Tech House System

There is a precedent for Jin Weiping's success, and some unwilling students also work hard to show. So when I visited the simulated experiment in the afternoon, it became a battlefield-like existence.

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

"Teacher, I have a problem!" As soon as the researcher here introduced a technology, a student raised his hand: "You said that this pneumatic actuator is a single-acting type, but in 2015 there was The paper "Pneumatic Execution of Gas-Liquid Cracking Method" mentioned the double-acting type, and there is 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 bold and eager student, and asked all kinds of rambunctious questions during the visit. Of course, he was already prepared to be hated. Anyway, he just wanted to find an opportunity to The problem is related to the technical problems related to "aeroelasticity to the domain", and then pretend to be open-minded and propose solutions.

As for whether it can reach Professor Guan Cheng's ears, 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, just as a help.

In the professional field of aerospace, Wei Shuxun is no better than everyone present. He wanted to find an entry point that he could understand. He finally heard a technology that he understood. He was about to raise his hand, and several classmates had already raised their hands - well, if he can understand, others will understand. Not surprising.

In terms of technology he doesn't understand, even if he wants to mess around, at least he has to come up with a reasonable question first. However, before he could think about the question, the other students had already raised their hands and finished speaking.

So, the afternoon visit 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 sometimes makes sense.

Without knowledge, I don’t even have the qualifications to raise my hand to ask questions!

Later Wei Shuxun called out the learning machine to help. When the researcher gave a speech on the stage, the empty screen of the learning machine displayed various related technology information. It felt the same as in class. While listening to the actual speech, I even understood the principle of seven or eight points in a hurry.

Wei Shuxun knew about the conscious technique and asked questions with confidence. As soon as he looked up, he saw the researcher's dry lips.

.

This researcher is Xiao Zheng from the morning. He probably knew what the students were thinking, and he had a helpless look on his face, but he still took the microphone and answered seriously: "This classmate is very good, read The scope is very wide, the paper "Pneumatic Execution of Gas-Liquid Cracking Method" you mentioned was published by Professor Huang of our center, and I didn't expect that students would also pay attention!"

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

Professors call students performance, and they want to give students a chance, but they can't say how to do it.

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

The ideas of the students are relatively simple and straightforward, you know what I will, why only you get praise. So, that's it, everyone came to ask questions. Of the 165 students, only 10 have asked questions at present, which is not much, but the frequency of questioning is too urgent, and the utilitarian heart is obvious.

Professors tried to stop it, but there were so many students who didn’t know which one would ask questions, so they could only stomp on the side.

Seeing Researcher Xiao Zheng talking about his dry mouth, Wei Shuxun couldn't bear to ask any more questions. Always feel unstoppable.

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

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

hand.

"Mr. Zheng, I have a problem." An eager student asked directly without waiting for Researcher Xiao Zheng to nod: "You just explained that the single-acting type is used to reduce the pressure of the operating valve, but As far as I know, if the operating valve pressure is too low, the side energy will be insufficient, how did 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 a good student on the surface, but he is basically a gangster. Seeing that some guys completely ignore the troubles they cause to others, and want to ask endless questions, Wei Shuxun lined up to leave Before arriving at the stage, he glared at the person who raised his hand to ask questions: "Didn't you see that Mr. Zheng is tired, and we haven't finished the tour yet, please don't delay everyone's time, please!"

His words were greeted with nods by most people, but angered some people. The student who asked the question said dissatisfiedly: "I don't mean to embarrass the teacher, I just have questions, you Yes, what does it mean to come out to make trouble on purpose?"

"Yeah, it's like we're asking for trouble on purpose!"

"You just want to express yourself!"

It seems that some people regard him as the same kind, and seeing him stand up and perform, it makes him even more noisy.

Wei Shuxun sank his face, although he used to have this plan, but he would not look at others tired and only focus on expressing himself - this is obviously counterproductive, he is not so stupid.

"He's right, it's just that you've been asking, delaying our visit." Some of the students said.

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

Not everyone wants to rely on this trick, and there are many people who have opinions, but no one dared to say that Wei Shuxun took the lead, and those who were dissatisfied were not polite to criticize.

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

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

The students began to quarrel because of disagreements. Although not everyone was arguing, it was chaotic even in the closed lab with a dozen people arguing. Several professors tried to stop it, but the quarrelling students were crowded into the crowd. They followed the voice to find no one. As for the verbal orders, the quarrelling students didn't listen at all.

