to the closed design, which will also reduce more wind resistance.

The rear of the 2022 Tang EV is consistent with the old models. It still adopts the design of penetrating taillights, and at the same time, the English letters are embedded in the middle of the taillights to make it more recognizable. At the same time, as a new energy vehicle, it is surrounded under the rear of the car more exquisitely. On the whole, the biggest change of the current model is that the details are improved compared with the old models.

Arriving in the car, BYD Tang EV’s car has a double-color interior. At the same time, in order to make a thorough change, the new Tang EV not only upgraded the interface of the LCD instrument panel, but also upgraded the multimedia system. At the same time, the new car is also equipped with DiLink4.0 intelligent network connection system. The upgrade of this system has also made it have high technological performance, and most of the physical buttons in the car have been reduced to make the car look more luxurious.

The body size of Tang EV is 4900/1950/1725mm and the wheelbase is 2820mm. Compared with the old models, the new Tang EV has increased the body length by 30 mm, while there is no change in other dimensions. However, the increase of 30 mm can’t make passengers feel the improvement of space obviously, and it can leave the feeling for customers. The most obvious thing can only be at the data level.

The 2022 Tang EV is powered by a permanent magnet synchronous motor, and the total motor power of these three models is different. The different power of the three cars brings different cruising range. The exclusive model can bring two different cruising ranges of 600 kilometers and 730 kilometers, while the cruising range of the four-wheel drive flagship model is 635 kilometers. Then let’s take a look at which one of these three cars is more suitable for selection.

2022 EV 600km exclusive type

The guide price is 279,800 yuan.

In terms of safety configuration, the exclusive model is equipped with the main and co-pilot airbags, front side airbags, front and rear head airbags, tire pressure monitoring, front seat belt unfastened reminder, parallel assistance, lane departure warning, lane keeping system, road traffic sign recognition, active braking and fatigue driving reminder.

In terms of auxiliary control, this model is equipped with front/rear parking radar, 360-degree panoramic image, reversing side warning system, full-speed adaptive cruise, four driving mode switching, automatic parking, uphill assist and steep slope descent.

Externally, the car is equipped with openable panoramic sunroof, electric trunk, induction trunk, electric trunk position, memory roof, Bluetooth key of luggage rack, NFC key, keyless start and keyless entry, as well as active closed air intake grille, remote start and battery preheating functions.

In the internal configuration, this car is equipped with a multifunctional leather steering wheel, a 12.3-inch full LCD instrument, a HUD head-up display, a built-in driving recorder and a wireless charging function of the front mobile phone.

In terms of seat configuration, this car is equipped with leather seats, the seat layout is 2-3-2, and the rear row supports proportional reclining. At the same time, it has functions such as front and rear central armrests and rear cup holders.

In terms of multimedia configuration, this car is equipped with a 15.6-inch touch LCD screen, and it also supports satellite navigation and road condition display, road call and rescue, car networking, OTA upgrade, 220V power supply, Dana audio and 12 speakers. All the lights are LED light sources, and there are 5 cameras, 8 ultrasonic radars and 3 millimeter-wave radars on the intelligent hardware.

2022 EV 730km exclusive type

The guide price is 309,800 yuan.

30,000 yuan difference, the overall configuration is not much. Although there are four ultrasonic radars and two millimeter-wave radars, their feedback is not much different in actual use, but the cruising range is improved by 130KM. However, for a car that commutes in the city, the cruising range of 130KM is not enough to be afraid of, even if it is 600KM, it is enough for a week’s commuting. Overall, the 730KM exclusive model is not as cost-effective as the 600KM exclusive model.

2022 EV 635km four-wheel drive flagship

The guide price is 339,800 yuan.

Compared with the mid-range model, this model has a difference of 30 thousand yuan, but the configuration it brings is much higher, but in fact, the only configurations that can be used are automatic parking and steering wheel heating. If the budget is enough, then the top-range model is worth choosing, but if the budget is limited, it is better to choose the low-range model directly.

summary

The 2022 Tang EV really meets everyone’s expectations, and the configuration has reached the configuration required for the 300,000-class model. However, in the final analysis, the three models are most suitable for buying the lowest-equipped model, but if the budget is enough, there is no reason to hesitate to directly match the top model. After all, when the luxury configuration is full, the driving quality and comfort will be greatly improved.

