The passionate years starting from the college entrance examination

Chapter 258, Unexpected Visitor (please vote for me)

"Leader, can you find more detailed information about Winkelmann's thesis research with Princeton University?"

Hearing Chen Guohua's words, Qiu Zongyue asked in surprise:

"Why do you ask for so much detail?"

In fact, Chen Guohua was not the only one who was very interested in the news from North America. Yu Min and others from the hydrogen bomb research and development team were also very interested.

North America tested its first real hydrogen bomb on Bikini Reef in the Pacific in 1954.

From then on, it was out of control.

Moscow also followed up on the research and development of the hydrogen bomb and completed the test of the hydrogen bomb one year earlier than North America.

However, in fact, the structural problems of the hydrogen bomb developed by Moscow resulted in a relatively small explosion.

Therefore, the accurate time of the hydrogen bomb explosion in Moscow should be five to five years. This is a hydrogen bomb with actual combat effectiveness.

In the original history of time and space, experts such as Yu Min, Sun Jiadong, Deng Jiaxian, Qian Sanqiang, and Cheng Kaijia knew of a foreign newspaper that reported a key experimental theory about the hydrogen bomb.

Later, after Yu Min's calculation verification, it was determined that this theory was wrong.

Radar technology is used for precise positioning, and the cameras they use are also very powerful.

It plays a very, very important role in the field of communication engineering.

Applying digital signal processing technology, in terms of precise positioning, it is directly full.

You know, newspapers are very particular about reporting these news.

Chen Guohua explained this in great detail when he told Dai Xizhang and others about the technology of lidar accessories in the previous aerospace engine laboratory.

It can use the camera on the reconnaissance aircraft at an altitude of 26,000 meters to accurately photograph people about one to two meters on the ground, and can clearly capture the license plate numbers of cars on the ground.

In other words, it can photograph the entire country of Tokyo in one minute, and provide high-definition photos covering the entire Tokyo in six minutes.

China Resources must have received such a newspaper 'very, very accidentally'.

Therefore, we dare not publish random information in newspapers to mislead.

This news makes experts extremely excited. However, it will take up to two or three years to verify this experiment.

Instead of openly informing these theoretical news.

Compared with projects like the hydrogen bomb, it is relatively simple to find out the research trends of Winkelman, the technical director of IBM.

"By the way, leader, I must make it clear to you that digital signal processing technology has a very wide range of applications."

For example, applying digital filters to replace analog filters in communication equipment can miniaturize the equipment and improve reliability.

The reconnaissance efficiency is very high and it is undoubtedly the most advanced reconnaissance aircraft.

"Then I must ask clearly. I must know where they have researched and how they knew they were looking for a university?"

As we all know, from the characteristics of the signals processed by digital signal processing technology, it can be divided into speech signal processing and image signal processing.

Good guy, he doesn’t understand at all.

But they don’t know what steps the mainland has already taken.

As everyone knows, these are all misled by North America.

"This chip uses digital signal processing technology, and the two theoretical pillars of this technology are fast Fourier transform and digital filtering theory."

Chen Guohua quickly explained to Qiu Zongyue:

On the issue of whether to conduct verification, Yu Min and other experts had different opinions and argued endlessly.

"Once the West masters such technology, coupled with the promotion and cost reduction of large-scale integrated circuit computers, the threat to us will be too great."

And since the atomic bomb explosion was triggered at the end of last year, North America, Moscow, London, Frankfurt and other regions had no time to react.

Whether digital signal processing technology has been specifically applied to it, Chen Guohua feels that it must have.

Coupled with this time and space, the emergence of Zhenhua Research Institute, the mainland's blockade of these information has become even tighter.

"Leader, if digital signal processing technology from North America is applied to radar systems, target detection, tracking, and positioning will be more accurate."

"Leader, the reason why the signal of our Huaxin radio product is so stable is because I use a digital signal processing chip."

In this time and space, this has not happened yet.

Qiu Zongyue's brain shrank when he heard Chen Guohua talk about these highly professional technical theories.

Wasn't what he just said clear enough?

Forget it, let’s give a simple example.

Fast Fourier transform and polyphase filter can realize multi-channel filter, and application of sampling rate transform filter can realize modulation and demodulation.

