Tech house system

With the precedent of Jin Weiping's success, some students who were unwilling to do so also tried their best to show it.So when I visited the simulation experiment in the afternoon, it became like a battlefield.

The control center will give some explanations of aviation technology to the students, which are relatively simple and just enough for the students to understand. The laboratory is also a simulation laboratory specially open to visit, and the technology is relatively simple.Originally, it was a laboratory that simply wanted to arouse students' interest and confidence in aviation science, but because of Jin Weiping's performance in the morning, it became the fuse.

"Teacher, I have a question!" Just after the researcher here introduced a technology, some students raised their hands: "You said that this pneumatic actuator is single-acting, but in 2015 there was a paper "Pneumatically Executed Gas-Liquid Cracking Method" 》I mentioned the double-acting type, and there are data showing that the double-acting type is more stable than the single-acting type, what do you think?"

This is the 10th student who raised his hand to ask a question. Unfortunately, his name is still not Wei Shuxun.

Wei Shuxun never got a chance to raise his hand.

He originally wanted to pretend to be a brash and eager student, and asked all kinds of nonsense questions during the visit. Of course, he was ready to be hated. Anyway, he just wanted to find an opportunity to relate the problem to "aeroelasticity." Domain” related technical issues, and then pretend to have a big brain hole, and propose solutions.

As for whether it can reach the ears of Professor Guan Cheng, whether he will pay attention to it, Wei Shuxun is too lazy to care.Anyway, he didn't intend to get anything from Professor Guan Cheng, it was just a favor.

In the professional field of aerospace, Wei Shuxun was inferior to everyone present.He wanted to find an entry point that he could understand, and finally heard that he understood a technology. He was about to raise his hand, and several students had already raised their hands—well, if he could understand it, the others would. It is not surprising to understand.

And in terms of technology that he doesn't understand, even if he wants to mess around, he must at least come up with a reasonable question first.However, before he had considered the question, the other students had already raised their hands and finished speaking.

Therefore, the visit in the afternoon has been going on for more than two hours, and Wei Shuxun has not been able to find a chance to mess around!

The saying that knowledge is power makes sense sometimes.

Without knowledge, you don't even have the qualifications to raise your hand to ask questions!

Later, Wei Shuxun simply called out the learning machine to help. When the researcher gave a speech on the stage, various related technical materials were displayed on the empty screen of the learning machine. It felt the same as in class. Even understood the principle of seven or eight points.

Wei Shuxun felt that he had a good understanding of technology, and he was confident in asking questions. When he looked up, he saw the researcher's dry lips.

This is the 10th student who asked a question. After visiting for more than two hours, deducting the time for explanation, it means that one student asked a question in less than 10 minutes.

It's not that the students are ignorant, it's just that they are young and energetic, and they can ask more insightful questions. Seeing others get praise for this, they can't help showing weakness, which caused this situation for a while.

This researcher is Xiao Zheng from the morning. He probably knew what the students were thinking, and he already had a helpless look on his face, but he still took the microphone and answered seriously: "This student is very good, and he has a wide range of reading. What did you say?" The paper "Pneumatically Implemented Gas-Liquid Cracking Method" was published by Professor Huang of our center, and I didn't expect that there were students paying attention to it!"

His words made the student look happy, and Wei Shuxun saw a professor next to him stomping his feet, probably the teacher who led the student.

The professors asked the students to perform because they wanted to give the students a chance, but the professors had no way of saying what to do. After all, it was impossible to rehearse in advance, and it only depends on the flexibility of the students themselves.

For example, Jin Weiping's question this morning showed his knowledge without causing trouble to others, and won the favor of the researcher.

However, the students' ideas are relatively simple and straightforward. If you know it, I will do it too. Why are you the only one to be praised.So, that's it, everyone came to ask questions. Of the 165 students, there are only 10 asking questions so far, which is not many, but the frequency of asking questions is too urgent, and the utilitarian heart is clearly revealed.

The professors wanted to stop them, but there were so many students, and they didn't know which one would ask questions, so they could only stamp their feet on the sidelines.

