Study Monster Cultivation System - Chapter 318
In the morning, at nine thirty.
Looking at Li Zhengtao’s office, he found a guy drinking coffee with Du cuntao on his desk.
Stay up late and work overtime?!
How can you do such a thing?
Du Songtao walked to Lin Yujing station for the first time.
Found that Lin qiojing is also sleeping!
No, no, she’s working overtime, too?
It shouldn’t be. It’s just a routine sleep.
“Cough…” Du Songtao coughed not lightly or heavily.
No one paid attention to him.
Du Songtao had no choice but to walk to his desk. Just as he was about to wake up Li Zheng, he saw a printed report on the desk.
He put down his coffee cup and opened the report.
Then there was a stare.
And then it went faster and faster, straight to the last page.
Then there was a long stagnation.
If so
So now it should be
He subconsciously turned back and wanted to rush into Zhu Mingyue’s office.
But the pace soon slowed down again.
He still can’t do such a thing as stealing merit.
He quickly returns to the table and wakes Li Zheng and Liu Rui with his report.
Without waiting for the two to speak, Zhu Mingyue pointed to the report.
“I don’t understand the algorithm. Just tell me how sure you are.”
After a short stay in bed, Li Zheng shook his head and trimmed his hair.
“More than 95% and can be verified immediately.”
“We don’t have the ability to verify. We have to let the team of the sixth hospital come, which will cost a lot of energy.” Du Songtao waved a report and said, “I’m going to ask Zhu Mingyue to hold a plenary meeting right now. If it’s denied, we will become a big joke.”
“No, chief engineer Du.” At this time, Liu Rui also put on his eyes and stood up and said, “even if our conclusion is wrong, this matter is not ridiculous at all.”
“I see.” Du Songtao respectively patted two people and said, “wait for my news.”
Then he left the office in a hurry.
Five minutes later, yf-87 team members received the emergency meeting notice.
When Du Songtao comes back, Li Zheng and Liu Rui are finishing the report on PPT, and Lin yuejing is still sleeping.
“How about it?” Du Songtao hurried to his desk. “Do you have any problems in your report?”
“Li Zheng’s report is good. My mind is empty.” Liu Rui said blankly, “I’m full of curves now. I can’t even understand what Li Zheng is saying.”
“You do the main work. You do it.” Li Zhengcun turned to PPT and said, “and this is the field of 17 institutes. I don’t want to be too bold. A group of teachers will have a bad feeling when they listen to me…”
“But I really Now it’s hard to say a whole sentence… ” Liu Rui squeezed his eyes and rubbed his forehead. “For the first time in my life, my brain has been overloaded like this…”
“Well, I’ll decide.” Du Songtao lights up the computer and says, “Li Zheng is responsible for reporting, and Liu Rui’s name is written in front of the PPT, OK?”
They looked at each other for a while and then nodded reluctantly.
“Good.” Du Songtao clapped his hands and pulled them up. “Now, both of you go to wash your faces, take a few mouths and wake up. I’ll pour you coffee. If it can be verified as your conclusion says, then I believe –”
“at the beginning of today, Huang Er will fight back.”
……
At 9:39, the last member of the team rushed to the meeting room.
The notice only mentioned the emergency meeting without too many details and no news in advance, which filled most people with a sense of mystery.
In front of the long table, Zhu Mingyue and Du Songtao are discussing nervously, while Li Zheng and Liu Rui are leaning on the side of the projection screen, dully adjusting the projection.
At 40 minutes, Zhu Mingyue and Du Songtao nodded to each other and temporarily shelved the discussion.
Zhu Mingyue omitted those opening remarks, and after putting down Du Songtao, he spoke directly.
“Chief engineer Du digs out breakthrough results in internal data analysis.”
“There are so many things involved that I didn’t have time to look at them carefully.”
“Let’s listen to Li Zheng’s report directly, discuss its accuracy on the spot, and arrange the follow-up work.”
People in the meeting room could hardly conceal their disappointment.
During this period of time, Du Songtao has indeed put forward some ideas at the regular meeting, but either they have been proved as no or they have no conditions at all.
Although he is an expert in satellite, he is still too inexperienced in the engine line, and he seems to be on paper.
To put it bluntly, it’s like two people shooting lol with their mouths. How can I get out of position? I use Q you and so on. According to his self logic, it is barely tenable, but in practice, it’s not like that.From Zhu Mingyue’s words, it’s not hard to tell that he has clearly set aside his responsibility, and is simply dragged to the meeting by Du Songtao.
That’s what happens to laymen. It’s a waste of everyone’s time.
After seeing that Li Zheng was the reporter, most people were more disappointed.
Although in the end, can you really do such a funny thing? Listen to a high school student plan here?
