Rule department scholar

Fortunately, I just went to a meeting on behalf of the laboratory, and I probably wanted him to give some opinions on the error correction code, so I didn't need to spend too much energy.

Just go and take part!

……

The next morning, after Zhao Yi finished his physics class, he walked out of the teaching building and saw a car parked in the aisle.

Liu Guangzuo opened the car window to say hello.

"Just the two of us?" Zhao Yi was a little surprised when he got into the car.

Liu Guangzuo nodded and said, "This meeting is very important, and there are some core things to talk about." What he meant was that some content should be kept secret, and some peripheral people don't need to attend.

Qian Zhijin obviously belongs to the 'peripheral' people.

Zhao Yi felt that he was more 'peripheral', and he asked, "Is it okay for me to participate?"

Liu Guangzuo said, "Actually, it's not that serious. It's just an error correction code. It doesn't affect anything, as long as you don't talk nonsense to the outside world."

"Oh."

Zhao Yi still didn't quite understand.

In fact, he has long been a key talent in the country's name.

Although we haven't done several national projects, but a "three-dimensional tremor waveform map" has made a great contribution.

What Liu Guangzuo knew was that a brand-new encryption program was made using the three-dimensional tremor waveform diagram, and the new encryption program would greatly improve the security of information transmission.

This is obviously the credit of Zhao Yi. A three-dimensional tremor waveform is his stuff. In addition, Zhao Yi submitted very detailed information for the waveform project. Some of the content has not been published publicly, and other mathematicians want to research it. , is also very difficult.

Yanhua University is not far from Capital University of Aeronautics and Astronautics. The car drove into the school gate in less than 10 minutes and drove to a three-story building.

This is the first flight of the computer laboratory building, which also has a small meeting room.

Zhao Yi and Liu Guangzuo got off the car and received a warm reception. They visited the laboratory together and then met Academician Liu Tongen.

Liu Tongen was also very enthusiastic about Zhao Yi. He took Zhao Yi to sit aside, and talked about the three-dimensional tremor waveform diagram, "I have studied the waveform diagram, but the more I study, the more amazed I will be."

"It's really an incredible thing. No wonder many physicists say that the waveform diagram contains the mysteries of the universe. I believe this sentence."

"You are too kind!"

Zhao Yi was a little embarrassed to be praised.

In fact, being praised is also divided into people. If it is an ordinary person, it really doesn't feel special to come here and praise him continuously.

Liu Tongen is different.

academician!

Associate Designer of the National Navigation System!

Both titles sound amazing when put together.

Liu Tongen just praised a few words, which made Zhao Yi feel light and light, and the praise was not empty, it was directly on the point, there are indeed many physicists who are studying three-dimensional tremor waveforms, and think that The waveform diagram contains the mysteries of the universe.

This is still the most basic statement.

Some theoretical physicists with open minds believe that the waveform diagram may be the vibration law of the tiniest particles; The strings are connected, and the waveform diagram can explain the spatial link and the like...

Anyway, Zhao Yi didn't understand either.

Zhao Yi found that Academician Liu Tongen was really a good person, so he talked to Liu Tongen a few more words, and then he was invited to have lunch together.

My mouth is watering after eating this big meal.

Zhao Yi enjoyed a big meal at public expense, and after the meal, he went around the interior of the first flight together with others, and visited several laboratories.

Capital University of Aeronautics and Astronautics' scale and scientific research and development capabilities are indeed stronger than Yanhua University. Some laboratories are located in the country, and they are all top-notch. Their research and development is not only civilian technology, but also participates in military projects.

One of the laboratories is of great significance, which is the key laboratory of metal composite materials.

After introducing it to the visitors, I found out that the laboratory specializes in the research and development of various metal materials. Liu Guangzuo pulled Zhao Yi and whispered, "Not only research and development, but also imitation."

"counterfeit?"

Liu Guangzuo said, "For example, our country wants to manufacture some parts imported from abroad, but it is very difficult. The technology of the parts is not difficult, and the most difficult thing is the material."

They were walking in the workshop next to the laboratory building, which contained various welding equipment, including a small machine tool.

If you just look at the workshop, it looks like a fully equipped factory that produces metal products.

Zhao Yi walked past a test bench and found a dark black thing on it that looked like a metal plate.

"What is this?" he asked.

Someone next to it said, "It's the outer skin sheet, imported from Germany."

"What skin?"

"satellite."

The person who spoke was not very old, and he looked to be in his 30s. Among the many professors, he was considered very young, that is, he was a little older than Zhao Yi.

He said and introduced himself, "Zhang Hongtao, works in the material room."

Another old professor came over and said with a smile, "Zhang Hongtao is a Changjiang scholar, a specially-appointed professor of our university. Although he is young, his knowledge is very solid. His amorphous alloy material project won the national award. The fund focuses on support."

He looked up to see Zhao Yi, and found that he couldn't continue talking.

Most of the people who came to visit the laboratory were not from the first flight. They just walked around the first flight before the meeting. Wherever they went, they would be accompanied by a special person to explain and accompany them. It was also an opportunity to demonstrate the research and development capabilities of the first flight.

When the old professor was talking proudly, he didn't pay much attention to who he was targeting, and suddenly felt embarrassed when he found out that it was Zhao Yi.

Zhang Hongtao is very good?

Yangtze River Scholars?

But in terms of age, he is still more than ten years older than Zhao Yi, so there is no need to compare his achievements. Zhao Yi's achievements have surpassed many top domestic scholars, and he can only compare with those who have won top international awards.

Zhang Hongtao was still far behind.

