Chinese entertainment for engineering students

The research at 798 is basically continuous, whether it is the OLED production line or precision processing and precision inspection, so Wang Xu will come over from time to time to discuss with the engineering staff.

The current person in charge here is a Ph.D. graduate from MIT in Chou, Wang Xu’s senior brother. In this era, in the late 1990s, some people who had studied overseas began to come back one after another.

Most of this group of people came out during the early stages of reform and have been studying and working overseas for more than ten years. Some people have taken root overseas, while others have chosen to return to China for one reason or another.

During this period, many people returned to China to start businesses, and many of them came back with overseas investment, such as the famous Baidu Li and Sohu Zhang. But the largest number were actually sent back to China by many overseas companies.

They earned international standard wages. In the early 1990s, they could earn monthly salaries of tens of thousands a month. Later, some of them became entrepreneurs, and some have been active in major foreign companies in China. They are considered relatively high-education workers. An early group of wealthy people.

Later, many popular trends such as red wine, coffee, and cycling were mostly initiated by these people. Together with the self-employed nouveau riche in the 1980s, they formed a group of wealthy people in early China, forming an abnormal The complex and unique culture of the nineties.

"Flowers" is a very interesting movie. It depicts the lives of a group of wealthy people in the 1990s, allowing many future generations to see the somewhat dreamy 1990s.

But in the final analysis, it is just a movie, and the world it depicts is still relatively narrow. The real 1990s will only become more chaotic and confusing. This is an era where fashion and conservatism coexist, and good and evil coexist. This may be the case in every period of change, but it is difficult for people living in it to feel anything in their daily lives.

The huge gap between rich and poor has once again appeared widely in the land of China in this era. Wang Xu doesn't know if this is really good, but this is the power of the times.

No matter what era you are in, you will always have your own problems. As an ordinary individual, a grain of sand in the era is a mountain in your own life. That is not just talk.

What Wang Xu can do is to try his best to help the people around him live a better life, but in fact, the changes caused by his intrusion have already affected the whole country, and are far beyond what a few companies and a few employees can explain.

The increasingly prosperous streets of Dongsi tell the story of the commercial achievements brought by Wang Chao, and the increasingly frequent international academic exchanges at Shuimu University also tell the story of the academic influence brought by Wang Xu.

That’s right, Wang Xu’s current number of papers has surpassed everyone else’s, and has even become increasingly limited to the two categories of artificial intelligence and condensed matter physics.

But today, the formal establishment of the Magic City High-Brightness Light Source Project announced that Wang Xu has once again reached into the field of high-energy physics. This thing was originally just a kind of infrastructure needed for condensed matter research, but it is very, very useful to support the future development direction of this thing.

For example, modulated high-energy synchrotron radiation light sources will play an extremely important role in future condensed matter physics, biomedicine, chemical research, etc. This thing is a high-brightness light source that can clearly see the microscopic world, which can allow many Microscopic research is more specific and accurate.

But it's not too late. If this thing is developed and perfected, and a series of problems including poor stability, short radiation time, and high energy consumption are overcome according to Wang Xu's idea, it can almost be said that the problem of lithography machines has been fundamentally solved at once. Light source problem.

A cheap and stable modulated light source is not as simple as building a photolithography factory to replace EUV in the future. This thing is a light source technology that can be used from now until thirty years later. You can start to build a light source technology from now on. The prototype of a carving factory provides stable light sources of different wavelengths on demand.

Then, based on this light source, various semiconductor lithography equipment, processes and technologies are researched and developed. This is a very targeted technological improvement, which is equivalent to moving forward on a path that can be seen thirty years from now. Don’t be too ambitious in your research. It's directional, okay.

Today is the project establishment meeting, which is very small and held in the back hall of Shuimu's main building. More than a dozen universities across the country and the Chinese Academy of Sciences are participating. Shuimu successfully gained the leadership due to an internal paper written by Wang Xu.

This paper is the one that Mizuki published about twenty years later. It just doesn’t have an experimental verification part, but it has a detailed verification experiment design plan, which is enough for project establishment and proposal.

This actually deviates from the Magic City synchronized light source technology that Wang Xu knew in his previous life, but this technology is more advanced and has better future application prospects. More importantly, this thing was proposed by Wang Xu.

