From Almighty Scholar to Chief Scientist

However, the diffractometer will not hurt people, and even if an X-lithography machine is made in the future, there is no need to worry about hurting the staff.

Because the X-rays in the CT room are originally used to irradiate people, the staff will inevitably be injured by those radiations when they are working.

The X-rays in the diffractometer are used to irradiate objects, so protective measures can be taken. Only a 1mm lead plate is needed to reduce the radiation to a level lower than that of mobile phones.

Therefore, there is no need to worry about the harm that X-ray lithography may cause to people. In fact, although extreme ultraviolet light is called ultraviolet light, it can actually be called soft X-rays. Protection, you don't have to worry about it at all.

So these researchers are not worried about being radiated while sitting next to them.

They looked at Lin Xiao over there, and were very curious about what he was going to do, so they all asked, "Professor Lin, what are we doing now? Are we going to start designing crystal structures?"

Lin Xiao, who was sitting on another computer, smiled and said, "Yes."

The trainee researchers were suddenly surprised: "Professor Lin, have you already clarified the law and reason of diffraction?"

"Basically." Lin Xiao replied, "So our job now is to verify my results."

The trainee researchers were even more amazed.

Professor Lin said that he found the law and reason of diffraction, can they say "impossible, this is absolutely impossible"?

They're not as sharp yet.

Of course, they also want to know what the law and reason are. Has Lin Xiao worked out the thesis yet?

However, Lin Xiao did not disclose it to them for the time being. Since he knows that this thing may be related to their domestic military development, he will first produce the paper and send it to relevant departments, such as those who specialize in military technology. Research institutions, let them see if there is any need for confidentiality.

Of course, after his theories are posted, there is no need to worry about whether they will be stolen. They are all recorded. The background is amazing?

Just think about who the senior party officials of their research institute are. The senior party officials of the Dingguang Research Institute have no one at their head, only the people.

Time passed quickly, and the X-ray diffraction scan took a long time, so they had been waiting, and Lin Xiao had been inputting a program before, and now, he finally completed the program.

This program is a program for simulating crystal X-ray diffraction based on the principle of Lin's wave coherent superposition equation.

As long as the wavelength, intensity, and incident angle range of X-rays are input, and then the crystal structure and refractive index of the crystal are input, the diffraction image of X-rays when penetrating the crystal can be obtained.

Afterwards, he entered various data of the crystal being detected in the X-ray diffractometer, and then pressed the Enter key.

Then, an XRD spectrum appeared in front of him.

The XRD pattern refers to the X-ray diffraction pattern, mainly wavy lines with abruptly rising peaks.

Through the analysis and calculation of these wavy lines, the crystal structure, texture and stress can be clarified.

And at this moment, the intern researchers over there suddenly shouted: "It's done! Professor Lin!"

"The analysis results are out!"

It turned out that the X-ray diffractometer scan was completed.

"Professor Lin, I want to send you the picture... um? When did you get the picture, Professor Lin?"

When an intern researcher turned his head to ask Lin Xiao, he suddenly discovered that an XRD pattern had appeared on his computer screen, wasn't it very similar to the analysis result in front of them?

Or should I say, exactly the same.

However, he has always been connected to the computer of the X-ray diffractometer. As a result, he hadn't sent it to Lin Xiao just after it came out. How could Lin Xiao have it?

Lin Xiao smiled: "This is the image calculated by my simulation."

Everyone present was stunned: "Analog computing?"

"Yes."

Lin Xiao nodded, smiled and spread his hands and said: "Didn't I tell you just now, I found the law and reason of interference and diffraction, so according to my results, as long as we know the internal structure of the crystal in advance, we can know its XRD pattern."

The people present were stunned when they heard this, but they hadn't reacted yet.

After knowing the crystal structure, can you then know its XRD pattern?

"Professor Lin, if we want to know the crystal structure, don't we have to analyze its XRD pattern first? If we all know the crystal structure, why bother with its XRD pattern?"

