Chapter 318 (2/2)
With Li Zheng a little bit, a few lines of simplification to let people move the formula appeared.
”Probability distribution?” One has already called out, ”exactly the point probability distribution in a cylinder like.”
Li Zheng was also very moved, and finally someone could understand.
He again, finally appeared a primary school students can see the graphics.
It is a model drawing of yf-87 turbine shafting, with numerous small red dots on the surface and inside.
”There are a thousand red dots on this picture.”
”They hit the shafting in a probability distribution.”
”The more densely red spots are, the more likely problems are, the less likely they are to be.”
”I can only limit my ability to do the work here.”
People looked at the engine, which was like being hit by countless quantum, and was in a heated discussion.
Including Zhu Mingyue, he also explored dusongtao.
Before Zhu Mingyue spoke, dusongtao had risen.
”I know what you're going to say. Don't ask me. I don't have time to understand the middle ones.” ”If Li Zheng is right, will this conclusion help engine improvement?” Du asked
”The assumption is right...” Zhu Mingyue looked at the picture and couldn't help but sip his mouth. ”The root of the disease has been sent to our eyes.”
In the discussion, one raised his hand and said, ”if it is such a probability distribution, the conclusion is obvious The question is, how do we believe that the conclusion is reliable? You just said that you can verify today? ”
”Yes.” Li Zheng pointed out, ”this model is not only established for the three tests in front of the eyes, but also for every test run before.”
”In the 30000 second test run, I believe the problem has been exposed, but it is too small to reach our alert threshold.
”But I'm sure that its exposure probability is positively correlated with environmental difficulty parameters.”
”Although I know much less about the engine than the teachers present.”
”But I am confident that here I propose a hypothesis -” every previous test run, every engine, has a different degree of fracture. ”
”Maybe it was just a crack that was small enough to be invisible to the naked eye.”
”But it must exist and it is right in front of us.”
”At this point, we still have four complete engines in the factory, which have experienced different levels of testing and concluded that they are” stable operation. ”
”Now, go to the factory and take them apart.”
”There must be cracks.”
”If I can't find it, I promise to disappear from here immediately and no longer take up any time and resources.”
Finally, Li Zheng bowed deeply.
”I am sorry for being a bit of a student. I'm sorry.”
The scene was silent.
All eyes looked at Zhu Mingyue.
After Zhu Mingyue thought briefly, he looked to the maintenance team leader: ”I remember that there was a check after the test run before?”
”Yes, every time after the test run, the team leader hesitated,” and no cracks have been found. ”
”To what extent is the examination?” ”Is the machine removed?” Li Zheng asked? To what extent is fine? ”
”One was removed, no cracks were found, and the rest were fully checked for electrical and monitoring.” The team leader looked at Lizheng, ”the result of the whole demolition should be the same...”
”How do you know if you don't try?” Li Zheng asked, ”if the eyes can not see, use the magnifying glass, if the magnifying glass can not see, use the microscope, there must be, the mountain is exhausted can only work silly efforts, this is Liu Rui taught me, he said this is the spirit left by 17 old generation.”
“……” The group leader was dumb and speechless, and turned to Zhu Mingyue.
Zhu Mingyue almost did not think, and immediately made a case.
”The cost of verification is very low and worth trying.”Most people then nodded with conviction.
If Li Zheng's conclusion needs to be verified by a new engine, it is certainly impossible to satisfy him.
But if you just check the existing engine, a few hours is enough.
To make a joke, it's a big deal to have a magnifying glass.
Seeing the public's reaction, Zhu Mingyue also had a little confidence and shook his head and said:
”I'll talk about Li Zheng before I arrange my work.”
”He said he would leave if he couldn't find the crack.”
”I don't approve of it.”
”Here, I don't care what your education background is or how old you are. You are the top expert in data analysis. All your work is here. No one doubts your attitude and ability. Even if you point out the wrong direction, don't be afraid. If I've been wrong dozens of times, I won't sit here as usual?”
”Let's not meet each other, I'll say it's the same.”
”So Li Zheng.” Zhu Mingyue gazed at Li Zheng and nodded, ”can you take that sentence back? If you're wrong, you can get up and continue to work, can you? ”
The leader of the maintenance team raised his hand: ”yes You scared me out of my wits just now No need to... ”
”Li Zheng, we all want to prove that you are right.” The test group leader also nodded, ”what delay does not delay time, it is a family, where there is a road, we go where to rush, don't say that kind of words.”
”If everyone makes a mistake and has to leave, the space system may not be able to leave one person.”
