A few days ago, the latest population data released by Zhejiang Provincial Bureau of Statistics showed that by the end of 2021, the total resident population of Hangzhou had reached 12.204 million, and the urbanization rate was 83.6%, ranking among the megacities, with an average annual increase of more than 200,000 for several consecutive years.

Since 2019, Hangzhou has been among the best in the country for three consecutive years, and its strength is eye-catching. It is predicted that the resident population in Hangzhou will exceed 15 million in 2035.

Population size is an important embodiment of a city’s comprehensive strength. The resident population of Hangzhou has exceeded 10 million, which fully shows that the urban energy level of Hangzhou is rapidly rising.

Hangzhou ranks first in the country in talent attraction.

According to big data, the supply and demand of talents in Hangzhou, Chengdu and Suzhou rank in the top three, and the supply and demand are booming.

Judging from the distribution of new jobs in 15 new first-tier cities in the past year, Hangzhou has the highest proportion, accounting for 17.21%. From the ranking of the proportion of new first-tier cities where high-end talents are delivered, Hangzhou once again takes the lead. The top five cities are Hangzhou, Chengdu, Suzhou, Nanjing and Wuhan, accounting for 13.02%, 10.83%, 9.41%, 8.31% and 8.02% respectively.

Judging from the average annual salary of middle and high-end talents in the new line, the highest is Hangzhou, which is 188,800 yuan. The second and third places are Nanjing and Suzhou, with 173,400 yuan and 171,000 yuan.

Why do middle and high-end talents prefer Hangzhou?

In recent years, the policy of recruiting talents and attracting talents issued by Hangzhou is very intensive, and the scope of seeking talents has expanded to the whole world, and the threshold for settlement has been lowered again and again, and the support for young talents’ entrepreneurship and employment has been continuously strengthened. Among these policies, people in the workplace said that they were most attracted by the policy of settling down, and the proportion of talents who chose this item ranked first, accounting for 49.26%; Entrepreneurship and employment support policies accounted for the second place, accounting for 28.52%; Subsidy policies such as buying a house and buying a car accounted for the third place, accounting for 22.22%.

Undeniably, the current registered permanent residence is linked to many real life needs and welfare items, such as house purchase, children’s education and medical care. The registered permanent residence is also an important identity symbol for people in the workplace, giving them more sense of belonging and security. Compared with the strict settlement system in first-tier cities, Hangzhou’s settlement policy is relatively loose. Since the "urban grabbing war", the registered population of Hangzhou has surged, and it has been promoted to the blue-chip stocks in the new first-tier cities.

It is foreseeable that with the 19th Asian Games held in Hangzhou in 2022, Hangzhou’s city brand and talent attraction will be further enhanced.

Hangzhou’s urban agglomeration effect continues to increase.

In the Outline of the Yangtze River Delta Regional Integration Development Plan released in 2019, it is clear that Hangzhou is a megacity, and population is the key factor to determine the size of the city. It can be predicted that with the convening of the Asian Games in Hangzhou, the urban agglomeration effect in Hangzhou will be further enhanced.

The resident population is 10 million, which is regarded as a key symbol in urban development. After the breakthrough of the resident population of 10 million, the agglomeration effect of Hangzhou has increased instead of falling. According to Shen Minyue, general manager of Hangzhou Mingju Headhunting Co., Ltd., the first-class business environment is very important.

"The inflow of high-end talents in Hangzhou is not only large in quantity, but also high in quality. There are many other industrial and technical talents recognized by the state, and they are concentrated in the fields of new manufacturing and digital economy, which optimizes the talent structure in Hangzhou and promotes the economic development of Hangzhou. It has formed a good ecology with the business environment." Shen Minyue said. (Excerpted by Jia Xiaoyun, editor of this site)

Poster of Ang Lee’s new work

　 　 Special feature of 1905 film network The winter is getting stronger, and the double eleven is coming again. About ten years ago, this day was named "Singles Day" by netizens led by college students, and it was a melodramatic carnival for the whole people. A few years ago, Ma Yun turned it into a "shopping festival", which was a carnival for all the people. If 2016 is called the first year of high frame rate movies, then this year’s Double Eleven has reason to become a festival related to "120 frames", because this day was officially released.

　

　 　 Before the arrival of this day, "120 frames" has become the most IN-depth industry hot words in recent times. From the early new york test film to the wide praise of the Beijing test film on November 6, these characters with a strong elite atmosphere have almost become synonymous with the "film technology revolution". Strictly speaking, however, the visual revolution brought by Billy Lynn actually comes from the cooPeration of various parameters, and even the single proposal of "120 Frames" is incorrect, because the unit of frame rate is frame /s, or fps, that is, frames per Second … …

Director Ang Lee, joe alwyn and Mason Lee appeared on the red carpet at the premiere of Billy Lynn’s Long Halftime Walk.

　

　 　 If you are not a technical expert, I believe you can look for the fork that closes the page after reading this. Of course, in line with the people-oriented principle of science and technology, the ultimate goal of all film technology innovations will fall on human perception, otherwise it will lose its meaning. So,What different experiences can the new specifications adopted in Billy Lynn’s Long Halftime Walk bring to mankind?And can the perceptual knowledge of audio-visual experience get rid of vague adjectives and find more convincing proof? We consulted some researchers from the medical point of view, trying to get different answers.

　

The charm of afterglow: 24 squares of truth is just an illusion.

　

　 　 For a long time, the frame rate of movies was 24fps, which was derived from a method called "persistence of vision"Physiological phenomenon, this phenomenon has a nice name, calledAfterglow effect. According to Dr. Lei, an ophthalmologist,The human body is a living body full of limitations, such as the visual nerve, which requires a certain reaction time: when light shines on the retina, the resulting image will remain in the brain for a period of time, that is to say, after we see a still photo, even if the photo disappears in reality within a specified time, it has not disappeared in the brain.

Film is actually an "illusion" of human beings.

