Spark

After returning to his residence, Chen Nian began to preview the course content of advanced functional materials according to the plan. After 4 hours, the number of source points increased by 0.1 points again, and the number of source points reached 4.4.

When the time came to 12 o'clock, he went to bed and rested on time, and at 6 o'clock the next day, he got up on time to wash and read a book, and his life was uneventful.

After a week, efficient learning has brought him 1.5 points of origin, which is only 0.8 points away from analyzing high-speed rail technology.

It will take at most three or four days to complete this significant analysis.

It just so happened that Zhang Shuguang had been dragging the four major suppliers for more than a month, almost killing all their patience.

This is the moment when the emotions of the negotiating teams of the two sides are tense to the limit. If they can successfully show their overwhelming cards, then everything will progress very easily.

Thinking of this, a satisfied smile appeared on Chen Nian's face.

It seems that after having the "task manager", my planning is indeed much stronger.

While it's a simple tool on paper right now, the results are evident.

In the future, we have to find a way to move it to an electronic device --- make it a small program to improve ease of use.

It's a pity that the system in my mind doesn't support editing, otherwise, editing directly in the system can guarantee both safety and convenience.

Glancing at the time, Chen Nian left the residence, planning to attend his first physical education class this semester.

Although he said he was very reluctant, but looking at Chen Guo's earnest eyes, he really couldn't refuse

It's a good thing they didn't pick themselves a football basketball or something.

Otherwise, it's a waste of time

After arriving at the assembled indoor gymnasium, Chen Nian saw two familiar figures at a glance.

Li Xiang and Qiao Mai.

The two were standing together and chatting, and they finally seemed to be a little familiar.

But the moment Chen Nian appeared, Qiao Mai's eyes immediately turned around.

"Hey, Chen Nian! Long time no see!"

Really long time no see.

Qiao Mai's schedule is staggered from that of Chen Nian and Li Xiang, and only by chance will they meet for a meal together in the cafeteria.

Although they knew each other early, but to be honest, the opportunities for the two to communicate face to face can be said to be very few.

In addition to the summer vacation, it is indeed a bit strange to meet again.

"long time no see."

Chen Nian came forward to say hello with a smile, thinking to herself, wondering if she could bring any more surprises this time.

It's just three things, if it's so mysterious, Chen Nian still doesn't mind using a little bit of power in his hand to buff himself a little bit.

"I heard that you entered the special class? Congratulations!"

The expression on Qiao Mai's face was very sincere, with envy in it, but absolutely no jealousy.

"Thank you very much, but it's really nothing, it's just that some courses have been advanced."

"That would be great! It's a pity that I didn't get selected, or I could be a classmate with you once."

Chen Nian smiled awkwardly, thinking to himself that it's normal that you weren't selected.

This thing was originally the Radish Hill, and the few students who were actually selected had already been determined internally. Although it seemed that the selection was open, the result would not change in any way.

"It's okay, I heard from the leader that this special class is also experimental, that is, the schedule has changed, and the teachers have not changed much, so there is no need to pursue it."

Qiao Mai nodded thoughtfully, sighed and said:

"It's a matter of saving face. Go out and tell others that you graduated from the special class of Xigong University. How face-saving it is to hear it."

"Forget it, let's not talk about this-hey, what are you doing during the holidays?"

Qiao Mai turned slightly and faced the middle of Chen Nian and Li Xiang, as if he didn't want Li Xiang to feel left out.

Seeing this scene, the corners of Chen Nian's mouth moved slightly, but he didn't answer right away.

"Well, why don't I just play at home, prepare for the new semester's classes, and find some part-time jobs."

Chen Nian couldn't help but rolled his eyes covertly.

To put it lightly, your part-time job is not easy.

Others don't know what Li Xiang is doing, but Chen Nian is well-versed.

In the matter of deceiving and manipulating public opinion, Li Xiang has shown a very high talent. Whether it is the previous negotiation of the Motor Sich factory or the recent EC-130H incident, he actually participated in it.

If he wasn't still in school, his superiors would have made him a full-time member a long time ago.

"How about you, Chen Nian?"

"I'm studying. I went out to play 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 very much hoped that Qiao Mai could say something enlightening and make his source point break through again, but the result disappointed him a bit.

"Basically, I didn't go back either. I followed the school's project and went to the Mechanical and Electrical Institute to study."

Speaking of this, Chen Nian keenly noticed that Qiao Mai's expression was a little weird, so he asked:

"What's wrong? Didn't go well?"

"Uh, I can't say it didn't go well, it's just that it hurts, it's 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 precedent in China. The benchmark is the alignment system of the lithography machine. .”

"Air bearings, have you heard of them? We're working on a design optimization project."

"In the end, I went to the electromechanical office. Guess what, it has already been made."

"That feeling is strange, as if I've been living in someone's shadow"

Chen Nian is embarrassing, to put it bluntly, he has nothing to do with it.

The air bearing was originally one of the results of the fission of the technology he provided before. With the principles and foundations in all aspects perfect, it is normal to develop fast.

But I didn't expect that Qiao Mai's project was cut off directly.

He didn't know what to say, so he had no choice but to say:

"It's okay, you and your brother are both so good, there must be other projects in the future."

"That's right, my brother is going to start working on the suspension system --- the steering suspension of the high-speed rail, which is quite promising."

"."

"...If you believe me, it's best not to go in this direction."

What are you doing!

You want to be charged to death?

The high-speed rail core traction drive technology package that I will analyze in the next step includes the high-speed bogie. If you really want to do it, won’t you crash again?

"Why?"

Qiu Mai asked suspiciously.

"Aren't we negotiating with foreign countries recently? We are going to introduce technology soon. If you are going in this direction now, it is estimated that it will be covered again, which is not worthwhile."

