Learning Demon Cultivation System

"No, I understand basically everything." Li Zheng waved expectantly, "Come, come, let's do some big work."

"???" He Zhongrui was taken aback for a moment, then glanced at the data table again, "You...you think you're all right after just reading two pages?"

"I still read a lot." Li Zheng bit the bullet and explained, "It's just that I have been exposed to a lot of knowledge before, and I can jump over if I can jump."

"No..." He Zhongrui scratched his scalp and said, "Where can you teach me about aerospace engines?"

Li Zheng couldn't say anything, he just raised his eyebrows and said, "Okay, Brother Rui, let's do some big work and try it first."

Seeing his playful smile, He Zhongrui was a little impatient: "Li Zheng, how capable you are to do great things, in your current situation, do I dare to give you work?"

"Ah, this..." Li Zheng was in a dilemma.

He didn't blame He Zhongrui at all, as common sense inferred that there was indeed something wrong with him.

But how to explain this...

At this moment, there was a sneer suddenly.

"Test him." Lin Yujing sat in front of the computer, scanned the document and said, "Just test him casually."

"Wonderful." Li Zheng stared, and hooked He Zhongrui again, "Test me."

"..." He Zhongrui was naturally too lazy to waste this time, let alone being sleepy, but considering the complexity of the identities of these two people, he finally nodded, "Li Zheng, work is really tight now, if you answer If you don’t come up, you can either go back to continue studying, or do document work with Xiaolin, at least don’t increase our burden.”

"Definitely." Li Zheng's expression gradually became serious, "Teacher He, let's ask the questions directly to save time."

"It's a difficult question." Lin Yujing booed from the side.

"Haha..." He Zhongrui smiled wryly, "I really want to give you face...but since Xiao Lin has said so...I'm not polite."

"Please……"

He Zhongrui rubbed his forehead and thought about it.

Several people in the office also frantically peeked over.

It's just a high school level, and he is acting wild in the field of master's and doctoral degrees.

It's time to show the dignity of a schoolmaster, team leader.

Let Lin Yujing take a good look at the level of the test group.

The word "aerospace engineer" is not called for nothing.

As for He Zhongrui, even though he was asked to ask difficult questions, he is a doctor-level existence after all, and he would be able to ask difficult questions that the other party would not be able to answer as soon as he came up, so he would inevitably bully the juniors.

On the other hand, he also wanted to take the opportunity to check Li Zheng's level.

Therefore, he asked a question of balance and balance.

"Principal Failure Modes of Pumped Engines."

Li Zheng replied immediately.

"There are a total of 12 data summaries."

"1. The joint is leaking."

"2. The starter is abnormal."

"3. Leakage of hot gas."

……

"12. The valve is working abnormally."

He Zhongrui stared slightly, and then asked, "Where do the failure modes correspond to?"

"Leaks, corresponding joints, welds, cracks, rotary seals..."

……

"Foreign objects, counterpart injectors, turbo pumps, airflow holes."

He Zhongrui stared at Li Zheng for a long time with a sullen face before asking, "Have you memorized it before?"

Li Zheng could only smile back.

Who the hell is it okay to carry this thing?

"You don't need to memorize this." Li Zheng explained, "After you have a comprehensive understanding of the engine's structural components, if you raise a fault, you can naturally analyze the possible parts of it. Just understand."

Not only He Zhongrui, but even the other people who were furiously peeping were a little ashamed.

Fuck you, you just have to memorize it, so understand it.

They still don't know that Li Zheng, who has gone through two competitions and a series of thinking exercises...

The brain has already become strange.

"..." He Zhongrui asked after struggling for a moment, "Please list a few main fault characteristic value parameters."

"Flow, pressure thrust, temperature, vibration, speed, stress, torque..."

"Enough." He Zhongrui raised his hand and said, "Tell me briefly how to choose the eigenvalues."

"Select n characteristic parameters xk from the existing N characteristic parameters xi, and form the optimal characteristic subset under the meaning of a certain index function J, among all possible alternative characteristic values..."

He Zhongrui interrupted Li Zheng again, and asked again: "What is AWSSA?"

This time Li Zheng really thought for a while before saying: "The adaptive weighting and averaging algorithm is one of the algorithms for analyzing and predicting faults based on engine characteristic signals."

He Zhongrui turned around suddenly, picked up the pen and paper on the table, and wrote out two lines of calculations that people with more than 60% hair volume would never understand.

"The upper part is the mean value of the detection parameters, and the lower part is the variance. Can you calculate the Grubbs statistic?"

"Wait a minute..." Li Zheng took the pen and thought for a while, and wrote down a simple formula, but only people with a volume of less than 70% could understand it. Then he took out his calculator and rubbed his hands, "Teacher You go to rest for a while, I will start counting slowly."