　 　 Therefore, if we take a group of photos continuously at a certain speed, and then change this group of photos constantly at this speed, our brain will think that we have seen a "moving picture" instead of a group of still photos. Film is such a set of still photos, in other words, it is actually an "illusion" of human beings.

　

　 　 The research shows that when the frame rate of moving images is at least 15fps, the human eye will feel the image continuity; At 25fps, the human eye will not feel the flicker. In the past, movies used 24fps, because it is the minimum standard that can make people think that the picture is coherent under the premise of saving costs. Because of its widespread use, some people call movies ""24 truthfulness”。 The 120fps movie, even if it is played 5 times slower, can still reach the standard of ordinary movies, and the disproof shows the smoothness of its normal speed.

　

　 　 "In fact, the results of the visual persistence function are different in different studies. Some say it is 50 milliseconds, while others say it is 0.1 to 0.4 seconds. This value is limited by other optimistic conditions, such as lighting conditions." According to Dr. Lei’s explanation, we can’t judge the acceptance effect of human eyes simply from the frame rate. Different environments and different principles of image generation will cause different visual persistence time, so the same frame rate has different impressions in movies, TV and computer games.

　

Limitation of human eyes: there is little difference between high and high frame rate.

　

　 　 At first, Peter Jackson adopted the format of 4K and 48fps, which was criticized by many people as "unlike movies like TV". This is because the high frame rate was realized earlier in the field of HDTV than movies, and the general frame rate of TV is 30fps (of course, this is the NTSL standard in the United States, which is 29.97fps, and PAL in China is 25fps), and 120 is the least common multiple of 24 and 30, that is to say, if 120fps can be popularized,

New york Daily News once commented that the high frame rate of 48FPS adopted by The Hobbit is as fake as watching a high-definition football game.

　 　 So, what is the human eye’s ability to distinguish frame rate? "In fact, our eyes are not as sensitive as we thought. Especially in modern society, there are very few people who can use their eyes healthily. Even the most idealized naked eye may not be able to see through everything. As for the human eye’s recognition limit of frame rate, at least in the medical field, there is no universally applicable conclusion. Even if there is, the experimental environment will be different from that when watching movies, televisions and computer screens. "

　

　 　 Dr. Lei believes that the human eye’s ability to recognize 24fps and 120fps is not ideal from a physiological point of view. However, according to the author’s experience of the 3D/4K/120fps version of Billy Lynn on November 6, the clarity and realism of the picture are indeed very different from those of the previous movies with ordinary formats. Dr. Lei’s point of view is: "I believe that increasing the frame rate can improve the visual experience, but can you guarantee that the two experiences are only frame rate changes? Are other technical conditions exactly the same? "

　

　 　 Yes, the 3D/4K/120fps format is a whole. Billy Lynn has brought unprecedented clarity and realism. The resolution of 4K and the projection brightness of 28fl have also contributed, but they are not like 120fps, and the limelight is covered up. The resolution of 4K makes each frame clearer, and the high brightness of the laser projector is obviously more beneficial for us to see what the picture should look like. If these "optimistic experimental conditions" are removed, 120fps will definitely be greatly reduced.

　

Side effects worry: rare and severe dizziness should be controlled for viewing time.

　

　 　 Senior video game players all know that there is a disease that bothers them called "FPS vertigo"When it was released, a word named Avatarheadche was born, which refers to the dizziness caused by 3D movies. Including the VR concept of last year’s fire, the vertigo caused by players in the game has not been perfectly solved so far. Then, when 3D movies appear in the format of 4K and 120fps, will this vertigo be aggravated or alleviated? In medicine, this is also a complicated subject. Dr. Lei said: "Some people are very excited to watch 3D, while others feel like vomiting. Everyone has a different reaction. However, this is somewhat beyond the scope of ophthalmology, and it is related to people’s sense of balance and image analysis ability. "

Avatar set off a revolution in 3D technology.

　 　 In this regard, Dr. Xu, a doctor of neurology, also said that the vertigo caused by 3D movies is complicated and cannot be generalized. "There are roughly two possibilities. One is that because the picture is very realistic and has a strong sense of movement, people’s visual nerves receive motion information, but in fact, when people are sitting in a chair, the vestibular organ in their ears does not perceive motion, and the brain receives two contradictory messages, it will produce a feeling of dizziness. Its purpose is to remind the body. Dr. Xu said that the dizziness in this situation is similar to the principle of motion sickness and seasickness. "But in fact, this reaction of the brain can be changed through repeated adaptation, and it is usually related to the specific visual information content. At least I personally think that not all pictures will give people this illusion, and it is much weaker than the feeling of motion sickness."

　

　 　 "There is another possibility. In fact, when we watch a 3D movie, we will see the so-called ghost without glasses. This is because the stereoscopic effect of the 3D movie is formed by using the distance between the left and right eyes and the difference in viewing angle, and the brain receives two overlapping image information. Sometimes the pupil distance of the glasses does not match the human eye, the images cannot be accurately overlapped, and the focal length of the human eye will become chaotic. However, the brain’s ability to fuse images is limited and has little to do with the clarity of the picture. " At the screening meeting on November 6th, Mr. Bona emphasized the 3D glasses with a cost of $100. This kind of special glasses, together with the image processing in the early and late stages of the film, can effectively solve the problem of image overlap.

　

　 　 Judging from the media comments of the day, it is rare to see the words "dizziness aggravation". This is also closely related to Ang Lee’s attitude towards 3D. First of all, he didn’t blindly pursue huge parallax like when 3D technology was born, and he flew sharp objects to the screen at every turn. Ang Lee has also said many times that 3D made him fall in love with people’s faces and eyes, and this technology is more suitable for expressing dramatic expression tension rather than big action scenes. Therefore, the film as a whole shows the smoothness and smoothness of the lens. Even if we feel immersive on the show and the battlefield, there is no unacceptable shift in perspective, which also forms the comfort that 3D movies should have.