Chen Nian replied solemnly.

"That's okay too."

Hearing his words, Qiao Mai said seriously:

"It's one thing to introduce other people's technology, but it's another thing to digest it into our own technology."

"There is a difference between borrowing someone else's sword and making one's own."

"Besides, we didn't intend to make any particularly big achievements, just use this direction to consolidate what we have learned."

"Don't worry, we know what to do."

Chen Nian sighed.

There is really no way to refute this.

Think about it carefully, Qiao 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 trying their best to explore the frontier direction, but maybe one day, they will be cut off by one of their own analysis results.

But even so, they never gave up, instead they kept challenging new directions.

If Chen Nian was a monster that opened mountains, then they were like worker ants one by one. Although they were not very powerful, they gradually built a magnificent ant nest.

For this, Chen Nian could only admire.

——

But having said that, if unnecessary duplication of labor can be saved, it should be saved.

So he opened his mouth and said:

"No matter what, you should think about it carefully."

"I have a direction, I can give it a 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 China."

Soon, the teacher blew the whistle to call everyone together. After a physical education class, Chen Nian really didn't get any inspiration from Qiao Mai.

It seems that the previous two times were coincidences, and Qiao Mai didn't have any special "luck" attribute.

However, Chen Nian was far from disappointed.

After all, whether it is study or scientific research, it is a matter of step by step and down-to-earth. If it is so easy to opportunistic, will technological development be so difficult?

After physical education class, it was already past 5 o'clock. The three of them went to the cafeteria for dinner together. They had nothing to say all the way. Chen Nian originally planned to go back to his residence and continue to study advanced functional materials. After learning, many practical details mentioned in it have not been verified.

So, he simply hailed a car and ran in the direction of Xicai Research Institute.

His idea is very simple, in fact, it is to touch the equipment and verify what he has learned.

At this moment, in the Xicai Research Institute.

"Is it still not working? Adjust the relative density to about 55%, and try again?"

"It's useless, the relative density of 57% has been tested just now, there is no need to test repeatedly in the same range."

"So what's the problem? Initial temperature? Raw material particle size? Heating rate?"

"I don't know. I don't understand. Has the result of the differential thermal analysis come out?"

"Come out, but it's useless, can't see the problem"

Several researchers discussed in low voices around the failed sample, while Guo Qi couldn't help showing a disappointed look on his face.

Of course, he wasn't disappointed with the young people under him, nor was he disappointed with material science. What he was disappointed with was that his luck was so 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, combustors, and exhaust pipes, and is also useful in electric heating. Components, car spark plugs.

In short, it has a wide range of uses and a great effect.

But now, there is no mature manufacturing method in China.

Generally speaking, SHS technology is used to manufacture molybdenum disilicide, that 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 the influencing factors and synthesis mechanism is not thorough.

Therefore, what they can do is to explore further on the basis of the existing cognitions.

For example, typically, an increase in the relative density of the reactants can promote an increase in the reaction temperature and self-propagation rate.

For another example, the fineness of the powder will affect the reaction process.

But what kind of density, what kind of thickness, and what kind of initial temperature should be used, everyone does not know.

As a result, the progress of trial production has been stuck in the stage of trial and error, unable to move forward.

Since the project was approved, this project has been stuck for 6 months, and so far, there is really no result.

Although this is the normal rhythm of material science research, Guo Qi couldn't help but feel a little unwilling to watch other projects blossom and bear fruit one by one.

Damn it, in the next life I won't be dealing with materials anymore.

This thing is too basic

It's hard work and it's not flattering, so what if you say it nicely, if you can't produce results, who will remember you?

Thinking of this, Guo Qi sighed, walked up to his students, and said:

"Okay, if you can't do it today, you can continue tomorrow. This thing is all about luck."

"Oh, by the way, I will give you a day off tomorrow. Anyone who is free will go up the mountain to see where there is a temple, and ask for it."

Hearing Guo Qi's words, there was a helpless smile on everyone's face.

They all knew that Guo Qi was joking, but they could also see the sadness behind the joke.

How about asking in the temple?

It sounds good, who to ask in the temple?

Taishang Laojun?

Hey, don't tell me, this thing is really a professional counterpart.

It seems that I have to move a statue of Laojun some other day, and if I have nothing to do, I will burn incense and pay respects.

"Boss, is it really a holiday tomorrow? The project is so tight, why don't I let it go, I'm fine."

"I'm fine, I'll come back tomorrow to get ready, and I can do the experiment directly when you come back."

"What are you preparing? Granulating?"

"Pelleting, the raw materials should be prepared, if you can steal some time, just steal some time"

"I think it's useless to do it like this. If you're really lucky, when will it happen?"

As soon as these words came out, everyone fell silent again.

yes.

Although modern materials science does have elements of luck, most of the time, it still depends on theoretical guidance.

Now their problem is that the theory is too weak, so weak that there is basically no way to form a guiding significance.

The only solution is to accumulate data from a large number of experiments and analyze the optimal path through modeling, thereby increasing the probability and reducing the difficulty of "trying luck".

Can only rely on time to boil.

When will it be a head?

There was a neat sigh in the laboratory, and after a while, someone said:

"If only there was a way to get around the flaws of the SHS method."

"Don't take chances, just do it in one step, find some new technology, and cover all the defects."

Hearing this man's words, the 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 all of them will come out."

"Yes, I think the probability of winning 100 million is relatively high"

Everyone teased me sentence by sentence, and the atmosphere finally became a little more relaxed.

As soon as the mood recovered, everyone began to work together to continue the experiment, but at this moment, a voice suddenly sounded at the door of the laboratory:

"There is such a craft."

"The combination of SHS and processing can solve it."

"SHS-pressurization, SHS-squeeze and SHS-squeeze, should all work."
