Rule system

How does Zhang Hongtao also want to understand why Zhao Wei is capable of accurate importing plates containing elemental components.

'', is 93 elements.

This period of the period is ranked, and the domestic research is still very small. Some materials have been added, almost all imported abroad.

Experts replaced by alloy materials, I want to say it directly to the sheet, almost can only rely on guess, because the elements have been represented by the elements, how can the metal elements that can be added, how can I know it?

Zhang Hongtao does not understand.

At the same time, he doesn't think Zhao Yu has just been a lot, and that looks seem to be determined to contain .

It's not joking.

Zhang Hongtao took the doubts to follow Zhao Wei all the way, he constantly looking for topics and Zhao Yisi chat, the topic is basically related to the material, alloy is related, he is a testistic conversation.

Zhao Wei constantly following nodded, hardly talk.

Zhang Hongtao seems to have to let him express some opinions, but Zhao Wei does not understand what he said, the metal element is to know that the elemental cycle table will also be back, but what all the manufacturing, a metal is warming to how much What is the effect, what is the color of a rare metal?

How can this be knowing!

Zhang Hongtao said very professional, all the knowledge of metal materials, alloys, etc., Zhao Wei can only listen to nod, it seems to be a look, actually in the heart, "this guy said It is Chinese, each word, each word, some of the meaning of a sentence, I understand why I don't understand why the whole is put together ... "

When Zhao Wei did explain, Zhao Wei said, it is 'Occasionally to look at' material learning, the words have been said, it must not understand anything.

So it will open when you can open.

For example, some of the limited answers.

"Hey and aluminum are blended in some way, will it make it more resistant to high temperature?"

"The carbon element that is adjusted, is the proportion exceeds 0.5%?"

"Is there a possibility to add two rare metal elements to create a more high temperature, sturdy material?"

Zhao Wei's answer is 'Yes' and 'not'.

the reason?

He will not explain carefully.

Anyway, the two are dialogue in the form of chat. It seems to be discussed academic issues, essentially just talk about a chat, Zhang Hongtao has no way.

After this road came over, Zhao Wei did not want to stay with Zhang Hongtao.

After waiting for the metal material experimental base, he quickly got to Liu Guangzo, and found that Liu Guangzuo is still very nice.

least……

This guy will not talk about what metal material.

Just in order to talk to Zhang Hongtao, he also made a certain understanding of the materials, he also spent 20 points of energy, using the "cause" to find the answer.

20 points are equivalent to two learning coins, don't have much, but there is no meaning!

the other side.

Zhang Hongtao stood at the door of the materials laboratory, looking at the far-depends, and the heart was more curious about Zhao Wei.

When he was talking to Zhao Wei, he had deliberately asked some questions, and several were all right than Zhao Wei.

It can be said……

As long as he knows questions, the other party is right.

In this speculation, those who don't know the answer may be the right thing.

Although Zhang Hongtao feels very surprised, Zhang Hongtao feels very surprised.

These are not related to chemistry!

If Zhao Wei has a certain study in the field of metal materials, it is really incredible.

He is a full range of people!

"Have the opportunity to ask, I have encountered problems in research?"

"Maybe ... can he give a useful opinion?"

Zhang Hongtao thought will be more and Zhao Wei in the future.

The other party is a real genius.

Although it may be in the field of chemistry, materials, the basic knowledge is not stable enough, but some ideas, some ideas may be very creative.

Scientific research needs to be creative.

After a large group of people left the material laboratory, they also visited the two teaching buildings, including the postgraduate experimental building, and then returned to the computer laboratory building.

They squeezed into small conference rooms.

Zhao Wei was arranged in the front row. He looked around and found that there were three or forty people in the meeting room.

This number is absolutely a lot.

Although I can't catch up with the large research, I have to know that the minimum standards are associate professors (deputy researchers), including two academicians, including the national navigation system, the designer Liu Yan, and there is the capital aerospace University computer academician.

Zhao Wei was arranged in the first row, probably because of the research results, he has the world's top results in mathematics, physical and computer, and the academic circle is like this. There will be corresponding identities.

Even if he is just a meeting of the identity of the intelligent and automation laboratory (internship researcher), it is still arranged in the best position, others have no opinions.

But Zhao Wei does 'not use'.

The content of this meeting has been determined, which is the work of the error correction coding in the positioning system.

The Capital University of Aeronautics and Aerospace is to design and correct the code. The smart and automation laboratory of Yanya University is smaller, only part of the work, which is approximately equivalent to one quarter of the overall error correction.

This workload pressure is also very big.

Error correction coding refers to the code that can be discovered or corrected after the receipt during the transmission process.

This encoding has the ability to detect the error and error correction, you need to increase excess symbols between the original code words to expand the difference between the code words, that is, turn the original code according to some rules into a certain remaining codeword. And there is a certain relationship between each codeword code.