　

　 　 However, from the point of view of eye hygiene, 3D/4K/120fps format does cause some visual fatigue. Dr. Lei said frankly, "The requirements of human eyes on the environment are still relatively high. Too high and too low brightness and clarity will cause fatigue, and long-term fatigue will also cause diseases. But movies are relatively far less than our mobile phones, computers and televisions. After all, ordinary people can’t keep watching movies in the cinema every day, so there are still people in the medical field who are opposed to the popularity of 3D TV, which is also related to the duration. "

　　The Central Meteorological Observatory issued a typhoon blue warning at 18: 00 on May 29: The center of Typhoon Mawar No.2 this year (strong typhoon level) is located on the northwest Pacific Ocean about 640 kilometers southeast of Hualien City, Taiwan Province, China at 5: 00 pm today (May 29), which is 19.6 degrees north latitude and 125.7 degrees east longitude. The maximum wind force near the center is 14 (45 m/s), and the center.

　　It is predicted that Mawa will move to the northwest at a speed of 5-10 kilometers per hour, and approach the east of Taiwan Province. After 31st, it will gradually turn to the north and move to the northeast, and tend to the southern part of the Ryukyu Islands, and its intensity will gradually weaken.

　　Gale forecast: From 20: 00 on the 29th to 20: 00 on the 30th, there will be 6-8 winds in the east of Taiwan Province, bashi channel, Taiwan Province Strait, northeastern South China Sea, southern East China Sea, Taiwan Province Island and its coastal areas, and Fujian coastal areas. The winds in the southeast of Taiwan Province Island and eastern bashi channel can reach 9-10, and the gusts are 11-12. The winds in the sea near the typhoon center can reach 11-14 and the gusts are 15-16.

　　Precipitation forecast:From 20: 00 on the 29th to 20: 00 on the 30th, there will be heavy rain (50-70 mm) in some parts of eastern Taiwan Province Island.

　　Defense guide:

　　1. The government and relevant departments shall, in accordance with their duties, do a good job in typhoon prevention and emergency rescue.

　　2. Water operations and passing ships in relevant waters should return to Hong Kong to take shelter from the wind, strengthen port facilities, and prevent ships from anchoring, grounding and collision.

　　3. Stop large-scale indoor and outdoor gatherings and dangerous outdoor operations such as high altitude.

　　4. Reinforce or dismantle structures that are easy to be blown by the wind. Personnel should not go out at will. They should stay in windproof and safe places as far as possible, so as to ensure that the elderly and children stay in the safest place at home, and the dangerous people will be transferred in time. When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that the strong wind will suddenly blow, and you should continue to stay in a safe place to avoid the wind, and the dangerous people will be transferred in time.

　　5. Relevant areas should pay attention to prevent flash floods and geological disasters that may be caused by heavy precipitation.

Special feature of 1905 film network The one-day box office champion in the past three days is not a Hollywood blockbuster, not directed by Jing Wong, but a less eye-catching youth film — — .

From the fourth place on the first day of the film’s release, the cumulative box office reached 232 million, which has occupied the first place in the box office list for three consecutive days, which surprised many people.

At the beginning of the release, some media revealed that "The Best of Us" was suspected to have a large number of "ghost fields" and was suspected of flooding the box office. This news was also forwarded by Weibo of Jing Wong, the director of the film Chasing the Dragon 2 in the same period.Later, the film released a statement saying that this phenomenon was caused by system problems or special reasons in individual cinemas, and there was no "box office water injection".

At present, this incident is still inconclusive, but judging from the current box office of "The Best of Us", the film has surpassed that released on Valentine’s Day, second only to 354 million, becoming the second highest-grossing youth film this year. A ticketing platform also predicted its box office to reach 379 million.

Massive attack

How does "The Best of Us" achieve a counterattack?

　

From the distribution of "Want to See" data published by a ticketing platform, it is not difficult to see that the female audience after 95 or even 00 is the core audience of "The Best of Us". The proportion of female audience who "want to see" accounts for 76.5%, and the proportion of audience under the age of 24 also reaches 74.2%.

　

This portrait is very different from the Chinese film "Chasing the Dragon 2" released in the same period. The latter wants to see that 69.9% of the users are men, and the audience over 25 also accounts for 54%.

　

　

The Best of Us caters well to the needs of the target audience from the film itself to the publicity focus.

　

Different from the pain-related youth films that prevailed in previous years, from The Best of Us, Hello, Old Times to Warm Hours for Us, the theme of campus sweet pets has always been the explosion machine of youth dramas. This is the reason why the drama version of "The Best of Us" is so popular, and the shadow version also strengthens the "sweetness" in the characters and plot settings.

　

The interaction between Yu Huai, the hero and heroine, and Geng Yan emphasizes "sprinkling sugar" and "CP sense". In the second half, Yu Huai’s leaving without saying goodbye is a routine, but it won the essence of the romantic film "there is abuse in sweetness and sugar in abuse", which provides a good emotional outlet for female audiences who cherish their youth and look forward to love.

　

Compared with the films of the same period, The Best of Us is also more strategic in propaganda.

First of all, combined with the hot topic of "College Entrance Examination", a feature clip of "The Teacher’s Last Reminder before the College Entrance Examination" was posted on Tik Tok Hot Search, which aroused many "memory killings" and the related videos were praised more than one million times.

　

　

Similar to movies such as Sad Than, Ex 3, the promotion of The Best of Us on social networking sites also focuses on the selling point of "tears".

During the road show, the pictures moved by tears of audiences of all ages received high comments and praises, which achieved good sinking communication effect.

　

　

Although "The Best of Us" was not as good as "Chasing the Dragon 2" on the first day, it surpassed "Chasing the Dragon 2" on the third day due to the continuous fermentation of publicity and word of mouth, and finally ranked first in the box office of Chinese films in the Dragon Boat Festival. In the following working days, the film also completed a one-day box office counterattack against X-Men: Dark Phoenix.

　

It is worth mentioning that "Dark Phoenix" and "Chasing the Dragon 2" both belong to sequels, with Zhu Yu as the predecessor, and the audience had high hopes for the sequel, but the quality of the two films failed to meet expectations, resulting in the collapse of word of mouth, with only 7.1 points and 7.6 points on the ticketing platform.

