Chapter 120 This n-ma has just reached climax... The eunuch won’t say anything anymore?
On the same day, Cao Dongming took Wang Hao to visit the Aeronautical Materials Research Institute, and talked about the issues related to the report. He also reminded him not to talk about the research done by Peng Hui's team, also for confidentiality reasons.
Even the Aeronautical Materials Research Institute cannot talk about projects that have just entered major national secrecy. It depends on the subsequent evaluation of the project and the openness of the data.
They talked about the reporting issue again.
Wang Hao is already prepared for this. He is going to talk about the methods used in the data analysis process and the calculation method finally developed.
The final calculation method is the classic part. Summarized together, you can write a top data mining paper, which is naturally no small achievement.
This kind of result is of relatively high practicality, especially for research on titanium alloy materials, and is generally not published.
Now that I can give a small report at the Aeronautical Materials Research Institute, I can make my research known to more people who can use it, and I can also make my own small contribution to the development of the country's materials field.
Cao Dongming attached great importance to Wang Hao. He arranged the report time at nine o'clock the next morning, which can be said to be the "golden time" during working hours.
At the same time, in order to make the report more "lively", he sent messages to several chat groups in the Institute of Materials Science and Technology, and specifically talked to several materials calculation experts in the Institute.
it is a pity.
Cao Dongming's face doesn't seem to be that great.
The next day, Wang Hao came to the Aeronautical Materials Institute and entered the small conference room where the report was to be given in advance. He found that there were only a dozen people sitting below.
He thought he came too early, so he asked Cao Dongming specifically. Seeing Cao Dongming's embarrassed expression, he already knew the answer.
"Okay, just a dozen or so people."
"Not a lot!"
"After all, they are all top experts."
Wang Hao comforted himself. He didn't really care. After all, he was invited here to give a report just for Cao Dongming's sake. He could leave after finishing the report.
It doesn't matter how many people come to listen.
He still wanted to drive it.
After entering, I shook hands with everyone and got to know each other. I also felt that the Institute of Materials Science and Engineering took it seriously because there was an academician who came and was also the vice president of the Institute of Materials Science and Technology.
That's the form of music.
Qu Shigang is over 50 years old and is the youngest academician of the Academy of Aeronautical Materials. He was originally a Ph.D. in computational materials. After returning from studying abroad, he entered the Academy of Materials and began to lead a team to conduct research on aluminum-magnesium alloys. He soon became
Promoted to director of the aluminum-magnesium alloy research laboratory.
Later, it entered the field of composite materials and achieved considerable results.
At the end of last year, Qu Shigang led the team to complete a major composite materials project. By the beginning of this year, he has been relatively free and is preparing for new projects.
When I saw Cao Dongming sending a message inviting people to attend a lecture on data mining, I came over with curiosity.
In fact, his curiosity was in the opposite direction.
Recently, Qu Shigang has been relatively idle. He has no projects he is working on and is only responsible for some affairs of the Institute of Materials Science and Technology. He often goes to read the news.
Then he noticed Wang Hao.
For a while, many media were reporting on Wang Hao and the "stories that had to be told" between him and Donggang University. Later, it turned into a self-examination by Donggang University, and it was found that the alloy laboratory incident had nothing to do with Wang Hao.
Qu Shigang also paid careful attention to the investigation announcement issued by Donggang University. The responsibility was placed on another core researcher in the laboratory.
"Typically, if something goes wrong, find someone below to take responsibility for it!" Qu Shigang was filled with emotion when he saw the announcement. At the same time, he also noticed the sentence, "Professor Wang Hao doesn't understand material research."
At first, Qu Shigang didn't even care about reading the news and just read it.
But his memory is very good.
When he heard that Cao Dongming said that Wang Hao was invited to give a report, he asked specifically and found out that it was indeed Wang Hao from Xihai University.