Then, even the Magic City recognized Wang Xu's somewhat metaphysical conclusion that feasibility is often higher. Therefore, Shuimu's School of Science naturally became the main participant in this project, mainly in theory and Experimental verification stage.

What? Shuimu doesn’t have a College of Science yet. It doesn’t matter. The Department of Materials, Chemistry, Nuclear Physics, and the newly established Department of Mathematics, Physics, and Biology have been approved to be packaged together to form the College of Science. From now on, we will be a family. .

The School of Engineering consists of the Department of Mechanical Engineering, the Department of Precision Instruments, the Department of Automation, the Department of Automotive Engineering, and the Department of Thermal Energy, which have been integrated as the main body. In addition, the School of Computer Science has been formed by the expansion of the Department of Computer Science. The School of Liberal Arts is still expected to be restored. The medical school, well, it is obvious that Mizuki has moved towards the kind of comprehensive university of later generations.

Wang Xu didn't have any objections, as long as there was no Academy of Fine Arts. It wasn't that he was discriminating against the Academy of Fine Arts, nor was it that he looked down on the Chinese Academy of Fine Arts. That Academy of Fine Arts was also an institution with fine traditions.

It's about people who engage in art. It's really easy to cause trouble naturally. This is a group of natural liberals. You make them lose their personality and still engage in nonsense art.

Moreover, the style of the Academy of Fine Arts, no matter which one, is actually very inconsistent with the pragmatic style of engineering like Shuimu. It is really difficult to perfectly integrate them.

There are too few girls in engineering universities, and comprehensive universities would be much better. But will there be a situation where a group of male bachelors and a group of female bachelors are incompatible? Well, this is not the problem of the university.

In fact, the male bachelors in Shuimu are not that pitiful. Most of the Shuimu graduates will get married soon, but it is easy for girls to hang out. Regardless of past and present life, Wang Xu has seen many highly educated girls who cannot find a partner even at their age. Yes, of course these girls' lives are not bad, but they are inevitably lonely in the dead of night.

Sitting on the high rostrum, Wang Xu's thoughts were actually a little wandering. In more than two years, this was not the first time that he had sat on the rostrum as the leader of the project. It was even more common for him to be an important participant in the project. .

For such a large-scale scientific research project that most people seem to be absolutely leading, he feels a little accustomed to it. Wang Xu doesn't know how to describe this feeling. It may be the same as Wang Fei winning the Grammy Award for Best Female Singer. It feels almost the same.

That day, Wang Fei said in an interview: "I don't just sing well, and I don't just write such good songs, it's just that you just saw me."

Then Wang Fei dominated the screens of major news media in Chou Country for several days, instantly raising the admiration for her by countless fans.

And while Wang Fei was on tour to receive the award, Wang Xu secretly entered an area in the northwest and presided over the pre-research work of a new experimental engine. Yes, it was his high-altitude and high-speed aerial photography An enlarged version of the detonation engine used in aircraft.

Anyway, he was the one who had the engine taken away by the superiors after he had built it before. He even handed in the design drawings and calculation formulas. This is not the first time that Wang Xu has experienced this kind of thing. You see, there is no such thing in the four-axis The treatment is still being developed in the Aviation Academy.

Recently, Bingdu has also joined in. The reason is that their aircraft factory also wants to start some side business, and it always feels unreliable to just sell vans. So we contacted several key local colleges and universities and went to the Imperial Capital to find Wang Xu for advice.

Then it was logical to join the four-axis team to see if I could do anything for agricultural, police, forest fire prevention and the like.

As for the explosion, Wang Xu no longer paid attention to it. Since it couldn't be used as a toy, forget it. It seemed that it was a bit too much to use it as a toy. Although Wang Xu still fought for a little bit at that time to see if he could keep a model airplane or something like that, but seeing that the superiors didn't let him go, let it go and regard it as a contribution.

It wasn't until last year, when there was a crisis in the southeast, that I heard from Director Jiang that someone made a big model of that thing and flew it into the sky. Then it reached 8 times the speed of sound. Finally, it disintegrated and exploded in the air, leaving a trace in the northwest sky. The next mysterious legend.

Of course, this movement was unfortunately detected by the satellite on the other side of the Pacific. Then, the Chinese side released two more large kickers, and then the Ugly ship immediately turned around, and the strategy shifted to 800 In the sea, into the depths of the Pacific Ocean.

