Hearing Professor Liu's words, Lin Su felt a little crying and laughing at this time.

She only realized now, it turned out that Professor Liu was sometimes skeptical about whether she was the author of this manual.

Of course, even if it is doubted by Professor Liu. In the heart of the machinery factory, there is no sense of annoyance. After all, it can be seen from Professor Liu's attitude. Professor Liu attaches great importance to talents. In terms of knowledge, he is also very serious.

In addition, Professor Liu is now famous in the province and even in the country in terms of machinery and numerical control. Lin Su believes that as long as he can win Professor Liu's trust and support. Even if Wang Zhicheng and the others really took out the manual that they stole from their hands, Professor Liu would definitely not buy it.

So at this time, Lin Su sat up straight and explained to Professor Liu very solemnly: "Professor Liu, I understand, because of my age and my study experience, you have doubts about whether I can write this manual.

However, I can assure you that every word on this manual is written by me. The picture inside is also drawn by myself. Everyone in the office of the production hall on our machines can testify. This manual was written out by me in the office, page by page, and everyone saw it.

Of course, you saw for yourself that I had written the manual, because someone had stolen it. So, I had to rewrite a new one. The one I'm showing you now is the second one I've written. The contents are almost identical to the first one, with only minor changes.

As for what you said, I did not study it systematically. I'll admit that I really didn't systematically learn from the teacher about CNC and mechanics.

However, when I used to be in the country. There is an insider in our village who used to go to school at the Technical University of H City. At that time, I would often go over and read books with them. I've seen all the books he brought with me about numerical control.

Moreover, his personality is particularly good. Seeing that I am interested in this aspect of the content, when I have time, he often teaches me something about this aspect. On this point, those who know in our village can testify to me.

Moreover, after I went to study in our county, I often paid attention to this aspect of the content. In my house, I still have a few books on numerical control that I found in the county. ”

What Lin Su said was seven points true and three points false, not to mention Professor Liu and Professor Lu, it was impossible to really investigate. Even if he did investigate, he wouldn't have found any loopholes.

Lin Su did have contact with the person who knew about it, and those people in the village could indeed testify for Lin Su. As for whether he taught Lin Su this knowledge, with the death of the person who knew it, it can be regarded as a death without proof.

In Lin Su's house, there are indeed some books on numerical control. The reason why Lin Su collected these books was simply because Lin Su wanted to have a clearer understanding of the degree of development in numerical control in this era. Of course, it is also to hide people's eyes.

After hearing Lin Su's words, although Professor Liu still had some doubts in his heart about whether Lin Su could write this manual. But her attitude is much better.

After all, there are still geniuses in this world. The reason why he had a bad attitude towards Lin Su before was also in the spirit of truth-seeking, and he didn't want talented people to be buried. Now it is possible that Lin Su is the author of this manual, and Professor Liu will not suspect Lin Su until he finds definite evidence that Lin Su is lying.

"However, in this manual of yours, there is a lot of knowledge about the internal structure of CNC machine tools. If it weren't for the old workers who have been dealing with CNC machine tools for more than ten years, they would not have understood these machines so clearly.

I would like to ask, you said that you just came to work in the machine factory last year. For the entity of the CNC machine tool, the understanding is not particularly clear. How did you do it, draw the parts in the CNC machine so clearly?"

"I really didn't know much about the internal structure of CNC machine tools. However, I used to be with the brother who knew about it and watched him draw the inner workings of some CNC machines. Because I am more interested in this knowledge, I also memorize these contents by heart.

Although I have never touched CNC machines before. However, I have also seen some drawings of the internal structure of CNC machine tools. Moreover, when I first arrived at our county machinery factory. In our county machinery factory, there are two CNC machine tools that have problems. At that time, the experts in the province did not have time to go to our county to repair it. Because I know some basic knowledge, I rolled up my sleeves.

It was also through that time that I was able to connect some of the knowledge I had seen in my mind with the actual objects. It was also from that time that I thought about writing a manual to let more people know about CNC machine tools and not encounter such a thing again. ”

Professor Liu, who had some doubts in his heart before, began to believe Lin Su's words at this time. He raised his head and looked at Director Zhang.

Seeing Professor Liu's gaze, Director Zhang nodded very affirmatively and said, "That's true, last year, I also came to our school to find experts and went to our machinery factory to repair CNC machine tools." It's just that during that time, the big guys went out to study. The remaining two people had another accident. We really had no choice, so we asked Lin Su to help fix it. However, she repaired it very well. Those two CNC machine tools have been working until now. ”

Professor Lu, who had been sitting next to him and did not speak, also believed Lin Su's words at this time. He picked up Director Zhang, and flipped through the stack of manuscripts that had just been handed to him.

Then, from time to time, he began to ask Lin Su some questions. Lin Su knew that Professor Lu was taking the school examination. But for this test, Lin Su did not panic at all.

After all, Lin Su had worked in the laboratory for so many years. Her IQ is not particularly high, but it is above average. What's more, this manual was indeed written by Lin Su. The knowledge written on it can be said that Lin Su is familiar with it by heart.

Therefore, as time went by, the attitude of Professor Liu and Professor Lu towards Lin Su became better and better.
