Chapter 316

EQ, what is the level?

It is normal EQ to observe, then think, and finally say words that conform to the situation and the other party's three views.

On this basis, it is high to add creative, provocative and humorous elements to make each other comfortable and seduce the other's expectations.

On this basis, we do not observe, think, how to spray, or keep silent, only know not, is low.

Li Zheng's EQ, which is left back horizontal jump, fluctuates repeatedly, nine deep and shallow, which is only related to the object he communicates with and the situation he is in.

For example, most people, in front of their family or close friends, will not play observation and think about this set of flattering each other, what to say.

In this situation, everyone has low EQ and exposes himself without cover up.

Especially for men, if good friends cut their heads, they will probably scold and be forced. If good friends play games to pull their hips, they will scold the vegetable forcing. If they lose love, they will go to bed and trampoline.

Women are more delicate, no matter how ugly a girl bought a skirt, they should be surprised to boast "really beautiful ~ ~ ~".

Li Zheng, however, is only a large range of "own people".

The world studies the people in Xinjiang, anyway, it is my magic field in the morning and the evening.

In contrast, Lin Yue Jing's "own people" is too small, because she has experienced too many tragedies that are not intended to hurt people because of her intelligence. She chooses to use "um" instead of language expression.

Over time, it is equivalent to abandoning Eq. at the same time, it also loses some language ability.

Therefore, suddenly entering the workplace, Lin yuejing had to rely on others, or he would be punished.

Without her mother's shelter, she can only stare at Li Zheng all the time, and then she can wait for the opportunity to copy his skills.

Li Zheng, although the scope of "his own people" is very large, it is not usually the first time to give up the weapon of EQ, especially to communicate with the predecessors, the posture should be put forward.

So he began to observe.

[zhumingyue]

br > learning ability: 1959]

stable, the level of experts in the field, their own people.

And then, combining with his present state, he actively reveals his private affairs

Li Zheng has already known what he needs most.

"I think you are just like a rebirth, and this mental state is more energetic than many students." Li Zhengzhen nodded, "although we don't know the specific internal situation, but since we have taken this step, we will walk the next road frankly, and don't think about it again."

Lin Yue was completely surprised by this sentence.

This is no longer a problem of EQ or EQ, it is just a scum!

Zhu Mingyue had some regrets to say these when he first met, but Li Zheng made him feel comfortable in a moment.

"Thank you for your comfort." Zhu Mingyue chuckled his head. "I didn't expect The first person who is sure of me is the first time you meet My friends and relatives are advising me to turn back. My colleagues are very secretive. You can understand my state more It has to be said that the minds of young people are really too rich now. "

He said, looked back and forth at the two people, then asked with a stare.

"You are Is middle school together? It's true that I'm with my ex-wife. "

Facing this problem, Li Zheng's EQ thought seems to be suddenly blocked by a cycle of death.

And then it was short circuited

Lin Passover Jing has a kind of impulse to come out of the door.

"Ah, sorry, I shouldn't say that. I'm a little excited today. Understand it." Zhu Mingyue said to open an email and turned up the resume of the two people. "Secretary Zhao told me that you have a set of data analysis. If you don't mind, your advanced test team will know the situation and be familiar with the work by the way. I know you are most interested in engine engineering, but I suggest that you start with a simpler foundation work, otherwise there will be a great sense of fragmentation, it is difficult to really participate in the work. "

"I am honored." Li Zheng points the lead.

"OK, I'll call the person in charge." Zhu Mingyue said to pick up the seat receiver, but thought, and put it down for a while, and said instead.

"If you have any questions or ideas, you may as well say it directly."

"Secretary Zhao reminded me many times that you should not stare at the education background and get into a solid cognition, which will waste your talents."

"As the old director of the 17 Institute, the Secretary has experienced almost all the opportunities and difficulties of the space system since the 1990s, and I believe in his judgment and his vision."

Zhu Mingyue said, nodding with a little deep meaning.

"You don't have to be polite. If you have a word, you are all from your own family."

This is a very kind person.

Some sensitive things, the team leader below is not convenient to talk about, or they don't know.

