Chapter 106 Is this complete? Research has just begun!
There is no such thing as overtime for scientific researchers in universities.
When the research at hand is about to make progress, everyone will consciously work overtime. Peng Hui gives an order, and the metal laboratory is all in operation. Some call out monitoring research to record what Wang Hao said, and some prepare new information.
Experimental materials, checking the operation of equipment, and some started to do relevant analysis, records, etc.
at the same time.
After Wang Hao left the metal laboratory, he talked on the phone with Ruan Hailong. When they met, they chatted and went to the restaurant.
They ate at a restaurant outside the school.
Ruan Hailong ordered a few hard dishes, and also ordered two bottles of beer. While eating and drinking, they started talking, and the topic was still about Wang Hao.
There are so many topics surrounding Wang Hao. He has been in the news continuously due to his personal achievements. Recently, it has been related to the Donggang University incident. Ruan Hailong also congratulated him for being able to remove his "stain".
Although the so-called "stain" is nothing to Wang Hao, and after completing many international achievements, it no longer affects him, but no one wants to talk about being dismissed from Donggang University due to experimental errors in the future.
That was a very unsuccessful experience.
But so far, because Wang Hao has accomplished many achievements, some of which are world-class, and is even considered a future Fields winner, the losing side has become Donggang University.
After the investigation results of the Donggang University incident came out, when talking about this matter, I felt that they had failed even more, because they made a wrong judgment and dismissed an international-level mathematics genius, which was equivalent to giving it to Xihai University.
Ruan Hailong said with a smile, "When this matter was in the news, I was still posting on Weibo, but unfortunately I didn't have many fans and only a few replies, all from my colleagues."
"I said at that time that there was something wrong with this matter, because I knew that it was impossible for you to make a calculation error like that in major experimental work."
To say that a top mathematician can make simple calculation errors is simply an insult to mathematicians.
Of course, everyone makes mistakes.
But for example, the data calculation for important experiments will definitely not only be calculated once, but will be carefully checked and calculated, and may be checked several times using different methods.
It is almost impossible for many calculation errors to occur in such a serious state.
Then they talked about the study of Mersenne primes.
Ruan Hailong suggested that Wang Hao go to the Mathematical Science Center of Shuimu University to publish the results. "If the results are to be published at an international conference, the report must be in English and the report must be very formal."
"It's different if you go to Shuimu University. Because your thesis has been submitted, you don't need to make a report in English. You can just make an explanation in Chinese."
"It's relatively free to go to the Mathematical Science Center of Shuimu University, and it's also good for developing contacts."
He talked about another topic, "In China, the mathematics circle is big or small, and there are only six universities that are mainly influential."
"What's the explanation for this?" Wang Hao asked with interest.
"It's very simple, the distribution of academicians." Ruan Hailong said, "There are only so many academicians in mathematics at the Academy of Sciences. Most of the academicians are concentrated in six universities, and there are very few others scattered around."
"Think about it, if it's the selection of academicians, academicians from their own schools would definitely be more willing to recommend professors from their own schools."
Wang Hao nodded in understanding.
As long as you are a human being, you will have selfish motives, and it will be the same if you are an old academician.
If two professors with similar levels participate in the academician selection together, those who have the right to vote will undoubtedly vote for the one who is close to them.
Universities with a concentration of academicians in a single field form a circle. The boundaries of the circle are blurred, but they do exist.
Ruan Hailong continued, "Capital University and Donggang University have the largest number of academicians. The competition in mathematics between these two universities is also the most intense."
"If you had been at Donggang University, your report would definitely be the best in this school. But now that you are at Xihai University, you still have some conflicts with Donggang University. If you have achieved results, going to the Mathematical Science Center of Shuimu University is a good choice."
"It certainly doesn't hurt to get to know more top people in the field of mathematics, right?"
Wang Hao nodded understandingly.
Although he can be said to be a non-clique person, he is not among the so-called "six universities with the most academicians", and has no interest in developing any connections. He only listens to similar things, but going to Shuimu University to give a report is indeed
It's relatively easy, and you can also make reports in Chinese.
Now the results related to Mersenne prime numbers can be said to have entered the state of application. The results have been recognized by the world. It doesn't matter whether the report is done or not. The main purpose is to let others understand the research better.
Going to Shuimu University to give a Chinese report is a very good choice.
Wang Hao and Ruan Hailong drank beer and chatted until nine o'clock in the evening. They checked the time and returned to the hotel.
The next morning, he went to the metal laboratory again, prepared to walk around, said hello and left.
After entering the laboratory, he found something was wrong. Everyone was busy and seemed to be preparing seriously.
When Wan Yiming saw Wang Hao, he pulled him to the conference room.
Only then did Wang Hao know that they were preparing to conduct a new experiment.
"Isn't this too fast? I haven't finished my analysis yet?" Wang Hao felt a little confused. "Isn't it said that the funds are not enough? It takes a lot of money to conduct experiments..."