On the other hand, "The Best of Us" was not optimistic before its release, but because the quality of the film was acceptable, people had a sense of surprise beyond expectations. Although Douban scored only 5.8 points, the scores of the two major ticketing platforms both exceeded 8 points, far exceeding the new films in the same period, and it is not difficult to understand the box office counterattack.

IP magic remains the same.

What is the "best" youth film?

　

In 2013, Zhao Wei’s directorial debut won 726 million box office with an investment of 60 million yuan, and it is still one of the most popular Chinese youth films. The low-cost and high-return mode of "To Youth" has also caused capital to flock, which has ignited a large number of homogenized youth film projects.

In June 2013, it was released and won 484 million box office. In the next two years, Tiny Times 2, 3, and 4 were released intensively. Although word-of-mouth disputes continued, the second film with the lowest box office also accounted for 296 million.

　

In 2014, it was released one after another, and the box office was around 500 million. Coupled with the following films, such as "To Youth 2" and "Looking at Paradise with Trees in Summer", youth films ushered in a concentrated outbreak in 15 or 16 years.

Most of these youth films follow the formula of "IP adaptation of hot youth literature+starring traffic stars+derailment, car accident, abortion and other extreme plots". While achieving high box office and high return on investment, they are gradually consuming the enthusiasm of the audience.

For a time, bad movies and dog blood almost became synonymous with youth movies.

　

　

In 2017, youth films entered a trough, with the highest box office of only 64.85 million, which failed to exceed 100 million. Adapted from the sum of popular IP, the box office has not exceeded 10 million mark. The audience has entered the aesthetic fatigue period for this type of youth film.

At the same time, the popularity of a number of online dramas such as "The Best of Us" has also provided new ideas for the creation of youth films.

　

In August 2016, Chang ‘an’s online novel "The Best of Us" was remake into an online drama of the same name, starring Haoran Liu and Seven, and scored a super high score of 8.9. The cumulative broadcast volume of the whole network reached 3.34 billion, making it a phenomenal youth drama of that year.

The popularity of the drama The Best of Us is not only due to the sense of CP that Haoran Liu and Seven, a pair of "bitter CP", overflow the screen, but also because of the delicate and realistic description of high school life in novels and scripts.

　

There are no extreme conflicts or painful youth such as abortion, car accidents and violence, but only simple school life such as military training, examinations, placement of arts and sciences, chorus, and ignorant love.

　

It is under the joint action of "casting the fairy" and the story of grounding gas that "The Best of Us" successfully had a chemical effect with the audience, which made the nostalgic feelings of the post-80 s and 90 s realize a concentrated outbreak.

This time, the film version of "The Best of Us" also continued the success rule of the drama version. Although the actors’ acting skills and adult passages have caused a lot of controversy, and the overall quality is not as amazing as the drama version, the natural display of high school life is still the key factor to impress the audience.

　

This is also reflected in another youth film explosion "Teacher Good" this year. The film looks back at the post-80s youth from the teacher’s perspective in a unique way. Although there is nothing outstanding in the drama and shooting techniques, it still successfully touches the audience with its realistic plot and high degree of restoration.

From "Flash Girl" to "Teacher Good", the youth films that have been well received in recent years are increasingly showing a trend of "returning to reality", which arouses the audience’s sense of substitution and emotional resonance with grounded plots and characters. After all, for most people, youth is not so vigorous, but only those simple little things.

　

In the casting of the leading role, it is no longer just a matter of flow. More and more youth films boldly use new actors with a "sense of youth" and no longer use the so-called star act young to perform. The theme is no longer limited to love, but extends to more dimensions such as family, friendship and teacher-student relationship.

For youth films, IP and traffic are not original sins, and there is no universal law for scripts. In the era when quality is king, the success of youth films will return to the simplest two words — — Good-looking.

　

After all, there is "the best of us" in the youth, so it is naturally not allowed to trample on bad movies at will.

The importance of gearbox for a car is self-evident, and an excellent gearbox may contribute the most to the driving performance of the car. In today’s automobile market, there are also many types of gearboxes, such as manual gearboxes (MT), automatic gearboxes (AT), double clutch gearboxes (DCT), continuously variable gearboxes (CVT) and so on.

(Shift lever of AMT gearbox)

In recent years, in the gearbox lineup of civil vehicles, it seems that the semi-automatic gearbox (AMT) has been expelled from the team, and it seems that it has disappeared. Now the latest news is that it is back, but it has "practiced a martial arts."

Advantages and disadvantages are equally distinct.

The research and development of semi-automatic AMT gearbox began in 1960s. Eaton, Daimler Benz and Scania were pioneers in developing AMT gearbox. The so-called AMT transmission is based on the ordinary manual transmission, which mainly changes the shift control part of the mechanical transmission, that is, by adding an automatic control system controlled by TCU under the condition of unchanged overall transmission structure, the shift automation is realized. Therefore, AMT is actually a robot system to complete two actions: clutch operation and gear selection. You can understand it this way: AMT is essentially a manual gearbox, just a computer to help us shift gears.

(AMT gearbox does not need hydraulic torque converter)

The biggest advantage of AMT gearbox lies in its cost. Compared with the traditional AT automatic gearbox, AMT has no torque converter and surrounding components, and its internal structure will be much simpler. It is for this reason that we used to see it in entry-level cars.

(The driving performance of AMT gearbox is very general)

The advantages are over, and now it’s the disadvantages. Perhaps you should have guessed that the shift quality of AMT gearbox is very general by using manual gearbox to realize automatic shift. Especially when shifting gears 1-2 and 2-3, you can feel obvious frustration every time, because computers are never as smart as people’s right feet. If it is a manual shift, we will be more cautious about the throttle when shifting gears, while AMT gearbox will "rudely" disconnect the throttle when engaging the clutch, and when the clutch is released, it will give the throttle command at once, which is how the sense of frustration comes from.