Li Zheng naturally accepted the beauty and tentatively said, "then I'll be brave enough to ask seven or eight questions... """So much..." Zhu Mingyue swallows to spit, drank a big saliva to just raise a hand way, "although asks."

"First of all, what's the situation of yf-87's team and how can it allocate resources?"

"Zhu Mingyue, the first person in charge of the hospital, was not the first one who was in charge of it

"Because our staff and kerosene engines are relatively independent, the main backbone has not been affected. Although I have passed the annual leave and sick leave here, most of our comrades have returned to their posts yesterday."

"When we had a meeting yesterday, we had unified up and down and made it clear that we would try again."

"As for resources, both inside and outside the hospital, are in the stage of adjustment."

"Every hospital has its own work plan and schedule, and there is no end of work to be done anywhere. Before that time, everyone always ranked Huang er's affairs as the first priority."

"It can be said that as long as Huang Er has a demand, no matter who he is, he should immediately put down his work and start the huanger project immediately."

"At this stage, with the proposal of 927, this preferential treatment is bound to disappear, and all institutions are bound to gradually turn to 927."

"However, if we really have breakthrough progress and core needs, Secretary Zhao will still help to speak. He is a person who dares to break into the office of the chairman of the group..."

"But only if these requirements do not conflict with the 927."

"It's impossible for 927 to slow down and wait for us."

"Well, keep asking."

Judging from Zhu Mingyue's words, he basically has no concealment, and Zhao Zhenhua seems to have made a good account of it.

It seems that in the expectation of the old secretary, he is not so simple as to come to practice.

Li Zheng is no longer rigid, immediately asked: "at this stage, the possible cause of the failure has an explanation?"

"Well What did you know before 87? " Zhu Mingyue asked.

"Only know that the problem is the oxygen turbine pump."

"That's a good explanation."

Zhu Mingyue said with a stroke.

"As you all know, in order to fully burn the fuel and increase the specific impulse, the pressure in the combustion chamber will be very high."

"That means a turbine strong enough to inject more fuel into the combustion chamber against this pressure."

"It's like having a bottle of coke after crazy shaking, and you have to fill it with more cola. We do this with a turbine."

"If you want to inject fuel into a combustion chamber at 100 atmospheres, you can imagine the power of the turbine, so where is the energy that drives the turbine to do its work?"

Speaking of this, Zhu Mingyue looked at the two of them for a long time before he was helpless: "don't look at me I'm asking questions Of course, Secretary Zhao's eyes are fine, but I have to know the truth. "

After that, he looked forward slightly and said to them, "time is limited. I can't give you a set of papers. We can communicate at any time and investigate at any time. I will arrange the study and work in the future according to your level. If you can answer, you can answer as much as you can, and if you can't answer, you can guess."

Hearing the speech, Li Zheng immediately started thinking.

But as soon as he began to think about it, Lin said, "another combustion chamber is designed inside the engine to burn hydrogen and oxygen fuel in advance to push the turbine?"

"Yes." Zhu Mingyue said with a smile, "it seems that chief engineer Shen told you about it."

"Well..." Lin Yu Jing's head lowered and he said "no" very quietly.

Zhu Mingyue didn't notice and went on talking.

"This chamber is called a precombustion chamber, where hydrogen and oxygen fuel burn ahead of time to push the turbine."

"Speaking of this, I have to ask questions again. Don't be bothered by me. I just understand the basis of your various disciplines."

"What is the full combustion temperature of hydrazine propellant like liquid hydrogen and oxygen?"

This is looking at Lin Yue Jing asked, just the question obviously ignited Zhu Mingyue's expectation for her.

However, Lin Yue Jing just grabs his pants and bows his head, like a pupil who is suddenly asked by the teacher when he is distracted.

This time, Li Zheng next to him was very confident: "it should be more than 3000 degrees."

Zhu Mingyue's attention turned to Li Zheng: "what kind of material can withstand such a temperature?"

Li Zheng thought for a moment this time and even shook his head.

"I don't know..."

