Omnipotent Data - Chapter 436

Chapter 436

Department of Mathematics and Department of Physics.

One of the two is the foundation of all disciplines, and the other is the leading discipline of the natural sciences, both of which are transcendent.

Perhaps many people think that these two disciplines have always been in a contradictory relationship in which I despise you, you despise me, and neither accept anyone.

But in fact, the two disciplines have been in a friendly cooperative relationship since they were founded.

If you think about it, this is indeed the case. Whether it is mathematical research or physics research, it is like walking on a solitary path, isolated from the mass society, with few peers.

You can’t pretend that others understand what Diophantine analysis is, and understand what condensed matter physics contains.

Therefore, for mathematicians or physicists, Convenience has become one of the few peers who can have a common language.

Heroes cherish heroes, this is probably what I said.

Therefore, there is no situation in which the two verbally confront each other or fight in order to compete for academic status.

The two professors’ dissatisfaction with Cheng Nuo is not because of Cheng Nuo’s status as a “mathematician”, but rather questioning Cheng Nuo’s academic level.

They really don’t understand why the person sent by Director Ordin is Cheng Nuo, a guy who just looks unreliable!

But after all, Cheng Nuo was sent by the director, and the two professors had a hard time keeping Cheng Nuo aside, otherwise the relationship with the director might become very stiff in the future.

Therefore, after hesitating for a while, the older researcher called Cheng Nuo. “Who, come over and help look at some of these data.”

Cheng Nuo raised his eyes, looked in the direction of the older professor, and continued to lower his head to play with the phone.

The older professor looked helplessly at the young professor standing outside the vacuum, took the pile of experimental data in his hand, and got up and came to Cheng Nuo.

“Mr. Cheng Nuo, don’t make it difficult for us. Although I don’t know what the purpose of the director is to send you to our research group. But what I need to tell you is that the project we are holding is the first level of the Royal Academy of Sciences. If the project is not delivered on time, the responsibility will not only fall on the two of us.”

Cheng Nuo put the phone away, looked up into the eyes of the older professor, and said unhurriedly, “Professor Ording asked me to come here because I heard about your troubles and asked me to help. . Rather than being angry with you here. Just judging a person’s academic level by age, is it true that Cambridge University professors use this to distinguish people? So, just drag a 70-80-year-old beggar on the street. , You all must be respected as academic masters!”

“You…” The older professor was so angry that his beard stood up.

But being a professor is not a foolish man who doesn’t use his brain at all. A few words from Cheng Nuo were not enough to provoke them to lose their sanity.

The older professor’s face flushed with anger quickly returned to normal, and he glanced at Cheng Nuo, who was looking at him with a smile, snorted, and said, “I admit that what I just said was somewhat arbitrary, but what I said was all. Common sense.”

The elder professor handed a stack of A4 papers with experimental data to Cheng Nuo, “If you can really analyze the reason for the experimental failure within a day, you can prove that you are the kind of person who breaks through common sense. At that time, we The two will definitely apologize for the previous arbitrary decision.”

Cheng Nuo smiled. He took the pile of experimental data from the older professor and smiled happily.

“One day is not necessary, one hour is enough.”

Cheng Nuo’s confident tone kept the older professor’s heart beating.

In order to avoid being said to be looking for foreign aid, Cheng Nuo sat in the laboratory and flipped through the large amount of experimental data.

There are a lot of data, and more than 100 A4 papers have been recorded in more than 50 experiments.

The experimental data of more than 50 experiments are not the same, but the results are all the same because they all failed.

Cheng Nuo ignored the look in the eyes of the two professors from time to time, and his thoughts were completely immersed in the pile of experimental data.

…………

“Research on Preparation of Nano Ultrafine Powder by Electrohydrodynamic Technology”, this is the full name of the project.

Simply put, it is to use the electrofluid dynamics theory to be applied to the preparation of nano ultrafine powder.

Nano ultrafine powder is a solid particle material in an intermediate state between atoms, molecules and macroscopic objects. It can be used in many practical fields such as high-density magnetic recording materials, … optoelectronic materials, advanced battery electrode materials, etc.

The traditional method of preparing ultra-nano-differentials is not only costly, but also has very strict requirements on the environment and materials, making it difficult to widely promote and apply.

Once the research experiment of preparing nanometer ultrafine powder by electrodynamics is successful, it only needs to pass a simple quartz capillary tube and apply a super voltage to easily prepare nanometer ultrafine powder, and the cost is less than 10% of the original. Moreover, there are not so strict requirements on the materials for preparing nano ultrafine powders.

No wonder the difficulty factor of this project is not too high, but it is listed as one of the 100 first-level projects of the Royal Academy of Sciences.

Once this thing is made, the value it can create is not too great!

Having figured this out, Cheng Nuo knew why the two professors were so anxious.

After more than ten minutes, Cheng Nuo looked through all the data, and then recorded all the data in his mind.

Then, Cheng Nuo closed his eyes and constructed a table in his mind to fill in the experimental data one by one.

The purpose of the two professors is to prepare nano-superfine powder that meets the requirements, but after more than 50 experiments, the particle size of the obtained powder does not meet the requirements of nano-superfine powder.

In each experiment, only one-tenth of the powder can guarantee the particle size below 100 nanometers. If this is the success rate, there is no need for research.

What Cheng Nuo needs to do now is to find the problem through derivation.

There are many independent variables under the experimental conditions for preparing ultra-nano powders ~www.mtlnovel.com~, but only a few have an effect on the particle size of ultra-nano powders: DC high voltage voltage, DC high voltage frequency, experimental temperature, capillary nozzle The size of the diameter and the length of the nozzle, the pressure of the conveying melt, the resistance along the way when the melt flows in the capillary…

“Is there any draft paper?” Cheng Nuo suddenly raised his head and said.

The older professor pointed to a corner of the laboratory, “It’s all A4 paper over there. Use it whatever you want.”

Looking at Cheng Nuo’s back, the older professor touched his chin and thought deeply.

He paid attention to the time. It was less than half an hour since Cheng Nuo got the experimental data.

Could it be… he has ideas so soon?

No matter what the older professor thinks, Cheng Nuoke took a few sheets of A4 paper, took out the pen he carried with him from his pocket, and began to calculate the data on the paper:

[Let r be the minimum average radius of the ultrafine powder, o be the surface tension of the molten metal, ￡o be the dielectric constant under vacuum, be the coefficient related to the field strength, G be the amount of droplets formed per unit time, U be the DC high voltage ……】