Looking at Qiu Zongyue, Chen Guohua was speechless.

According to the history of the original time and space, the Blackbird reconnaissance aircraft successfully flew in 1964.

In addition, the Blackbird reconnaissance aircraft has an extremely wide reconnaissance range and can complete high-quality reconnaissance missions over an area of ​​300,000 square kilometers in one minute.

"Guohua, tell me, how important is this technology? Why does it pose a great threat to us?"

Applying adaptive filtering can achieve channel equalization, echo cancellation, antenna array beam forming, etc.

In North America, they probably know that the mainland must be intensively engaged in research on hydrogen bombs, missiles, etc.

Nowadays, Lockheed in North America is designing a Blackbird reconnaissance aircraft that uses very advanced radar technology.

But it only started serving in 1968, which is a relatively long time.

The reason is also very simple, that is, it is expensive and has single practicality.

In the original history of time and space, only thirty Blackbird reconnaissance aircraft were built in total because they were too expensive.

There is another reason why North America has a headache because of the long preparation required for each mission.

As a result, such an aircraft, designed by Clarence Kelly Johnson and the fastest flying aircraft in the world, last flew in 1999.

Except for two aircraft used by NASA for high-speed and high-altitude aviation research, the rest were completely retired in the late 90s.

Such a reconnaissance aircraft, which allowed Moscow fighter jets to follow behind it, would inevitably end up being pushed to the exhibition hall.

Since it only entered service in 1968, the Blackbird reconnaissance aircraft must have been equipped with digital signal processing technology.

This is one of the threats!

After listening to Chen Guohua's words, Qiu Zongyue stood up with a frightened look on his face and trembling lips:

"You mean a Blackbird reconnaissance aircraft like theirs can take pictures of the entire country of Tokyo in one minute? That's an area of ​​378,000 square kilometers. How can it do that?"

Why is Qiu Zongyue so familiar with Tokyo’s geographical area data?

That's because he often stands in front of the sand table and the map with other colleagues of the same level to discuss tactical issues.

We have already regarded this place as one of our provinces, so how could we not be familiar with it?

"Leader, please stop asking these questions. It is indeed possible for people to do this. The question is, what measures do we have to deal with it?"

Chen Guohua was very helpless and said:

"The reconnaissance plane is at an altitude of 26,000 meters and flying at Mach 3.5. What do we do to stop it?"

"So I have to understand what kind of progress they have made in digital signal processing technology."

"No, how do you know this information?"

Qiu Zongyue suddenly came to his senses and asked suspiciously. Chen Guohua spread his hands and said:

"Leader, you don't know that you brought out a lot of newspapers before. Princeton University is the world's mathematics center. There are many mathematical theories in it that can be applied in the military field."

"Just like the fast Fourier transform and digital filtering theory I just told you. Once these two major theories appear, combined with large-scale integrated circuit computers, they will appear even faster."

hiss!

Suddenly, Qiu Zongyue couldn't help but take a breath of cold air.

Chen Guohua is probably not a monster, right?

Just after he just said something about IBM's technical director Winkelmann's mathematics thesis at Princeton, he immediately thought of so much?

"Then how do you know so well that the North American Blackbird reconnaissance aircraft has such a flying altitude and flying speed?"

Facing the leader's questioning again, Chen Guohua had no choice but to take out paper and pen and explain to the other party what the theoretical limit value was.

Simply put, the atmosphere is divided into the troposphere, stratosphere and upper atmosphere.

Not mentioning the ionosphere above, etc., just consider these three atmosphere layers.

The troposphere is below an altitude of 10,000 meters, and above it is the stratosphere. This location is also the favorite height for many commercial airliners in later generations to fly.

With an airspace above 26,000 meters, this place is definitely high enough.

Given the flying altitude of many current fighter jets and reconnaissance aircraft, being able to reach 20,000 meters is already very impressive.

For example, the MiG-19 they copied from Liming Engine Manufacturing Factory had a theoretical ceiling altitude of 18,500 meters.

Of course, this does not mean that the MiG-19 cannot go to an altitude of 20,000 meters.

But if you go to an altitude of 20,000 meters, many accidents will occur. This is a height that many pilots dare not try.

