With the development of new materials science to this day, it has become a modern composite discipline, or interdisciplinary discipline.

For example, no matter which direction of materials science research is engaged in, the most basic mathematics must be mastered. Advanced mathematics is a compulsory course. For example, functional ideas are closely related to magnetic materials research; chemical knowledge must also be mastered. Materials science laboratories are bound to prepare various raw materials through various chemical means; physics is the top priority. After all, if it is a material, it cannot be separated from various tests of its physical properties...

In addition, new materials science also needs to be researched with various advanced instruments, and all data must be calculated and simulated by computers, etc. In short, learning materials may not require you to learn every subject well, but you must understand every subject a little, especially when you reach the research and development stage, you have been in the laboratory for a long time, and the preparation and analysis methods of various materials laboratory have been trained into instinct.

This time, Academician Tan came to the Mathematics Institute. To put it bluntly, he wanted to use the theoretical knowledge of mathematics in the Mathematics Institute to try to solve the possible problems encountered by this carbon nanotube project and give the project team a direction to adjust the experimental plan.

Ning Wei thought so at first, so the task he assigned to March was actually similar. As long as he found out where the problem was and told Senior Brother Zhang that he could submit the job, March's ability was trained.

Ning Wei even considered that he would spend some time studying these data with March every day, trying to find out whether he could find the problem by analyzing these data, and finally verify his ideas with March's ideas, and use this to understand how March, as an artificial intelligence product, thinks and uses mathematical tools to complete such mathematical analysis problems.

However, unexpectedly, March directly skipped the mathematical analysis process and directly built a material mathematical model in an ideal mode through the preparation of laboratory materials. According to the simulation experiment data, the new material mathematical model index, especially the PF value index, directly exceeded the original model by about twice. Not only that, the final measured ZT value, that is, the thermoelectric superiority, is more than three times that of the traditional inorganic p-type tellurium materials mentioned by Senior Brother Zhang.

Yes, the double-walled carbon nanotube sample was given directly through simulation preparation. According to the simulation method given by March, in addition to the previous steps, samples 2 and 3 were fused, and the resulting carbon nanotubes were first dissolved in chlorosulfonic acid to form spin doping. The coating was then filtered and extruded into a coagulant. Finally, the solidified fibers were collected on a rotating drum.

According to the March simulation analysis, the carbon nanotubes in the solution-spinned fibers produced have high aspect ratios, low impurity density, and are highly crystallized, so they have excellent mechanical strength and electrical properties, while maintaining high flexibility.

According to the final report automatically generated in March, the tensile strength of this carbon nanotube material reaches 4.2 ± 0.2 GPa, the electrical performance is σ > 10 milliseconds M?1, and the PF value can reach 14 ± 5 ​​MW M?1. K?2, which are far better than the previously proposed material model.

This is of course a good thing, but what makes Ning Wei’s headache is how he should give this result to Senior Brother Zhang.

Simply put, the purpose of people looking for him is to find out where the problem may be caused through mathematical calculations, and then they reorganized the experiment, but March directly solved the problem through continuous and repeated simulation tests. However, Ning Wei did not guarantee that the simulation test method given by March could really achieve this effect perfectly in a real laboratory environment. After all, systematic simulation tests can completely ignore the various unexpected situations in the laboratory.

In fact, computer simulation books have been widely used in materials science. For example, specialized molecular dynamics simulation software can often explain experimental mechanisms and predict experiments; combined with first-principles software, it can calculate the atomic scale properties of the material; or software such as uspex and Calypso can predict the structure of the material, including the models previously determined by the laboratory, which are likely to be built using this software.

However, the nature of the above computer simulation is essentially different from the simulation calculation method used in March. The former simulates the calculation results based on tasks set by humans, while the latter is close to thinking and solving problems directly from the perspective of humans.

This even made Ning Wei not know how to explain to Senior Brother Zhang how he solved this problem.

