Wang Hao felt very uncomfortable about being questioned by Ding Zongquan in the experimental meeting just now. When he thought about it carefully, he felt that he was being polite.
There is a saying that ‘there is a specialty in every profession’.
In a R&D team, everyone performs his or her own duties. He is responsible for data analysis and mining of experimental data. Because the experiment is about to start, he will also make process adjustments based on his analysis results. Naturally, there is no need to do it again.
Just demonstrate it, state the results directly, and correct the process.
He didn't expect that an expert would come to ask questions.
If the people present are all experts in the field of mathematics and computers, he would not mind a brief explanation, but for a large number of experts in materials science, it would be very difficult for him to explain.
He didn't take out the report at first, just because he knew that there were only two or three people present who could understand it.
Two or three is too much.
It is very likely that only Wan Yiming can understand it. Shi Guifang also has a PhD in materials calculation, but his level is relatively worse. As for others, it is simply impossible.
‘Crossing a line is like a mountain’, especially in the academic field.
It is not easy to understand the different research directions in a single subject field. It is simply impossible for experts who study materials to understand advanced mathematical computer problems.
If the other party is a member of the metal laboratory, Wang Hao will be relatively polite. After all, the other party is really considering the experiment.
However, the other party is just a review expert from the Materials Department and is not a participant in the project. There is a high probability that he will not really consider the project. It is very likely that he just wants to say a few words at the meeting to show off his talents.
That's all.
It's OK for experts like this to point their fingers. If they want to talk about Peng Hui's work, no one will say anything more and will listen patiently. They are all experts in the field of materials research and development, and they are also project leaders.
It can be said that the fields are repetitive.
But to talk to him about data analysis is to use his fingers in the wrong place.
They are not going in the same direction at all.
Wang Hao felt that he had a good temper. He did not fall out on the spot, but implicitly stated one thing - it would take at least a week for the other party to understand the contents of the report.
This is not true.
Because it would be impossible for the other party to study the report and understand it in a week, and they might even have to make up for the relevant content because they don’t understand certain basics, which is simply not something that can be accomplished in a short time.
The data analysis he performed involved many professional methods, and the final calculation content also involved advanced mathematical problems, such as functional analysis, discrete mathematics and probability research.
These contents are very difficult for non-mathematics professionals to understand.
Materials experts are indeed very powerful, but they only conduct research in the application field, which is completely different from mathematical research.
To use a less polite metaphor, it is like an undergraduate majoring in chemistry theory. After graduation, he has been engaged in junior high school chemistry education for more than 20 years. Suddenly, he suddenly had a whim and wanted to understand a difficult professional mathematics topic at the graduate level.
.
Isn't this funny?
Even if the world's most famous mathematician is invited to give a lecture, it's impossible to understand him!
…
On the other side, Ding Zongquan felt very angry.
After the meeting, he did not leave the metal laboratory. Instead, he found an empty office with the report in his hand, obviously trying to figure it out.
He was just angry.
As an expert in the field of alloys, he is treated as a guest wherever he goes. As for the field of alloy manufacturing involved, he believes that no matter what the content is, it belongs to his own field of knowledge.
Regarding projects related to alloy manufacturing, what questions do you have?
He obviously meant well, but in the end he was beaten back. He was beaten so hard by a young man that he couldn't get off the stage. Thinking about it, he felt very depressed.
Ding Zongquan still knew the difficulty of the content of the report. After a few glances, he knew that it contained some content that he didn't quite understand, so he called another expert, Lu Daxiang.
The relationship between Lu Daxiang and Ding Zongquan has always been very good, and they are old friends who have known each other for decades.
Lu Daxiang followed him into the office and persuaded him, "Old Ding, tell me, why are you competing with a young man?"
Ding Zongquan said angrily, "Young people like this think it's great when they have some achievements, and they even say on the spot that I don't understand."
"I don't understand? I, Ding Zongquan, have lived for more than fifty years and have published several papers on material calculations. What can't I understand?"
"Yes, yes~~"
Lu Daxiang quickly followed up and said a few words. He was also very curious about the content of the report, so he simply studied it with Ding Zongquan.
Half an hour later, Lu Daxiang gave up. He sighed and said, "I'm right, it's too difficult. There's a lot of professional mathematics in it, but I don't understand it anyway."
He decided not to waste time and left the office.
Ding Zongquan was still staying inside, but he found that it was impossible to make any progress by himself if he studied.
After another half an hour, he walked out with a dark face, and immediately decided to go back to the hotel and continue to stay in the laboratory, feeling embarrassed when he met anyone.
He still remembered to hand the report back to Li Jiping and ask him to forward it to the laboratory.
Cao Dongming is staying with Li Jiping.
After Ding Zongquan left, Cao Dongming couldn't help but laugh and said, "Academician Li, you said that this Gong Ding is the same. He insists on competing in mathematics with a person who studies mathematical theory... This is just unthinkable!"
