Emotional intelligence, what is high and low?

Observing first, then thinking, and finally saying words that are in line with the situation and the other person's three views is normal emotional intelligence.

On this basis, it is high to be able to appropriately increase creative, provocative, humorous and other elements to make the other party comfortable and seduce the other party's expectations.

Under this basis, don't observe, don't think, how cool and how to spray, or keep silent, only know that it is low.

And Li Zheng's emotional intelligence is a horizontal jump from the left back, fluctuating repeatedly, nine deep and one shallow, which is actually only related to the object he communicates with and the situation he is in.

For example, most people, in front of family members or very close friends, most of them will not play the game of observation and thinking to please each other, and what to say.

In this situation, everyone has low emotional intelligence and unabashedly exposes themselves.

Especially for men, if a good friend cuts his head, he is likely to be scolded, if a good friend plays a game and pulls his crotch, he will be scolded, and if he falls out of love, he is afraid that he will go to bed and jump down.

Women are much more delicate, no matter how ugly a skirt their girlfriends buy, they have to praise "so good-looking~~~" with a pleasant face.

And Li Zheng is just a relatively large scope of this "own person".

The people in the world are studying in the territory, anyway, sooner or later they are all from my Demon Domain.

Relatively speaking, Lin Yujing's scope of "own people" is too small, because she has experienced too many tragedies that she has no intention of hurting others because of her superior IQ, and she chooses to use "hmm" instead of language expression.

Over time, it is equivalent to abandoning emotional intelligence, and at the same time losing part of the language ability.

Therefore, suddenly entering the workplace environment, Lin Yujing had to rely on others, otherwise she was afraid that she would suffer.

Having lost her mother's protection, she can only keep an eye on Li Zheng now, waiting for an opportunity to copy his skills.

And Li Zheng, although the scope of "his own people" is very large, he usually does not give up the weapon of emotional intelligence when he meets for the first time, especially when communicating with his predecessors, his posture still has to be posed.

So, he began to observe.

【Zhu Mingyue】

[Academic Ability: 1959]

Steady, field expert level, own people.

Combined with his current state, he took the initiative to confide in his private affairs......

Li Zheng already knew what he needed most.

"I think you're completely reborn, and your mental state is more energetic than many students. Li Zheng nodded and said, "Although we don't know the specific situation, since we have taken this step, let's take the next road calmly, don't look back." ”

This sentence completely shocked Lin Yujing.

This is no longer a question of emotional intelligence or not emotional intelligence, it's just scum!

Zhu Mingyue originally regretted saying this for the first time, but Li Zheng's words made him feel comfortable instantly.

"Thank you for your comfort. Zhu Mingyue pursed his lips and shook his head repeatedly, "I didn't expect it...... The first person to affirm me was you who met me for the first time...... My friends and relatives are trying to persuade me to turn back, and my colleagues in the unit are secretive, but you can understand my state better...... I have to say that the minds of young people are really too rich now. ”

As he spoke, he looked back and forth at the two of them, and then asked with a glare.

"You are...... We've been together since middle school? Truth be told, so did my ex-wife. ”

Faced with this problem, Li Zheng's emotional intelligence idea seems to have suddenly been stuffed into a dead loop.

And then it short-circuited......

Lin Yujing even had an urge to rush out of the door.

"Ah, I'm sorry, I shouldn't have said this, I'm a little excited today, understand. Zhu Mingyue clicked on the email as he said and flipped up the resumes of the two, "Secretary Zhao has explained to me, you are very good at data analysis, if you don't mind, your advanced test team will understand the situation and familiarize yourself with the work by the way." I know you're most interested in engine engineering, but I'd recommend starting with the simpler basics, otherwise there's a lot of disconnect and it's hard to really get involved. ”

"It's a great honor. Li Zheng nodded.

"Okay, then I'll call the person in charge. Zhu Mingyue said and picked up the landline earpiece, but after thinking about it, he put it down for the time being, and said instead.

"If you have any questions or thoughts, just say so. ”

"Secretary Zhao has reminded me many times, don't stare at your academic qualifications and fall into a fixed cognition, that will waste your talent. ”

"As the old director of the 17th Institute, the secretary has experienced almost all the opportunities and difficulties of the space system since the 90s, and I believe in his judgment and his vision. ”

Zhu Mingyue said, nodding slightly meaningfully.