"No need..." He Zhongrui pressed Li Zheng's arm, and his whole face showed a kind of innocence that doubted life, "Why do you even know fuzzy mathematics?!"

"It's just..." Li Zheng said hesitantly, "I understand a little."

"..." He Zhongrui looked at Li Zheng, as if the words "why" were about to shoot out of his eyes.

After a long time, he let go of his hand and said to a person in the back row.

"You teach him the process of analyzing engine test data."

"……it is good……"

He Zhongrui looked at Li Zheng, then at a table of documents, and finally asked, "Why..."

Suddenly there was another laugh.

"Huh..." Lin Yujing covered her mouth and smiled, "Now you know how difficult it is for me... Who has learned this before."

Chapter 292 In fact, the most feared thing about eating is procrastination. In fact, she is the only audience in the audience

In the lounge, He Zhongrui was not sleeping, but was on the phone.

Excited to call.

"Double competition champion? No wonder!"

"Yes, yes, but his background is better than what you describe."

"It should be self-study a lot of professional content in advance."

"To be honest, his ability should go to the technical team, after all, that's the most important thing."

"Hey, let's get tired when we are tired. It's not a day or two. The secretary said everything. At this stage, all work is carried out around zeroing. As long as the task can be completed as soon as possible, you can clean up my staff." OK."

"Lin Yujing? Transfer her back together?"

"No, no, Lin Yujing's work experience... There is still a lot of room for accumulation."

"How long? I was thinking, it might take more than half a year..."

"All right, let Li Zheng talk to Zhou Chenglong first."

"What, one o'clock in the afternoon?"

"Fuck, another meeting."

"No, no, no... I didn't mention you."

After putting down the phone, He Zhongrui rubbed his heart and went to bed.

He didn't intend to dismantle these two people, the main reason was that Li Zheng was indeed too outstanding, and he could undoubtedly play a greater role in the technical team.

As for Lin Yujing.

This is an artifact that increases the efficiency of the brothers collectively by 30% and reduces sleep time by 50%. Can this let her go?

……

At the beginning of 12 o'clock, the cleaning lady knocked on the door.

"The meal is ready."

Hearing this, the three engineers on duty in the computer room stretched one after another.

In the final analysis, they are all just completing tasks, far from being devoted.

After all, the work in front of him is difficult to produce results.

These test data have been analyzed a long time ago, including manual analysis, software analysis, and mathematical analysis, and now they have been analyzed with stricter standards.

This is what Chen Hongbing insisted on. He believes that since a problem has occurred, there must be a certain feature in the thousands of tests before, and catching this feature will also catch the key to the failure.

Shen Tinglan agrees with this idea, but opposes letting the people in the test team play with these old data at this stage.

What she meant was that since no problems were found in thousands of tests and analysis, it would be very difficult to find them now, and even if it was possible to find them, it would not be possible to find them simply by working overtime.

Just like checking in an exam, they have checked Huang Er's paper many times, but they still made mistakes in the end.

If one is compared to the person who made the test, then the mistake in front of him is obviously a mistake that has broken through the thinking of the test taker, and it is meaningless to check it again.

Instead of this, it is better to add new ideas and do it again.

Or simply bring in outside experts to re-examine with their thinking.

In short, let the test group work hard on these now, it is better to go to other groups to support.

Even if you take a good rest for a few days, you can develop more energy to deal with the follow-up heavy tests.

However, in the end Chen Hongbing insisted on his opinion.

According to his words, it is a necessary attitude to review things first, and he needs the testing team to carry out "past error correction" work to express an introspective attitude to his superiors and colleagues, which is also putting pressure on the Sixth Academy , forcing them to do the same amount of error correction.

In this way, the people in the test group are just pitiful, and they have to work on these difficult things in two shifts.

Of course, they themselves are aware of this, so although the work intensity is high, they will go to eat as soon as the aunt calls, and change shifts when it is time to change, so they will not be too involved.

but……

That was the state of a day ago.

At this moment, after receiving the signal to eat, although the three engineers stretched habitually, they didn't get up.

The so-called straight man means that due to limited experience, when communicating with girls, he can only find the most direct and basic reasons.

such as.

"Drink more hot water."

"Don't eat cold ones, your stomach hurts."

"sleep early."

On this basis, I can't think of anything more, not even asking "Do you have a dream?"

But for the three engineers in the computer room.

The aunt's call to eat is undoubtedly a golden opportunity to strike up a conversation.

Not only gold, but diamonds, the strongest.

think about it.

"Little Lin, do you want to eat?"

With just 5 words, the conversation that is difficult to say on weekdays is naturally completed.