The spring of artificial intelligence creation has come, and the ＂hidden rules＂ of ancient poetry are taught by computer.

　　Xinhua News Agency, Beijing, March 12th Special feature: The spring of artificial intelligence creation is coming.

　　Xinhua News Agency reporter Peng Qian Liu Si

　　"Early spring rain Chu Qing, willow filar silk caught the shore warbler. The painting boat is full of smoke and waves, and the small bridge is light. "

　　Who would have thought that this is a poem created by artificial intelligence with "early spring" as the key word. The author "Nine Songs" was developed by a student team led by Professor Sun Maosong of Tsinghua University Computer Science and Technology Department for three years.

　　Xiao Bing, Microsoft’s chat robot, "narrowly beat" human opponents with a Chinese-style song "Peach Blossom Dream" in the variety show "Wit". When the singer sings such an archaic sentence as "In the boundless night rain, the past is like the wind, the peach blossoms in the ear laugh at the spring breeze, and you and I meet in the dream", many viewers think that this is made by human beings.

　　The spring of writing poetry, composing music, painting and artificial intelligence has come quietly … …

　　Technically, "familiar with 300 Tang poems"

　　Zhou Ming, vice president of Microsoft Asia Research Institute, is a literary lover. He and the research team taught Xiao Bing to write modern poetry, and composing music is a new skill.

　　Zhou Ming said that neural machine translation, chatting robot, reading comprehension and creation are the four main aspects of the application of natural language processing technology, and the difficulty is gradually increasing. Creation is at the top of the pyramid and it is the most difficult to break through.

　　"In the beginning, people couldn’t find how to model creation because it was emotional. Writing poems and writing lyrics are all things with flying literary talents and sudden inspiration, which are difficult to capture. " He said. Thanks to the progress of deep learning and neural network technology in recent years, artificial intelligence creation has won many brilliant achievements.

　　Zhou Ming introduced that writing songs by Xiao Bing is a process of "encoding and decoding". The researchers first trained artificial intelligence robots with popular songs. After sufficient training, you can start writing: after inputting the song theme in the form of keywords, it will be coded into a language that artificial intelligence can understand, and the robot will decode and output it in a way that people can understand, becoming a lyric; Then combine this word with the original keyword as a new input, and you can get the second sentence, and so on to get the whole song word. Similarly, you can also input lyrics and translate them into music scores, that is, you can regard music scores as natural languages, thus completing computer lyrics and music scores.

　　"Nine Songs" learning to write poetry is also "familiar with 300 Tang poems, and you can recite them even if you can’t write poetry".

　　Yi Xiaoyuan, the founder of "Nine Songs" and a graduate student in Tsinghua University, has input more than 300,000 ancient poems since the Tang Dynasty as a corpus, and used the deep learning model to make computer learning. In addition to the rules for leveling and rhyming poems, no artificial rules are given, but computers are allowed to learn the "hidden rules" in ancient poems themselves.

　　"We don’t know the rules of how computers make such poems," said Sun Maosong, which is a "black box" phenomenon of deep learning. In his view, each ancient poem is like a necklace, and the beads on the necklace are words. In the deep learning model, the necklace is completely broken up, and then the implicit association between each bead and other beads is given different weights through automatic learning. When writing a poem, put different beads back into a new necklace.

　　The ancients wrote poems mostly to express their feelings, and the style was sad, which also made the poems written by "Nine Songs" somewhat "sad for spring and autumn". The team hopes to make the "Nine Songs" more positive by strengthening the training of some relaxed emotional samples. In addition, how to write a longer poem on the basis of ensuring the consistency of the whole poem is also a new challenge.

　　In artistic conception, "Kung Fu is beyond poetry"

　　In addition to writing poems and composing music, artificial intelligence has evolved new skills such as writing novels and painting. The science fiction novel "The Day when a Computer Writes a Novel" created by artificial intelligence developed in Japan deceived all human judges and was successfully shortlisted for the Japanese Fiction Literature Award. Google artificial intelligence can also create paintings, and some paintings have been sold at a high price of $8,000.

