It can be seen that Professor Zhong cares very much about Zhang Yi's technical solution, and has also engaged in a lot of battles in order to verify this plan, which makes Zhang Yi also have a feeling of being taken seriously.

"Professor Zhong, there is not much problem in the experimental scheme, some technical parameters still need to be continuously optimized, and then the experiment is done systematically, and the index will rise a lot." Zhang Yi said softly.

Professor Zhong also nodded after listening, but he also knew that a project of such difficulty would never be so simple, and there were many ways to do it.

It would be a mistake to think that if you make this breakthrough now, you will be able to complete the project just around the corner.

Sometimes even if you know the technical method, you may not be able to make the result, just like a lot of things bought in the supermarket, the packaging bag will tell you how this thing is made, but you think that you can easily make it according to the method it says, it is too naïve, how do other manufacturers do business.

The national standard requires that the molybdenum content in high-quality tungsten metal shall not exceed 0.002%, even if Professor Zhong has repeatedly made breakthroughs in the project, but if this indicator is not reached, the project will still fail.

It seems that the project is still very early to succeed, and there are still many details that need Zhang Yi's guidance, if there is no Zhang Yi's full help, I am afraid it will be difficult to achieve that devil indicator.

"Zhang Yi, this project still needs a lot of help from you." Professor Zhong looked at Zhang Yi with a look of hope and said, I didn't expect that an undergraduate student recruited into the laboratory would be so powerful, and if you train it well, your future achievements will be absolutely limitless.

"It's okay, Professor Zhong just tells you to." Zhang Yi said with a smile.

Although the graduate students present did not understand why Professor Zhong kept asking Zhang Yi for advice like a student, they had obviously seen that this student was not an ordinary person.

"Okay, I'll take you somewhere." After thinking for a moment, Professor Zhong looked at Zhang Yi and said, his eyes revealing a hint of determination.

Then Professor Zhong announced the adjournment of the meeting, put all the materials on the table into his briefcase, and beckoned Zhang Yi out of the office.

......

After leaving the office, Zhang Yi got into Professor Zhong's car.

A black Ford Focus.

There are not many university teachers who can afford to buy a car in 98, but Professor Zhong still has the financial ability to buy a car for himself.

After the car left Jiangda, it drove for more than half an hour and stopped in front of a large courtyard.

The yard is located in the downtown area, looking up from the gate, the trees in the yard are towering, the grass and trees are quiet, but the guards are strict, it can be said that there are three steps and one sentry, five steps and one post, and the scene of traffic on the street outside forms a huge contrast.

When the car approached the gate, several large characters of the Institute of Physics of the Chinese Academy of Sciences stood in front of me.

Zhang Yi didn't know why Professor Zhong brought him here, but Professor Zhong didn't say anything, and he couldn't ask.

After registering at the door, Professor Zhong took Zhang Yi to a small two-story building in the institute, the shaded side of the building was completely covered with vines, and only a few windows could be seen.

Professor Zhong walked straight to the second floor and stopped in front of an office with the words "Director's Office" written on the nameplate, the door ajar, and Professor Zhong knocked lightly a few times.

"Come in." A middle-aged man's voice came from inside the office.

Professor Zhong took Zhang Yi and pushed the door in.

"Professor Zhong, what kind of wind blew your great professor here?" The middle-aged man sitting behind the desk said in surprise, obviously he didn't expect Professor Zhong to come over at this time, and hurriedly beckoned Professor Zhong and Zhang Yi to sit down.

The middle-aged man was slightly fat, looking to be in his 40s, but his hair was a little sparse.

"Director Wu, I want to communicate with you about the progress of the tungsten and molybdenum separation project." Professor Zhong sat down on the sofa in his office and beckoned Zhang Yi to sit next to him.

Director Wu said with a smile: "The project is really important, and our institute is also tackling key problems, so we can do the next step of research before we can wait for your results to come out." ”

Hearing Director Wu say this, Professor Zhong shook his head with a solemn expression and said, "I'm sorry Director Wu, I can't do anything about this tungsten and molybdenum separation project. ”

"This ......" Director Wu's smile instantly froze on his face, and it took a while to react, and he frowned and said, "Professor Zhong is joking with me." ”

"No, absolutely no joke, I organized my graduate students before, and I did experiments for more than a month, and there was no progress at all." Professor Zhong's expression was calm, as if he was talking about something that had nothing to do with him.

"Then ......" Director Wu's brows furrowed even deeper, and he said a little nervously: "Can we still sign the contract for this project?" ”

Hearing what Professor Zhong said, Director Wu was really nervous, the institute is carrying out a major scientific and technological research project, which requires the use of high-quality tungsten metal with very high purity.

However, the purity of tungsten metal that can be bought on the market is very low, mixed with other metal elements, such tungsten metal can be used as an extensive type of industry, but they want to do scientific research projects with very high precision requirements, and they must have tungsten metal of extremely high purity.

In desperation, the institute set up a project team and entrusted scientific research institutions or university research teams to carry out technology development.

It just so happened that Su Xue, the younger sister of Director Wu when he was a graduate student, was a teacher at Jiang University, and under Su Xue's recommendation, the institute also found Professor Zhong and wanted to establish a cooperative relationship with him.

If Professor Zhong can't make it, then there will be no source of tungsten metal needed later, and the follow-up scientific research will not be able to continue.

"The plan we negotiated before can't be implemented, and the contract can't be signed." Professor Zhong shook his head and said.

The contract for this tungsten-molybdenum separation project has not yet been finalized, and Professor Zhong was only entrusted to do experiments before, and if Professor Zhong's experimental results are possible, a formal contract will be signed directly.

Director Wu didn't seem to have recovered from the shock, and said anxiously: "Does Senior Sister Su know about this?" ”

"I discussed it with Professor Su, but she seemed to think that it was my responsibility, and she didn't want to pay attention to it, so I asked me to do it." Professor Zhong said helplessly.

"This ......" Director Wu was a little depressed, but also a little annoyed, he had talked about it well before, but now he said that he would not do it, he was responsible.

Seeing that Director Wu was about to go crazy, Professor Zhong said lightly: "Our previous plan is not feasible, but we have achieved success in the laboratory, and tungsten and molybdenum separation can be made. ”

Hearing Professor Zhong's words, Director Wu was stunned, this style of painting has also turned too fast!

"Haha, Professor Zhong, you are joking, I can't stand your scare, but don't be scared out of heart disease." Director Wu was also relieved after the initial shock, and in his opinion, it was Professor Zhong who was scaring him just now.

I was scared just now, but now I let you see hope again, how can ordinary people bear this one.

"It's really not a joke." Professor Zhong said with a serious expression: "The technical solution we agreed on before was not feasible at all, so the contract could not be signed. ”

After speaking, Professor Zhong pointed to Zhang Yi who was sitting beside him.