Wang Xu guessed that this was intentional, because he knew that the satellite would be passing through the border before flying. After all, Director Jiang said that he had tested it many times before and collected a lot of various data. That time, it was to test the ultimate speed.

It turned out that defects in the structural processing of the body caused the final top speed to disintegrate before the limit was tested. This also led to a major review at a certain digital factory. However, these were just rumors, and Wang Xu did not actually inquire about it. He even He didn't even ask what his father was doing, let alone this.

Anyway, since he knew how fast that thing could fly, he didn't expect to see it again, and he had completely given up his plans to become a model airplane. It seemed a little early for this kind of thing to be used as a toy for ordinary people. .

In fact, Wang Xu felt sorry for the number factory. The drawings Wang Xu drew were of a civilian aerial photography model aircraft. It was not capable of flying that fast. It is an exaggeration for a civilian aerial photography aircraft to fly four times the speed of sound. All right.

Wang Xu’s analysis is that although the rotating detonation engine is difficult to design, once it is formed, both manufacturing costs, maintenance costs and even relative fuel costs are very low. This is also an important reason why it far surpasses the turbojet turbofan. .

Therefore, it is estimated that this kind of engine will become a commonly used universal engine model in the future, and then it will be widely used in the civilian market.

It's like the high-tech products that Wang Xu obtained from those small devices far exceeded what was necessary. In fact, it is very likely that they are not the accumulation of materials in the system, but in the future, they will be ubiquitous gadgets.

But the things included in that system don’t seem to have any special black technology. At least from the current perspective, even the growth method that runs throughout does not escape the scope of modern technology.

Wang Xu doesn't know if he will be able to unlock something more sci-fi one day, but what he has now is enough to keep him and even the whole of China busy for a long time.

Moreover, Wang Xu is not very worried about what will happen if the system is gone, because a lot of current research is no longer about the things provided by the system, but the system has really become an icing on the cake.

Even if China has no money and no one, it cannot be compared to Wang Xu and a small time traveler. If Wang Xu wants to say that the most successful case now, it is definitely not writing a few songs, praising a few people, and establishing a few companies. The companies that make money don't even develop several high technologies and drive scientific research in several departments.

Rather, he established trust that what he proposed was feasible and could be achieved in the foreseeable future.

This kind of trust has become more prominent in the past two years. Wang Xu now doesn't even dare to open his mind casually. After all, this kind of trust will allow almost any research topic he proposes to be approved in a very short time. , and quickly gathered an almost massive amount of funds.

Not to mention anything else, the investment in the OLED project alone by manufacturers, local governments and the state has exceeded one billion yuan, and the main body of it is actually several major TV manufacturers. Of course, this includes the first-generation factories. Construction Investment.

But even so, such a level of scientific research investment was almost an impossible task for the Chinese people in the 1990s.

However, under the name of Wang Xu, the Ministry of Science and Technology, the Ministry of Electronic Industry, and the National Development and Reform Commission jointly took the lead in coordinating the event and convened several major TV manufacturers from all over the world to participate in the grand event.

Among them are old state-owned enterprises, military-to-civilian enterprises, and even emerging private enterprises such as TCL that have just undergone joint-stock reform. It is such a combination of stragglers, but it happened with Wang Xu's huge reputation and the strong endorsement of the country. A huge joint investment.

When the beautiful colors of the first-generation six-inch small screen were displayed in front of everyone, subsequent funding and construction were no longer a problem. Instead, how to carve up the share became a problem for major TV manufacturers.

The final result was that these companies jointly funded the establishment of a specialized screen production company, and Mizuki also separated the scientific research team in this field and joined that company to conduct corporate operations.

The six-inch screen may be small, but the size is sufficient for a handheld device. The 1990s was a time when various handheld TVs and SVCD playback devices became popular. SVCD players that could be brought on board airplanes were enough to attract everyone. Batch of new users.

And this thing seems to have the ability to become a powerful weapon to break the current format war, which makes TV manufacturers even more confident.

The so-called format dispute, in Wang Xu's opinion, is the fault of entering the market. Well, in fact, in the eyes of others, it is still Wang Xu's fault.

Due to Wang Xu's excessive intervention, VCD, a small piece of land, has blossomed into an amazing brilliance in China very early. The decoding algorithm is open source on GIT. The dedicated decoding chip was proposed by Wang Xu and developed and designed by Imperial Digital Factory. The chip tape-out and subsequent production and packaging are all OEMed by Magic City. The audio decoding is also made by Wang Xu.