Lin Xiao smiled and said, "Everyone, don't forget our purpose, we want to build a crystal that can magnify and shrink X-rays!"

These researchers reacted immediately.

Yup!

The purpose of their research is not to analyze the crystal structure. The crystal structure they used was known before.

And the purpose of their experiment this time is to help Lin Xiao verify his results!

and so……

This result...

"Professor Lin, is the verification successful?"

Their eyes lit up, and they looked at Lin Xiao excitedly.

"Yes, it succeeded." Lin Xiao smiled slightly. "Of course, only the first crystal was successful. We still need to continue to verify more crystals. In addition, confirm the error between my calculation results and your actual scanning results."

"it is good!"

The researchers immediately went into action again.

There is a certain error between the actual XRD pattern of the first crystal and the XRD pattern calculated by Lin Xiao's simulation.

However, Lin Xiao believes that this error comes from the error of their X-ray diffraction machine itself.

And his calculation results are more accurate.

The calculation results are more accurate than the experimental results, and it does not exist. For example, when the industry studies turbulence problems, it often uses DNS and direct numerical simulation to solve NS equations. There are even a large number of examples that show that this calculation The reliability of the result exceeds that of the experiment. Of course, because the well-posedness of the solution of the NS equation has not yet been proved, it will still lead to the existence of errors.

Next, they went through several experiments to verify, without exception, they all proved that Lin Xiao's conclusion was correct, and although there were errors, these errors were all caused by the precision of the instrument itself.

All in all, Lin Xiao can officially announce——

He mastered interference and diffraction!

Chapter 252 Excited Ma Gaoliang

After completing the verification of the theory, the next step is naturally to build the crystal.

Although with the help of wave coherent superposition equations, there are still certain complications in building a crystal structure, because it needs to consider many situations.

The first is the X-ray wavelength.

The wavelength of X-rays is about 0.1nm-10nm, so how to choose a suitable wavelength is also a problem.

After choosing the wavelength of X-rays, you need to choose what material the crystal should be made of, whether it is silicon, polymer, or something else. Different materials determine different costs, and of course, also determine the final performance.

All of these require some calculation and discussion.

Of course, these things only need to be calculated on the computer, and it does not require much economic cost, only time cost.

For these problems, Lin Xiao needs to find a researcher who studies materials again.

Of course, Lin Xiao was not in a hurry to deal with these things, but first sorted out the papers on Lin's wave coherent superposition equations, and attached what he thought Lin's wave coherent superposition equations would be useful for national defense. business can play a role.

The wave coherent superposition equations are different from the titanium bonding mechanism he discovered at the beginning. The former can be directly used in the research of national defense, probably like the role of Qian Xuesen's ballistics, while the latter still needs further theoretical research before it can be used. To applied science, it's like the theory of relativity.

So he attaches great importance to the wave coherent superposition equation. As for the honor that publishing this paper will bring to him, he doesn't care. His honor is enough. Compared with the needs of the country, these things can be done. Back a little bit.

In this way, it took a few days to finish sorting out the thesis, and then he called Ma Gaoliang.

Of course, it is best to ask Ma Gaoliang to handle this matter.

"Director Ma, are you free now?"

"Are you free? Is there anything Professor Lin can do?"

"I need to trouble you with something, old place, what time do you think is the best time to go today?"

Ma Gaoliang was taken aback for a moment, then his eyes lit up.

Lin Xiao took the initiative to meet him. Is this the rhythm of good things?

I remember that the last time Lin Xiao took the initiative to approach him, he was asking him to help apply for the polishing disc material. Now, the new polishing disc has directly helped their silicon wafer production speed catch up with the world's top.

Now take the initiative to find him, is there any good thing?

So he said immediately: "Yes, yes, of course, right now, what do you think?"

Originally, he had a departmental meeting later, but compared to meeting Lin Xiao, there was no need to hold this meeting.