Seeing that Researcher Xiao Zheng's mouth was dry, Wei Shuxun couldn't bear to ask any more questions. Even if he wanted to make trouble, he should at least change the time or someone else, otherwise he always felt that he couldn't do anything to embarrass the serious Researcher Zheng.

"I hate it, how long are these people going to ask questions?" A girl next to Wei Shuxun complained dissatisfied.

"That's right, didn't you see that the teacher's mouth was dry?"

There were also many reasonable students, and there were complaints from time to time, but this did not stop some students from expressing their eagerness. As soon as Researcher Xiao Zheng finished answering, four or five students immediately raised their hands.

"Mr. Zheng, I have a question." An eager student asked without waiting for Xiao Zheng's nod, "You just explained that the single-acting type is used to reduce the pressure on the operating valve, but as far as I know, the pressure on the operating valve Too small will lead to insufficient lateral energy, how do you solve this problem?"

"I said, that's enough!" Seeing Researcher Xiao Zheng licking his dry lips and preparing to answer again, Wei Shuxun became impatient.

He is now a good student on the surface, but he is still a gangster in essence. Seeing that some guys completely ignore the troubles they bring to others and ask questions endlessly, Wei Shuxun pushed everyone away and walked to the front of the stage, glaring at the man who raised his hand. The person who asked the question: "Didn't you see that Mr. Zheng is tired, and we haven't finished the tour yet, please some people don't waste everyone's time!"

His words won the nods of most people, but angered some people. The student who asked the question said dissatisfiedly: "I am not trying to embarrass the teacher, I just have a question, you are, what do you mean by making trouble on purpose?" ?”

"That's right, it's as if our questioning is deliberately asking for trouble!"

"You just want to take the opportunity to express yourself!"

It seemed that some people regarded him as the same kind, and when they saw him stand up and perform, they became even more noisy.

Wei Shuxun's face darkened, although he had planned to do so, but he would not just focus on expressing himself when others were tired - this is clearly a reaction, he is not so stupid.

"He's right, it's just that you keep asking, which delays our visit." Someone among the students said.

"That's right, why don't you go back to school if you love learning so much, what are you pretending here!"

Not everyone wants to rely on this trick, and there are many people who have opinions, but no one dared to say it before. Wei Shuxun took the lead, and the dissatisfied people also criticized politely.

"We are here to learn, what's wrong with asking questions!"

"You have influenced others, don't you understand?"

So the students started to quarrel because of disagreement.Although not everyone is arguing, a dozen people arguing can also appear chaotic in a closed laboratory.Several professors wanted to go up to stop them, but the quarreling students were crowded in the crowd. They followed the voice to find the person, but they still couldn't find anyone. As for the verbal orders, the quarreling students didn't listen at all.

"Students, be quiet, be quiet..." Researcher Xiao Zheng was a little anxious, and called out to be quiet with the microphone, which made the scene even more chaotic, because everyone was raising the volume.

Wei Shuxun put his hands in his trouser pockets, his face full of impatience.If he was still a gangster, he would have punched and thrown out earlier, and there would be no quarrel, wasting time.But researcher Xiao Zheng seemed to be very embarrassed, Wei Shuxun directly grabbed the microphone in his hand, pointed at the student who asked the question just now: "Enough, I love asking questions so much, I will answer you!"

"The solution to the lack of lateral energy due to too low pressure of the operating valve is to add a ball core to the two operating valves. The rotation of the ball core will intercept the fluid, and the pressure difference between the upstream and downstream will make the liquefied energy close to the downstream. Seat..."

Halfway through Wei Shuxun's speech, the audience had quieted down, and everyone looked at Wei Shuxun blankly.

"When the pressure is reached, the butterfly valve starts. The butterfly plate rotates around the valve stem with a 35vr power source, forming parallel with the flow direction of the liquefied energy. At the same time, the force of the pressure difference on the butterfly plate will increase by 5-15%. The value of this activity will be It adjusts and balances with the movement of the actuators, so there is absolutely no lateral energy deficit.”

Wei Shuxun finished speaking in one breath, pointing to the few students who were still making noise just now: "Okay, if anyone else wants to ask questions, ask them until you are satisfied."