　　Artificial intelligence has defeated human beings in the fields of chess and cards, video games, etc. Does the latest progress in the field of artistic creation mean that it is not far from surpassing human beings in this respect?

　　Zhou Ming believes that at present, artificial intelligence creation is only based on the imitation of big data, which is far from the creative intelligence of real human beings. "There is not enough data for training artificial intelligence creation, such as the data for composing lyrics; Secondly, the inspiration is not enough, because the data alone is just a follower, writing words and composing music are familiar, and there is no feeling of sudden inspiration in generate. "

　　In Sun Maosong’s view, at present, artificial intelligence creation is a limited creativity, which theoretically does not exceed the creative space unconsciously defined by predecessors in the practice of poetry creation for thousands of years. The ancients wrote poetry as "Kung Fu is beyond poetry", often based on experience, with content and artistic conception, but it is difficult for machines to "express their aspirations" or "express their feelings through scenery" for the time being.

　　Experts believe that the fear that artificial intelligence surpasses human beings in the field of creation is alarmist. "In areas that need deep connotation or inspiration, such as music creation, poetry and prose, I personally think that machines are basically unlikely to reach the state of people, but they will assist people’s creation." Zhou Ming said.

　　However, artificial intelligence can improve the efficiency of professional creators. "If you can’t think of using a word when writing, artificial intelligence will think of a word for you and let you find that you can write like this." For ordinary people, artificial intelligence creation systems such as "Nine Songs" can lower the threshold of creation and realize the dream that "everyone can be a poet, painter or musician".

　　Sun Maosong said that the team plans to upgrade the "Nine Songs" system in the future, so that it can judge the quality of people’s poems, such as whether there are mistakes in rhyme and level tone, whether words are unsatisfactory or sentences are incomplete, and help people improve their creative skills; You can also conduct "humanistic calculation" and quantitative analysis and research on ancient documents through big data.

　　In addition to the creation itself, the study of machine creation can also bring unexpected benefits to other fields of artificial intelligence, and open up innovation in many fields and interdisciplinary subjects.

　　"Before letting Xiao Bing learn music creation, we never thought that music can also be processed by natural language technology," Zhou Ming said. "So once the natural language breaks through, it can drive the breakthrough of cognitive intelligence and the whole artificial intelligence, and there will be many scenes that were unimaginable before."

How do foreign troops ＂play＂ war games？ The gap between our army and foreign troops is not small.

　　Nowadays, computer games are not only a kind of entertainment for game lovers, but also an indispensable means for them to build future soldiers.

　　Computer games such as Panorama Warrior, Call of Duty and American SEAL Task Force have been widely used in the training of American troops and have received good results.

　　With the improvement of the informationization and networking level of the army, various computer games have gradually entered the PLA barracks and become a means of training soldiers. However, due to the controversy over the understanding of the game, there is still a big gap in our army’s use of computer technology to build a "virtual battlefield" and carry out simulation training.

　　Red alert and CS entered the barracks.

　　According to the People’s Liberation Army Daily reported on January 24th, the recruits from the new barracks of Hami Military Division in Xinjiang brought a number of online military games such as Red Alert, tank battle and Counter-Terrorism Elite to the army.

　　The article said: "Tan Huaishang, a college recruit, also designed a set of game maps according to the actual situation of the army by using the map editor that comes with the game Red Alert. This set of game maps sets the terrain conditions and tactical background according to the training topics, and simulates severe weather such as storms, heavy snow and sandstorms, which promotes the improvement of officers and men’s combat command skills and psychological quality. "

　　However, because computer games are a new thing, many PLA officers have not improved the training effect of computer games on soldiers to the same level as that of foreign troops. Therefore, the troops choose to build a "virtual battlefield" by computer games, which is basically in a state of "fighting independently". China National Defense Newspaper once published an article saying: Some comrades’ ideological understanding has not yet reached its due height, and even have a wrong understanding of the "virtual battlefield". For example, when some comrades mention military computer games, they think that it is useless to play more and practice less. When it comes to training, you need a real knife and a real gun.

　　So "Red Alert" entered the military camp and caused a hot discussion among netizens on the Internet. Red Alert, produced by WESTWOOD Studio in the United States, is a real-time strategy game with the background of the world military confrontation pattern in the Cold War era. Netizens think that games like Red Alert are on the side of "free west" and demonize the former Soviet Union and its allies in Eastern Europe. At the same time, netizens believe that real-time strategy games like Red Alert can’t really improve soldiers’ combat skills.