You know, the higher you go, the thinner the oxygen becomes, and different conditions such as atmospheric pressure will occur.

At this time, it is a very big test for the technical quality of the aircraft itself.

Maybe the MiG-19 did go to an altitude of 20,000 meters, but it quickly disintegrated in the air.

In this era, North America has already produced B58 bombers and fighters with twice the speed of supersonic speed.

The maximum flying height of the former is more than 19,000 meters, and the flying height of the latter is also more than 20,000 meters, and can even be at an altitude of about 40,000 meters.

That's the theory.

So isn’t it normal for an aircraft like the Blackbird reconnaissance aircraft to fly at an altitude of 26,000 meters?

As for why it must be at an altitude of 26,000 meters, it is because only at this altitude can the entire mission target be photographed to the maximum extent.

Also, if a reconnaissance aircraft is discovered by an enemy missile during its mission, it will also need reaction time.

At an altitude of 20,000 meters, the pilot has a lot of room for reaction.

In addition, there is the issue of cameras. The limit of what can be achieved technically is this level.

"Then our research institute has an optical instrument laboratory. Can you do it to this extent?"

Qiu Zongyue asked nervously after hearing this.

Being able to clearly capture the license plate number of a car on the ground from such a distance is really awesome.

"Leader, there is definitely no problem with this. This is one of the values ​​of the optical instrument laboratory."

Chen Guohua smiled confidently and then brought the topic back.

"Then, leader, I suggest that China Resources Corporation collect relevant papers and information as soon as possible so that we can keep abreast of their technical trends."

"Okay, I understand!" Qiu Zongyue nodded, indicating that he understood.

The discussion on this matter ends here.

As for the reason why Qiu Zongyue came to see Chen Guohua in the first place, hehe, he naturally delayed it first.

As I said before in September, we will look at this matter in December.

Now it seems that November has not passed yet, so the task target has been completed.

Therefore, there is no need to rush to launch the home version of the game console for sale.

The headquarters of China Resources Corporation in Hong Kong welcomed several special guests in the conference room today.

Barzani, Bouteflika, Jibril and Makarim are all guests from the Middle East.

Liu Guanzhong was somewhat surprised when he saw them, three men and one woman.

Guests from the Middle East are really rare.

With Roland Scarborough, the shareholder behind the Peninsula Hotel, acting as an intermediary, Liu Guanzhong had no doubts about the identities of the four Barzani people, but was very curious.

After a few simple greetings, and with nothing to say, Barzani went straight to the point:

"Hello, Mr. Liu, we are here because we hope to get your China Resources Company's 100-micron transistor manufacturing technology and equipment. At the same time, we also hope to purchase five photolithography machines."

"And we want to purchase your company's Huayue calculators, the quantity is 10,000 units"

"If your company wants to use crude oil to pay, then we have no problem."

Hearing this, Liu Guanzhong was quite happy.

Isn't this the big fat sheep that was delivered to your door?

However, Liu Guanzhong is still very curious: Aren't the shareholders behind Barzani's country's Aramco oil company, Chevron, Texaco, Mobil and Exxon, the four kings?

Could it be that they have escaped the control of the Four Heavenly Kings?

As we all know, the power of oil exploration, pricing, and sales in the Middle East is all in the hands of the Four Heavenly Kings.

Two years ago, in 1960, OPEC was established.

But even if OPEC is established, it will not pose any threat to the four kings in a short period of time.

So now that Barzani and the four of them have come to Hong Kong Island to purchase photolithography machines, transistor manufacturing technology and equipment, I'm afraid it's not that simple.

"So these two gentlemen and this lady, what do you want?"

Liu Guanzhong did not answer in a hurry, but asked the other three people.

The four of them came together, but it was obvious that they were not one body.

However, they smiled and shook their heads, indicating that they were together and it was up to Barzani to decide, and they would not interfere in the matter.

Hearing this, Liu Guanzhong immediately apologized, but was quite surprised in his heart.

It seems that OPEC members have made a breakthrough.

It's rare for them to be tough!

In the 1960s, OPEC was formed by five members who met to deal with Western oil companies.

It can even be said that they are trying to deal with non-OPEC oil companies.

