After returning to his residence, Chen Nian began to preview the course content of advanced functional materials as planned. After 4 hours, the number of source points increased by 0.1 points again, reaching 4.4.
When the time came to 12 o'clock, he went to bed on time to rest. At 6 o'clock the next day, he got up on time to wash up and read a book. His life was uneventful.
After a week, efficient learning brought him 1.5 points of origin, and he was only 0.8 points away from analyzing high-speed rail technology.
It only takes three or four days at most to complete this significant analysis.
It just so happened that Zhang Shuguang had delayed the four major suppliers for more than a month, almost wearing out all their patience.
This is the moment when the emotions of the negotiation teams on both sides are stretched to the limit. If they can successfully come up with an overwhelming trump card, everything will progress extremely easily.
Thinking of this, a satisfied smile appeared on Chen Nian's face.
It seems that after having the "Task Manager", my planning ability is indeed much stronger.
Although it is just a simple tool on paper now, the effect is obvious.
In the future, I have to find a way to move it to electronic devices - make it into a small program to improve the ease of use.
Unfortunately, the system in my mind does not support editing. Otherwise, if I edit directly in the system, both safety and convenience would be guaranteed.
After taking a look at the time, Chen Nian left his residence and planned to take his first physical education class this semester.
Although he was very reluctant, looking at Chen Guo's eager eyes, he really couldn't refuse.
Fortunately, they didn't choose football or basketball for themselves.
Otherwise, it would be a lot of effort
After arriving at the indoor gymnasium where they were gathering, Chen Nian saw two familiar figures at a glance.
Li Xiang and Qiu Mai.
The two of them were standing together chatting, and they finally looked a little familiar.
But the first time Chen Nian appeared, Qiu Mai's eyes immediately turned around.
"Hey, Chen Nian! Long time no see!"
It's been a long time indeed.
Qiu Mai's schedule is staggered with that of Chen Nian and Li Xiang, and only by chance would they meet and have a meal together in the cafeteria.
Although they met early, the opportunities for the two of them to communicate face to face can be said to be very few.
After taking a summer vacation, it was indeed a bit strange to meet again.
"long time no see."
Chen Nian smiled and stepped forward to say hello, thinking to himself whether she could bring any more surprises this time.
It's only three things. If it's really that mysterious, Chen Nian still doesn't mind using some of his power to give himself some buffs.
"I heard that you entered the special class? Congratulations!"
The look on Qiu Mai's face was very sincere, with envy in it, but absolutely no jealousy.
"Thank you very much. It's actually nothing. I just moved some courses forward."
"That's great! It's a pity that I didn't choose. Otherwise, I could be your classmate again."
Chen Nian smiled awkwardly and said to himself that it was normal for you not to choose.
This thing is originally a carrot hill, and the few students who are actually selected have already been decided internally. Although it seems to be an open selection, in fact, the results will not change.
"It's okay. I heard from the leader that this special class is also experimental in nature. That means the class schedule has changed, but the teachers have not changed much. There is no need to pursue it."
Qiu Mai nodded thoughtfully, sighed and said:
"It's just about saving face. When you go out and tell others that you are a graduate of the special class of NPU, it's very face-saving."
"Forget it, let's not talk about this--hey, what are you busy with during the holidays?"
Qiu Mai turned slightly towards the middle of Chen Nian and Li Xiang, as if he didn't want Li Xiang to feel left out.
Seeing this scene, Chen Nian's mouth moved slightly, but he did not answer immediately.
"Well, I'm not just playing at home. I'm previewing my classes for the new semester and looking for a part-time job."
Chen Nian couldn't help but rolled his eyes secretly.
To put it lightly, your part-time job is not easy.
No one else knows what Li Xiang is doing, but Chen Nian is a well-known person.
Li Xiang has shown great talent in deceiving and manipulating public opinion. Whether it was the previous negotiations with the Motor Sich factory or the recent EC-130H incident, he was actually involved.
If he hadn't been in school, his superiors would have directly promoted him to a full-time job.
"How about you, Chen Nian?"
"I'm studying. I went out for fun some time ago, and then I didn't go home. I previewed some special classes in advance. What about you?"