"You're welcome, if you have something to say, it's all your own family. ”

This family is very kind.

There are some sensitive things, and it is indeed inconvenient for the team leaders below to talk about them, or they don't know about them.

Li Zheng naturally accepted the good intentions, and said tentatively: "That...... I'll dare to ask seven or eight questions......"

"So many ......" Zhu Mingyue swallowed and foamed, and only raised his hand after taking a big sip of water, "Just ask." ”

"First of all, how is the YF-87 team doing now, and what are the available resources?"

Zhu Mingyue was not ambiguous, and immediately replied:

"Chief Engineer Zhang's hospitalization is a huge blow, and I am temporarily the first person in charge. ”

"Because our personnel are relatively independent of the kerosene engine, the main backbone has not been affected, and although I have passed all annual and sick leave here, most of the comrades have already returned to their posts yesterday. ”

"At the meeting yesterday, we were united and made clear the attitude of fighting again. ”

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

"Each institution has its own work plan and schedule, and there is no way to finish the work anywhere, and during the previous period, everyone always put Huang Er's affairs as the first priority. ”

"It can be said that as long as Huang Er has a demand, no matter who it is, he must immediately put down the work at hand and start the Huang Er project immediately. ”

"At this stage, with the proposal of 927, this preferential treatment is bound to be gone, and the institutions are bound to begin to gradually turn around to 927. ”

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

"But only if these requirements don't conflict with 927. ”

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

"Alright, go ahead and ask. ”

Judging from Zhu Mingyue's rhetoric, he basically has nothing to hide, and Zhao Zhenhua seems to have explained it very well.

It seems that in the expectation of the old secretary, he is by no means as simple as coming to the internship to go through the motions.

Li Zheng was no longer restrained, and immediately asked: "Is there a reason for the possible failure at this stage?"

"Hmm...... What did you know about 87 before?" Zhu Mingyue asked rhetorically.

"I just know that the problem is with the oxygen turbine pump. ”

"That's easy to explain. ”

Zhu Mingyue said.

"As you all know, in order for the fuel to be fully combusted, to increase the specific impulse, the air pressure in the combustion chamber will be very high. ”

"This means that a turbine that is powerful enough to inject more fuel into the combustion chamber at this pressure. ”

"It's like having a bottle of Coke that has been shaken like crazy, and you have to keep filling it with more Coke, and we do that with a turbo. ”

"If you want to inject fuel into a combustion chamber with a pressure of 100 atmospheres, the power of this turbine can be imagined, so where does the energy to propel the turbine to do work come from?"

Speaking of this, Zhu Mingyue looked at the stunned two for a long time before he said helplessly: "Don't look at me...... I'm asking questions...... Of course, Secretary Zhao's vision is fine, but I have to find out. ”

After that, he leaned forward slightly, and said to the two of them: "Time is limited, I can't give you a set of papers, we can communicate and investigate at any time, I will arrange the later study and work according to your level, try to answer if you can, and guess if you can't." ”

When Li Zheng heard this, he immediately started thinking.

But as soon as his thinking started, Lin Yujing raised his head and said: "Design another combustion chamber inside the engine to burn hydrogen and oxygen fuel in advance to push the turbine?"

"That's right. Zhu Mingyue said with a smile, "It seems that Chief Master Shen has told you." ”

"Hmm......" Lin Yujing lowered his head and said "no" very softly.

Zhu Mingyue didn't notice it and continued to speak.

"This combustion chamber is called a pre-combustion chamber, where oxy-hydrogen fuel is burned in advance to drive the turbines. ”

"Speaking of which, I'm going to ask questions again, don't bother me, I just know the basics of your various disciplines. ”

"What is the temperature at which hydrazine propellants, like liquid hydrogen and liquid oxygen, are fully combusted?"

These words were asked by looking at Lin Yujing, and the question just now obviously ignited Zhu Mingyue's expectations for her.

However, Lin Yujing just grabbed her pants and lowered her head, like a primary school student who was suddenly asked a question by the teacher when she was 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 actually shook his head.

"I don't know ......"

"The maximum use temperature of stainless steel is about 1000 degrees, and the superalloys used in aerospace engines usually cannot exceed 1500 degrees, and cermets will be higher, but I am not sure that its inherent properties are suitable as blade materials......"