But these things have nothing to do with Liu Guanzhong.

Right now it's still about Barzani, so let's settle this matter quickly.

"I can't answer you now about transistor technology and equipment issues."

After a pause, Liu Guanzhong continued:

"But for the two products of lithography machines and calculators, I can answer you now, but you should know that our China Resources Company still has many orders for lithography machines, and it is expected that we will only start producing your lithography machines in the second half of next year. machine."

“So are you ordering now or next year?”

In the past, Liu Guanzhong would never have said this.

But this is indeed the case now. Orders have been scheduled for next year, seventy-eight photolithography machines, not seventy-eight calculators.

Therefore, the difficulty of manufacturing orders is of course very high.

To be honest, Liu Guanzhong is not too worried about the other party not ordering, but if the other party needs to order, they need to pay for the goods in advance and then wait half a year to get the goods.

There is no way around this.

Make it clear in advance to avoid the other party saying that China Resources is a scam.

"What?" McCallum and the other four people suddenly exclaimed, their expressions full of disbelief.

Even Roland Scarlett looked surprised. This was completely different from what he had learned.

Bouteflika spoke directly and asked in a deep voice:

"Why don't you speed up? Aren't you afraid that we will cancel the order?"

Hearing this, Liu Guanzhong smiled slightly, seemingly humble, but in fact he sounded very proud:

"The lithography machine of our China Resources Company is currently the most advanced lithography machine in the world. You may not know that Fairchild Semiconductor in North America also has lithography machines, but their lithography machines are not as good as ours."

"You should have understood the situation in the industry before coming here, right?"

“Cray Corporation, Texas Instruments, and Ector Mochley Computer Company in North America, as well as Sony Corporation, Toshiba Corporation, and Fujifilm Corporation in Tokyo, as well as Stewalk Corporation, Siemens Corporation, Italian Microelectronics Corporation, Thomson and others."

"These companies purchase photolithography machines directly from our China Resources Company. Do you know the reason?" Upon hearing Liu Guanzhong's words, Barzani and the other four were stunned.

As Liu Guanzhong said, they did know some information about the semiconductor and electronic product industries before coming.

As we all know, Huaxin radio, Huayue calculator and "Ping Pong" game arcade are known as China Resources' three major products.

In the past year or so, there has been a craze for electronic products all over the world.

The initiator of this wave is clearly China Resources Corporation.

Many people know very well what kind of company China Resources is.

Now that Western companies such as Texas Instruments, Cray, and Stewerk are cooperating with China Resources, it seems to be sending a signal to the outside world.

That is, the commercial ban in North America has become "in name only", and commercial exchanges between the East and the West have emerged.

Therefore, the radios, calculators and game arcades on the market were all that Barzani and the others could see with their own eyes.

But for the photolithography machine, they only knew about scales, and the information was obtained from other people's mouths, which could not be said to be comprehensive.

Regarding this point, they are just "people are stupid and have too much money" and want to improve the single industrial structure in their country.

At the same time, we hope to develop the computer industry.

why?

At the end of last year, after the explosion in Lop Nur, the whole world was shocked.

In shock, everyone was analyzing: Why?

In other words, why?

One thing that almost the whole world knows is that the Eastern Kingdom was only established in 1949. It was built from ruins.

As for the atomic bomb, it requires a lot of highly sophisticated talents and takes a long time to achieve.

But how could the East detonate an atomic bomb at the end of the twelfth year after the founding of the People's Republic of China?

Later, many Western media and newspapers analyzed that the rise of computers helped the East rise rapidly and replaced the computing power of many mathematicians.

The 'Muhammads' behind Barzani, Jibril, and Makarim saw the reports in the Western media and collected the information through other means.

Came to a conclusion:

The computer industry has indeed been of great help to the East.

Because only this explanation can explain that Dongfang was able to detonate the atomic bomb at the end of last year.

Other explanations are not convincing!

In this case, after a thorough understanding and encountering obstacles in North America and Europe, Barzani and the others finally headed to Hong Kong Island.

They are also not sure whether China Resources is willing to cooperate with the Middle East and sell transistor manufacturing technology and equipment to them.

But, after all, you have to give it a try.

