Old man Zhao Manhong attracted everyone's attention to himself with just one sentence.

You must know that during this period of time, through his own participation in the research process that these college students are focused on, from time to time at some critical moments, with his own experience and knowledge accumulation, he can often give some unexpected but logical suggestions. After adopting these suggestions, the students found that such suggestions were simply a guiding light in practice. As soon as there were more hints and discoveries like this, Old Man Zhao Manhong's prestige among these six students suddenly increased. He can be said to be the mentor of these Tsinghua students in this military camp.

And now these students are worried about whether their subject will fail because of a small mistake they made because of their lack of knowledge, at this time, listening to the meaning of Old Man Zhao, it seems that the situation is not as bad as he expected, and now everyone's spirit has been mobilized.

Don't look at the fact that everyone is comforting Liu Yihao at this time, and they want to share the responsibility for this mistake with him, but there really must be a chance to succeed without fail, where will these students let go of such an opportunity.

Among them, Shen Yiyi and Liu Yihao are the most active. Both of them felt that they were responsible for not counting the work of thermal analysis, and they also did not want the project to fail due to their own negligence. If there is a chance to make up for their mistakes and save the problem, they will naturally have a greater sense of mission to save the project.

Liu Yihao even relied on the advantage that he was relatively familiar with Old Man Zhao during this time, and asked: "Old Zhao, Old Zhao, don't sell it, okay?" We all know that you are an experienced old man and should have a better way of doing it than those of us who are students. Tell us what we can do to avoid failing the project because of this heat dissipation problem. ”

Liu Yihao and Shen Yiyi sang and harmonized, the purpose was nothing more than to let Old Man Zhao teach everyone. Because with the knowledge and experience of these two people alone, it is still impossible to understand why Mr. Zhao Manhong is not as worried about the project as everyone else is.

Old Man Zhao was very satisfied when he saw that the big guys were both excited and nervous because of his words. His experience in leading apprentices in the army over the years is that the more difficult problems he encounters, and the more difficult problems seem to be unsolvable, it is often the time when his apprentices are most concentrated. At this time, the concentration of those young people made every word and sentence they said enough to be firmly memorized. Therefore, the educational effect at this time is the best. And now, obviously, for these college students at Tsinghua University, it has also come to such a time when the educational effect is the best.

Now that everyone's enthusiasm has been mobilized, Old Man Zhao will no longer sell Guanzi. He turned back to the young people who were looking at him with eager eyes and said, "You guys, I should applaud you for thinking about the heat dissipation of machinery at this time." Because heat dissipation is indeed an important technical element in the process of firearm design. In the history of the development of weapons in our army, or in the history of human weapons development, there have indeed been many cases of guns jamming, scrapping, or even exploding due to heat dissipation. It can be said that the realization of the need to consider the heat dissipation of firearms is itself an experience gained from the continuous occurrence of accidents. ”

Speaking of this, the old man looked back at Shen Yiyi again and said to her, "This is why not only did I not blame you just now, but I also praised you." Because I know that as a polytechnic student who is not from a military university, naturally you will not be taught the principles of firearms in class. And not only that, but you still seem to be studying electronics. A female college student majoring in electronics, when she came into contact with firearms, thought of a problem that none of the boys in your class who should like to touch guns thought of, even if it was a little late in time, but it didn't make me feel that you were amazing. ”

Old Man Zhao gave Shen Yiyi a high evaluation. Such an evaluation made Shen Yiyi's heart a little embarrassed. Because she knew in her heart that she was not a person with a pure electronic background as the old man imagined. You must know that in her previous life, she was really a female mechanical engineer who was mixed in the military industry. And he has been working in this industry for more than ten years before crossing. So from her own point of view, her mistake this time was really a low-level mistake. It's just that it is impossible for her to clarify this point to the old man on such an occasion, and she has to be ashamed to accept the old man to excuse herself and keep it as a wake-up call for the future.

The old man's words resonated with the boys present. Don't look at Shen Yi, he used his talent and ability to win the recognition of the entire class early on. But in the minds of the boys in the same class, a girl who looks so beautiful will not be easily forgotten because of her outstanding ability. A girl with mediocre appearance and excellent grades may be regarded as a female man by the boys around her; But a girl with outstanding appearance and excellent grades will definitely be regarded as her goddess by the boys around her. Obviously, Shen Yiyi is such a girl.

At this stage, these boys who can personally participate in the transformation of machine guns have a strong love for weapons. And their views on girls are also cultivated from an early age. Because the girls around them have been more like dolls than guns since they were young. This realization continued into their college years. Even in the face of Shen Yiyi, the girl who contacted the army and provided a venue for everyone's research, their understanding has not changed much. They think that Shen Yiyi should also be the kind of girl who doesn't have much interest in firearms. Such a girl can still lead everyone to such a level now, these boys have already given Shen Yiyi a thumbs up in their hearts, where would they be willing to blame her for the mistakes she made when planning the project at that time? This is also one of the reasons why everyone will compete with Liu Yihao to take responsibility for mistakes before.

