Originally, he found that the level of bad hardware in the laboratory was not enough to take over this big project, and now he is facing backwardness in materials, Professor Liu also feels all kinds of powerlessness, maybe this project is really not related to him. Vertices are updated the fastest

"After you say this, I found that there are really a lot of problems with this project, there seems to be no material in China, and international procurement is even more impossible, I think this project is not suitable for the project to be proposed now, or immediately suggested, to see if the above can solve the material problem first, we will talk about the follow-up process. ”

After saying this, in Wang Zhengguo's surprised eyes, Professor Liu really took out the manuscript paper from the drawer and began to write letters.

Maybe it's not like Professor Liu has something to write about himself, so today's experiment will definitely be impossible, and his assistant work is really unfavorable, so he sat like this on the first day, and even if he had nothing to do, he definitely couldn't run out to do his own private affairs. Of course, at this time, he really didn't have any personal matters to do, and it didn't matter if he "wasted" time with the professor.

I have to say that the actions of this older generation of intellectuals are indeed very quick, and in just one morning, they sorted out all the relevant problems, and after making sure that there was no problem, they directly sent Wang Zhengguo today's first errand task: sending letters.

"I've written all the relevant questions here, and you can help me send the letter when you go out in the afternoon. I don't think there should be anyone in other units in China to take this project, and now the civilian resin materials of the entire industry have not yet been able to meet the required standards for precision optical glass, as for military units, I don't know much about this, but if military units have this ability, they should have done research in this area a long time ago, you must know that their scientific research capabilities are much better than our small laboratory. ”

Professor Liu, who usually doesn't talk much, also said two more sentences this time, which should also have something to do with Wang Zhengguo's initiative to ask questions about materials before, if Wang Zhengguo is a robot who only listens to commands, does things according to fixed procedures, and does not put forward his own ideas, generally speaking, Professor Liu is too lazy to explain so much.

The assistant can have his own ideas and indeed have the right impact on the project, which shows that this person has ten potential, and Professor Liu is also happy to say a few words, which can be regarded as a pointer or two.

Just said a few more words, and indeed saved the whole project, after all, it is a standard military fan, speaking of military translucent resin materials, he also immediately thought of one thing: fighter cockpit canopy.

That's right, Wang Zhengguo remembered the cockpit cover of the fighter jet, in fact, this thing is made of resin materials, and it can only be made of resin materials, in contrast, if the cockpit canopy is made of inorganic silicate glass materials, then the problem is really big.

Inorganic silicate glass is a typical brittle material, usually the window glass used at home is typical, is a kind of fragile object, think about the aircraft in high-speed flight, if the cockpit canopy is broken, the broken glass will directly set up a sharp blade to kill the pilot; the processing performance of silicate glass is not very good, it is difficult to make a complex curved surface shape; at the same time, its material density is much greater than that of resin material, which is not conducive to the weight reduction requirements of the aircraft.

As early as World War II, researchers found that plexiglass made of resin materials has excellent toughness and light transmittance, and then it was first used in the windshield of aircraft and the vision mirror of the cockpit of the tank driver.

Therefore, the resin translucent material is actually produced in response to the needs of the military, and it only began to transition to gradual civilian use after the war, so it also proves once again from the side that military scientific research technology is indeed ahead of the development of civilian technology in many cases.

Thinking about it, I feel hopeful: "Professor, I suddenly remembered a question, military resin materials, this time it's really hard to say whether there is one, you know that my parents are in the military industry, so I know more about this aspect, the actual military aircraft use the light transmission material is made of resin, and because of military standards, the light transmittance is definitely not low." ”

Wang Zhengguo himself overturned the material problem he just said, and then remembered that there is such a stubble, if the fighter cockpit canopy material is used to make optical lenses, maybe it really works, that thing is light in weight, the light transmittance is also very good, and the price is not high, so it can show its skills in the civilian field.

I was already bound by various problems, and the professor planned to do it again, but I didn't expect this assistant to make a 180-degree turn, from just questioning the problem of domestic materials, to proposing that there are materials in China that can meet the needs of use, and I asked what is this?

But the good news is good news after all, whether it is all the way to the top or the peak, it is worth being happy and worth caring about: "It's a bit possible for you to say this, but I'm not very familiar with this piece, are you sure that the military industry has relevant materials to meet our requirements?"

Looking at this situation, it is obvious that the professor feels that what his assistant said is a little unreliable, and people are still suspicious of Wang Zhengguo, which is definitely not good, and he must prove his strength and prove the professionalism of a military fan in military knowledge.

Sitting opposite the professor, he straightened his waist and gave a very clear affirmative answer: "Professor, don't believe it, what I said this time is absolutely reliable, completely opposite to the situation I just proposed, and the fact now is that we can do this project, and the relevant material technology has been used very maturely in China, mainly in the field of military industry!"

Wang Zhengguo sat precariously, and his serious answer was effective, and there was still some doubt in Professor Fangcai's eyes, but now it has finally changed, from the previous listlessness and indifference, to the instant chicken blood, and asked:

"In that case, do you have an exact source of information, do you know where this material is produced?"

Knowing that the professor's Red Cross Society was the result after hearing the news, Wang Zhengguo also continued: "I am very sure of this, my father is an employee in the aviation industry, if we are interested, I think we should be able to go directly to the 123 factory in our city to investigate, they must have aviation-grade translucent parts production there." ”

Professor Liu is relatively clear about the military units around Shudu, and he also knows a little about Wang Zhengguo's family background, and he also understands that among the military units around Shudu, only Factory 123 may have this kind of thing in production.

Since it is very likely that there is such technology in China now, it seems that I am really right, although there is no application of this technology in the civilian field, but the military field can always give people unexpected surprises.

Thinking quickly and sorting out the clues, the professor stood up and made a direct decision: "Since you are sure that there will be this kind of translucent parts production in Factory 123, then we don't want to sit here and wait, I will go to the school immediately to open a letter of introduction, and I will go directly to Factory 123 tomorrow to see, this news is too timely, we must confirm it on the spot, and wait for me in the laboratory at eight o'clock tomorrow morning." ”