"When he and Lu Daxiang went in just now, I saw how difficult it is to study mathematics. If Wang Hao can achieve results in this area, he is one of the smartest people in the world."
"For such a genius, if he wants to say that you don't understand certain mathematical problems, then you definitely don't understand."
"Ding Gong has been doing material research for more than 20 years. Doesn't he think he has become a math expert?"
Li Jiping felt something was wrong when he heard it. He thought about it carefully and immediately burst into laughter. He pointed at Cao Dongming and said, "You have a mouth that hurts people. It's really ugly. How can you make it? You are treating yourself like an elixir."
He shook his head, changed the topic, and asked, "What do you think of tomorrow's experiment?"
Cao Dongming hesitated and said, "Wang Hao is indeed very capable. You can tell by looking at his reports. But, alloy research, this thing... is hard to say."
He's not sure.
In terms of personal judgment, he felt that Wang Hao was trustworthy. If he improved the process according to Wang Hao's method, the strength of the finished product might continue to improve. On the other hand, past R&D experience told him that a process based on analyzing data would
Improvements are unlikely to improve the finished product.
His R&D team also has professional data mining talents, and they all have PhDs in materials computing or mathematical computer science from top domestic universities and prestigious overseas universities.
However, their analysis of experimental data can only serve as a reference, and they will not directly improve the manufacturing process based on their conclusions.
Li Jiping also nodded and said, "Peng Hui respects Wang Hao very much when it comes to material experiment data analysis. I hope they can achieve results, and it is not in vain to stay here for two more days."
"Let's see tomorrow."
Cao Dongming also nodded. They are both experts in the field of alloy material research and development, and their judgments are basically the same.
Their research and development experience shows that there are no shortcuts in the research and development of alloy materials.
As long as the experimental data is analyzed, the process can be improved and the correct manufacturing method can be found?
It sounds outrageous!
…
The start time of the experiment is set at nine o'clock in the morning.
The materials laboratory did not start preparations at nine o'clock. They had already been busy working on it the day before. In order to allow the experiment to proceed smoothly without any problems during the process, some people even slept in the laboratory and operation room.
Peng Hui also fell asleep in the experiment.
He went to bed after the early morning inspection. He got up at 5 a.m. and called someone to test the raw materials again. The most important thing was the test of titanium powder.
Titanium powder is the powder of ground titanium metal.
This is the main material of titanium alloy, and the impurity content in it will directly affect the performance of the alloy. The impurity content must be low enough to ensure that it does not affect the experiment.
At eight o'clock, all the equipment in the laboratory operation room began to operate, and some preliminary work also began.
The members of the expert review team came to the laboratory at nine o'clock.
Wang Hao came a little earlier, just ten minutes earlier, because he knew that he wouldn't be able to help much. He couldn't gain any inspiration points by looking at the experimental process again, so there was no need to come early.
While the experimental manufacturing was in progress, Wang Hao simply went to the data analysis office and told Wan Yiming about the content of the analysis report and the field of data mining.
"Data mining is a very difficult field. I feel that every analysis is a brand new research."
Wan Yiming nodded with deep sympathy.
Wang Haodao, "There are many ways to do data analysis. I will think about every method I know to see if it is applicable."
"If all methods fail to solve the problem, you must think of new methods."
"Your project is like this. At the end, I used functional analysis to study the volatility of the data. I also used probability statistics to set up a set of values to analyze the probability."
"Both methods contributed to the final conclusion."
Wan Yiming listened and quickly took notes. His attitude was very serious. With the successful experience last time, in his eyes, Wang Hao is a super expert in data mining. Analyzing the experimental data can help realize the research.
A qualitative breakthrough and a few words of guidance will definitely benefit you a lot.
When someone exudes trust and even admiration, everyone is in the mood to say a few more words.
Wang Hao was very patient and told Wan Yiming more when he had time. "For example, in alloy materials projects, the most important thing to study is the process. We have no way to study new processes through data, but we can filter out
Those effective processes, and study the role of each process."
"These can all be reflected in the data, such as..."
"Bala bala~~"
Wang Hao was discussing with Wan Yiming when he heard the sound of clapping from beside him.
It's Cao Dongming.
Cao Dongming clapped his hands twice and said with a smile, "Professor Wang Hao, that's wonderful!"
"I'm so sorry. I just listened for a while. I never paid attention to data analysis work before. Now after listening to your explanation, I know that this aspect does have great potential and is very important for research."
Wang Hao nodded.
Cao Dongming asked, "Professor Wang Hao, you are very interested in the research and development of titanium alloys, right? I have been doing research and development in this area, and I have five projects under my hands. I am really busy."
He sighed and shook his head, "I would like to ask, do you have time to do some analysis on other titanium alloy research?"
"Uh~~"
Wang Hao shook his head, "Not interested."
"Ah?" Cao Dongming didn't understand.
Wang Hao shook his head and said, "What I said just now is that I have no interest in titanium alloy research and development." He explained, "I did data analysis for Professor Peng Hui because of Professor Xia Guobin's introduction. To be honest, I am not interested in alloy manufacturing."