"If you look at the melting point purely, hafnium alloy, graphite, diamond, tungsten and other materials can indeed break through 3000 degrees, but they are either too expensive and rare, or they are not competent for the special tasks of the engine due to their plasticity, brittleness and other reasons......

"So, I can't think of a material that can be used in space engines on a large scale and can withstand 3,000 degrees of high temperature......"

When Zhu Mingyue heard the end, he unconsciously began to chirp.

"I have a good foundation in chemistry and materials science. ”

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

"It's right not to think of it, and I can't think of it. Zhu Mingyue said with a smile, "This perfect material only exists in theory, and the materials of the whole earth may not be able to build a rocket, and most of the alloys we use on a large scale have a working temperature of less than 1500 degrees, mainly cooled by special coatings and propellant flows." ”

"But in the case of turbine pump blades, these technologies are greatly limited. ”

"In short, this part cannot be cooled down at this stage, and the upper temperature limit of the pre-combustion chamber is only 1300 degrees. ”

"But the temperature at which liquid hydrogen and liquid oxygen are fully burned is 3,000 degrees. ”

"What should I do?"

Lin Yujing, who had been silent, suddenly became energetic: "Not fully burning...... Excessive burning?"

"Yes, we inject excess hydrogen or oxygen into the pre-combustion chamber to create inadequate combustion, and the internal temperature is controlled within 1300 degrees. Zhu Mingyue turned his head again and was sucked to Lin Yujing's side, "Then the question arises again, is it an excess of hydrogen or an excess of oxygen?"

"It must be hydrogen. Lin Yujing nodded vigorously, "High-temperature pure oxygen will lead to violent oxidation and corrosion, who can withstand this." ”

"Very, very nice. Zhu Mingyue couldn't wait to applaud, "If it weren't for Chief Shen's guidance, if you all came up with it yourself, I really haven't seen your brain......"

Before he finished speaking, he hurriedly said to Li Zheng: "That...... You're smart too, you don't mean anything else......"

"It's okay, let's continue......" Li Zheng's face was extremely flat, "Get used to it." ”

Lin Yujing is too, and so is the wind......

Faced with this kind of inherently inhuman brain circuit, Li Zheng has long been used to it......

"Okay, let's go ahead. Zhu Mingyue coughed his throat and said, "After such excessive combustion of hydrogen, exhaust gas will inevitably be generated, and we need to set up an exhaust system......

"In the first zeroing failure model, it was the exhaust system that went wrong. ”

"Simply put, it's a broken exhaust port, which causes the airflow to be blocked. ”

"For a short period of time, the air flow that propels the turbine pump suddenly and dramatically decreases, making it impossible to inject fuel into the combustion chamber. ”

"The combustion stops quickly and the engine stops. ”

"That's the complete failure reproduction. ”

"This kind of failure has never happened in the previous test run of more than 30,000 seconds. ”

"We believe that it was Huang Er's lift-off that caused the exhaust system to malfunction due to the special resonance in an accidental extreme environment. ”

"The exhaust design is tried-and-tested and has never had a precedent before. ”

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

"After identifying this point of failure, we raced against time to strengthen the entire exhaust system to withstand conditions that were even worse than in the recurrence of the failure, and then confidently delivered the new version of the engine to the proving ground. ”

"In the first two regular test runs, the engine still performed well. ”

"You have already seen the results of the third test in extreme environments. ”

"There was nothing wrong with the strengthened exhaust system, but the shaft system was broken. ”

"The shafting is the core of the core, and if there is a break here, it is ten times more serious and ten times more complex than the exhaust failure, and I am afraid it is difficult to fix it by tinkering. Many people think that the process of finding and fixing faults is even longer and more arduous than redesigning an engine. ”

"To use an inappropriate analogy, we initially found a small leak in the dam and plugged it with cement. ”

"As a result, the next day, the entire dam collapsed. ”

"It turns out that we are not plugging a leak, but an anthill. ”

"The embankment of thousands of miles has long been densely penetrated by anthills. ”

"That's the magnitude of the problem at this stage. ”

In the end, Zhu Mingyue nodded heavily.