At the same time, because there is no hydraulic torque converter, the starting response of AMT gearbox is very anxious. Because considering the service life, the computer will not use semi-linkage for a long time, it will only do semi-linkage 2 seconds after you release the brake. Moreover, this force is quite small, and a small slope will cause the car to slip back.

(SAIC clearly marked MG3 with a driving reminder)

I used to drive a MG3 car with AMT semi-automatic gearbox for a long time. My solution to the above two problems is to look at the timing of the gearbox upshift and take the initiative to loosen the throttle to make the shift smooth; At the same time, when starting on a ramp, step on the brake pedal with your left foot, lightly oil the right foot and release the left foot again. Only in this way can we basically avoid these two serious injuries. If you think about it carefully, the purpose of AMT is to reduce the difficulty of driving, but if you adopt this operation, it will increase the learning cost.

Later, due to the lower cost of the dual clutch gearbox, the dual clutch with more perfect experience gradually replaced the position of AMT. Now, there are basically no new cars with AMT semi-automatic gearbox.

ZF let it change?

In order to meet the needs of the market, AMT is also making changes. Recently, ZF officially announced that it has developed an electric semi-automatic gearbox (eAMT) for front-drive hybrid vehicles. This gearbox is a product that integrates the company’s electric drive system (eVD) and semi-automatic gearbox (AMT) into one system.

(ZF eAMT prototype)

ZF brought a prototype car, which also made us understand the working principle of eAMT system more clearly. On the test vehicle equipped with the system, eAMT is installed at the rear axle, and forms the vehicle power system with the front power unit. Because eAMT has its own electric drive unit, it is no longer affected by the interruption of engine traction, and can continuously output power and improve the acceleration ability of the whole vehicle. In addition, eAMT can also output power at the same time as the front power unit, so that the vehicle can realize the electric four-wheel drive mode. In this way, it is equivalent to a low-cost electric four-wheel drive system solution.

I have to admit, as a transmission giant, ZF has a really good understanding of transmission. The core problem of using AMT gearbox in fuel vehicle is the matching with internal combustion engine, which is difficult to do well because of its physical characteristics. The essence of eAMT is a P4 hybrid solution with two reduction ratios, and AMT and engine are completely decoupled. Coupled with the superior controllability of the motor, the calibration difficulty is much lower than that of AMT of pure diesel locomotive.

In this era when new energy vehicles are popular, the matching of power system is no longer based on a single gearbox. EAMT not only achieved good results, but also greatly reduced the cost. This is the greatest value of this system.

Xiaobian language

The advantages and disadvantages of AMT gearbox are very clear. We should make use of its advantages and avoid those disadvantages. eAMT system does this. If this system can be implemented, we can say that AMT semi-automatic gearbox has finally found its own value.

Special feature of 1905 film network Movies, sharing a better life. The film channel specially launched a series of documentary reports on "This Decade, Our Film Life". In this programme, listen to the movie story of actor and movie fan Lang Jiazi.

Looking back on the past ten years, Sophie chose growth, exploration, conviction, persistence and persistence as the key words to sum up. She feels that they are equally applicable in the past ten years or in the next ten years.

There are many predecessors who have impressed her in the past ten years, and many scenes of "Li Wan" in the movie need to break out. At that time, the director would take her to do a lot of exercises.

For example, yelling at the wall at home, or hammering the wall vigorously, vent all emotions to find the best performance state. "The director taught me a lot." Sophie said.

At school, her acting teacher, Chen Gang, often taught her how to behave. "Being an actor can only be done better by staying pure and original on this road."

Sophie said frankly, I hope the audience will be impressed by the role rather than herself in the future. "I hope that in front of Sophie, I can add the word actor."

Lang Jiazi Mi, 27, is a national intangible cultural heritage and the third generation inheritor of "Face-to-Face Lang" in Beijing.

Ten years ago, Lang Jiazi just went to college. Like many young people, when he graduated from college, he fell into confusion and hesitation.

By chance, he saw a video of his grandfather insisting on handcraft, and was deeply moved by his craftsman spirit, so he made up his mind to take dough modeling as his deep-rooted career.

In the last ten years, outstanding countries have been frequent, and the lion dance with non-legacy themes has made Lang Jiazi very resonant. "What is particularly precious is that after watching this movie, I will feel that the protagonist A Juan is a hero and admire him very much."

It took Lang Jiazi fourteen days to spontaneously create a work of the same name because he liked The Lion Boy. He deliberately added a surreal picture. A Juan went to see the scene of lion dance with her parents when she was a child, and she was skillfully integrated into her works, which made her works warmer.

Mermaid … … Many movies accompanied Lang Jiazi to grow up, and he still remembers them today.

In the past ten years, he has also made many attempts on dough modeling. Jiang Ziya, Xiao Jiu, Ao Bing and Nezha, many interesting characters in movies have become lifelike "face people" through his skillful hands.

"The place where dough is shaped is that regrets in real life or the movie world can be realized through works."

Looking to the future, Lang Jiazi said frankly that he wanted to seek opportunities to bring his favorite traditional handicrafts to the big screen. He expects that traditional handicrafts can come into everyone’s lives and that everyone will have a better understanding of traditional culture! "I’m not doing it alone. This is the energy of inheritance! "

?At present, new energy vehicles are all the rage in the mainland market. It is reported that from January to July 2024, the global sales of new energy passenger cars were about 8.48 million, of which 5.55 million were in China, accounting for 65.5% of the global market share. Therefore, automobile brands that have been deeply cultivated in the domestic market for many years, both independent brands and joint venture brands, are actively deploying new energy fields, and even BMW, an iconic high-end luxury brand of fuel vehicles, is no exception. Today, let’s talk about this 5-series pure electric model launched by BMW at the beginning of this year-and see what its experience is?

?

First of all, in terms of styling, BMW i5 still incorporates some electric elements on the basis of its classic brand image. The shape of the coupe is more popular with young consumers. The front face is still a classic kidney grille with angel eye headlights, and the two sides of the lower enclosure are decorated with L-shaped chrome trim strips, and the BMW i5 is also inlaid with the "I" logo at the closed grille, and there is also a circle of blue lines around the grille, which is different from the fuel version 5 Series.