The laser head comes from the new semiconductor laser head developed by the Mizuki Electronics Department, the mechanical structure is the work of the Precision Instrument Department, and the stepper motor is made by the Motor Department, and all of this is lying quietly in the patent pool.

Then, as the name of Shuimu Patent Pool spread more and more widely, countless southern business owners came here to hunt for gold. Such a complete set of film and television solutions was placed there, which naturally aroused the interest of many manufacturers.

Then there will be a melee between dragons, such as Ai Duo, Backgammon, and Xinke. It will be a lively fight.

Overseas film producers have always had little interest in VCDs. Even the chips are made by Didu Company and the laser head is produced by Modu. In the beginning, imported motors, movements and other mechanical parts were needed.

But since a movement-producing company in Shenzhen went into production last year, there are really no Western parts in the entire VCD.

In the early days, Europe and the U.S. had almost no income in the field of VCD, and patent fees and copyright fees were even pitiful, so it was natural that copyright issues directly blocked the overseas sales of VCDs.

Then the small-life companies began to work hard to promote their DVD concepts and related products, even earlier than what Wang Xu had experienced in his previous life.

After all, DVD has a much larger capacity and can accommodate higher-definition images. And relying on their local advantages, they quickly gained support from major Hollywood and small-time film manufacturers, as well as TV stations, and gained a wide range of image resources.

But this thing, for Mizuki's patent pool, it is really not difficult at all. After all, the compression format has long been disclosed by Wang Xu.

In the GIT community, the various formats of MPEG, plus various processing of stereo, surround sound, live sound, simulated sound field, and multi-track reverberation, are long-established open source systems that can be used casually, 伱 said How much technology can there be in a DVD format that is still 480P?

The technology of the DVD disc itself does not have any big barriers. This level of processing accuracy is really not an insurmountable bottleneck.

Then, under Wang Xu's instigation, several optoelectronic companies and scientific research institutes joined forces to create a brand new China-led disc.

If we have to make a comparison with the experience of Wang Xu in his previous life, then this new disc should be called Blu-ray.

Who allowed this generation of blue light semiconductors to be born in China? Along with it, blue semiconductor lasers were also born in China. This was the confidence they dared to come up with a completely new format.

However, at this time, China still had many shortcomings that it could not overcome, such as problems with the accuracy and stability of mechanical processing and manufacturing, problems with the speed and accuracy of motors, etc. This eventually formed a kind of problem that had not been achieved in previous lives. New discs that have appeared.

This is a disc with a slightly smaller capacity than a DVD disc, because although it uses shorter wavelength blue light, it only uses a single-layer disc structure, and the density is only slightly higher than that of a traditional CD.

But even so, if it is made the same size as a VCD, it can achieve a single disc capacity of up to 10G. This number is actually much inferior to the Blu-ray disc used by Wang Xu in his previous life, but for China now , this is an incredible achievement and progress.

In other words, this is the first time that China has taken the lead in establishing the rules of a brand new storage medium. This optical disc format is officially named Blu-ray Disc, or BRD in English, which is simple and crude, and Chinese tradition.

After discussions with industry associations led by the state, two different new optical disc specifications were finally established. One is a five-inch optical disc that is the same size as a CD, which is also the same size as a DVD, and is called BRD-1, which stands for The meaning of single-layer BRD is that in the future, one more layer can basically increase the capacity by 10G, and then make it double-sided, which can double the capacity. However, this will only be achieved after industrial capabilities are gradually improved.

This five-inch optical disc is not used as an image carrier, but is simply launched as a storage medium that can store 10G of data, which is slightly larger than the newly launched DVD disc format in the West.

What is used for image storage is a three-inch format with its own external packaging. It is similar in size to a three-inch floppy disk, but can store up to 3G of data information. It is called BRD-MINI.

This capacity is enough to store a 120-minute 480P MPEG-II format movie, which is also an important reason why the industry association defines this size as an image storage medium.

Based on these two types of optical discs, the manufacturer of VCD chips soon launched a new chip that used the MPEG-II compression format and also brought various sound field decoding. After that, SVCD turned out. .

In fact, according to Wang Xu's idea, everyone should use the BRD-MINI format. After all, using five-inch discs to store movies is a waste of space.