"Therefore, I personally have no objection to the 927 project. ”

"In the case of Chief Engineer Zhang, Academician Zhang falling, I have the responsibility to take over the baton. ”

"But in my experience, such serious defects are difficult to solve in a short period of time, in order not to affect the country's subsequent space strategy, 927 is also a painful choice for big leaders, a choice without a choice. ”

"But that doesn't affect our determination to go all out. ”

"Do it when you know you can't do it. ”

"I know it's hard to do it, and I try my best to do it. ”

"Since its establishment, the 17th Institute has been moving forward with a heavy load. ”

Zhu Mingyue got up and raised his right arm.

"Li Zheng, Lin Yujing. ”

"Welcome to the China Aerospace Propulsion Research Institute. ”

Li Zheng shook his hands with Zhu Mingyue, and shook them vigorously: "Do it!"

Lin Yujing was much calmer when she shook hands, and asked thoughtfully: "I have a little bit to figure it out......"

Zhu Mingyue nodded with interest: "Please speak." ”

"Why do you have to exhaust?" Lin Yujing frowned and rubbed his chin in a good manner, "The so-called exhaust gas in the pre-combustion chamber, there is still a large amount of excess hydrogen in it, why waste it? Isn't it good to inject it into the combustion chamber? Isn't the overall fuel utilization rate of the rocket higher?"

Zhu Mingyue glared when he heard it: "Your mother really didn't tell you?"

"No ......"

"Then you won't be able to take over her class in a few years...... Zhu Mingyue nodded again and again and explained, "Of course the design you said exists, and it is the optimal design, our YF-100 kerosene engine adopts this design, not only full combustion, but also the air pressure in the combustion chamber can be doubled." However, when it comes to hydrogen-oxygen engines, which have higher requirements for structure, parts, pumps and materials, we can't challenge the highest difficulty at the beginning, so we use a gas generator cycle that needs to be vented. ”

"Hmm......" Lin Yujing breathed a long sigh of relief, "This is smooth......

"Originally, Secretary Zhao was blowing you so much, but I still didn't understand it...... Now I'm completely on board. Zhu Mingyue pursed his lips and nodded repeatedly, "18 years old, my God...... After so many years of education, the education system can be regarded as cultivating people like you. ”

As soon as Zhu Mingyue finished speaking, he quickly turned his head to Li Zheng: "Of course there are ...... like you." It's you, I said the wrong ......"

"It's okay, I'm used to it, I'm used to it......"

"Okay, given your level, don't go to the test team. Zhu Mingyue arranged this, "A temporary fault investigation team will be set up soon, and there will be someone who is definitely enough to be your teacher to serve as the team leader, you can follow him directly." ”

As he spoke, there was a distinctive, dense knock on the door behind him.

Knock knock, knock knock......

Li Zheng still has some impressions of this knock on the door, it is a sequence of prime numbers.

However, his face froze, and he had a bad premonition.

"Enter. Zhu Mingyue said.

Immediately, an old handsome face poked in: "I've been waiting for a long time, will you be able to cut into the queue?"

Zhu Mingyue was immediately overjoyed, and personally rushed over to greet people, holding the old handsome hand and rushing to the two of them: "This is the chief engineer of Du Songtao, the top expert of NASA who is rushing to get it, and he is impatient with rockets such as Zhizhi-1, so he specially invited Zhan to come to our seventeenth institute to support, and from now on, you will follow him." ”

"Ah......h

"Hmm......"

Li Zheng and Lin Yujing were originally happy.

It's not good all of a sudden.

There's a feeling that Spore People spies have penetrated into the human race, "Parasite" or something.

Du Songtao was quite happy, and when he entered the house, he made a glass of water by himself, and Youzai Youzai walked up to the two, drank the water and raised his eyebrows: "Isn't this a coincidence?" ”

Mom, this is obviously a conspiracy of the Spore People!

Looking at the strong hostility between the two, Zhu Mingyue asked, "Acquaintance?"

"Not familiar. ”

"Unfamiliar ......"

"It's easier to get to know. Zhu Mingyue said, "Then you two go out first and wait, I'll explain a few things to Songtao." ”

The two of them walked out of the office with their heads bowed.

Then he bumped into the long-haired big brother who was in front of them before.

The eldest brother stood in place in confusion: "It's been an hour...... I worked hard to get in line...... I'll give it back to you...... Why did you cut the line...... Can't you just talk to me......"