The vehicle size is 5175x1900x1520 mm and the wheelbase is 3105 mm. Compared with the previous generation, the wheelbase is slightly shorter, but the overall size is longer.

The interior space of the BMW i5 is still very interesting, both in terms of technological attributes and luxury temperament. The configuration of the center console is very simple, with color-changing atmosphere lights and wooden decorative boards.

?

The large-size dual screen of central control, including 12.3-inch full LCD instrument and 14.9-inch central control screen, has a clear display effect and excellent overall impression, and its system fluency is not inferior to that of domestic new energy vehicles.

?

In addition, the number of physical buttons in the BMW i5 car is further reduced, and more touch operation is adopted, which is in line with the trend of the new energy era.

?

The seats of BMW i5 are all wrapped in leather, and the comfort is quite good. Although there is no seat massage, the support is sufficient. Thanks to the wheelbase of more than 3 meters, the rear leg space of this car is quite ample, and the seat filling is soft and the wrapping is good. The mobile phone in the central armrest box charges wirelessly, but it does not support fast charging.

Powered by an upgraded fifth-generation eDrive electric drive system, BMW i5 offers two power versions, eDrive 40 and M60 xDrive. Among them, the entry model is equipped with a rear motor with a maximum power of 340 HP and a peak torque of 430 Nm, with an acceleration time of 6.0 seconds from 0 to 100 km/h and a top speed of 193 km/h; The M60 xDrive with stronger performance is equipped with dual motors, with a maximum power of 601 HP and a peak torque of 820 Nm, and the acceleration time of 0-100km/h is reduced to 3.8 seconds. In terms of battery life, thanks to the 81.2kWh high-voltage battery pack, the pure electric cruising range of BMW i5 can reach 536km to 567km, which is enough to meet the needs of long-distance travel. Moreover, the suspension system and chassis of BMW i5 are also remarkable, which is very stable to control and can also bring a stable and comfortable ride experience to the rear passengers during the driving of the vehicle.

?

On the whole, the BMW i5 is still the BMW in everyone’s mind. It has the design texture precipitated by the BMW family for many years, and it has the temperament that a luxury brand should have, both in appearance and interior. In addition, its localization elements are also doing quite well, and stacking materials in the new energy era is also a full plus. Therefore, BMW i5 will be a good choice for users who want luxury driving experience and a new energy vehicle.

Tens of thousands of protesters in Israel called for a truce.

According to CCTV, a special committee of the United Nations released a report on 14th, saying that Israel deliberately caused death, hunger and serious injuries by besieging Gaza, obstructing humanitarian aid, targeting attacks and killing civilians and aid workers, regardless of repeated appeals of the United Nations, binding orders of the International Court of Justice and resolutions of the Security Council. The relevant behavior of the Israeli army conforms to the characteristics of "genocide".

This report will be submitted to the United Nations General Assembly on 18th today. The United Nations said that Israel made genocide in Gaza. In response, a spokesman for the Israeli Foreign Ministry issued a statement on social media on the 16 th, saying that "this report of the United Nations Special Commission is full of prejudice and fabricates anti-Israel content." The statement said that "the Israeli army did not target Palestinian civilians" and that "the only purpose of Israeli military operations in Gaza is to destroy Hamas’s military capabilities, and Israel is still facilitating the continuous flow of humanitarian aid into Gaza.

Students who often read pens can always read one sentence:"It is not difficult to disassemble this computer. You can remove the back cover by removing the bottom screws."

To be honest, this passage is copied and pasted every time.

Because in my opinion, disassembly pays attention to a "logic", and the disassembly logic of most notebook computers isremove a screw→Open the back cover→See the heat pipe fanAll of you here find it difficult because the buckle on the bottom cover is easy to break during the process of opening the cover.

To be honest, it’s okay for most computers to break their buckles.

So in my eyes, what does a notebook computer that is really difficult to disassemble look like?

Today, we will simply analyze it with a typical product:

ALIENWARE M15 R4

Left sliding interface

Left side of fuselage

Right side of fuselage

Rear fuselage

Its configuration is as follows:

I7-10870H processor

RTX3080 8GB discrete graphics card (125~140W)

32GB memory

1TB solid state drive

15.6 inch 1080p resolution 100%sRGB color gamut 300Hz refresh rate IPS screen

17.9~20mm thick

The fuselage weighs 2.28kg

The adapter weighs 912g.

The current price is 31,999 yuan.

Its advantages and disadvantages are as follows:

Advantages!

1, 140W power consumption RTX3080 into the 20mm fuselage, more radical.

2. The hard disk has strong expansibility and is equipped with three M.2 slots (dual 2280+2230).

3, A/C magnesium alloy material, excellent workmanship of the whole machine.

Disadvantages!

1, shielding the nuclear display, affecting endurance (144Hz version is not shielded)

2, there is no numeric keypad.

3, expensive, the average person can’t afford it.

[Upgrade suggestion]

It is difficult to disassemble this notebook computer, because its motherboard is upside down, so only a solid-state hard disk can be added to the cover after disassembly. If you want to clean the dust and replace the silicone grease, you need to disassemble the motherboard as a whole to remove the heat dissipation module.

In addition, the tail is fixed with a separate screw, so attention should be paid when disassembling.

Dual-channel 32GB memory can meet the needs of most purposes. The memory is onboard and cannot be replaced.

The SSD is a 1TB SN730, which supports PCIe 3.0×4 and NVMe.

The machine comes with three M.2 slots, one of which is 2230. If necessary, you can add or replace the solid-state hard disk by yourself.

[Purchase suggestion]

1, the after-sales service has high requirements.

2. It requires high performance and fuselage thickness.

3, Gao Liang’s children

The biggest feature of ALIENWARE M15 R4 is that it is expensive, probably because we knew the price relationship before we got it. The whole machine is designed to feel very advanced, the metal shell is excellent in workmanship and the body thickness is very thin.