In the comfort of everyone, Li Zheng also wiped his eyes.
”I'm sorry, I'm sorry I was so excited that I didn't sleep last night... ” Li Zheng giggled and scratched his head, ”take it back, don't say it later.”
”Don't talk about you. Liu Rui's eyes are straight.” Zhu Mingyue pointed to the sluggish Liu Rui beside him and said, ”hurry to have a rest. As soon as you come out, you are busy.”
However, Liu Rui's eyes were still straight. It seemed that he didn't even hear this sentence. He didn't react until the crowd burst into laughter.
Soon, nearly half of Zhu Mingyue arranged to go out.
Most of them rush to the west suburb test site, aiming at two engines that have experienced thousands of second test run and are ”stable and intact”.
A small number of them were sent to the original plant in northern Hebei to check the remaining two which had been returned to the factory for maintenance.
In fact, this work can be completely handed over to the workshop engineers, but Zhu Mingyue is ready to take up the ”magnifying glass” for long-term inspection and fine inspection. Of course, the magnifying glass here is not a real magnifying glass, but a series of measurement and control instruments.
The good news is that an engine of the original factory in Hebei Province is being opened for maintenance. The original mechanic immediately undertakes the task of taking down the machine for fine inspection. With luck, the conclusion may come faster than expected.
After a series of arrangements, Li Zheng answered some colleagues' questions. It was half an hour later.
At this time, Li Zheng seemed to have fought a hard battle, and his mind was finally relaxed after a night's stretching.
As soon as he was out of breath, he collapsed powerlessly on the chair.
At this time, Zhu Mingyue also fully understood Zhao Zhenhua's bet.
It's hard to predict the outcome, but it's worth a bet.
Zhu Mingyue got up in person and went to Li Zheng.
”Li Zheng, you also go to have a rest, we have fallen a lot of people, now we must preserve our strength.”
”Yes...” Li Zheng got up and said, ”but How can I sleep now... ”
”That's right. Let's take advantage of the waste heat.” Zhu Mingyue nodded, ”no matter how the result is, your analytical method has its value. In the next work, I have arranged for you to summarize your method systematically. When you have time, you can organize the people who do data to study and return them to the database in the form of documents, so as to provide reference for subsequent work.”
”This one will do.” Li Zheng said with a smile, ”I didn't expect that I began to suppress my thesis here.”
”No, no, no, this is too core to be published.” Zhu Mingyue, holding Li Zheng's shoulders, said, ”but its value must be higher than most papers. No matter what the results are, I will try to give you feedback no less than publishing core papers.”
”I really don't need this one...” Li Zheng said with a ha ha, ”it's enough to connect with Harbin Institute of technology as soon as possible.”
”Well?” Zhu Mingyue asked, ”if this conclusion is correct, still need them?”
”Still, and more.” Li Zhengzhen nodded, ”at most, I just found the way. If I want to go on, I must also need top-notch engineering calculation support.”
”I see. You can rest assured that the documents have been sent to the first people's court, and Secretary Zhao will personally approve them.”
Just then, Du Songtao, who had been playing soy sauce for a long time, strolled over.
”Lao Zhu, are you robbing me?”
”Well, it's all family, what's yours and mine.”
”Don't do that!” Du Songtao also laughed and shook his head, ”I can't believe it. It took a long time for my great master to talk to them. Instead, you made a lot of formulas to convince them...””Coincidence, coincidence.” Li Zheng patted Liu Rui, who was still in a daze beside him. ”Really, 99% of the work is done by him. I just played the level of an ordinary data analyst. What's more, his content happens to coincide with my work in this period of time. We'll be on the same page, and we'll get on with it. ”
”There are so many coincidences.” Du Songtao sighed, ”you can still sit still. You have to drill deep enough to feel Liu Rui's data, and then you can finish all these overnight. I have to admit that in this case, I may have been wrong about my work... ”
Just then, Zhu Mingyue's phone rang.
As soon as the connection was made, Zhu Mingyue called out.
”Are you sure?”
”OK, send pictures.”
”Check the second as soon as possible.”
Zhu Mingyue put down the phone and rushed out of the conference room.
”Don't go. Come back!”
”End of validation!”
”Zero for the second time
”Two and a half months, we have the last two and a half months!”
After a brief silence in the office area.
Cheers echoed from three floors.
”Are those machines really cracked?”
”It's a fault. Why am I so happy?”
”I thought it was magic. It was really mathematics.”
Right now.
Lin Qijing, who was sleeping in the office, suddenly straightened up.
”Well What time is it What about the people... ”