Because the idea of ​​March in the original process did not have any reference value, and it can even be understood as a laboratory coincidence. So now there are two choices in front of Ning Wei. One is to introduce the entire mathematical analysis process through the results given in March, and then throw the mathematical analysis process to Senior Brother Zhang, and let them redesign the laboratory preparation plan;

The second is to go directly to the laboratory and ask Senior Brother Zhang to restart the experiment. He gave the entire experimental process and method, and asked the project team to complete the plan given in March again, and then use this method to detect whether the final material model and report obtained in March are correct.

Although the previous method is suspected of taking off his pants and farting, it is relatively reasonable; the latter method depends on Senior Brother Zhang’s trust in him. After all, he restarted the laboratory without reason, and spent money and energy, and wasted a lot of materials. I guess the preparation of these carbon nanomaterials that meet the specifications is not cheap...

"March, March! Are you making a fuss? I'm so useless and organized data, lists, and taught you various mathematical analysis methods. This is how you complete the tasks I assigned you? Can you not be so smart? Although I know you are not an ordinary cat, you are very embarrassed by this! Isn't it good for us to do things honestly according to routines?" Ning Wei muttered to March.

It is said to be a headache, but in fact, there is more joy in my heart. I don’t mention anything else about the joy of growing up in March. This is enough to prove that he has been constantly supplementing the main program of March in the past six months. The understanding of artificial intelligence through existing theories is at least correct in terms of direction. Although the thinking mode in March is very different from that of people, for example, if you cannot fully understand and enrich human emotions, you can only simulate simple emotions, but you can actually solve problems through some human-like thinking modes.

"Meow..." March yelled, then got up, stared at Ning Wei with a wise look for two seconds, twisted his body, pointed his butt at Ning Wei, changed his position and lay on the ground again.

This cat is so courageous!

Ning Wei suddenly got up: "Turn around, or you will throw you back to your laptop now, do you believe it?"

"Meow...meow...ah..." March Wen stomped his hind legs in aggrieved manner, then lay on the ground, moved a little by little, and came back again, at least he could see its small face.

"Tell me, you have only been a few days after you can understand the words, and you have started to feel rebellious? How can you do this?"

Ning Wei complained, but opened the main program of March in his hand. He found the label of fear from the emotions folder. Here he was in charge of all emotions defined as fear, which will automatically record and provide feedback through the anti-encoder autoencoder.

Well, according to the ROC curve feedback from the system, there was a clear fluctuation just now, which probably proved that March did have a perceived emotion about fear, which made Ning Wei very pleased. The child knew that it was a good thing.

However, when he called out the ROC curve for a longer period of time, he found another problem. Under the emotional representation controlled by fear, the impact on March was obviously reduced. He did not remember the first time that he threatened the little March, but at that time the subject program had not been updated and there was no record. When the subject program had just been updated, he would rather make a simple math problem in order to make March calculate a simple math problem, and after seeing the answer it gave, he threatened to reduce the computing resources it could control.

That time the data showed that the peak of fear emotions in March was significantly higher than this time. In other words, the child in March would most likely react to this threat less and less until the end was very likely to be completely useless.

"March, to be honest, are you afraid of me?" Ning Wei asked again.

"Meow..." The kitten licked his paws without him.

Well, indeed, educating children is never a simple job. Ning Wei gave up and continued to fight with March. After looking at the time, it was only 11:30 in the evening. I think Senior Brother Zhang shouldn't have slept yet, so he decided to hand over the choice to this miserable senior brother in materials learning.

If Senior Brother Zhang trusts him enough and is not afraid of wasting him, he is too lazy to take off his pants and fart, restore the entire math process again, and then let the senior brother re-formulate the experimental steps, go to the laboratory again tomorrow, and guide the people in the laboratory to conduct a complete preparation and test; if Senior Brother Zhang dares not take risks, then he will do useless work. Anyway, it won’t take too long to reverse the mathematics with ready-made data.

