"We can sign an agreement with you now that we will give you a state-of-the-art thermal spray machine." Qin Hai said solemnly, and at the same time handed a look to Lutenberg, and the meaning of the look translated into Chinese is: You know.

Rutenberg has a high IQ, and his EQ is higher than his IQ, and as soon as he heard Qin Hai's words, he understood what he meant, and he said: "If this is the case, I can decide on behalf of the board of directors now to confer the title of honorary professor for life on Professor Li and Professor Yue, as for Mr. Qin, you ...... If you don't like it, we can award you an honorary doctorate. ”

"This is exempt...... Qin Hai hurriedly waved his hand, he is just a technical school student, if he gets an honorary doctorate abroad, he doesn't know whether he will recognize it in China, he firmly grasped the topic, and said to Rutenberg: "Mr. Rutenberg, you have seen, we are about to hold an academic report, I plan to ask Professor Li and Professor Yue to introduce the development of thermal spraying technology to manufacturers around the world." If the matter of honorary professors can be announced now, I think it will have a good impact on the two professors and your university. ”

"You're absolutely right, I'm going to do it right away." Rutenberg nodded in agreement.

In fact, about conferring honorary professorships for life on Li Linguang and Yue Kun, Rutenberg has already privately communicated with the members of the board of directors. The value of the thermal spraying process is well understood by those in the circle, and Li Linguang and Yue Kun, as experts in making breakthroughs in this technology, are fully qualified to receive this honor from the University of São Paulo. Ruttenberg covered this matter and refused to say it, the purpose was to get a thermal spraying machine from Li Linguang and them, and now that Qin Hai agreed to give away the machine, Ruttenberg of course had to repay the favor and quickly announce the awarding of the title.

When the time for the report to be drawn up came, Cui Hongchun, Qin Hai and others slowly walked to the podium and sat down on the guest seats. The audience gradually fell silent. On behalf of the organizing committee, Brownlee announced the start of the report meeting, Qin Hai sat on the stage and made a gesture to Qin Shan in the audience, Qin Shan willingly pressed on the slide projector next to him, and a beam of light was projected on the large screen on the side of the podium, and the theme of the speech was clearly displayed:

innovation and application of thermal spraying process;

Speaker: Li Linguang. Kun Yue (Anhe Institute of Technology, China).

Seeing the content on the slide, everyone in the audience began to whisper, and the most discussed was the identity of the speaker:

"Anhe Institute of Technology, what kind of college is this?"

"Li Linguang, Yue Kun...... Have you read their papers? ”

"How can two people who are not famous report that they are the original creators of the technology?"

“……”

In the midst of the discussion, Qin Hai whispered a few words to Cui Hongchun, and Cui Hongchun stood up with a smile. He walked up to the podium and said, "Good morning, ladies and gentlemen. I am Cui Hongchun, Vice Minister of Agriculture of China, and my colleagues and I are very welcome to come and listen to the technical report made by the Chinese Agricultural Machinery Delegation. Since this report is an academic presentation, I would like to invite Professor Ruthenberg, a member of the Board of Trustees of the University of São Paulo and a well-known scholar, to be the moderator of the presentation. ”

Hearing Ruitenberg's name, there was a small commotion on the field. Those who were interested in coming to listen to this presentation were people who worked with materials. Or a technician from an enterprise, or a scholar from a university. They had never heard of the names of Li Linguang and Yue Kun, but they were no strangers to Rutenberg.

In the applause of everyone, Ruttemberg walked to the speaker with a smile, shook hands with Cui Hongchun, who was giving up his position, and then watched Cui Hongchun walk back to his place and sit down, and then said to the audience:

"Everyone. It is a great honour for me to be invited by Mr. Minister to be the moderator of this briefing. I think you are all very aware of the development of spraying technology, but as of yesterday. Spraying technology is still in the field of high-end equipment manufacturing, and cannot be applied to the majority of ordinary equipment manufacturing. However, this regret has now been solved by my China and Mr. Lin Guang and Mr. Yue Kun, who have used the thermal spraying machinery they designed to process the farm tools, which I believe you have seen.

Now, I would like to invite Mr. Li Linguang, a tenured honorary professor of the University of São Paulo and a professor of Anhe Institute of Technology in China, to introduce to us how such a miraculous metal surface treatment process is proposed and how to apply it. ”

The applause on the "......" field rang out like a rising tide, from weak to strong, and quickly turned into thunder.

In the midst of this applause, Li Linguang stood up with a smile and walked towards Rutenberg. Qin Hai noticed that Li Linguang's steps were a little stiff, and it seemed that the old gentleman was still a little nervous. Don't look at the countless big lectures he has given in school in the past, speaking on such an international podium is still the first time for him to get married.