Screen aspectThe measured color gamut volume is 106.6%sRGB, the color gamut covers 99.6%sRGB, the average △E is 1.52, and the maximum △E is 2.97. Although the refresh rate of 300Hz is the highest, the resolution is still 1080p, and there is no popular 2K screen.

Noise aspectIts full-load decibel value is 50.8dB, and it is 57.7dB when it is turned on at full speed. It is recommended to turn on the balanced mode at ordinary times.

After-salesALIENWARE has always been the benchmark in the game book. Even in case of screen breakage, water intrusion and other accidents, it can be directly guaranteed. In most cities across the country, you can enjoy the next-day door-to-door service and support global warranty.

Specific policies can be seen in official website, so I won’t go into details here.

The purchase suggestion of ALIENWARE M15 R4 is very simple. You can consider it if you have money. It has excellent workmanship and high-grade brand, and it is a game book that conforms to the status of rich people.

But if you want the ultimate performance release, then this kind of thin game is not suitable for you.

【 Conclusion of Conscience of Pig King 】

The above picture shows the disassembly of ALIENWARE M15 R4, which is a combination of four heat pipes and two fans.

It can be seen that this disassembly diagram only has internal components, and there is no so-called"fuselage shell"That’s because the motherboard is upside down, and we have to remove all the components before we can turn it over to see the heat dissipation specifications of the fuselage.

Room temperature 25℃

Reflectivity 1.00

BIOS version: 1.2.0

Turn on the performance mode. Under full load, the CPU temperature is up to 104℃, stable at 86℃, power consumption is 27W, and the frequency is maintained at 2.2GHz.

The maximum temperature of the graphics card is 81℃, the power consumption is about 135W, and the frequency is 1635MHz.

At the beginning of double baking, the CPU power consumption was as high as 105W and the temperature was 100℃. After a period of time, it was controlled by DPTF, and PL1 decreased and dynamically adjusted until the temperature was below 100℃.

With the double baking, the CPU temperature reached 100℃ again, and PL1 decreased again until 27W was stable.

The graphics card is limited by the temperature wall of 82℃, even if the CPU power consumption is only 27W, it can not maintain the maximum of 140W W.

When the full-speed mode is turned on, M15 R4 can maintain 62W+125W, and the CPU still maintains 100℃.

The surface temperature is as shown in the above figure. The maximum temperature of the keyboard key cap is 47.3℃, the WASD key position area is around 40℃, and the direction key is 32.8℃. The temperature of the left wrist rest is 30.2℃.

Generally speaking, the heat dissipation performance of ALIENWARE M15 R4 is not bad. If it is measured by the requirement of "full blood", it must be mediocre, but this machine is only 17.9~20mm thick, which is very strong.

What is it?"motherboard upside down"Design?

The above picture shows the laptop with the back cover uncovered after the "motherboard upside down" design. You can’t see the main components such as heat pipes because they are hidden on the back.

Today, our protagonist ALIENWARE M15 R4 is the same. When the back cover is disassembled, it can’t complete the operations such as changing silicone grease, but can only carry out simple cleaning and maintenance. This is the shortcoming of the "motherboard upside down" design.

Why does the manufacturer adopt the "motherboard flip-chip" design?

Because "motherboard inversion" can keep the CPU/ graphics card and other heating components as far away from the keyboard surface as possible, thus reducing the C-surface temperature of the notebook computer under high load. (the temperature on surface D will rise accordingly)

For thin notebook computers, they will consider the design of "motherboard upside down", because the machine is very thin, and if it is not upside down, the keyboard will be particularly hot under high load.

After flip-chip, the core is farther away from the keyboard, and the space is larger, so it can be insulated, and the keyboard temperature can be controlled under high load.

In my opinion, "motherboard inversion" increases the difficulty of disassembling, but for ordinary consumers, they generally don’t try to disassemble and maintain, especially for high-end products. Most consumers will choose to hand over their computers to after-sales for heat dissipation maintenance, so it doesn’t matter whether they are inverted or not.

However, if you are a computer hardware enthusiast and like to disassemble and toss hardware, you must be careful of this kind of "motherboard upside down" computer, and the probability of disassembling tragedy is much higher than that of ordinary products.

　　Zhangzidao, where scallops were "affected" three times, was investigated by the China Securities Regulatory Commission in February 2018 for alleged information disclosure violations. On the evening of July 10th, Zhangzidao Group Co., Ltd. (002069, hereinafter referred to as "Zhangzidao") announced that due to suspected financial fraud and other reasons, the CSRC had taken lifelong market ban measures against Wu Hougang, chairman of Zhangzidao, gave a warning to Zhangzidao and imposed a fine of 600,000 yuan.

　　After 17 months of investigation, it was found that Zhangzidao and Wu Hougang were suspected of financial fraud, false records and failure to disclose other information in time. Among them, the 2016 annual report and the 2017 annual report disclosed by Zhangzidao, the Announcement on the 2017 Year-end Inventory of Bottom-seeded scallops and the Announcement on Write-off of Assets and Provision for Inventory Depreciation are suspected of false records; The "Announcement on the Sampling Results of Shrimp Scallops at the End of Autumn 2017" disclosed by Zhangzidao is suspected of false records; The situation that there is a big gap between the annual performance in 2017 and the expectation was not disclosed in time.

　　However, just a week ago, Wu Hougang also publicly stated that "the price was paid for the cognition and awe of risks" and "the loss was sorry for the investors", and said in an interview with The Paper that Zhangzidao had experienced many ups and downs in the construction of marine pastures, and the scallop disaster was a "bumpy" in the practice of exploring marine pastures.

　　The 2017 annual report falsely reduced profits by nearly 280 million yuan.

　　Zhangzidao Proliferation Branch will carry forward the cost of bottom sowing scallops at the end of each month, taking the fishing area (collecting coordinates) of scallops provided by Chengjia and Zhao Ying at the end of each month as the basis for cost carrying forward. However, there is no daily regional record for reference in the whole process, and financial personnel have no effective means to verify it.