I don’t understand it at all, and I don’t have much interest in it. I mainly do mathematical theoretical research.”
Cao Dongming didn't care about Wang Hao's rejection. He asked with interest, "What research are you doing recently? I know your Mersenne primes and Atting's constant."
"It's also related."
Wang Haodao, "I am currently planning to focus on studying a new mathematical method to solve interesting numerical problems in mathematics."
He said patiently, "For example, you should know the Kratz problem. There are related 3x+3 problems and 3x+1 problems. These simple-sounding numerical problems seem like games, but dozens of
It has not been proven effectively over the years.”
“Many mathematicians have done research and concluded that ‘don’t try to solve these problems’, or simply ‘mathematics is not mature enough to solve such problems’.”
"These conclusions can also show that it is impossible to solve such simple numerical problems with existing mathematical methods, so I hope to find a new method."
"Oh~~~"
Cao Dongming nodded slowly while listening, with a "a bit profound" look on his face. Then he was silent for a moment, then patted Wang Hao on the shoulder and said two words, "Come on!"
…
The new experiment was carried out until noon and only one-third of it was completed, but no one involved in the project took a break. They had to insist on completing the experiment.
Progress slowly step by step and complete slowly.
Peng Hui and other researchers kept an eye on the manufacturing progress throughout the process, constantly giving instructions and sometimes even doing the operations themselves.
Others have it much easier.
There is no point in them staying in the operation room, so they might as well just wait in the laboratory.
At noon, Wang Hao also leisurely went to the cafeteria of Xijing Jiaotong University to feel the difference between the cafeteria here and that of Xihai University.
Later, I found that there was not much difference, and the food tasted very average, so I could only give a "barely qualified" rating.
Of course, it’s hard to expect that the big pot rice served in school will be very delicious.
At 3:30 in the afternoon, the finished product was ready. The experiment took much longer than the last time, mainly because a capacity cooling step was added.
After the finished product comes out, it waits for natural cooling and then is tested.
Everyone in the laboratory was very nervous and somewhat expectant. Many people simply waited at the door of the testing room.
Wang Hao continues to stay in the data analysis office.
He explained the analysis method to Wan Yiming so that Wan Yiming could understand it better.
After two or three hours of explanation, Wan Yiming has almost understood everything, but there are some very difficult parts, so he still needs to come and ask.
When the time was almost up, Wang Hao and Wan Yiming walked out together and saw Peng Hui, several other researchers, and three expert reviewers standing there waiting.
After asking, he learned that there was an expert named Yue Zhiquan who was very knowledgeable in material testing, so he simply went in to help with the testing.
Peng Hui waved and greeted Wang Hao. His face was obviously a little nervous, and he kept looking at the door of the testing room.
"Professor Peng, don't worry, the results will come out." Wang Hao said comfortingly.
Peng Hui was indeed a little nervous.
Nervous because of expectations.
When the final product was manufactured, Peng Hui relied on his own experience and saw that it was unusual at first glance. He said, "I have a hunch that the intensity this time will exceed 1,600 MPa."
This is the first time he has directly 'predicted' the outcome.
Others immediately looked over.
People in the laboratory were immediately full of expectations, and they still trusted Peng Hui's judgment.
Several expert judges also discussed, "It would be great if it could exceed 1,600."
"Yue Zhiquan seems to be very optimistic about it. When he saw the finished product, he clamored to go in for testing."
"I've seen it too, and it feels very average. It's not as good as the last product."
"It's unlikely." Li Jiping whispered to Cao Dongming, "I haven't seen the finished product, but this kind of research, even if it increases by ten megapascals, it will be a great progress."
"1570 MPa, 1580 MPa, I believe, no matter how high it is..."
Li Jiping said and shook his head.
Cao Dongming didn't speak, because he felt it was not easy to make a judgment.
At this time, the door of the testing room opened, and Yue Zhiquan walked out with a calm expression on his face. Peng Hui immediately asked in a high voice, "Professor Yue, how are you?"
"How many?"
"Is there any result?" Several others asked.
Yue Zhiquan took a deep breath, and seemed to be holding back a number before telling him, "1790."
"What?"
Others thought they heard wrongly.
"1790."
Yue Zhiquan said it again, and then became excited, "I mean, 1790! Do you believe it? I just saw the data and I didn't believe it."
His voice was higher than Peng Hui's, with an incredulous smile on his face, "1790! I've never seen this value on titanium alloy, and there's no information or news on it."
"Peng Hui!"
He called Peng Hui and sighed, "This project of yours...is really a big success."
Peng Hui was stunned for a long time. He raised his fist and hit the wall hard as if to vent his anger. He cursed angrily with curse words, "Oh no, it really hurts! It hurts! 1790, 1790!"
"Hahaha~~~~1790!"
Instantaneous.
Others also started discussing excitedly, and the whole laboratory was suddenly filled with excitement.