"It is a great honor to be able to report to you some of the achievements that Professor Yue Kun and I have made in thermal spraying technology...... "Li Linguang began his speech, he is not fluent in English, but the content of the lecture is very professional.

Qin Shan and Ning Mo, who were arranged by Qin Hai to be in charge of putting the slides, pricked up their ears and listened to what Li Linguang said with a high degree of nervousness, making sure that they switched the slides at the right time to be consistent with Li Linguang's narration. They had studied the slides more than a dozen times before, just to make sure they didn't make mistakes.

"This Qin Hai, it's really hateful to hand over such a difficult thing to the two of us." Tranquility nagged at Qin Shan while inserting the slides.

"My brother is on stage, so he can't come down and help us put out the slideshow." Qin Shan defended her brother.

"He doesn't have anything to do, what are you doing sitting on the stage?" Tranquility Road.

Qin Shan said: "It's not that you don't know that these techniques that Professor Li talked about were first proposed by my brother. He sat on the stage, probably because he was afraid that Professor Li would make a mistake. ”

"Your brother is too capable, isn't he? Professor Li is not as capable as him, and I don't know how long his brain is. Tranquility looked at Qin Hai, who was sitting on the stage with a breezy face, and her heart moved inexplicably.

The two little girls only knew that there were many foreigners who came to this report, and it looked very grand, but they didn't know much about how amazing the technology introduced by Li Linguang was. The other people sitting in the audience are different, from the beginning of Li Linguang's introduction, everyone realized that it was worth it to come all the way, the content of Li Linguang's speech, and some of the problems they had thought about vaguely had various connections, they saw the light of solving problems from these stories, and they couldn't help but have a sense of sudden enlightenment in front of them.

"In thermal spraying, there is a heat exchange between the hot air or flame stream and the sprayed particles being carried in two ways. The first way, convection. We can take a look at the formula for heat transfer in convection...... This symbol represents the Nusselt number, which is the thermal conductivity of the flame flow......" Li Linguang pointed to the formula on the big screen, and gradually found the chic feeling when he was lecturing.

Everyone in the audience took notebooks and smacked down formulas and essentials one by one, as if they were listening to a lecture in a university classroom. Many scholars, who were still a little contemptuous, also became stern one by one. As the saying goes, if an expert stretches out his hand, he will know if there is one, and these contents of Li Linguang's lectures can be understood by professionals as soon as they hear it, and at the same time, they also have a sense of reverence for this unremarkable Chinese professor on the stage.

"Mr. Li, may I ask, do you own the patent for the supersonic nozzle you just mentioned?" Someone couldn't help but raise their hand and ask. They can hear that this technology is one of the key technologies that makes the thermal spraying process commonplace, and if the Chinese have the expertise of this technology, other manufacturers who want to engage in thermal spraying must pay patent fees to the Chinese. On the contrary, if the Chinese do not have its patent, then everyone must quickly go back and organize manual research and grab this patent in front of their peers.

"Well, we haven't got a patent yet." Li Linguang said leisurely.

As soon as these words came out, more than a dozen people stood up at the venue, and they were about to go out, and this was the person who was going to grab the patent. Before they could take a step, Li Linguang's last sentence had already been said: "However, we are already applying for a patent, and this technology is in the patent protection period......"

At the same time, Qin Shan and Ning Jing changed a slide in time, and the big screen displayed the name, application time, number, and other information of the patent being applied. Seeing this information, those who stood up all sat down, and there was no point in going back now.

Cui Hongchun, who was sitting on the stage, saw this scene off the stage, and his heart fluttered several times. He didn't expect foreigners to be so sensitive to patents and so eager to grab them. He turned his head and asked Qin Hai beside him in a low voice, "Xiao Qin, have you applied for patents for these technologies?" If you haven't had time to apply yet, don't let Professor Li tell me about it. ”

Qin Hai smiled and said: "Minister Cui, don't worry, we have always paid great attention to the matter of patents, and all the technologies we have researched have applied for patent protection in the first time, and the cost we have paid for this is not small." Applying for a patent abroad requires paying foreign currency, and you know how difficult it is to get some foreign currency now. ”

"No matter how hard it is, you have to do it, and no matter how big the cost is, it's worth it." Cui Hongchun said, "We didn't pay attention to patents in the past, and in the past two years, there have been a lot of foreign patent infringement lawsuits, which have made many of our factories very wolfy." The thermal spraying machine you are building is very advanced in technology and must be protected by patents. What about foreign exchange...... It's good that you can figure it out for yourself.
