As a veteran military worker, Mr. An Zhusheng's understanding of discipline is not indispensable, and he also knows that there is a necessary procedure before such an important project is carried out, which is confidential education, and it must not be known to people who should not know. And he, the leader of the subject, should lead by example, rather than take the lead in violating the rules. So even if he was excited because he suddenly remembered the project he undertook after learning about Shen Yiyi's so-called tolerance optimization theory, a violation was a violation after all.

Old Man An suddenly felt a little depressed. He stood up a little tremblingly, and Shen Yiyi hurriedly wanted to step forward to help him, but he waved him away. The old man walked towards the door, paused when he walked to the door, turned his back to everyone and said, "Old Xiao, that's right, I violated discipline today." I don't defend myself, even if I worry about the project I undertake, but I still have to be held accountable if the confidentiality obligation is not fully complied with. When I returned, I would report to the confidentiality office of the office and accept any punishment that would be given to me. After speaking, Old Man An Zhusheng walked out of the door of Shen Yi's family without looking back. When his figure blended into the sunlight outside the door, Shen Yiyi and Xiao Yizhan were speechless for a while.

Old man Xiao Yizhan watched his old buddy leave without looking back, and he was concerned about the complicated feelings in Old Man An Zhusheng's heart at the moment. He looked at the direction in which his old friend walked away, thought about it, and said to Shen Yiyi: "Classmate Yiyi, you have also seen that Lao An is too anxious in his heart, so sometimes he even forgets the confidentiality discipline that he has been emphasizing. I could feel the eagerness in his heart. Who doesn't look forward to the project they are doing with their kind of work like ours? But over the years, it seems that the equipment we have researched ourselves can only reach such a level. No matter how hard you try, the performance indicators will never go up. It's like the set of drawings you have in your hand, before the finished product is made. Whether it is Lao An or myself, no one would have expected that the real prototype would have such performance. So, when I know that this important improvement point you proposed has the potential to make a big step forward in the performance of the equipment, don't talk about him, even I have an impulse. I would like you to join us in our current research project. ”

Shen Yiyi looked at Old Man Xiao's heavy heart, and he was still very moved by the spirit of the older generation of scientific research workers who devoted themselves to their work. To be honest, the older generation of scientific research workers like An Zhusheng and Xiao Yizhan may be very famous in China if they want to be famous, but if they want to talk about profits, none of them have made a lot of money because of the knowledge they have mastered. Although they are retired at the same level, they can also enjoy some courtesies in their own units after leaving their jobs, and they can also be properly taken care of in life. But let's be honest, what they give is not proportional to what they get. But most of them have no complaints. Such a spirit of willingly dedicating oneself to the cause of the country and the nation has almost disappeared from people twenty years later.

"Elder Xiao, I understand what you said. But did An Lao violate the law just now? So what do I do? Did I hear something I shouldn't have heard? Shen Yiyi was a little worried about the secrecy standards of this era. She wondered if she would get herself in trouble because she heard something she shouldn't have heard.

Xiao Yizhan saw a trace of worry on Shen Yi's face, and he didn't know if Shen Yi was worried about whether the secrecy management in this era would be too tight at the beginning, and he thought about it in his heart, and he was right. This little girl may have been frightened by what Lao Antou and herself said just now. In fact, it is really far-fetched to characterize Lao Antou's words as leaks. So Old Man Xiao temporarily let go of his feelings about An Zhusheng's gaffe. turned to comfort Shen Yiyi: "Lao Antou spoke a little too fast just now, but you don't have to worry." I guess he'll report to them when he goes back, and it shouldn't have anything to do with you. So you don't have to worry too much about one by one. ”

After thinking about it for a while, he said, "But, Yiyi, if you have time." I hope you can sort out the things you just told us about what tolerance accumulation and optimization are, and give us a detailed lesson. Seriously, I'm really curious where you learned so many novelties. Over the years, Lao An and I have read a lot of books, big and small. But I've never seen anything new from you. ”

When Shen Yiyi began to explain to them, he had already imagined in his heart that others might ask such a question. And she had already thought of a standard answer to deal with this kind of question and cover up the fact that she had passed through rebirth. So she replied confidently, "Nothing new." I think that if you read more books and think more, you will naturally gain something. ”

This sentence is the same as not saying it, but an old expert like Xiao Yizhan listens to it, but it is very in line with his view of the world. Isn't it, thinking a lot, what a simple truth. It's just that no one knows the way, not everyone can think about it. Invisibly, Old Man Xiao recognized Shen Yiyi's genius and magical girl's identity.