"Who... do you think you are... can you answer it?" Even though he said this, the student's momentum was obviously much weaker, and his voice was a little lower than normal.

"Then just ask!" Wei Shuxun punched behind him, making a loud bang, and some guilty students almost jumped up in fright: "I'm here today to play quizzes with you, if there is a question If I can't answer, I'll pack up and leave immediately! Who will come!"

Wei Shuxun said so, the students who were clamoring to ask questions just now didn't dare to open their mouths. Instead, they shrank their necks and hid behind the crowd. The whole laboratory was almost to the point where needles could be heard.

"This classmate, thank you." Researcher Xiao Zheng signaled Wei Shuxun to give him the microphone, and smiled at the students in the audience: "Okay, okay, whether it is a student who asks a question or a student who wants to continue to visit, I know everyone It’s all just longing for the knowledge of aerospace. Students come from different schools and different regions. It’s rare to get together. Don’t quarrel over such trivial matters! The next visit is the internal model of the space capsule, which is pressed against the real space capsule. It’s 100:1 shrunk, everyone can go in and experience it!”

With the steps he gave, the students obediently followed the instructions and walked into the side room. Wei Shuxun saw the professors catching up and ordered the students from their respective schools to gather in front of him, obviously intending to give a severe lecture.

Wei Shuxun didn't want to be reprimanded. Seeing Professor Li chasing the students in front into the side room, he immediately stood still, planning to wait for Professor Li to finish his reprimand before going in.

Someone patted on the shoulder suddenly, Wei Shuxun turned his head, and saw Researcher Xiao Zheng smiling at him and said: "Thank you just now, I can't speak harshly to the students, I almost don't know what to do."

"You're welcome." Wei Shuxun said: "Those guys are too much, Mr. Zheng, you don't have to answer them at all."

Selectively forget the fact that I almost became one of them.

"You don't need to be called Teacher Zheng, I'm not much older than you, just call me Zheng Le." Zheng Le pushed his glasses and said helplessly: "Actually, I just entered the spaceflight control center this year. My first solo job, if I can't even do this little thing well... so thank you for helping me."

"I see."

No wonder he always tried his best to answer students' questions. If he was an experienced commentator, he would have changed the topic and got confused by now!

But Wei Shuxun doesn't dislike him being serious about it.

"By the way, there is also your answer just now, it's perfect!" Zheng Le suddenly remembered Wei Shuxun's answer just now, and praised: "Isn't the answer just now a published paper, is it the answer obtained by your own experiment? Which school are you from, how old are you?"

"..." That was the answer of the learning machine.And I'm just a sophomore, and I'm just preparing to take the second degree in engineering mechanics this semester, and I'm not sure if I can pass it.

Of course Wei Shuxun couldn't answer that way, and said vaguely, "I'm a student of University A."

"University A, no wonder!" After hearing that he was a student of University A, Zheng Le stopped asking, probably taking Gao Zhi, a student of University A, for granted.Wei Shuxun wanted to go in after Professor Li finished his lecture, but Zheng Le pulled him, so he had no choice but to follow in.But with Zheng Le around, Professor Li couldn't teach him a lesson, and he didn't do anything to embarrass University A just now. Instead, he gave University A a face. Professor Li looked at him much more gently than before.

Because they were taught a lesson by the professor, there were no problems in the following visits. All the students visited honestly and took notes. The visit ended at 6 pm, and everyone went back to the dormitory to rest after eating.

The space flight control center is a military restricted area, and students are not allowed to walk around outside of visiting hours, so the students must go back to the dormitory to rest honestly after eating.

Wei Shuxun put down the bowl and chopsticks and was about to go back to the dormitory with Han Zhixin, when he suddenly heard a beeping sound in his head: "The task is released, please help Zheng Le repair the machine that was destroyed by you."

The author has something to say: I don't know if you have such an experience.

During group visits or meetings, there are always one or two people who love to ask questions, and even ask their own questions even if everyone is waiting.

The most important thing is that this kind of person doesn't really want to know the answer, but just to show that he "loves learning or knows a lot".

Personally, I hate this guy so much.