　　However, some people in our army have deeply realized the role of war computer games. China National Defense News reported that in recent years, with the development of our army’s information construction and the construction of local area network, some troops have put a variety of simulation "games" such as main battle tanks, fighter planes, infantry fighting vehicles and car driving into training practice, and the effect is very obvious. The report believes that it is necessary to actively develop military training game software with independent intellectual property rights of our army and adapted to the operational characteristics of our army. At ordinary times, we should be good at planning and organizing a variety of activities such as "online confrontation exercises" and "military game confrontation training", and let officers and men play different roles in various "virtual battlefields" in an organized, planned and purposeful way to adapt to the "battlefield" environment, so as to pave the way for launching live-fire drills for real soldiers, improving their combat capability under the conditions of informationization, and laying a good front stand.

　　The gap between China and foreign countries in war games

　　Compared with the PLA’s new contact with military games, foreign troops are quite "sophisticated" in this respect, and they even "tailor-made" computer game products for the troops. According to Jane’s Defense Weekly, computer games such as "US Army" and "Delta Force" have been designated as training materials by military academies in the United States and Britain. In 2005, the United States Military Academy at West Point alone ordered 1,200 sets of Delta Force game software for daily education and training.

　　In order to attract young Americans to apply for the West Point Military Academy, West Point Military Academy has spent a huge sum of money to develop a new anti-terrorism computer game named "US Army". Since February 2006, the US Army and West Point Military Academy have jointly provided this computer game to high school students and young people for free. Through games, players can experience simulated military institutions and basic training. The shooting part of the game is very real, and the heavy breathing rhythm of the soldiers matches the shaking displayed on the computer screen.

　　In addition, the National Defense Science and Technology Bureau of Singapore cooperated with the University of Southern California in the United States to develop a computer game called "Omni-directional Commander" for the Singapore Armed Forces, with the aim of training soldiers in decision-making, resource management and flexible thinking while playing entertainment games.

　　"Tackling key problems" is the basic way to play computer games in the US military. The military version of game software usually sets levels with different difficulty conditions in the order from easy to difficult. For example, the latest upgraded version of the US military’s "Full Spectrum Warrior" game software has 12 levels. The more complicated the battlefield environment, the more fierce the enemy’s firepower, the more difficult it is to tackle the problem, and the player may "die" at any time. Therefore, players must learn to preserve their combat effectiveness and minimize casualties.

　　According to American statistics, the probability of survival of pilots who have never participated in actual combat is only 60% at the first mission, and the probability of survival can be increased to 90% after computer simulation confrontation training.

　　War games that foreign troops often "play"

　　Us military: using games to trigger the training revolution

　　According to American media reports, so far, Hollywood computer gamers have created more than 500 highly simulated combat games. At the same time, the US military itself has continuously developed various military training games, including both stand-alone games for training individual personnel and online games for class to division scale. Game software such as US Army, Full Spectrum Warrior and Delta Force has become a new platform for the US military to train transformational talents, and is widely used in transformational training programs such as the Army’s Land Warrior, the Navy’s Outstanding Task Force and the Air Force’s Aerospace Leader.

　　According to Pentagon officials, before that, most of the US military training with computer games was to train soldiers to fight alone. With more and more gamers joining the army and the development of computer technology, the US military will fully popularize the use of computer games to train soldiers, and move from individual training to joint combat training, thus triggering a training revolution.

　　Russian army: "virtual battlefield" is extremely cruel

　　According to Russian media reports, the overall development of Russia’s software industry is not backward, and the computer game training of Russian troops is also widely used, but the details are rarely disclosed to the outside world. In the computer game confrontation of the Russian army, in addition to the "man-machine confrontation" mode, there is also a "man-man confrontation" mode.

　　The "virtual battlefield" of Russian ace troops is extremely cruel, and the training games used try their best to improve the difficulty of confrontation. The virtual battlefield game used by Russia’s 76th Airborne Division is that the detachment was thrown thousands of miles away from the big army by the Il -76 transport plane, and was stormed by the imaginary enemy when its foothold was unstable. The enemy even attacked with tear gas, and the soldiers had to fight with the enemy soldiers in tears … Although the game is not a war, the war is not a game, but the game is promoting the change of the war.