You can't continue to go to the West and get into trouble, right?

That's not being mean, that's being disrespectful to yourself!

But they really don’t know why China Resources’ photolithography machines are so awesome!

Anyway, they purchased five lithography machines from Fairchild Semiconductor Company in North America, but were told that the price was 35 million units.

Obviously they all know that other companies charge 20 million US dollars per unit, but the price given to them is so expensive.

Deceiving too much!

So they came to China Resources to inquire about the price and see if there was any possibility of cooperation.

Previously, they had almost no contact with China Resources.

If there was one, it would be the middleman Roland Scarlett sitting next to him.

The Kadoorie family is not very famous in Hong Kong Island. Liu Guanzhong knows each other very well. The famous Peninsula Hotel in Tsim Sha Tsui belongs to their family.

As early as 1906, Rowland's father, Eli, purchased a large number of shares in the Shanghai Hotel on Hong Kong Island and became the majority shareholder.

Later, as he gradually became prosperous, Rowland's father established Sir Kadoorie & Sons, whose subsidiaries included key companies that monopolized all power supply in Kowloon and the New Territories, and also created the Peninsula Hotel on Hong Kong Island.

Involved in electricity, real estate, trade, finance, hotels, cable cars and other industries, it is a very famous family in Hong Kong Island.

The ancestors of the Kadoorie family have always lived in Baghdad. They moved to Bombay in the 18th century and later went to the capital city.

Later, I came to Hong Kong Island to develop.

It was precisely because of such a relationship that when Barzani and the others came to visit, Roland Scarlett did not refuse.

After all, the Kadoorie family is very nostalgic, and they are also very good at running businesses.

What's more, Rowlands has always had business dealings with businessmen in North America, the Middle East, and Europe.

You know, the company controlled by the Kadoorie family has trade relations with many companies in Europe and the United States. At the same time, the energy of China Electric Power Company also comes from the Middle East.

Therefore, both emotionally and logically, Rowlands could not refuse to be the middleman.

"Mr. Liu, may I know the reason?"

After reacting, Barzani asked in a deep voice.

Not only did he want to know the reason, but even Roland Scarlett was also very interested at this time.

China Resources Corporation is located in Sheung Wan on Hong Kong Island, not very far from Tsim Sha Tsui in Kowloon on the other side.

It stands to reason that Rowland Scarlett should know China Resources very well.

But in fact, the photolithography machine is a high-tech thing, and Rowlands cannot afford it.

So even though he knew full well that calculators, radios, arcade games, etc. were selling like hotcakes, he just wasn't interested.

It's not that he's not interested, it's that he doesn't know anything about technology.

This is very different from electric power companies, because electronic products are an emerging thing and rely heavily on technology.

But now that he had the opportunity to learn more, Roland Scarlett naturally pricked up his ears and listened carefully.

Liu Guanzhong heard this and said with a cheerful smile:

"That's because Fairchild Semiconductor's lithography machine can only produce chips with 5,000 built-in transistors, while our China Resources lithography machine can produce chips with 10,000 built-in transistors."

"Even if your chip design technology passes the standard, you can produce a chip with 50,000 transistors built in."

"In addition, our China Resources photolithography machines are priced at US$20 million each. They only accept reservations and must pay for the goods in advance."

"After the lithography machine is manufactured, we will notify you to receive the lithography machine."

"Of course, don't worry, we will help you pack the lithography machine to ensure that it will not be damaged during transportation, as long as there are no force majeure factors."

hiss!

In the conference room, there was a sudden gasp of air.

Good guys, we only accept reservations and must pay in advance.

No wonder Liu Guanzhong asked them whether to order now or next year.

What a great guy!

"Mr. Liu, what do you mean when you just said, 'As long as there is no force majeure, it will not be damaged'? Could it be that the lithography machine will be damaged during transportation?"

Careful McCallum, her focus is on safety.

Hearing this, Liu Guanzhong nodded and said:

"Yes, there are many optical components built into the lithography machine. These components are very easy to be damaged, so you need to be very careful during transportation."

Barzani and the others, however, focused more on price, prepayment, etc., and discussed this with Liu Guanzhong.

