There is no such thing as overtime for researchers in universities.

When the research in hand is about to make progress, everyone will consciously work overtime, Peng Hui ordered, the metal laboratory up and down all the operation, some called up the monitoring research record Wang Hao said the content, some to prepare the materials for the new experiment, check the operation of the equipment, and some began to do relevant analysis, records and so on.

At the same time.

After Wang Hao left the metal laboratory, he talked to Ruan Hailong on the phone, and the two went to the restaurant with a smile when they met.

They ate at a restaurant off campus.

Ruan Hailong ordered a few hard dishes, and especially asked for two bottles of beer, and talked about it while eating and drinking, and the topic was still on Wang Hao.

There are too many topics on Wang Hao, he has relied on his personal achievements to continuously appear in the news, and recently it is related to the Donggang University incident, and Ruan Hailong also congratulated him on being able to wash away the 'stain'.

Although the so-called 'stain' is nothing to Wang Hao, and after completing many international achievements, it has no impact on him, but no one wants to talk about it in the future, and they will talk about being dismissed from Donggang University because of experimental mistakes.

It was a failure.

But so far, because Wang Hao has completed a lot of achievements, some of which are world-class achievements, and is even considered to be a future Fields winner, the losing side has become Donggang University.

After the results of the investigation into the Donggang University incident came out, they felt that they had failed even more when they talked about this matter, because they had made a wrong judgment and dismissed an international-level mathematical genius, which was equivalent to sending it to Xihai University.

Ruan Hailong said with a smile, "When this matter was on the news, I was still posting on Weibo, but unfortunately there were not a few fans, only a few replies, and they were all sent by colleagues." ”

"At that time, I said that something was wrong in this matter, because I knew that you could not have made a miscalculation in the main experimental work."

To say that a top mathematician can make simple calculation mistakes is simply an insult to a mathematician.

Of course, everyone gets it wrong.

However, for example, the data calculation of an important experiment must not only be calculated once, but will be carefully checked and checked, and it may be checked several times in different ways.

In such a serious state, there are many miscalculations, and it is almost impossible to happen.

Then they talked about the study of Mersenne primes.

Ruan Hailong suggested that Wang Hao go to the Center for Mathematical Sciences of Shuimu University to present the results, "If the results are presented at an international conference, they must be presented in English and very formally." ”

"If you go to Mizuki University, it's different, because your thesis has already been submitted, and you don't need to do a report in English, just do a description in Chinese."

"It's also relatively free to go to the Mathematical Sciences Center of Mizuki University, and it also has certain benefits for developing contacts."

He talked about another topic, "In China, the mathematics circle is big and small, and there are only six universities that have the main influence. ”

"What's the point of this?" Wang Hao asked with interest.

"It's simple, academicians distributed." Ruan Hailong said, "There are only so many academicians of mathematics in the Academy of Sciences, most of them are concentrated in six universities, and there are few others scattered. ”

"If you think about it, if it is to select academicians, academicians from their own institutions will definitely be more willing to recommend professors from their own institutions."

Wang Hao nodded understandingly.

As long as you are a human being, you will have selfishness, and it is the same if you are an old academician.

If two professors of similar level participate in the academician selection together, the person with the right to vote will undoubtedly vote for the one close to him.

Universities with a concentration of academicians in a single field form a circle, and the boundaries of the circle are very blurred, but they do exist.

Ruan Hailong continued, "The largest number of academicians are Capital University and Donggang University, and the two universities are also the most competitive in mathematics. ”

"If you have been at Donggang University, it is definitely the best in this school to give a report, but now that you are at Xihai University, you still have a bit of a contradiction with Donggang University, and with the results, it is a good choice to go to the Mathematical Science Center of Shuimu University."

"It wouldn't hurt to get to know some of the top people in math, right?"

Wang Hao nodded knowingly.

Although he can be said to be a person without a 'faction', he is not in the so-called 'six universities with the most academicians', and he is not interested in developing any contacts, and similar things are just listening, but it is indeed relatively easy to go to Mizuki University to make a report, and you can also make a report in Chinese.

Now the results of Mersenne primes can be said to have entered the state of application, and the results have been recognized by the world, and it does not matter whether the report is done or not, the main thing is to let others understand the research better.

It is a good choice to go to Mizuki University to give a report in Chinese.

Wang Hao and Ruan Hailong drank beer and chatted until nine o'clock in the evening, and then went back to the hotel after checking the time.

The next morning, he went to enter the metal lab again, prepared to take a turn, said hello and left.

When he entered the laboratory, he found that 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.

At this time, Wang Hao knew that they were preparing to conduct a new experiment.

"That's too fast, isn't it?" Wang Hao felt a little incomprehensible, "Didn't you say that the funds were not enough?" It costs a lot of money to do experiments......"

"Lack of funds is also relative, there are new ideas, and experiments must be done!" Wan Yiming said as a matter of course.