The above explanation seems to be a bit complex, simple to understand, and after each part of the source code, a part of the error correction codes will be added to detect problems such as errors, missing during the information transmission process.

Error correction coding discovers errors, it will automatically correct it.

The error correction coding is important because the information transmission process is likely to be lost.

For example, a message: 1234567890.

When it is transferred to the terminal, it may become 1234560, 789 three characters are directly lost.

At this time, the role of error correction coding is reflected, and the encoding will automatically detect the integrity of information transmission in the way, and discovers the problem will be corrected in time, add.

The existence of error correction coding guarantees the safety and integrity of the transmission, and the information can be transferred in a plurality of ways, not too much packet loss in the process.

The above explanation is almost understandable that the workload of error correction coding is much.

The first flight of the computer is responsible for this work. He has designed a framework for correcting the code.

and many more.

After the end of the allocation work, it is to discuss the sharing of information during the research and development process, because the whole is a thing, they need a team to cooperate, and the code must have a connection between the code.

The meeting was held very smoothly. The only special is Zhao Wei, he has already slept from the past, because the whole content does not have any relationship.

Liu Yan En invited him to come over. It is said that he wants him to make an opinion, but the overall framework is done, it is equal to work, it has been arranged, and there is no way to assign it.

It is better to have a harvest.

[Extra rest, learning coins +2.

[Extra rest, learning coins +2.

[Extra rest, learning coins +2.

The system prompt is really unexpected.

"Can you get a rest while when you have a meeting?"

"This is good."

Of course.

The sequelae is also very big.

When I was in class, the teacher won't take too much. When I meet, I didn't have anyone. I can see the old professor who laughed in both sides. Zhao Wei didn't know what expression.

"Cough ... I didn't sleep well last night." He explained a sentence.

"Is it thinking about the brother?" A don't know the old guy, I said on my face.

"Cough ... Yes, yes."

"I have heard that you are studying the brother guess, is there a progress?" The old guy seems to have been guessing his own guesses.

"One thing."

Zhao Wei's answer is some surprised.

The old man is big and asked, "I really have progress? Can you talk about it?"

"Over!" The other person is joke next to another, the old guy also knows that he has some excessive, and the mathematics research of others will definitely not disclose the message before no determination.

He just was just too surprised.

Zhao Wei said, "I just determined which method of this, the real results have not yet now."

"It turned out to be like this."

Several people around them nodded.

This is right!

That is, Gotbach guess, it's almost half a century, no progress, even if Zhao Wei is the genius of the number, such a short time, it is impossible to make a result.

Several people only said a few words.

The meeting is over.

Most people discuss the content of research work, and Zhao Wei is nothing to do. He looks around, thinking is that he will go back, let Liu Guangzuo have communicated here, did not expect Liu, I found him. .

Liu Yanzhen sat next to him, and he knew something like a look.

Zhao Wei wanted to hurry, but unfortunately, he can't walk, he was depressed to Liu Yan En, I would like to listen to the specific thing.

Liu Yann smiled, "This invitation you, mainly not to correct the code, but want to talk to you."

"Math problem?"

"Is information compression, transmission, and multiple data positioning calculations."

Liu Yan En interpreted a sentence, then asked, "Do you know information compression?"

Zhao Wei nodded.

Liu Wei En said, "Our satellite performance is still high, absolutely the international top level, but there is still a big problem on signal compression transmission. Mainly lack of mathematical theory."

"There is a new digital compression technology in the international international, have you heard?"

Zhao Wei continued to nod, he certainly heard that he was designed with Tao Zhexuan, and also specially applied for a patent, and his name is also his name.

Liu Yan En thought about Zhao Wei probably not understanding, nodding is just symbolic, and then explains, "We hope to improve the performance of satellite imaging in algorithms, that is, the satellite, shooting of the future, shooting Higher, can store, transfer more image data, and it is also desirable to be more accurate. "

"It is good to say that it is only necessary to do more, the former needs a systematic theory support."

"Previously, our program is designed to be chaotic, all of which are stitching together, we want a system compression technology ..."

Liu Yan En explained, generally, because the problem of algorithm caused the efficacy of transmission data too low, I hope to have a large set of mathematical theories, to support a new set of compression technology, you can put it on the satellite, enhance the satellite data capture , Transmission, etc. performance.

Zhao Wei listened to the nodded.

When Liu Yuen explained in detailed explanation, he only opened, "Use traditional algorithms must not work, data compression improvement performance, is simplified the amount of information of capture data, increase the amount of information of analysis data."

"It is best to make the quantity of the decompression amount above the compression."

"Mathematically, it is to use simple information to shape complex functions. We only need to record simple and joy, and then analyze complex functions when you decompression ..."