However, Liu Guanzhong waved his hand to interrupt their inquiry and said:

"You just need to answer me, do you want to order now or order next year? Or if you want to order elsewhere, you just need to answer my question."

"You must be clear. Texas Instruments and other companies follow the plan I just mentioned. They pay for the goods in advance and wait for our notification before coming to Hong Kong Island to pick up the goods."

"So you just have to answer my questions."

This attitude is too tough!

Can you still do business like this?

Roland Scarlett, who was standing next to him, was dumbfounded and secretly itchy in his heart.

He was born in 1899 and is sixty-three years old this year.

In his past business experience, he has never had such a tough attitude.

You know, other people come to order goods, and they still have a large amount of money.

Five lithography machines cost US$20 million each, so the total price is US$100 million.

The current per capita salary on Hong Kong Island is only a few hundred Hong Kong dollars, and a large order of 100 million US dollars is expected.

To be honest, Laurent Scarlett needs to entertain and appease this important customer.

As a result, Liu Guanzhong is extremely tough. After translating that sentence: If you like it, buy it or not, if you don’t buy it, get out, don’t waste your time!

Awesome Glass!

Barzani and the four of them suddenly became numb: What should we do?

Should you buy it or not?

They didn't think clearly, so they changed the topic first and asked the calculator if they needed to pay in advance if they placed an order now. And when can I get the goods?

When Liu Guanzhong heard this, he didn't find it strange.

"If you want a calculator, you need to pay half of the price in advance, and you can pick it up in the middle of this month."

The output of Huayue calculators is relatively stable, but sales data are declining.

Although Barzani and the others only needed 10,000 pieces of equipment, Liu Guanzhong still followed the rules.

"Okay!" Barzani, Bouteflika and the others looked at each other, and then said:

"We are now certain to order 10,000 calculators, and we hope to purchase the technology and complete production equipment for 100-micron transistors."

"As for the lithography machine, we still need to think about it again. We will get back to you after a while."

Liu Guanzhong nodded, indicating that it was no problem.

Although the income will drop sharply due to this, if everything is explained clearly in advance, there will be no disputes afterwards.

So, this matter was decided for the time being.

On the Beijing side, Chen Guohua was surprised when he learned that the Middle East was also purchasing transistor technology and production equipment.

One hundred micron transistor technology and a complete set of production equipment are still very valuable now.

But it shouldn’t be expensive in Europe and the United States. Didn’t Barzani and the others buy it?

But you are a bastard who doesn’t want to make money if you have money. Since the other party wants to buy it, he must sell it!

Of course, it won't be expensive, but it won't be cheap either.

"What is Guohua's opinion on technical training?"

Qiu Zongyue, who was sitting opposite Chen Guohua, asked:

"Should we send technicians there to train them or should we have them come to Hong Kong Island for training?"

When Chen Guohua heard this, his eyes widened immediately:

"Leader, why should we send people? Just notify them directly to come to the capital for training. Why do you want us to send people there? Why?"

As everyone knows, last year, the mainland was preparing to sign a contract with British Vickers Airways to order six Vickers Viscount aircraft.

This aircraft is equipped with a Dart engine produced by Rolls-Royce, but it will not be delivered until next year, that is, in 2020.

Now it has been agreed that in two months' time, in January 1963, the mainland will send 12 ground crew members, two pilots, and two translators to study in Great Britain.

Really good guy!

When we purchase other people's products ourselves, we need to send our own people to learn, and we also have to provide translators for ground crews and pilots.

After all, in this era, many people know nothing about foreign languages.

What's more, this involves airplanes! ! !

It belongs to a professional field, and ordinary translation is not enough. It requires a professional translation in engineering.

Otherwise, I’m afraid I won’t be able to learn well!

So, why do we provide door-to-door services for the transistor technology and equipment we sell now?

There is no such truth at all!

Even the current mainland seems to be like a dragon's pond and a tiger's den to foreigners.

However, the purchase of 100-micron transistor technology and equipment was requested by Barzani and the others, and was not a door-to-door sales promotion by China Resources.

Anyway, Chen Guohua would not agree to send someone to Hong Kong Island. It was absolutely impossible!

When Qiu Zongyue heard this, he immediately became happy:

"Why are you so excited? I ask this because I hope that I can complete this order."