"The maximum service temperature of stainless steel is about 1000 degrees. High temperature alloys used in aerospace engines usually can't exceed 1500 degrees. Cermet will be higher. But I'm not sure its inherent properties are suitable for blade materials..."

"If we just look at the melting point, hafnium alloy, graphite, diamond, tungsten and other materials can indeed exceed 3000 degrees, but they are too expensive and rare, or they are not competent for the special tasks of engines due to their plasticity and brittleness..."

"So, I can't think of a material that can be used in space engines on a large scale and can withstand the high temperature of 3000 degrees..."Zhu Mingyue heard the last, unconsciously began to Baji mouth.

"Chemistry and materials science are good, too."

"Ah..." Li Zheng waved his hand modestly, "it's just that I participated in a few small competitions I can't even think of such a material... "

"It's right not to think of it. I can't think of it." Zhu Mingyue said with a smile, "this kind of perfect material only exists in theory. The materials from all over the world may not be able to make a rocket. Most of the alloys we use on a large scale have working temperatures within 1500 degrees, which is mainly achieved by special coating and propellant flow."

"However, in the turbine pump blades, these technologies are greatly limited."

"In short, this part cannot be cooled at this stage, and the upper temperature limit of the precombustion chamber is only 1300 degrees."

"But the temperature of full combustion of liquid hydrogen and liquid oxygen is 3000 degrees."

"What to do?"

Lin Qijing, who has been silent for a long time, suddenly got excited: "not enough combustion Excessive combustion? "

"It's true that by injecting excess hydrogen, or oxygen, into the precombustion chamber, we're creating inadequate combustion, keeping the internal temperature within 1300 degrees." Zhu Mingyue turned his head again and was attracted to Lin's side. "So the question comes again, is it hydrogen excess or oxygen excess?"

"It must be hydrogen." Lin Qijing nodded vigorously, "high temperature pure oxygen will lead to severe oxidation and corrosion, who can withstand it?"

"Very, very good." Zhu Mingyue wanted to clap his hands. "If it wasn't for Mr. Shen's guidance, it was all up to you. I really haven't seen your brain..."

Before he finished speaking, he quickly said to Li Zheng, "that You're smart, too. There's no other meaning... "

"It's OK. Go on..." Li Zheng's face is extremely plain, "used to."

So is Lin Qijing, and so is guijianfeng

Facing this kind of brain circuit which is not human, Li Zheng has been used to it for a long time

"Well, go on." Zhu Mingyue coughed his throat and said, "such excessive hydrogen combustion will inevitably produce waste gas, so we need to set up an exhaust system..."

"In the first zero fault model, it was the exhaust system that went wrong."

"Simply put, the exhaust port is broken, resulting in air flow blockage."

"In a short period of time, the air flow that propels the turbopump suddenly decreases sharply, and then the fuel cannot be injected into the combustion chamber."

"The combustion stops quickly and the engine stops."

"That's the complete recurrence of the fault."

"Such a failure has never occurred in the previous test run of more than 30000 seconds."

"We believe that it was Huang er who encountered a special resonance in the extreme environment during his ascent, which led to the failure of the exhaust system."

"This exhaust design is time tested and there has never been a precedent before."

"At that time, we thought it was bad luck and the boat capsized in the gutter."

"After identifying the fault point, we raced against the clock to strengthen the entire exhaust system to withstand more severe conditions than in the recurrence of the fault, and then confidently delivered the new version of the engine to the test site."

"In the first two routine tests, the engine still performed well."

"You've seen the results of the third extreme environment test run."

"There is nothing wrong with the strengthened exhaust system. Instead, the shafting is broken."

"The shaft system is the core of the core. The fracture here is 10 times more serious and 10 times more complex than the exhaust fault. I'm afraid it can't be solved by repairing. Many people think that the process of finding and repairing faults is longer and harder than even redesigning an engine. "

"To make an inappropriate analogy, we first found a small leak in the dam and then filled it with cement to plug it."

"The next day, the whole dam collapsed."

"It turns out that what we're blocking is not a leak, but an ant nest."

"The Bank of thousands of miles has already been densely penetrated by ant nests."

"This is the seriousness of the problem at this stage."