Football originated in China, why can’t it be played in modern times？ It has something to do with Zhu Yuanzhang’s prejudice against Cuju.

When it comes to football, I believe many students will think of ancient cuju in China. There is no doubt that football originated from ancient cuju in China. In 2004, FIFA confirmed that cuju in ancient China was the earliest prototype of football. # You don’t know the history of football #

So, when was Cuju invented in ancient China? The "Ju" in Cuju can be traced back to the stone balls in the cultural site of Ding Cun 100,000 years ago. At first, it should be a hunting tool. In the late primitive society, stone balls kicked by feet and hollowed-out pottery balls appeared.

However, it is not known from the development of stone balls to the inventor of Cuju. According to Liu Xiang’s "Bielu", it is said that Cuju was invented by the Yellow Emperor and began to be used in military training. The bow was made of leather and filled with hair.

The earliest accurate and credible written record of Cuju was in the Warring States Policy and Historical Records. In 285 BC, that is, during the Warring States Period, Cuju was recorded as an activity with both military and recreational nature.

When introducing the living conditions of people in Linzi, the capital of Qi State, Qice wrote: "There are 70,000 households in Linzi … which are very rich and real, and all of them are people who play the flute, drum instruments, percussion, playing the piano, fighting cocks, walking dogs, playing six blogs and squatting."

It can be seen that cuju has developed into a popular way of sports in Linzi, the capital of Qi during the Warring States Period.

During the Han Dynasty, Cuju ushered in a period of rapid development. Cuju can be used not only for entertainment and performance, but also for competition and training. It is estimated that many students can’t believe that Cuju will be used for training. This is because Cuju can not only train soldiers’ physical fitness, but also enrich military life.

If Han Dynasty was the first peak of Cuju’s development, then Tang and Song Dynasties was the second peak. After improvement, Cuju started with a solid ball stuffed with hair and became an inflatable ball. Because of the lower cost of football, more ordinary people could afford to play Cuju. With the increase of the number of Cuju, there were teams and norms dedicated to Cuju, and organizations specializing in Cuju competitions appeared in the Song Dynasty.

Having said that, everyone must first think of Gao Qiu, the first master of cuju in the last years of the Northern Song Dynasty, because Song Huizong liked cuju very much when he was the king of Duan, and when Gao Qiu sent something to the palace of Duan, he inadvertently showed a few hands, thus being left behind by Zhao Ji. After Zhao Ji became king, he began to promote Gao Qiu.

During the Tang and Song Dynasties, due to the gradual popularization of cuju, Japan often sent Tang envoys to China at that time, and brought the game of cuju back to Japan. Today, football is still called "cuqiu" in Japanese and Han Wenzhong, which is also influenced by China’s cuju.

Why did China Cuju, which was still at its peak in the Tang and Song Dynasties, fall out of fashion in the Ming and Qing Dynasties? Even after the mid-Qing Dynasty, football turned from export to domestic sales and reappeared in the eyes of China people.

All this stems from an imperial edict of Zhu Yuanzhang. After the establishment of the Ming Dynasty, it was different from the situation that the previous generation used cuju as a means of military training. Zhu Yuanzhang thought that cuju was a sign of being a plaything, because Zhu Yuanzhang had an old rival named Zhang Shicheng, and Zhang Shicheng’s troops liked cuju very much. However, when Zhang Shicheng was at war with Zhu Yuanzhang, it was simply vulnerable. Therefore, Zhu Yuanzhang thought that cuju would not help the improvement of soldiers’ military literacy. Therefore, Zhu Yuanzhang ordered that the Ming army would not be allowed to cuju in the future, and offenders would be punished.

Because this order only prohibits soldiers from playing cuju, but not the people, it actually abandons the function of competition and training, while the people play cuju more for entertainment and viewing.