"Leader, I don't think your suggestion is very good!" Chen Guohua said bluntly:

"I think you, the leader, should understand more clearly than me why people like Barzani come to Hong Kong Island to purchase our products."

"You don't need to ask. They must have encountered obstacles in North America, so they came to us to seek opportunities."

"We have no intention of treating each other as a big fat sheep to be slaughtered. Since we want to cooperate, we must adopt a cooperative attitude."

"Our products and technologies are world-class. There is no reason for us to be so humble and 'begging' for them to buy our products. There is no need for us to do this to ourselves."

Chen Guohua chattered endlessly and said a lot.

Qiu Zongyue couldn't help rolling his eyes several times. After Chen Guohua finished speaking, he smiled and cursed:

"Good boy, do you think I am a traitor?"

"You criticized me so much for just one sentence, almost treating me like a traitor. You just want to tear me into pieces, don't you?"

"Now that you've finished talking, do you feel more comfortable?"

After hearing the other party's three consecutive questions, Chen Guohua chuckled and said:

"Leader, I have this temper. This is not the first day you have met me. Soon, don't you know whether our products are good or not?"

The leader must not be angry. If he is angry, it will never be like this.

What's more, this is just a discussion, there is no need to go online.

So Qiu Zongyue just nodded to Chen Guohua angrily and funny, and then glared angrily:

"Okay, I won't tell you anymore, you can do your own business."

After that, he got up and left.

Seeing this, Chen Guohua didn't say anything more, picked up a pen and paper and continued the derivation of the previous mathematical paper.

Erdesh's paper to verify the third minor issue of the Riemann Hypothesis has been reviewed by him.

There were no problems with the paper, and the whole process was perfect and smooth.

But Chen Guohua was not in a hurry to hand over the manuscript of his thesis to the other party, nor was he in a hurry to see the other party.

Although he knew it, Erdesh was definitely a little impatient.

But Erdesh should also understand better, that is, Chen Guohua is very busy.

Chen Guohua is very busy now. He is busy writing papers.

Based on the third small problem that Erdesh proved, Chen Guohua also came to inspiration, which is the process of proving the basic properties of the solution to the Navier-Stokes equation.

The inspiration came from Erdez's paper, and more from a conjecture or doubt that Chen Guohua had in the process of proving the Poincaré conjecture.

Poincaré's conjecture involves three-dimensional space, and the Navier-Stokes equation is the existence problem of the solution of NS equations in three-dimensional space. It describes the equation of motion of the momentum conservation of viscous incompressible fluid.

The Navier-Stokes equation has a very special significance in fluid mechanics.

Its existence can be said to have changed the way humans travel in modern and modern times.

For example, in the design process of modern passenger aircraft, the aircraft must be able to fly efficiently, and must fly stably and reliably.

Therefore, in the design process, it is inevitable to use the Navier-Stokes equation to solve these problems at the fluid level.

In the early stages of aircraft design, scientists built planes using rough estimates, physical intuition, and trial and error.

Until now, fighter jets, passenger aircraft, etc. have been widely used, among which aerodynamics was born early, and the basic mathematical tool of this subject is the fluid flow equation.

Because air is viscous and compressible, the Navier-Stokes equations, or some simplified version of them suited to a particular problem, take center stage in the theory.

Then there are cars, ships, etc. These modern technological products are also designed based on aerodynamic principles during the design process.

In addition, the Navier-Stokes equation can also be applied to heart bypass surgery, climate change, etc.

Chen Guohua had actually thought about the Navier-Stokes equation in 1959.

However, the environment and conditions at the time did not allow it, so Chen Guohua shelved the issue.

Recently, he has been spending more time in the aerospace engine laboratory. When studying large drones, he always encounters some relatively difficult mathematical problems.

After all, a drone is also a type of aircraft, and as long as it is an aircraft, it must have something to do with aerodynamics.

Therefore, the Navier-Stokes equation must be used to solve it, or even a supercomputer can be used to solve it.

Because the amount of calculations and equations involved are still very large, it would be relatively troublesome to solve them manually.

However, while Chen Guohua was staying in the office writing his thesis, the phone next to him suddenly rang.

(End of this chapter)