Zhao Yi listened very seriously, and didn't have the mentality of comparing with Zhang Hongtao. He was just a little curious about putting a plate on the test bench, "Does this material still need to be imported?"

Zhang Hongtao was also a little embarrassed, so he simply took over the topic and said, "This is not a simple plate, it can withstand high temperatures above 1450 degrees, and its electrical conductivity is very good at high temperatures. Physically resistant, very durable…”

He explained carefully, "So far, we have not been able to imitate materials with similar performance, and these parts need to be imported."

"This type of laboratory is for research."

This is counterfeiting and cracking.

It doesn't matter if it's just a single part, but a high-performance material can be used to make many things, which means that there are many parts that need to be imported. It is indeed very useful to understand the composition and manufacturing method of the material.

Some materials perform well enough to be used in other fields as well.

For example, military manufacturing.

Zhao Yi touched the plate with his hand, wanting to see the difference between it and the steel plate, and raised his head to ask, "Is it okay?"

"Of course, it doesn't matter." Zhang Hongtao smiled.

Zhao Yi touched it a few times with his hands, but found no difference. He tried to use the "Law of Cause and Effect" to get the composition of the material.

It's easy.

The periodic table of elements is limited, as long as it has limited content, you can make a judgment. Then he tried to use the "correlation ratio" and got the composition content of each material.

[Check the relationship between the titanium plates in front of you. 】

["Correlation Rate"! 】

[The titanium content of the plate is 73.5%! 】

The content is so high?

Zhao Yi hesitated and said, "This should be a piece of titanium alloy, right?"

Zhang Hongtao didn't take it seriously, "Yes, now we use, whether it's a large aircraft, a satellite probe, or a foreign space shuttle, most of the skins are made of titanium alloy, but the content is other..."

As he spoke, he heard Zhao Yi say, "It also contains aluminum and magnesium, and a small amount of carbon, and even rarer, a small amount of neptunium."

Zhang Hongtao opened his mouth wide in surprise, "How do you know?"

"I'm just guessing."

Zhao Yi smiled, "I read many articles saying that high-end materials require rare metals."

"Are you still interested in chemical materials?"

"Look at it once in a while."

After Zhao Yi finished speaking, he walked away without taking it seriously, and the others didn't take it seriously, thinking he was joking.

The only one he cared about was Zhang Hongtao.

This plate is what he focused on researching. Knowing the content of elements in it, titanium, aluminum, magnesium, and carbon are no problem, but it is the conclusion drawn by his latest research.

The scientific community knows very little about rare metals, and the research results of most countries will not be made public, because rare metals are directly involved in military applications, and it is for this reason that "rare earths" will become national strategic resources.

At present, domestic research on rare metals is still at the initial stage, because without direct understanding, it is very difficult to know what rare metals are contained in a material.

It took Zhang Hongtao a long time to do research, and then relying on various data verifications, he came to the conclusion that 'it is likely to contain neptunium', and made some achievements.

result……

Was it said directly?

Zhang Hongtao was very puzzled. He thought about all kinds of possibilities, but couldn't figure out how Zhao Yi knew, or was it just a random guess as he himself said?

Guess right?

Chapter 265 So there is such a good thing!

Zhang Hongtao couldn't figure out why Zhao Yi was able to accurately import the elements contained in the plates.

'Neptium' is element 93.

There are still very few domestic studies on this kind of elements that rank low on the periodic table, and some added materials are almost all imported from abroad.

As an expert in alloy materials, if you want to directly say that the plate contains neptunium, you can almost only rely on guesswork, because there are several metal elements that can be added to the later part of the periodic table, how do you know it is neptunium?

Zhang Hongtao couldn't figure it out.

At the same time, he didn't feel that Zhao Yu was fooled just now, and that look seemed to confirm that it contained neptunium.

That's no joke.

Zhang Hongtao followed Zhao Yi all the way with doubts. He kept looking for topics to chat with Zhao Yi. The topics were basically related to materials and alloys. He was having tentative conversations.

Zhao Yi kept nodding, hardly speaking.

Zhang Hongtao seems to want him to express some opinions, but Zhao Yi doesn't understand what he said at all. Metal elements do know, and the periodic table of elements can be memorized. What effect, what color and characteristics of a rare metal, etc.

How could this be known!

What Zhang Hongtao said was very professional, and they were all knowledge of metal materials, alloys, etc. Zhao Yi could only listen and nod, as if pretending to understand, but was actually complaining in his heart, "Everything this guy said It’s Chinese, I understand every character, every word, and some even a sentence, but why can’t I understand the whole thing together..."

Zhao Yi said it when he was explaining just now, it was "occasionally looking at" material science, the words have already been said, and he must not understand everything.

So when I can speak I still speak.

For example, some questions with limited answers.

"Does neptunium and aluminum fuse together in a way that makes it more resistant to high temperatures?"

"Can the proportion of carbon element that plays a reconciling role exceed 0.5%?"

"Is it possible to add two rare metal elements to make a more high-temperature resistant and stronger material?"

Zhao Yi's answer is 'yes' and 'no'.

reason?

He won't explain it carefully.

Anyway, the two of them were talking in the form of a chat. It seemed that they were discussing academic issues. In essence, they were just chatting casually, and Zhang Hongtao had no way to delve into it.

After this journey, Zhao Yi really didn't want to stay with Zhang Hongtao anymore.

After leaving the metal material experiment base, he hurried to the side of Liu Guangzuo, and found that Liu Guangzuo was actually quite good.

least……

This guy doesn't bother to talk about metal.

Just now, in order to talk to Zhang Hongtao and show that he has a certain understanding of material science, he spent almost 20 points of energy using "The Law of Cause and Effect" to find the answer to the question.