"Insufficient funds are relative. If you have new ideas, you must do experiments!" Wan Yiming said matter-of-factly.
When Wang Hao entered the conference room, Peng Hui immediately greeted him warmly and asked him to sit on his left. He also talked about the content of today's experiment and repeatedly asked for his opinions.
Wang Hao said with some confusion, "I am planning to fly back at noon. If it is to do experiments, I will stay for another day, but I just look at the experiments. I really don't understand alloy manufacturing. I know a lot."
few."
"Professor Wang Hao, you are too humble. If you don't understand, who are we?"
"What you said yesterday really helped us gain a lot."
"..."
Wang Hao felt that the world had changed.
He did say a lot yesterday, but he only said some content based on his own understanding and made some small suggestions. Even if they were all correct, I felt that the impact was not very big.
This is because he does not understand the research on alloy materials.
In the research of alloy materials, every bit of progress is a big progress. Unlike mathematics, which requires many ideas to solve a problem, alloys are a real manufacturing problem, and every small improvement can be said to be a huge progress.
Because of this, Peng Hui rushed to ask for the next experiment.
The meeting held in the laboratory is mainly to establish the overall process of experimental manufacturing and ensure that all preparations have been completed.
I also asked Wang Hao to say a few words in the middle.
Wang Hao felt that there really was nothing to say, so he just said a few words as he said yesterday, and then with a little inspiration, he continued to say a few words, "I think this quenching method can be changed."
"For the last quenching, you are going to use isothermal quenching, but the speed is a bit slow, right? You can choose a faster cooling quenching method. The faster the speed, the better the effect will be."
After Wang Hao put forward his opinion again, others began to discuss it, and finally modified the quenching method.
After sorting out the details of the entire process, Peng Hui announced the start of the experiment without considering the time issue at all.
At ten o'clock in the morning, the titanium alloy manufacturing experiment officially started.
Wang Hao stood in the operation room wearing work clothes, watching each process from a safe distance. The entire process was to first mix the various types of polished powders together, then stir them evenly, cool the mixed solution, etc.
The process sounds very simple. In fact, there are more than ten kinds of processes alone. Various treatments are performed during the process, and some very professional machines are also used.
Mixing, smelting, and then cooling and quenching are the most time-consuming. Because a melting and quenching process is added, it takes longer.
I waited until three o'clock in the afternoon to complete the last step and produce the finished product, and then began to wait for the natural cooling of the finished alloy.
Because they are not making metal parts, they are making a new alloy. In the end, there is no need for special cooling and quenching to increase the hardness of the metal surface.
That's not necessary.
Four o'clock.
After the new alloy has been manufactured, cutting testing begins. There are two main aspects of testing, one is testing the tensile strength and the other is the yield strength.
The normal temperature tensile strength and yield strength of titanium alloy are both very important indicators.
A large group of people stayed in the laboratory, waiting for the test results. Peng Hui kept walking around, as if he wanted to enter the equipment room and do the test himself.
Finally, a shout came from the equipment room, and a staff member came out and shouted in surprise, "Yield strength, 1380 MPa!"
"Sure, it's this value!"
"We tested twice in a row, one was 1373 MPa, the other was 1388 MPa, both exceeded 1370, and the average is around 1380!"
"Hoola!"
After hearing the strength value, the entire corridor was boiling. Peng Hui said with surprise, "Really? Test it again! Test it again!"
He was so surprised that he couldn't believe it and wanted to verify it again.
Soon, another value also came out.
"Tensile strength, 1410 MPa!" This value caused another round of shouts in the laboratory.
Wang Hao still has some understanding of the performance indicators of titanium alloys. He knows that the normal temperature tensile strength of titanium alloys is generally below 1,400 MPa, and can reach up to more than 1,700 MPa.
Just because he knew the numerical values, he did not understand the excitement of the laboratory.
Although there is probably an improvement, the amount of improvement is very small.
Shi Guifang noticed Wang Hao's incomprehension and explained, "The tensile strength and yield strength are more than 100 higher than the finished product produced last time. This has reached the expected goal of the research, and you can make an announcement and submit it."
It worked.”
"Yes, the goal has been achieved!"
Peng Hui was very excited, his face turned red as he spoke, "Not only have we developed a new type of titanium alloy with improved strength, but we have also simplified the manufacturing method. What a great achievement!"
"But……"
Wang Hao twitched his lips and said, "I feel like the research has just begun, right? My data analysis hasn't been done yet."
"If the data analysis is completed and the results are obtained, we can definitely continue to improve. This kind of research needs to be qualitatively improved. What's the use of adding more performance parameters?"
"Forehead……"
Peng Hui felt that the results seemed to be looked down upon. He was a little unable to keep up with his thinking, so he hesitated and said, "How about waiting a little longer? Don't announce it yet."
Shi Guifang reminded, "Should it be announced? If it is announced, maybe we can apply for new funds?"
"Right!"
Peng Hui thought about it and nodded vigorously, "That's it, announce it, then take a look, and wait..."
