The country is unparalleled, I have achieved hundreds of millions

"First of all, I would like to thank Jinger for providing me with the most important inspiration, which allowed me to find the idiosyncrasy in the depths. This idiosyncrasy, this period of turmoil exists in the form of three different engines, after thousands of experiments , there has been turmoil.”

"But because the data is too huge, and I don't have enough data that can be used as a reference, I barely found a few points, and the calculated data can't be recognized by everyone, and I can't find the real law."

Regarding Yun Yongan's explanation, everyone nodded approvingly, "This is the most troublesome part. If the amount of data is not enough, there may be too many algorithms. It's like one, two, four, three numbers."

"They can either multiply by two each time and the fourth number is eight, or they can add one for the first time, add [-] for the second time, add three for the third time, and seven for the fourth number."

"Indeed, because of the insufficient amount of data, we cannot be sure whether the laws we found are true, but not true under certain limited conditions, so," Yun Yongan turned the page of the ppt.

"I found a large number of abnormal oscillation points through Jing'er, combined a large amount of data, and successfully created a data failure model. Now, I can find the failure data by inputting the corresponding parameters."

"Then I listed several multivariate equations based on these vibration data, and finally found the really abnormal part of the engine."

Yun Yongan pointed to the turbine of the engine in the picture, "This is where the engine fails. There is a problem with the turbine and bearings of the engine. To be precise, it is because the material quality is not enough. There has been a problem from the very beginning. It's just this problem. It was a small problem, and it gradually expanded in the back! Until the time of lift-off, the engine stalled."

"This!"

Everyone looked at the dense calculation formulas on Yunyongan's ppt, and fell into a deep silence.

"I'm sorry," Yun Yong'an clapped his hands, "I don't know enough about engines. I can only convert all the experimental data into mathematical language, and then solve it mathematically."

"Connect these data first, then do calculus processing, and micro..."

"Then, we use mathematical tools to project these from the numbers onto the number axis, and through the number axis processing, we get this..."

"This data is not enough, you need to increase the dimension first, and then micro, and you get this..."

Yun Yongan went to Jiangsu and Zhejiang with great interest, not noticing the expressions of the other people in the conference room, which had already changed into the appearance of Abba Abba.

"This is very basic mathematical knowledge?" Yun Yongan was very puzzled, "Zhou Sun, can you understand?"

Zhou Sun smiled wryly and shook his head, "I can understand, but I can't understand, you speak too fast, it has exceeded the limit of my thinking, please speak slowly, give everyone a little time to think, they are all Wanli Pick out the cutting-edge talents who come in, and if you are satisfied, they should be able to keep up with your thinking."

Zhou Sun's voice became lower and lower. Obviously, he also found that he overestimated the level of other people and underestimated the difficulty of the algorithm Yun Yongan created.

"Forget it, let me continue."

Yun Yongan swiped through more than 20 pages of ppt in a row, turned to the final mathematical expression, and displayed a point diagram.

"This is the point of failure during vibration. Ninety percent of it is on the bearing, and one percent is on the turbine. The paint insulates the temperature and also insulates the metal from damage."

Yun Yongan vowed, "It is very easy to verify my conjecture. If I remember correctly, there are still three engines in the engine research base. They have been tested and disassembled for research, but they have not found any. question."

"Because when you disassemble and study, you will not scrape off the precious paint on the surface. Even if you do scrape it off, because the process of removing the paint will cause damage to the internal metal, you cannot be sure whether it is during operation. problem."

After Yun Yongan finished speaking, everyone looked at Li Xinlong in unison. Only he had the right to decide whether to dismantle these engines.

Without the slightest hesitation, Li Xinlong made a decision directly: "Tear it down, tear it down, if you can't find any problems, these engines will eventually be discarded. After removing all the precious materials, they will be enshrined in the Science and Technology Museum as models."

Everyone suddenly realized, and nodded in unison. Indeed, if the failure point cannot be found and cannot be repaired, these engines have already lost their value. In order to make their knees work hard, destructive inspections should also be done.

It was getting late, but it couldn't stop everyone from exploring the truth.

Resonance, dialysis, multi-directional friction, reaction removal of reactants...

Because this kind of paint is a permanent paint based on stability from the beginning, it took a lot of effort to remove it from the turbine blades and bearings perfectly.

In order to ensure rigor, they used different removal methods in different parts.

Four in the morning.

The testing of the three engines was basically completed, and hundreds of pictures filled the entire conference room.

Li Zhenhua stood up and summarized the report: "After excluding the interference items caused by improper paint treatment, according to the integration of the nine pictures of 670, it can be concluded that the turbine and bearings hidden by the paint, especially the bearing part, did produce a large number of cracks."

"The number of these cracks increases rapidly with the increase of engine starting time, which conforms to the mathematical law proposed by Yun Yongan, and we have found the point of failure!"

The people, who were physically and mentally exhausted, couldn't help cheering after hearing the news. Along with the cheering, some people even wept with joy.

"Great, finally found it!"

"There are still three months, enough!"

"Yong'an talent, number one in the world!"

……

Unknowingly, everyone's shouts gradually became unified, and in the empty laboratory shed, the shout of "Yong'an talent, number one in the world." resounded through the sky.

Yun Yongan was lifted high by a group of researchers, thrown up, caught again, and thrown away again!

Yun Yongan did not expect that researchers who are already senior intellectuals would use such a rough way of celebration. In order to prevent them from accidentally flashing their waists, Yun Yongan had to use a lightness technique to make himself lighter than a girl .

After some commotion, everyone was exhausted and collapsed on the ground, unable to move.Yun Yongan patted the dust off his body, walked to the front of the stage and loudly reminded everyone.

"Everyone, this is just a small step. What Zhou Sun said is right. Even if there are special coatings, it is not so easy to manufacture a material that can withstand high and low temperatures at the same time. We still need to work hard." ah!"