Li Zheng, on the other hand, didn’t notice this at all. He simply cut his hair and stood up.
In order to cheer up, he even wet his hair, now belongs to a kind of greasy handsome, some overtime old programmers look like.
“First of all, let me make it clear that this work is not entirely done in our group.”
“It was Liu Rui and the members of each group who completed 99%, and I only finished the last 1%.”
“Let me briefly describe the process and conclusion.”
Li Zheng said, press the controller, the screen immediately showed a graph.
“This is a suspicious frequency curve.”
“There are thousands of sections of this type of suspicious curve in each test run.”
“I’ve been working on finding its eigenvalues, using some kind of algorithm to eliminate the interference term, finding the most suspicious part, in-depth research.”
“But when it comes to engineering calculation, my personal ability is limited and I have never found a reliable method.”
“At this time, Liu Rui sent these These, and these… ”
Li Zheng said a few consecutive points on the controller, a suspicious curve tiled on the screen.
“We have analyzed and studied these curves.” A group leader raised his hand and said, “Liu Rui’s work is very hard, but we haven’t found any reliable conclusions according to these clues. They are probably the normal vibration noise of the engine during operation.”
Li Zheng nodded.
“Yes, just take out one of the analysis will be like this, just periodic, not light or heavy, not deep or shallow.”
“If we analyze in isolation, it is like solving an equation of 12 variables according to one line of formula, there will be no result.”
“So we need to make at least 12 formulas and combine them.”
Li Zheng clicks remote again.
The tiles are stacked together.
The audience then looked sideways, many disappointed people followed the spirit.
All of us here are experts in this field. Although they are just a pile of curves, they have already felt the periodicity and correlation contained in them.
Li Zheng then hit again, along the overlapping shadow of 12 curves, a clearly marked red curve appeared, and the relevant matrix and its dense mathematical expression appeared at the bottom.
“That’s the solution.” Li Zheng circled more than half a page of mathematical symbols on the screen, “teachers can have a simple look, we have no clear query to turn the page again.”
At this point, there are not many people who can understand.
One of them, a young engineer, raised his hand.
“We have tried similar work, but you have to know that from those suspicious data that Liu Rui finds out, if you randomly extract any 12 of them for correlation analysis, there will be some conclusions. Such an analysis method does not necessarily prove anything. Considering that he has summed up nearly 200 curves, it is not even possible to prove anything.”
“These 12 items are not randomly picked up by me, but refined by the algorithm of optimized fault model.” Li Zheng explained carefully.
“According to the parameters I input in the system, it can extract 1, 2, or even 100. 12 is just a number that I can easily express here.”
“In the actual analysis, the final parameter I choose is 67, which is roughly equivalent to solving the 67 element equation.”
“Of course, my current expression is still very shallow, which involves the professional content of machine learning and data analysis. If the teacher is interested, he can read three papers published by the 11 institutes before.”
The engineer shook his head and said, “I know you can’t make a detailed statement here, but the problem is that this step of argument is very important. If we don’t convince everyone here, it will be very difficult for us to accept your later conclusion.”
Li Zheng confidently nodded: “it doesn’t matter, my conclusion can be verified by actual measurement.”
The engineer said, “do you mean, let’s build another engine based on your conclusion and go for a test run? I don’t want to offend you, but we really don’t have the time and resources to do this… ”
“We don’t need to rebuild or test drive. We can verify it today. At most, half a day is enough.” Li Zheng was helpless and said, “in fact, I didn’t expect to let you accept my conclusion with such a simple report. This report only gives you a reason to examine my conclusion. ”
“……” The engineer shook his head, raised his hand and said, “you go ahead. Let’s assume that your fault curve holds.”
“Thank you for your tolerance.” Li Zheng said, “to be exact, this conclusion is not a fault curve, but a curve describing the fault curve and an equation describing the equation, which is equivalent to reducing the fault analysis by one dimension and resolving it into a pure mathematical problem. Based on this, we further calculate and dig out this -“As the screen turned, a more terrifying matrix map was presented that no one could understand.
“This is the mathematical description of the final failure.” Li Zheng pointed out, “I am not showing off the mathematics level to confuse you, but I just want to show more reliable arguments and deepen the reasons for everyone to prove my conclusion.”
“Then, let’s just give this description a little bit…”
“It’s like this…” he said
“Although it is difficult to understand, it is actually one of the mathematical expressions of two-dimensional projection of the fault point of the shaft system…”
“Now We should restore this projection to the shafting according to the structural parameters of the shafting… ”
“In short, it is to increase the dimension again…”
“You can understand this process as a computer operation process. First, we can convert the characters we input into binary sequences, and then output them as the characters we can understand…”
“Don’t show this expression, I’m not really in the pack…”
“The final mathematical expression is very simple, I believe that you can understand…”
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… “