At the end, Zhu Mingyue nodded.

"Therefore, I personally do not object to the 927 project."

"When chief engineer Zhang and academician Zhang fall down, I have the responsibility to take over the baton."

"But in my experience, such serious defects are very difficult to solve in a short period of time. In order not to affect the follow-up space strategy of the country, 927 is also a painful choice for big leaders, a choice that has no choice."

"But it doesn't affect our determination to do our best."

"Know that you can't do it and do it."

"Know it's hard to do it, and try to do it."

"Since its establishment, the 17 research institutes have been carrying heavy loads."

Zhu Mingyue got up and raised his right arm.

"Li Zheng, Lin yuejing."

"Welcome to China Aerospace Power Research Institute."Li Zheng clasped his hands with Zhu Mingyue and shook them vigorously: "for it! Try to do it

When Lin qiojing shook hands, he was calm and asked thoughtfully, "I don't understand one point..."

Zhu Mingyue nodded with interest: "please say so."

"Why do we have to exhaust?" Lin Qijing frowned and kneaded his chin. "There is still a lot of excessive hydrogen in the so-called exhaust gas of the pre combustion chamber. Why waste it? Is it not good to inject it into the combustion chamber? So the overall fuel efficiency of the rocket is not higher? "

Zhu Mingyue a listen to stare: "your mother really did not tell you?"

"No..."

"Then you can take over her in a few years..." Zhu Mingyue repeatedly nodded his head and explained, "of course, the design you mentioned exists, and it is the optimal design. Our yf-100 kerosene engine adopts this design, which can not only fully burn, but also double the pressure in the combustion chamber. However, as for the hydrogen oxygen engine, it has higher requirements on structure, parts, pumps and materials, so we can not challenge the highest difficulty at the first step. Therefore, we adopt the gas generator cycle which needs exhaust. "

"Well..." Lin Yujing breathed a sigh of relief, "it's smooth..."

"I don't understand Secretary Zhao's boasting about you Now I accept it completely. " Zhu Mingyue pursed his mouth and nodded, "18 years old, my God The education system has been working for so many years, which can be regarded as the cultivation of people like you. "

As soon as Zhu Mingyue finished, he quickly turned to Li Zheng and said, "of course, there are still others like you It's you. I was wrong... "

"It's OK. I'm used to it. I'm used to it..."

"Well, in view of your level, the test team should not go." Zhu Mingyue then arranged, "a temporary fault investigation team will be set up immediately. There is a person who is absolutely enough to be your teacher to act as the team leader. You can directly follow him."

Just as he was saying that, behind him came a unique and intensive knock on the door.

Dong Dong, Dong Dong Dong, Dong Dong Dong, Dong Dong Dong

For this knock, Li Zheng still has some impression that it is a prime number sequence.

However, his face was stiff, and he had a bad premonition.

"In." Zhu Mingyue road.

Immediately, an old handsome face poked in: "wait for a long time, insert a team?"

Zhu Mingyue was overjoyed and rushed to meet the people himself. He took the hand of the commander-in-chief Du Songtao: "this is chief engineer Du Songtao. NASA is eager for the top experts. He is impatient to ask for the rocket and so on. He specially asks for the support of our 17 research institutes. From now on, you will follow him."

"Ah..."

"Well..."

Li Zheng and Lin yuejing were happy.

All of a sudden it's not good.

There's a sense of spore man spies breaking into human beings, parasite or something.

Du Songtao, however, was quite happy. When he entered the room, he made a glass of water by himself. He walked up to them, drank the water and picked his eyebrows: "this is not a coincidence."

Coincidentally your mother, this is obviously the plot of spore man!

Looking at their strong hostility, Zhu Mingyue asked: "know?"

"Not familiar."

"Not familiar..."

"Better to know." Zhu Mingyue said, "then you two go out and wait. I'll talk to Songtao about a few things."

They went out of the office with their heads down.

Then I ran into the big brother with long inch head in front of them.

The elder brother stood at the same place in confusion: "an hour I worked hard in line And to you Why did you jump in the queue Can't you talk to me about it... "