　　Therefore, affected by the virtual reduction of operating costs and non-operating expenses, Zhangzidao’s 2016 annual report inflated assets by 131,147,700 yuan, inflated profits by 131,147,700 yuan, accounting for 158.15% of the total profit disclosed in the current period. The total profit in the 2016 annual report was 82,925,300 yuan, and the net profit was 75,714,500 yuan.

　　According to the investigation of the CSRC, Zhangzidao has the problem of random carry-over. In 2017, the recorded fishing area of Zhangzidao was 57,900 mu more than the real situation, and some of the actual fishing areas in 2016 were transferred to the carry-over cost in 2017, resulting in an inflated operating cost of 61,590,300 yuan in 2017.

　　The survey also compared the inventory map of Zhangzidao at the beginning of 2016 with the map of shellfish sowing in 2017. The results showed that some recorded inventory areas in 2016 were re-sown at the end of 2017, although they did not show the harvesting trajectory in 2016 and 2017, and the previous inventory cost should be recalculated according to the cost accounting method of Zhangzidao.

　　Zhangzidao was also suspected of false records in the announcement disclosure of its write-off of assets and provision for inventory depreciation in April 2018. According to the announcement, Zhangzidao has written off the inventory of 1,071,600 mu of shrimp and shellfish, and impaired the inventory of 243,000 mu of shrimp and shellfish, amounting to 577,579,500 yuan and 60,721,600 yuan respectively.

　　However, the investigation by the Securities and Futures Commission found that the inventory of Zhangzidao did not truly reflect the objective situation. Among the sea areas that were written off, 208,500 mu, 197,600 mu and 36,100 mu of shrimps and shellfish were harvested in previous years respectively in 2014, 2015 and the end of 2016, resulting in an inflated non-operating expenditure of 247,828,100 yuan, accounting for 429.1% of the write-off amount. In the impaired sea area, 63,800 mu of shrimps and shellfish were sown in 2015 and 2016, and 0.13 million mu were harvested in previous years, resulting in an inflated asset impairment loss of 11,105,200 yuan.

　　The investigation and accounting results show that Zhangzidao Company’s 2017 annual report falsely reduced its profit by 278,650,900 yuan, accounting for 38.57% of the total profit disclosed in the current period. After retrospective adjustment, its performance is still a loss.

　　False sampling results of scallops: 120 sampling points were planned, and 66 points were not implemented.

　　According to the announcement made by Zhangzidao in October, 2017, the company sampled and measured the bottom-sown scallops (hereinafter referred to as "autumn survey") from late September to mid-October, and disclosed the results of autumn survey at the end of October, indicating that the sampling and measurement work of all planned 120 survey points had been completed according to the original plan, and the inventory of 1.35 million mu of sea area was estimated, and there was no impairment of the bottom-sown scallops of the company.

　　By investigating and comparing the autumn survey records published by Zhangzidao and the navigation positioning information of the ship "Zhangzidao Scientific Research 19" provided by Beijing Beidouxingtong Navigation Technology Co., Ltd., it is found that there are very few points on the ship "Zhangzidao Scientific Research 19" that are confirmed by the navigation trajectory to carry out the plan within the autumn survey days recorded by the company.

　　The survey results show that 66 points extracted from the autumn survey but not actually implemented account for 55% of all disclosed points in the autumn survey. Among them, 19 points out of 21 points in 2014 and 2 points out of 14 points out of 2015 have been actually collected, and at least 21 points in total have been collected before the implementation of autumn survey in 2017. Therefore, there is no need for these points to be sampled.

　　According to the autumn survey plan of Zhangzidao in 2017, the team leader responsible for the specific implementation, recording and reporting of autumn survey is Shi Jingjiang. The CSRC gave a warning to Shi Jingjiang and his team members and imposed a fine of 200,000 yuan.

　　There is a big gap between the annual results and expectations, but disclosure is delayed.

　　In addition to being suspected of financial fraud and false records, Zhangzidao also has major problems in information disclosure.

　　Through the investigation of the company’s annual report and announcement, inquiry transcripts, details and vouchers of the company’s relevant financial data, the company’s scallop inventory map and bottom broadcast map, the sailing trajectory data of fishing vessels and the calculation data of fishing area, inventory and autumn survey records, the CSRC confirmed that Zhangzidao did not disclose the situation that its annual performance in 2017 was far from the expected.

　　In October 2017, Zhangzidao lost more than 10 million yuan a month. In mid-November, Gourong, the company’s financial director, found that the scallop sales data dropped sharply. By the end of November, Zhangzidao’s loss had further increased. After the merger, the profit of the year was only about 50 million yuan, which was far more than 20% different from the annual profit forecast of 90 million yuan to 110 million yuan in the third quarterly report.

　　According to the survey, on January 10, 2018, Gourong, the financial director of Zhangzidao, had learned that the sales loss of scallops in December was more than 4 million yuan. And no later than the beginning of January 2018, Gourong had learned that the company’s net profit in 2017 did not exceed 30 million yuan. "The performance in the fourth quarter of 2017 declined, and the annual performance deviated greatly from the original performance forecast" and reported to Wu Hougang. However, it was not until January 30 that Zhangzidao released the revised announcement of the 2017 annual performance forecast, and then applied for suspension.

　　According to the relevant provisions of the Securities Law, in early January 2018, when Gourong reported to Wu Hougang that there was a big gap between the annual results and expectations, the information was disclosed, and the information should be disclosed within 2 days. However, it was not until January 30 of that year that Zhangzidao disclosed this situation and was suspected of not disclosing information in time. Wu Hougang and Gou Rong are directly responsible persons in charge.

　　According to the China Securities Regulatory Commission’s Notice of Administrative Punishment and Market Prohibition of China Securities Regulatory Commission issued to Zhangzidao, Wu Hougang and Gou Rong were fined 300,000 yuan, and the CSRC took lifelong market ban measures against Wu Hougang and five-year ban measures against Gou Rong and others.

　　On July 10th, Zhangzidao closed at 3.42 yuan per share, down 2.29%.