So at this moment, after the old man Zhao Manhong pointed out the reason why Shen Yiyi was not only faultless, but also meritorious, he immediately got a unanimous response from these boys. Of course, in addition to these boys, Peng Weining, who doesn't seem to have much energy on the side, also thinks so. Although he couldn't say anything about the topic he was studying, just looking at the fact that Shen Yiyi, as a girl, could lead this large group of boys to achieve the current level of this new topic of epoch-making significance in our army, he felt that Shen Yiyi was great enough. Even if the factor of Xi Shi in the eyes of his lover is excluded, Peng Weining, as a soldier, is also envious of such a Shen Yiyi, where is he willing to have some blame. So when he heard that Old Man Zhao personally excused Shen Yiyi, he also accepted Amway as soon as possible.

So among these people present, only Shen Yiyi felt that Old Man Zhao's words made him feel ashamed. However, in the case that he couldn't tell everyone about his shame, Shen Yiyi thought that all he could do was to change the topic as soon as possible.

So Shen Yiyi had to say to Old Man Zhao in a coquettish tone: "Old Zhao, don't divert the topic to me anymore." Do you want to talk about it, what is the reason for the future of our machine gun that will make heat dissipation no longer an obstacle? Don't deliberately downplay the importance of heat dissipation on this topic just to comfort me? ”

Old Man Zhao heard Shen Yiyi's question, and said with a straight expression: "What I said is full of truth. Don't think I'm going to make things up for your comfort and do all that stupid thing. The issue of heat dissipation is not unimportant, but it depends on what gun is most important. If it is a normal rifle, then I can say that you must pay great attention to it, and be careful and careful, because one carelessness may cause the rifle to jam. ”

"But this time we changed it to a machine gun. Compared to a rifle, the heat dissipation problem will not be a big deal in this machine gun. In the end, Mr. Zhao directly revealed his opinion.

However, it is such a point of view, but Shen Yiyi and Liu Yihao are even more confused. Because Old Man Zhao's conclusion is fundamentally different from their own understanding.

Liu Yihao didn't need Shen Yiyi to open his mouth one by one, and asked about Old Man Zhao as soon as possible.

"Isn't that right?! Old Zhao, you said the opposite! Liu Yihao said suspiciously to the old man Zhao Manhong: "You said that the rifle will jam because of heat, then I can understand it." When I usually watch some war movies, I often see the same situation happening. But you said that for rifles, poor heat dissipation will cause failures, why does poor heat dissipation for machine guns not cause failures? That's not right. The machine gun was bursting, and so much heat accumulated in a short period of time far exceeded the scattered heat accumulation of the rifle. Correspondingly, because of the problem of heat dissipation, the chance of machine gun jamming is greater. In some of the war-fighting movies I usually watch, there are not a few machine gun jams. How do you say that this heat dissipation problem of ours is not a problem because it runs into a machine gun? It doesn't make sense! ”

Liu Yihao's question actually represents the voices of all the students present, including Peng Weining. Because the conclusion that Mr. Zhao Manhong said is completely different from everyone's usual understanding of rifles and machine guns. This is a very obvious paradox. So at this moment, Shen Yiyi and Liu Yihao were all staring at the old man Zhao Manhong, wanting to confirm whether the old man was joking by himself just now, or if he was confused at all.

Old man Zhao Manhong saw everyone's doubts about his conclusion. Instead of panicking or anger, he was even more proud. He knew that people had questions about the issue, and that was a testament to the value of his experience. If you want to say that these questions are not reasonable? That certainly makes sense. But was his old man's conclusion wrong? That's also impossible. Because of the equipment you actually encounter in engineering, if you just use the dead knowledge in the books to rigidly apply, you will definitely encounter contradictions.

Old man Zhao Manhong said to everyone unhurriedly: "You can't figure it out, right? Actually, what you think is not wrong, and what I say is not wrong. The reason is that you only know one thing, but you don't know the other. ”

Old Man Zhao then told everyone a key point that he wanted to teach everyone on this knowledge point.

"Actually, you took into account the difference in the calorific value of machine guns and rifles due to the difference in the frequency of operation of different firearms. That's good and commendable. And Liu Yihao, you just mentioned the plots in the war movie, and it's not wrong. Whether it is a rifle or a machine gun, in the early stage of development, there were many failures caused by the heating of the barrel. This cannot be denied. ”

"However, you must know that it has been almost 60 years since the end of the Anti-Japanese War. In the past 60 years, we have had at least four or five generations of equipment development. If you think about it, after all these years of development, won't there be any progress and improvement in today's firearms compared with those original guns at that time? Then you underestimate our military workers too much, right? ”

"The question that you think of, our military workers have long been fully taken into account in the development of firearms from generation to generation. A low-level mistake like missing the heat dissipation factor is something our gunsmiths wouldn't make. Speaking of this, Old Man Zhao once again glanced at Shen Yiyi, who was a little ashamed, and reiterated, "I'll say it again, Shen Yiyi, don't think that you have made a low-level mistake. That is to say that those who specialize in the design of firearms make such mistakes at a low level. And you're just an amateur student, such a mistake is completely normal, and you don't have to feel too embarrassed. ”

Shen Yiyi didn't expect that Old Man Zhao would take the time to notice his embarrassment in the process of enthusiastic commentary, and once again specifically turned around and told himself not to have extra thoughts. After thinking about it, I was really a little flattered. However, I was listening to Mr. Zhao's explanation in front of me, and when I was fascinated, the old man diverted the topic again, and he was very competitive about whether it was good or not. So Shen Yiyi was grateful in his heart, but he couldn't help urging Old Man Zhao to reveal this answer quickly. (To be continued.) )