The old man had already gone back to the unit to report the gaffe, and Shen Yiyi also promised that once he was free, he would take the time to sort out the tolerance theory that made the two old men equally curious, and the old man Xiao Yizhan no longer stayed in Shen Yi's family, and went home by himself, leaving only Shen Yiyi's classmates at home by himself, continuing to prepare for his winter vacation homework, while waiting for his parents to come home.

After writing for a while, Shen Yiyi put down his pen one by one and remembered today's situation. She felt that when it came to Old Man An's gaffe, it was more due to Old Man An's dedicated attitude. Shen Yiyi also clearly knew that it was not only old scientific workers like Xiao Lao and An Lao, but also the old workers of Luo Yu's grandfather's generation, and their dedication to their jobs would not be matched by young people in the future. Not to mention that a skilled worker above level 7 like Grandpa Luo has basically been lost in his generation. China's hierarchical mechanic system has completely disappeared with the restructuring of state-owned enterprises that is about to sweep the country in Northeast China. In the future, workers will no longer be a technical position, but will be purely regarded by enterprises as fluid lines or a mechanical arm in front of the machine that does not need to use the brain and only needs mechanical labor. The working class claims to be the leading class of the republic, but paradoxically, in the new century, no one thinks that the worker is a profession to be proud of.

Of course, Shen Yiyi does not think that workers as a profession should sink. In fact, she also believes that the market economy has an invisible hand that is ready to move at any time to correct this irrational phenomenon. Around the year or so that she had traveled back, there had been an auto-adjusting signal released. On the one hand, college students who graduated at that time complained that they couldn't find a job; On the other hand, some positions of skilled workers with high technical requirements are still unable to recruit people with an annual salary of 200,000 yuan. Therefore, from the perspective of economic development, the temporary development deviation will naturally return to the right path with the passage of time, but she is embarrassed to think of the loss of skills and skills paid by the country and the nation.

Similarly, she completely understood the reason why Old Man An lost his temper and Old Man Xiao sighed just now. To put it bluntly, the project that Mr. An said is not difficult to guess at all. Thinking about what the 606 Institute does, and what kind of scientific research tasks will be carried out to reach the 606 Institute, it is naturally very clear. Moreover, the heart disease problem in China's aviation industry has not been broken through until the first decade of the new century has passed. It can be seen that the stagnation of this skill level must become an eternal pain in the hearts of people like Mr. An who have been engaged in engines all his life. That's why Mr. Ann blurted out that he wanted to involve himself in the performance improvement of his project.

However, she also clearly believes that this project must be secret. So for an unclassified person like her, the likelihood of participating in the research is zero. In fact, according to the confidentiality regulations, even if the name of a non-confidential person like her is mentioned, in the eyes of some people with a strong sense of confidentiality, it already belongs to the category of leakage. This is also the reason why Mr. An admitted that he had violated the rules and discipline just now, and said that he would ask for punishment. The string of confidentiality and security must be tightened at all times, which is a sentence that Shen Yiyi of later generations will be reminded of when he receives confidentiality fees when he is mixed in a large state-owned enterprise. Therefore, since Shen Yiyi's current student status, it is impossible to enter the 606 Institute to work, and it is impossible to become a researcher who is included in the confidentiality management, so of course it is impossible for him to join the research of the old man's topic.

However, she Shen Yiyi also has a patriotic heart, although this patriotic heart is also mixed with some utilitarian considerations, but it does not affect her desire to contribute to my country's engine industry. Therefore, she has secretly made up her mind to donate the set of tolerance theories she has mastered. Of course, there are still ways to donate. However, she believes that the personalities of the old man Xiao Yizhan and the old man An Zhusheng will not let herself suffer.

If we had our own set of tolerance theories, the researchers at the 606 Institute would be able to apply them to the research work of the current research projects, and the performance of the prototype would be improved, right? Shen Yiyi thought secretly.

For aero engines, the more important basic research is materials science, and researchers often cannot find a reliable material that can work stably in high temperature and harsh environments, which is the primary obstacle hindering the progress of human aviation technology. Of course, for China, processing technology and design shortcomings are also one of the important factors. Although its own tolerance theory cannot solve the problem of materials, it should be able to maximize the potential of existing materials through the optimization of process and design. Therefore, Shen Yiyi began to have expectations for Mr. An's future achievements on his projects. (To be continued......)