Therefore, in Ming Dynasty, cuju was still popular among the people, but most of them were women. At that time, cuju was a talent show, just like a brothel woman performing singing and dancing. Although there were several emperors who liked cuju in Ming Dynasty, it was even recorded that the emperor organized eunuchs and maids to play cuju in the palace, but at that time, cuju had developed into a very lightweight thing, and even developed into kicking shuttlecock, which completely deviated from the development of modern football.

During the Qing Dynasty, there were few records about cuju. When the Qing army entered the customs, cuju was banned in the Eight Banners during the Shunzhi period, and cuju was combined with skating, resulting in the movement form of "cuju on the ice".

While the development direction of football in China is crooked, western countries are keen on playing football, and Britain is the first country to popularize modern football.

According to legend, in the 11th century, there was a war between England and Denmark. After the war, when the British were cleaning up the ruins of the war, they found the skull of a Danish invader. They were in resentment, so they kicked the Danish skull with their feet to vent their dissatisfaction. Later, everyone felt that it was very difficult to kick the skull, so some smart people thought of replacing the skull with a cow’s bladder, so there was the origin of modern football.

It can be seen that the birth of modern football itself is full of bloodshed and killing. The initial football match is not just an entertainment, but more like a confrontation.

Generally, two cities take part in a football match. The host throws the football into the air. At the beginning of the game, both sides rush into it, not only shouting, but also running and kicking. Which side can kick the ball to the downtown area of the other side is the winner.

The strong desire to win or lose makes the participants on both sides crazy. In order to win, when the football rushes into the residents’ houses in the middle, the players will rush in and kick around, often leaving the houses in pieces. Therefore, when there is no football match, the people have to close their doors and wait until the end of the game before they dare to leave the house.

Under the strong opposition of the people, the British government had to make a ban, stipulating that football matches can only be played in open spaces, but not in downtown areas, so there was a special football venue.

By 1848, the first written rule of football, Cambridge Rules, was born, which was made between Oxford and Cambridge for a football match. The rule was that only 11 people played in each team, and this rule continued until recently.

In 1862, the world’s first football club was established in Nottinghamshire, England. On October 26th, 1863, the world’s first official football organization, the English Football Association, was established in London, England. This day was also regarded as the birth day of modern football. Since then, with the further improvement of the rules of the game, football has quickly spread around the world.

It can be said that while modern football is flourishing, the ancient cuju in China is evolving into a shuttlecock-kicking sport. Do you think that the decline of modern football in China is related to Zhu Yuanzhang’s ban on military cuju? Welcome to discuss in the comments section below!

China will further improve the monitoring and early warning of disastrous weather.

　　Xinhua News Agency, Beijing, January 10 (Reporter Huang Yao) In 2024, China will further enhance its ability to monitor and warn severe weather and do its best to prevent and reduce meteorological disasters.

　　This is what the reporter learned at the 2024 National Meteorological Work Conference, which opened on the 10th. Chen Zhenlin, director of the China Meteorological Bureau, introduced at the meeting that in 2023, the 24-hour average path prediction error of typhoons in China was 62 kilometers, the best in history; The accuracy of 24-hour rainstorm forecast has reached a new high; The warning signal of severe convective weather was released 43 minutes in advance.

　　Under the background of climate warming, extreme weather and climate events occur frequently and violently. Chen Zhenlin said that meteorological departments should strengthen meteorological disaster risk prediction and response, pay close attention to monitoring, forecasting and early warning services, further improve the linkage mechanism of disaster prevention and mitigation led by meteorological early warning, and build the first line of defense for meteorological disaster prevention and mitigation.

　　According to reports, in 2024, the meteorological department will further enhance the monitoring and early warning capability of severe weather by strengthening the monitoring and early warning of short-term approaching weather, doing a good job in point-to-point accurate forecasting and rolling update, strengthening the construction of national and provincial short-term monitoring and early warning platforms, and promoting the adjustment of rainstorm early warning signals.

　　At the same time, the meteorological department will also improve the emergency response and linkage mechanism for disaster prevention and mitigation, including promoting the full integration of meteorological services into the local comprehensive disaster prevention and mitigation command and dispatch work system, improving the "calling" mechanism and process of high-level meteorological disaster early warning, fully implementing the progressive meteorological service mechanism, encouraging chief forecasters to interpret weather trends and disaster impacts online, and enhancing the prevention capability of meteorological disasters in the whole society.