"Okay, let's do it now."

"Okay! The old place, I'll be right there, by the way," Ma Gaoliang said, "Professor Lin, is there any good news, please tell me about it?"

Lin Xiao smiled and said, "Yes, you can just look forward to it later."

"okay."

After talking over there, Lin Xiao heard Ma Gaoliang calling his secretary to prepare the car.

Shaking his head with a smile.

Afterwards, he said no more, took the hard copy of his thesis, and left here, heading to the old place, which is the tea restaurant with an official background.

……

Duet of Flowers.

It's the name of the tea restaurant.

In the corner of the restaurant, Lin Xiao and Ma Gaoliang sat facing each other, with a pot of Dahongpao, ordering a few more meals by the way.

Lin Xiao directly handed the portfolio to Ma Gaoliang, and said, "This is it."

Ma Gaoliang quickly took the file bag and asked, "What's inside?"

"A formula."

Lin Xiao replied with a smile.

Ma Gaoliang thought about it in his mind, and finally asked cautiously: "Could it be the solution to the P=NP problem?"

Lin Xiao: "...Why do you think this is it?"

"If this is solved, it will be of great help to us in cracking those foreign encryption systems. You should know that if P=NP is solved, our existing encryption will basically cease to exist, right? Unless we come up with quantum encryption."

Lin Xiao spread his hands helplessly and said: "Well, your imagination is very rich, but unfortunately it is not."

"That is to prove the existence and smoothness of the solution of N-S equation?"

"No." Lin Xiao said, "Okay, Director Ma, my recent research is on semiconductors and lithography machines, not the things you mentioned."

"The formula I developed is strictly speaking a system of equations, which can accelerate our research on lithography machines extremely quickly."

"In addition, military researchers may also want to see my equations very much.".

Ma Gaoliang's eyes suddenly brightened: "Military? You mean this equation can..."

"Yes, so I hope you will give this information to military researchers." Lin Xiao said, "I personally think that this equation system is of great help to our military technology, so do I need to use This result is kept secret and depends on your opinions.”

Hearing what Lin Xiao said, Ma Gaoliang was immediately in awe: "I see, thank you, Professor Lin."

Lin Xiao smiled and waved his hands, "There is nothing to thank, I hope to hear the news that the country needs my equation set."

"it is good."

Ma Gaoliang nodded, accepted the file bag, and then asked: "Then, which major is best to give this thing to?"

Lin Xiao thought for a while and said, "Those who study waves, those who engage in radar, and those who engage in stealth coating materials are all fine."

"Stealth coating material?"

Ma Gaoliang's eyes stared suddenly.

Could it be that Lin Xiao's research also contributes to the research and development of stealth coating materials?

Stealth coating materials are definitely one of the most important materials in national defense technology.

It is so famous that it makes countless fans of the Hua Guojun think about how a returned B2 bomber can be hailed as a ghost in the air because of its strong stealth effect and various stealth coatings on it, which makes it fly During the process, it will be difficult for the radar to achieve early warning, and when the human eye can see it, it has completed the bombing of the target.

Another example is Huaguo's J-[-]. During the research and development process, the first thing that baffled the designers was the engine, and the second was the stealth material.

The engine allows the J-[-] to achieve the maneuverability of the fifth-generation fighter, while the stealth material gives the J-[-] the stealth performance required by the fifth-generation fighter.

So when Ma Gaoliang heard about the stealth coating material, his whole body became sensitive as if he had been scratched to an itchy spot.

Seeing Ma Gaoliang like this, Lin Xiao smiled and said, "Yes, it is the invisibility material. I won't tell you the details. If you are interested, you can look back for yourself."

"Forget it, I'm afraid I can't understand it." Ma Gaoliang waved his hands again and again: "I don't even know what P=NP and what is the Navier-Stokes equation, but I know the use of solving these problems."