But later, some VCD manufacturers, in order to continue to be compatible with previous five-inch discs, designed and launched machines using large BRDs, named SVCD. In the final analysis, they are just for image storage, and large discs are nothing more than a little more waste.

Then I discovered that in the pirated market, the price of a five-inch BRD disc is the same as that of a three-inch disc with a protective cover because it does not have a protective cover and some materials are shared with previous CDs. Can be cheaper.

The final result is that the market finally chose 5-inch disc products, and the sales volume was several times greater than that of three-inch disc machines. However, pirates are still very powerful and still provide sufficient supporting support for three-inch discs. , otherwise none of that three-inch disc player might be sold.

The market is really amazing. It really does not take the will of the original designer into consideration. It will make its own choices, leaving the designer stunned.

The final result of the competition is that with the various marketing and advertising of the manufacturers, this generation of video disc players has a common name, SVCD. The three-inch BRD-MINI, which was born for video discs, almost no longer has its own name and is called for small SVCD.

Okay, it's okay to go back to the track of the previous life. Wang Xu thought this might be a kind of tribute.

From storage media to reading methods and even compression formats, DVD and SVCD are different. Each side has its own fans and supporters. This is the so-called format battle.

There is no obvious difference in image quality between overseas DVD and China's BRD format. The DVD image quality is slightly higher simply because the compression is not as severe.

However, DVD is a standard jointly launched by Xiaori and Chouguo and several major European manufacturers. It is supported by the mainstream in the West. It has a wide range of genuine film sources and is supported by major international manufacturers.

After all, BRD came from a humble background and could be considered a pure Chinese blood, something he secretly made on his own.

Although the technology is powerful, the capacity is large, the speed is fast, and there are many advantages, and because it is produced in China, the price is lower. There is also a three-inch version of the product, which is small in size and comes with a protective case, which is a leading advantage.

However, this standard has not received any genuine support, and it cannot enter the Western world at all. It is not that it is not allowed to be sold, but that there are no film sources, and no one will buy it at all.

However, fortunately, within China, these are not problems, and they are not even big problems in Southeast Asia.

Soon China was full of pirated copies. Who made it open source on GIT that there are two format conversion programs? It can be said that if you have a new DVD disc over there, the pirated SVCD here will follow immediately. When it comes out, it's called a quick connection.

This is a competitive situation that did not appear in the previous life. After all, the SVCD technology in the previous life was not that powerful.

And by the time it came out, DVDs had almost dominated the world. Relying on the huge Chinese market, VCD and SVCD, two truly Chinese products, have supported a large number of domestic electronics manufacturers.

But that's just domestic. Overseas, at most, we can bring Southeast Asia and the big bears that are still struggling in chaos. Oh, by the way, and later Africa, where this thing is also sold.

As a result, the Western camp has almost become a restricted area for VCD. DVD has also imposed an embargo on China in almost every sense. Technical standards and processing equipment have not been authorized for Chinese manufacturers, and China has basically not reaped the dividends of OEM for them.

Although DVD products have opened the country due to the WTO, finished models are also sold in China. However, since there are no Chinese film sources, audio and video products are not unconditionally accessible. The threshold is an order of magnitude higher than imported machines.

In addition, the piracy of DVDs is extremely rare. The result is that the DVDs sold in small quantities in China have completely become a drinking tool for a few wealthy families and cannot be sold at all.

Moreover, the difference in picture quality between the two, well, as far as most household TVs are concerned, there is no difference at all.

From VCD to BRD to finished SVCD, it can be regarded as China's first product that can be said to be innovative. It has really had a big impact in this life, and it has earned Huaxia a lot of face, although it has been sued a lot due to piracy issues.

Especially with Xiangjiang as a transfer station, all waterways can go smoothly. Almost all of Southeast Asia is producing pirated products in various languages.

Then with the spring breeze of the World Trade Center and the pace of piracy, VCD and even SVCD machines themselves naturally went out of the country and moved to the vast third world countries.

Don't underestimate these third world countries, especially Southeast Asia. They have an earlier development experience than China. The term "Asian Tigers" is also a real economic miracle that was once famous.

Coupled with the huge population base and the huge proportion of Chinese there, SVCD has actually been integrated into the daily life of Southeast Asians faster than the DVDs controlled by Xiaori. They are just living their lives. The only pirated SVCDs everywhere are genuine DVDs. Which would you choose, right?