"Correct!"

"Is such that!"

"It makes sense!"

When Zhao Wei's explanation of mathematics, several professors were surrounded. They first heard what the two were chatting. After Zhao Yu opened, it seems to become a personal class.

Others can only follow the "right", "no mistake", "reasonable", "too reason", and so on.

At the same time, they are also surprised.

Data compression is a very strict area of ​​computers and mathematics, but mathematics should be scored in application mathematics.

Zhao Wei is indeed one of the top mathematicians, but the area of ​​his good at the quotation of the number, not the application of mathematics.

There are too many fields in mathematics.

Many domestic many students do are complex mathematics, such as partial micrographs, topologies, differential geometry, etc., all academicians of this area have several.

The number of research and complex mathematics is a certain hook, which can be said to be very close to each other.

Application mathematics is different,

Applying mathematics and complex mathematics is more close, and the relationship between pure numbers is a lot.

They really didn't think that Zhao Yanye has research in application mathematics, and he heard Liu Yan En, you can follow the so many things.

Around the people, including Liu Yan En, I only have nodded, my heart also sighed, "I don't want to be Zhao Wei!"

"Is really powerful!"

"This is the level of the award!"

"..."

After Zhao Wei said some data compressed mathematical theory issues, Liu Yan En looked at him to put the light, "Come with me."

He took Zhao Wei to the next small office, then said the goal, "I officially invited you to join the national navigation group in the name of the deputy planner."

"what?"

Zhao Wei suddenly did not adapt, he felt too official, "Don't I do it before?" He refers to the intelligent and automation laboratory, and it is a national navigation system. project.

Liu Yan En shook his head. "I mean, let you stand alone. I said just now, we need a data compression mathematical theory, I want to take your ability, sufficient to take over this project."

"This……"

Zhao Wei is a little hesitant, he is still the first thing to experience such a thing.

Liu Yan, smiled, "You don't have too much pressure, this is not too confidential, data compression is technology, not decryption, even if it is known, it doesn't matter, we just increase the performance of transmitted data, related Techniques can popularize civilians. "

That's it.

Digital compression technology designed by Zhao Wei and Tao Zhexuan, after applying for the patent, there are several international large commercial companies, and they are talking about patent use.

This is actually like communication technology, whether it is, but it is only because of the previous, there is no data compression into a system in China, and he makes him do a related study.

Zhao Wei thought it still agreed.

This is very simple for him.

He only needs to put the mathematics theory of digital compression technology, and you can take the hard sleeve.

Of course.

Because the use is different, mathematical theory also needs a certain correction, and it can be overall.

Anyway, it will not be publicly published, there is no great relationship.

Liu Yan En saw Zhao Wei nodded, and laughed and said. "This project is, I will be responsible, I will report a big project, wait until the completion, do not publish results, will definitely give you the corresponding make up."

"it is good."

Zhao Wei is not particularly careful, what is he cared is not too complicated, affecting his university life.

If it suddenly becomes going to work all day, go to research, there is some unacceptable, in his plan, at least 30 years old, it officially enters the busy work.

Twenty years old ...

Youth!

This is the most beautiful time of life, can't be placed all day.

......

Zhao Wei returned, or I returned with Liu Guangzuo.

On the road.

Liu Guangzu asked, "You pick up the project of Liu's college?"

"you know?"

Zhao Wei was a bit surprised.

Liu Guangzu smiled. "You still think that there is more hidden! Don't listen to the old guy is shocked, domestic compression technology, lack of high-end mathematical theory support, can not be secret in the school, just talking about me, I will know. "

"Oh."

Zhao Wei felt that he was fooled. He thought that there were any hidden projects, the result is what everyone knows.

Liu Guangzuo commented on a sentence, "it is very good."

"Why?" Zhao Wei did not understand, "how much can the project funding?"

Liu Guangzui hesitated, "Now this kind of mathematical theory is not much, this theory is very important, maybe there will be two or three million? The advantage is that the fund will not be pursued, the money is in your hand, It's yours. "

Zhao Wei is a bit surprised, "" So? "

Liu Guangzuo's face is light, "This is the lack of high-end mathematics theory in China, and the systematic application theory is very rare, especially directly to it."

"You want! A small part of the satellite, maybe worth 10 million, can improve the performance of the application mathematics theory, how many million?"

"It makes sense." Zhao Wei toldly.

"Like this kind of completed theory, it is not easy to do it." Liu Guangzuo said, "Liu's governor should find you, and find someone else, so you don't pressure too much, this project The advantage is that no matter what doesn't do, the money is yours. "

"..."

Zhao Wei is really a bit of stress.

Liu University is looking for him to send money, the way to buy a 'future may succeed. He just knew that the original academic community was studying, and there is such a good thing ...