"Classmates, be quiet, be quiet..." Researcher Xiao Zheng was a little anxious and shouted for quiet with a 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 throw one punch at a time, and what would he quarrel with would be a waste of time. But it seemed very difficult to see Researcher Xiao Zheng. Wei Shuxun grabbed the microphone in his hand and pointed at the student who just asked the question: "Enough, I like to ask questions, I will answer you!"

"The solution to the insufficient side energy due to the 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 generated between the upstream and downstream, will place the liquefied energy against the downstream valve seat…”

Halfway through Wei Shuxun's speech, the audience was quiet, and everyone stared at Wei Shuxun.

"When the pressure is reached, the butterfly valve starts. The butterfly plate rotates around the valve stem with a 35vr force source, which is parallel to 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%, this activity value will be adjusted and balanced according to the movement of the actuator, so there will be absolutely no problem of lack of lateral energy.”

Wei Shuxun finished speaking in one breath, pointing to the students who were still making a fuss: "Okay, who else wants to ask questions, ask until you are satisfied."

"Who...do you think you are...can you answer it?" Despite this, the student's aura 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 with you today. I'm playing the quiz, if there's a question I can't answer, I'll leave immediately! Who's coming!"

Wei Shuxun said this, the students who were still clamoring to ask questions didn't dare to speak at all. Instead, they shrank their necks and hid behind the crowd. The entire laboratory was almost at the point where needles could be heard.

"Thank you, classmate." Researcher Xiao Zheng motioned Wei Shuxun to give him the microphone, and smiled at the students in the audience: "Okay, okay, whether it's the classmate who asked the question, or the student who wants to For the students who continue to visit, I know that everyone just yearns for the knowledge of aerospace. The students come from different schools and different regions, and it is rare for them to get together. Don’t quarrel over such trivial matters! And the real space capsule is reduced by 100:1, everyone can go in and experience it!"

With the steps he gave, the students obediently followed the instructions and walked into the room to the side. Wei Shuxun saw the professors chasing after him and ordered the students of their respective schools to gather in front of him, obviously It was planned to give a severe lecture.

Wei Shuxun didn't want to be taught a lesson. 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 entering.

Suddenly someone tapped on the shoulder, Wei Shuxun turned his head, and saw Researcher Xiao Zheng smiling and saying to him: "Thank you so much just now, I can't speak hard to students, almost know what to do."

"You're welcome." Wei Shuxun said: "It's those guys who are going too far. Teacher Zheng, you can absolutely not answer them."

Selectively forget the fact that you almost became one.

"You don't need to call Mr. 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 space flight control center this year. Hosting you to visit and explain this time is my first independent job, if I can't do this little thing well... So thank you for helping me."

"So it is."

No wonder he always tries his best to answer students' questions. If he was an experienced narrator, he would have changed the subject long ago!

But Wei Shuxun doesn't hate him for being serious.

"By the way, and your answer just now, it's perfect!" Zheng Le suddenly remembered Wei Shuxun's answer just now, and praised: "The answer just now is not a published paper, it's you Did you get the answer from your own experiment, which school are you from, what kind of student are you in?"

"..." That is the answer of the learning machine. And I am only a sophomore. I am just preparing to take the second degree in engineering mechanics this semester, and I am not sure if I can pass the exam.

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

"A university, no wonder!" As soon as he heard that he was a student of A university, Zheng Le stopped asking questions, probably thinking that Gao Zhi, a student of A university, was taken for granted. Wei Shuxun wanted to go in after Professor Li's lecture was over, but Zheng Le pulled him, so he had to follow up. However, with Zheng Le around, Professor Li couldn't teach him a lesson, and he didn't do anything to shame A, but instead made A's face, Professor Li looked at him with a much gentler look than before.

Because they were taught by the professor, there was no problem in the next visit. All the students visited honestly, took notes, and ended at 6 pm. After the visit, everyone had a meal Back to the dormitory to rest.

The space flight control center is a restricted military area. Students are not allowed to walk around outside the visiting hours. Therefore, students must return to the dormitory to rest after eating.

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

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

When there is a group visit or a meeting, there are always one or two people who love to ask questions. Even if everyone is waiting, they have to ask their own questions.

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

Personally, I really hate this kind of person.