I think that when I come to this point, Senior Brother Zhang shouldn’t have slept yet...

...

In fact, when the phone ringtone rang, Zhang Yancheng was already asleep.

My nerves were tense for a long time, and today I was thrown out the blame for a while, so he climbed onto the bed early today. It was even more important to make sure that there would be a result there. Let everyone relieve the tension first.

Of course, it does not mean that they can relax after making a result after a week with Ning Wei. Some calculations they should do must be done, and the data still need to be counted. It is impossible to throw the pot to Ning Wei completely and ignore it, but at least they don’t have to stay up late every night and stare at the results.

Then he was awakened by the ringing of the phone in his dream.

According to the general analysis, there is never anything good to receive a call in the middle of the night. After all, this scammer should rest. Even if he doesn’t have a rest, he should enjoy his life. How can he work overtime until this time every day?

So after being awakened, Zhang Yancheng almost bounced up from the bed, and then found the phone and saw the call number. Fortunately, it was not the phone call between the boss and the home.

But at this moment, Ning Wei suddenly called...

With doubts, Zhang Yancheng answered the phone.

"Hey, Mr. Ning, don't say that you have solved the problem?"

"Huh? How did Senior Brother Zhang know? It's almost the same, but it depends on whether you dare to take a gamble."

"A gamble?" Zhang Yancheng was stunned.

"Yes, if you believe me, tomorrow you will prepare the material according to the idea I designed for you, and then you will take it to test it yourself. If you think my idea is not very credible, then wait a few days and I will give you a math report."

"No, Ning Wei, I don't understand what you mean..."

"It's very simple. I know where the problem lies. I'm probably 90% sure. You can give me an email later and I'll send you the new theoretical material model first. If you think you can do it in my way, I'll go to the laboratory tomorrow. If you think it's not reliable, you'll be waiting for two days. It depends on your thoughts."

"Why do I look at your model first?"

"Okay! Then you give me your email address and I'll send it to you."

"Okay, let's chat on WeChat later."

...

After hanging up the phone, Zhang Yancheng felt that he was not sleepy at all.

Although Ning Wei's speed was so fast that he felt unbelievable, he decided to figure out what was going on when he thought that Ning Wei had no reason to tease him, so he immediately made up a piece of clothes and started getting out of bed.

The roommate in the room was still fighting at night. It was not surprising to see Zhang Yancheng answering the phone and not sleeping. Everyone had the same experience, but just took a look and asked, "Have you arranged a task for you again?"

"No, the foreign player you told you had a result."

"Ah? The sharpshooter doesn't have this speed, right?"

"Who knows, let's take a look first." Zhang Yancheng replied with his head down. He had sent his email address to Ning Wei as quickly as possible.

"No, I mean, Lao Zhang, if someone solves the problem for a long time, have you ever thought that this explains a problem?" The roommate put down the book in his hand and said.

Zhang Yancheng raised his head, looked at his roommate and asked, "What's the question?"

"You may not be suitable for materials research! Hahaha..." the roommate said bluntly.

"I..." Zhang Yancheng wanted to refute, but suddenly found that he could not find a reason.

Actually, it makes sense. Ning Wei is studying for a doctorate in mathematics after all. How could he solve the problem that has troubled them for a long time so quickly? Is there any other way to go?

"It's not certain. I didn't say I was 100% sure."

Zhang Yancheng said casually, then turned on the computer, just logged in to the email address, and sent a message on WeChat, with an "OK" expression.

He didn't ask him to wait for a long time and refreshed it, and a new unread email was lying in his email.

Click on the email to download the attachment, open it with the software, and the moment he saw the model results and the report, Zhang Yancheng was stunned.

All my mind is full of ridiculous ideas...

For example, I was satisfied if I wanted to build an anti-aircraft gun, but you gave me a Dongfeng Express suit?
Chapter completed!