Wang Hao entered the conference room, and Peng Hui immediately greeted him warmly, asked him to sit on his left hand, and talked about the content of today's experiment, and repeatedly asked his opinion.

Wang Hao said with a little confusion, "I am still going to fly back at noon, if it is to do an experiment, I will stay for another day, but I just look at the experiment, I really don't know about alloy manufacturing, I know very little." ”

"Professor Wang Hao, you are too modest, if you don't understand, what are we?"

"What you said yesterday really gave us a lot of gain."

“……”

Wang Hao felt that the world had changed.

He did say a lot of things yesterday, but he just said something based on his own understanding, and he only said a little suggestion, and even if it was all correct, it didn't feel like it had a big impact.

This is what he does not know about the research of alloy materials.

In the study of alloy materials, every bit of progress is a big progress, unlike the content of mathematics, there must be many ideas to solve a problem, alloy is a real manufacturing problem, and every small improvement can be said to be a huge progress.

Because of this, Peng Hui was in a hurry to ask for the next experiment.

The meeting in the laboratory is mainly to establish the overall process of experimental manufacturing and make sure that all preparations have been completed.

Halfway through, Wang Hao also said a few words.

Wang Hao felt that there was really nothing to say, so he said a few words according to yesterday's words, and then had a little inspiration, and 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 little slow, right? You can choose a faster cooling and quenching method, and the faster you go, the better the results. ”

After Wang Hao put forward his opinions again, others began to discuss them, and finally modified the quenching method.

After combing through the details of the whole process, Peng Hui announced the start of the experiment on the spot, without considering the issue of time at all.

At ten o'clock in the morning, the titanium alloy manufacturing experiment officially began.

Wang Hao stood in the operation room wearing a work uniform, watching the process one by one from a safe distance, and knew that the whole process was to mix all kinds of powders together first, and then carry out uniform stirring, cooling of the mixed solution, etc.

The process is very simple, but in fact, there are more than 10 kinds of processes alone, and various processes are carried out in the middle, and some very specialized machines are used.

Mixing and quenching is the most time-consuming, because the addition of a melting and quenching process takes longer.

It was not until three o'clock in the afternoon that the final step was completed, and then the finished product began to wait for the natural cooling of the finished alloy.

Because they are not making metal parts, they are making a new alloy, and in the end they do not need to be cooled and quenched to improve the hardness of the metal surface.

That's not necessary.

Four o'clock.

After the new alloy has been manufactured, the cutting inspection begins, and the main inspection has two aspects, one is to test the tensile strength, and the other is the yield strength.

The tensile strength and yield strength of titanium alloy at room temperature are very important indicators.

A large group of people stayed in the laboratory, waiting for the test results, and Peng Hui kept walking around, as if he wanted to enter the equipment room and do the test in person.

Finally, a shout came from the equipment room, and a staff member came out and shouted with surprise, "Yield strength, 1380 megapascals!" ”

"It's confirmed, it's this number!"

"We tested twice in a row, once at 1,373 megapascals and once at 1,388 megapascals, both of which exceeded 1,370, and the average was around 1,380!"

"Hula!"

After hearing the value of strength, the entire corridor was boiling, and Peng Hui said with surprise on his face, "Really? Test it again and see! Test again! ”

He couldn't believe it and wanted to verify it again.

Soon, another value came out.

"Tensile strength, 1410 megapascals!" This value caused another round of cries in the laboratory.

Wang Hao still has some understanding of the performance indicators of titanium alloys, and knows that the tensile strength of titanium alloys at room temperature is generally below 1400 megapascals and up to more than 1700 megapascals.

Because he understands the numbers, he doesn't understand the excitement of the lab.

It's probably an improvement, but it's very small.

Shi Guifang found Wang Hao's incomprehension and explained, "Compared with the finished product manufactured last time, the tensile strength and yield strength are more than 100 higher, which has reached the expected goal of the research, and the results can be announced and submitted." ”

"Yes, the goal has been achieved!"

Peng Hui was very excited, and his face was red as he spoke, "We have not only developed a new type of titanium alloy with improved strength, but also simplified the manufacturing method, which is a great result!" ”

"But ......"

Wang Hao tugged at the corners of his mouth and said, "I feel that the research has just begun, right?" I haven't done my data analysis yet. ”

"If the data analysis is done and there are results, it will definitely be able to continue to improve, and this kind of research will have to be qualitatively improved, and there are a few more performance parameters, what is the use?"

"Forehead ......"

Peng Hui felt that the results seemed to be despised, he couldn't keep up with his thinking, and reacted and hesitated, "Or, wait?" Not to be announced yet. ”

Shi Guifang reminded, "It should be able to be announced, right?" If it is announced, maybe it will be possible to apply for new funding? ”

"That's right!"

Peng Hui thought about it and nodded very hard, "That's it, announce it, and then take a look, wait and ......."