Qu Shi just read the report again and felt that Cao Dongming was very unreliable. He invited a young mathematics professor who did not understand materials to come to the Institute of Materials Science and Technology to give a report on data mining in the field of materials?
Even though this young mathematics professor has completed a lot of top mathematics research in half a year, data mining in the field of mathematical theory and materials are fundamentally two different directions. There is a correlation, but the correlation is very, very low.
So the musical form has just arrived.
He did come with curiosity, but this curiosity was 'reverse'.
…
Wang Hao didn't know that Academician Qu in the audience came to listen to the report with reverse curiosity.
Although there were only a dozen people in the conference room, one of them was an academician who was also the vice president of the Institute of Materials Science and Technology. The rest were all researchers and professors, with the lowest being associate researcher. Although the number was small, they were all elites.
I felt a little relieved.
Then he began to report.
Wang Hao's opening remarks were very interesting. He said, "I am very nervous standing here. To be honest, I don't understand aviation materials. I am a complete layman. I only have some research on data mining."
"If there are any questions in the following explanation, please remind me."
After telling the truth, he began his report, first explaining it through conventional analysis methods.
There are several conventional methods for data mining in the field of materials, including detailed analysis of experimental data, charting, probability research on digital distribution, etc.
These are also conventional means of data mining and are used in most analysis work in related fields.
Wang Hao's explanation was relatively more in-depth. He gave several very direct examples, including data on the titanium alloy manufacturing process, and listed them for analysis, which made it easy for people to understand.
"The Gift of Teaching" increased other people's understanding by 40%, and it also played a big role.
Everyone in the audience felt that after listening to Wang Hao's explanation, they seemed to have a deeper understanding of the methods that have been used countless times.
Suddenly, they became more serious.
Qu Shigang couldn't help but secretly praise, "The level is indeed quite good. These conventional analysis methods are explained just like a textbook."
Cao Dongming was sitting next to Qu Shigang. He didn't have much interest in data mining and analysis because he was not doing research in this direction.
Now it's just a matter of making up the numbers.
However, he has great confidence in Wang Hao, or in other words, everyone who knows about Peng Hui's team's project will have great confidence in Wang Hao.
The achievements of Peng Hui's team can no longer be described as luck.
Research on the compressive strength of β-type titanium alloys may lead to the creation of materials with a tensile strength of more than 1,500 MPa by luck, but it is simply impossible to create a material with a tensile strength of more than 1,600 MPa.
Not to mention, at a level of over 1,700 MPa, the odds are much smaller than winning a lottery of 100 million.
Therefore, as Peng Hui said, or as they saw with their own eyes, Wang Hao played a crucial role in the conclusions drawn from the experimental data analysis.
From this, we can judge that Wang Hao must be the top expert in the relevant field.
When he found that everyone in the conference room was listening attentively, including Academician Qu Shigang, who was becoming more and more engaged, Cao Dongming felt that it was normal.
He is a top expert in data mining. How can his explanation not be attractive?
Wang Hao spent half an hour explaining conventional analysis methods, and then entered the critical stage. He began to explain a brand-new calculation analysis method, "This method is a combination of the previous methods, and it also combines
This brand-new method can eliminate data interference to the maximum extent and expand differences."
"The most basic one uses a discrete mathematics method."
"Let's see..."
As the explanation slowly progressed, people in the conference room listened more carefully, because they found that the content became much more difficult, and it was not easy to keep up with the rhythm and understand it.
Wang Hao's professionalism was also shown at this time. He explained mathematics in a leisurely manner, deriving calculations step by step, using the final conclusion, and then transformed it into a calculation method.
"This calculation method can magnify the differences in the data. Even if there is only a small difference, it will definitely become obvious through calculation."
"We can analyze it through mapping later..."
When entering the drawing and analysis step, it becomes more difficult to keep up and understand.
When it comes to advanced function theory, more than half of the people can't keep up because they have no relevant theoretical foundation.