Chen Nian asked expectantly.
He really hoped that Qiu Mai could say something enlightening and make his origin point achieve another breakthrough, but the result left him a little disappointed.
"Almost, I didn't go back. I followed the school project to study at the Institute of Mechanical and Electrical Engineering."
When he said this, Chen Nian keenly noticed that Qiu Mai's expression was a little strange, so he asked:
"What's wrong? It's not going well?"
"Well, I can't say it didn't go well. Even if it was harmful, it was nothing."
"Didn't I tell you before that I was working on a hydraulic and bearing project? I prepared a new design with my brother. It was quite advanced. There is no domestic precedent. The benchmark is the alignment system of the photolithography machine. .”
"Air bearings, have you heard of them? We are doing optimization design projects."
"As a result, I went to the mechanical and electrical institute and guess what, it has already been made."
"It's such a strange feeling, like I've been living in someone's shadow."
Chen Nian was embarrassed. To put it bluntly, this matter had nothing to do with him.
Air bearings are originally one of the results of the fission of the technology he provided before. With all the principles and foundations in place, it is normal for it to develop quickly.
But I didn't expect that Qiu Mai's project was cut off directly.
He didn't know what to say, so he had to say:
"It's okay. You and your brother are both so good. There will definitely be other projects in the future."
"That's right, my brother is going to start making suspension systems - the steering suspension of high-speed rail, it's quite promising."
"."
".If you believe me, it's best not to go in this direction."
What are you doing!
Do you want to be charged to death?
The core traction transmission technology package of high-speed rail that I will analyze next includes high-speed bogies. If you really want to do it, won't you crash again?
"Why?"
Qiu Mai asked doubtfully.
"Aren't we negotiating with foreign countries recently? We are about to introduce technology. If you go in this direction now, it will probably be covered again, which is not cost-effective."
Chen Nian replied seriously.
"That's okay."
After hearing his words, Qiu Mai said seriously:
"It is one thing to introduce other people's technology, but it is another thing to digest it into our own technology."
"There is a difference between borrowing someone else's sword and making your own sword."
"Besides, we don't plan to make any particularly big results. We just use this direction to consolidate what we have learned."
"Don't worry, we know what's going on."
Chen Nian sighed.
There's really no way to refute this.
If you think about it carefully, Qiu Mai is definitely not the only one who "lives in the shadow of others".
In China, countless researchers are covered in their own shadow.
They are working hard to explore the frontier, but maybe one day they will be intercepted by one of their own analysis results.
But even so, they never gave up, but continued to challenge new directions.
If Chen Nian is a giant beast that created a mountain, then they are like worker ants one by one. Although they are not very powerful, they gradually build a spectacular ant nest.
Chen Nian could only admire this.
——
But having said that, if you can save unnecessary duplication of work, you should still save it.
So, he opened his mouth and said:
"No matter what, you should think about it carefully."
"I do have a direction that I can try."
"You know, there is an important hydraulic system on the aircraft carrier, which is the hydraulic system of the arresting cable. There is still relatively little research in the country."
Soon, the teacher blew the whistle for everyone to gather. After the physical education class, Chen Nian really didn't get any inspiration from Qiu Mai.
It seems that the previous two times were coincidences, and Qiu Mai did not have any special "luck" attributes.
However, Chen Nian cannot be said to be disappointed.
After all, whether it is learning or scientific research, it is something that must be done step by step and down-to-earth. If it is so easy to take advantage of opportunities, will technological development be so difficult?
After the physical education class, it was already past 5 o'clock. The three of them went to the cafeteria to eat together. They were silent all the way. Chen Nian originally planned to go back to his residence and continue to study advanced functional materials, but then he thought about it and decided to take the silicon material metallurgy course. I have finished learning, but many of the practical details mentioned in it have not yet been verified.
So, he simply called a car and headed in the direction of the Western Materials Research Institute.
His idea is very simple. In fact, he just wants to touch the equipment and verify what he has learned.
At this moment, in the Western Material Research Institute.
"Still not working? Adjust the relative density to about 55% and try again?"
"It's useless. We have just tested the relative density of 57%. There is no need to test the same range repeatedly."