But even if they couldn't keep up, they still listened carefully because they found that Wang Hao's explanation method was indeed very subtle and very suitable for use in the experimental analysis of alloy materials.
This method may not be effective in other data mining fields, but it is very helpful for the research of alloy materials.
Later, Wang Hao spent another half an hour finishing, trying his best to explain in more detail.
But in fact, the effect is very small.
If you have enough basic knowledge, it will not be a big problem to understand the content. However, there are a bunch of material calculation experts sitting in the audience, and it is not so easy for them to understand some advanced discrete mathematics and function theory content.
However, many people do not understand it and are not in a hurry, because the report will have detailed records. They just need to get the records and do research slowly.
End of report.
The people in the conference room were much more enthusiastic than at the beginning.
Qu Shi just completely changed his view of Wang Hao. He cursed Donggang University many times in his mind, "Why don't you understand materials research? At this level, you still don't understand materials research?"
"This looks like a data mining expert in the field of alloy materials research and development. He is definitely a top expert!"
Qu Shigang also asked a question that he didn't understand.
Wang Hao also explained it very patiently. In fact, the problem with the form was the lack of foundation. He didn’t quite understand the analysis of advanced discrete mathematics. Wang Hao explained some basic content, and then he understood it immediately and knew that he was right.
If you don't understand advanced mathematics, you won't be able to understand the question, and you won't continue to ask questions.
So does everyone else.
At this time, Cao Dongming asked, "Professor Wang Hao, you gave several examples that are focused on the research and development of titanium alloys. So, can the following calculation method be directly used in the analysis of experimental data in the research and development process of titanium alloy materials?
superior."
"It depends."
Wang Hao replied, "In some cases it is possible, and in some cases it is not. If you understand all the contents and compare the specific research content, you can analyze which ones can be used."
He shook his head, "There are too many areas involved in this area, and I can't explain them all. Let me give you a simple example."
"For example, when it comes to smelting temperature control, it's not just about letting the metal melt. Sometimes, at the right temperature, the strength of the alloy produced may be higher."
"Look at this example..."
Wang Hao began to explain patiently again, and the explanation lasted for more than ten minutes.
Everyone in the audience listened very carefully. When Wang Hao gave examples, they understood the application of the method better.
At least in terms of melting temperature control, we know that relevant methods can be used for analysis.
After Wang Hao finished explaining, someone immediately stood up and asked, "Professor Wang Hao, can you tell me more about the cooling and quenching process..."
"this……"
Wang Hao hesitated immediately.
It’s not that he doesn’t want to say it, but he hasn’t completed the ‘general method for analyzing beta titanium alloy experimental data’.
[Inspiration value: 86.]
The data can already explain everything. He can explain some processes directly, but some processes still need to be studied carefully.
Wang Hao looked at the time and said with some regret, "When I came yesterday, Cao Dongming told me about the general analysis method for titanium alloy experimental data. I just thought about it briefly and did not complete the research, so I
There are many processes that I can’t explain one by one.”
"What's important is that everyone understands this analysis method. This is also the main content of my report here."
After Wang Hao finished speaking, he walked off the stage.
There was applause in the conference room, but everyone was very awkward. They felt like they were reading a novel and had just reached the climax and were looking forward to the next content...
The author is a eunuch!
No more writing!
It’s such a depressing feeling that I’m about to suffocate to death!
Not to mention other people, Qu Shigang also feels this way.
What Wang Hao just talked about is the core content, that is, the analysis method he has developed, and how to use it in data analysis of which processes.
It is important to know the method, and it is even more important to know where the method can be used.
result?
Say no more!
Qu Shigang had the urge to vomit blood, but Wang Hao had already said that he had not completed the research, so he could not ask the other party to say anything.
Next, Cao Dongming invited Wang Hao to have a meal in the canteen of the Materials Institute.
Looking at the time, Wang Hao left.
His flight was at around three o'clock in the afternoon. He went back to the hotel to pack up before heading to the airport to catch his flight.