"What exactly is the problem? Initial temperature? Raw material particle size? Heating rate?"
"I don't know. I don't understand. Have the results of differential thermal analysis come out?"
"It came out, but it's of no use. I can't see the problem."
Several researchers were discussing in low voices around the failed prototype, while Guo Qi couldn't help but have a look of disappointment on his face.
Of course, he is not disappointed with the young people under his command, nor is he disappointed with materials science. What he is disappointed with is that his luck is really bad!
This time they plan to trial-produce molybdenum disilicide, which is a high-temperature anti-oxidation coating widely used in the aviation field. It is generally used in the sealing of turbine engine components, burners, and tail nozzles, and is also used in electric heating. components, automotive spark plugs.
In short, it has a wide range of uses and great effects.
But now, there is no mature manufacturing method in China.
Generally speaking, SHS technology is used to manufacture molybdenum disilicide, which is self-propagating high-temperature synthesis technology.
But the problem is that human exploration of this technology is still relatively limited, and the understanding of influencing factors and synthesis mechanisms is not thorough.
Therefore, what they can do is to further explore based on several existing cognitions.
For example, typically, an increase in the relative density of reactants can promote an increase in reaction temperature and self-propagation rate.
For another example, the thickness of the powder will affect the reaction process.
But no one knows exactly what density, thickness, and initial temperature to use.
This also resulted in the trial production progress being stuck in the trial and error stage and unable to move forward.
This project has been stuck for six months since its inception, and so far, there has really been no results.
Although this is the normal rhythm of materials science research, Guo Qi can't help but feel a little unwilling as he watches other projects come to fruition one after another.
Damn it, I won’t do anything with materials in my next life.
This thing is too basic.
It's hard work and thankless, no matter how nice you say it, if you can't produce results, who will remember you?
Thinking of this, Guo Qi sighed, walked to his students, and said:
"Okay, if it doesn't work today, just continue tomorrow. This thing is all about luck."
"Oh, by the way, I'll give you a day off tomorrow. If anyone is okay, go up the mountain and see where there is a temple. Go and ask for help."
Hearing Guo Qi's words, everyone had a helpless smile on their faces.
They all knew that Guo Qi was joking, but they could also see the sadness behind the joke.
Why don't you go to the temple to pray?
It sounds nice, but who can I go to the temple to ask for?
Taishang Laojun?
Hey, don't tell me, this thing is really professional.
It seems that I will have to bring a statue of Laojun here some other day. If I have nothing to do, I will burn some incense and pay my respects.
"Boss, are you really going to have a day off tomorrow? The project is so tight, so why don't I give it up? I have nothing to do."
"I have nothing to do. I'll come back tomorrow to get ready. When you come back, you can start doing experiments directly."
"What are you preparing for? Pelleting?"
"For granulation, the raw materials must be prepared. If you can steal some time, just steal some time."
"I feel like this is useless. If I really try my luck, when will it happen?"
As soon as these words came out, everyone fell silent again.
yes.
Although modern materials science does involve luck, most of the time, it still relies on theoretical guidance.
Their problem now is that the theory is too weak, so weak that it basically cannot form any guiding significance.
The only solution is to accumulate data through a large number of experiments and analyze the best path through modeling, thereby increasing the probability and reducing the difficulty of "trying your luck".
It can only be overcome by time.
How long will it last?
There were neat sighs in the laboratory, and after a moment, someone said:
"It would be great if there was a way to circumvent the shortcomings of the SHS method."
"Don't push your luck, just get it right in one step, find some new process, and cover all the defects."
Hearing this man's words, others couldn't help but roll their eyes.
"Why don't you want to win 100 million in the lottery? When the time comes, we will hire a bunch of people to do experiments, and they will be reckless."
"Yes, I think the probability of winning 100 million is relatively high."
Everyone was making fun of each other, and the atmosphere finally became more relaxed.
As soon as their emotions recovered, everyone began to prepare and continue the experiment. But at this moment, a voice suddenly sounded at the door of the laboratory:
"There is such craftsmanship."
"SHS can be solved by combining it with processing."
"SHS-pressurization, SHS-extrusion and SHS-extrusion methods should all work."
