The Red Era, the Opening University Speech

Chapter 150 National Exchange Conference!

"I call it excimer laser. This type of laser is a cold laser. Theoretically, it has no thermal effect, strong directionality, high wavelength purity, and high output power."

"If it can be developed, it should be able to meet the requirements of distributed projection lithography machines."

After hearing his thoughts, Huang Xinhua's eyes lit up slightly.

But he was also a little worried: "This is indeed a good idea, but it will take a lot of effort to make this kind of laser!"

The research on this kind of laser is not as simple as improving the traditional photolithography machine. It may require the production of a special equipment to achieve it.

"It will take a lot of effort, but if it can be achieved, our country's lithography technology will be 20 years ahead of the world!" Li Mu said with a smile.

The first application of excimer laser in lithography was the third generation of lithography machines in 1978.

The current level of lithography machines in the world is generally still at the first generation, and the second generation may not even have been proposed yet.

As long as Xia Guo can develop it, it will be able to achieve a cliff-like lead in technology!

Hearing this, Huang Xinhua immediately stopped hesitating and said, "Okay, then I will go and discuss with Director Wang to set up an excimer laser research and development team."

After saying that, he took Li Mu and hurried to Wang Shoujue's office.

……

After listening to this, Wang Shoujue was surprised and delighted, and said, "If it really takes 20 years, it will be worth it no matter how much investment is made."

"Well, I will report to the Chinese Academy of Sciences tomorrow and ask them to find a group of expert professors who study optics as soon as possible."

"Let you, Li Mu, take charge."

"This is inappropriate..." Li Mu subconsciously wanted to use the excuse that he was still in school, but halfway through he remembered that he was about to graduate.

As for writing a graduation thesis, this reason probably won't work.

Any of his inventions could fill several articles full of useful information.

So he changed his words and said, "I am working at the institute, and my rank is only the lowest assistant researcher. How can I lead research?"

"I think it would be more appropriate for Professor Huang to take this position."

There is nothing wrong with this statement, but it sounds strange to Wang Shoujue and Huang Xinhua.

Assistant researcher is not suitable, but was it suitable when I was a student?
Wang Shoujue thought for a moment and said, "Then let's do it the same way as before. You will be the deputy team leader and Professor Huang will be the team leader, but you will still be the core."

"Once the distributed projection lithography machine is successfully developed, Director Wu and I will report to you and raise your rank!"

……

The next day, the exam continued.

Subjects such as Marxism-Leninism and Mao Zedong Thought were not difficult for Li Mu. He could remember the page and line of the knowledge point by just glancing at the questions.

Even if there are some parts that require understanding and analysis, as long as you write with a firm heart, you will basically not lose too many points.

……

After finishing the exam neatly, Li Mu did not go back to the classroom. If he went there, he would just discuss his grades with his classmates without any gain or enlightenment.

After leaving school, I rode my bike to the Agricultural Research Institute.

The gatekeeper didn't recognize him, but after seeing the student ID in his hand, he went in to report with some doubt.

Not long after, Director Wei Guowei came out in a hurry.

When he saw Li Mu, his eyes were filled with joy.

"Why are you here? Come in and sit down. Come in and sit down. Xiao He, take out my box of Da Hong Pao and make some tea!" Wei Guowei took his hand enthusiastically, shouted to the secretary to make tea, and then took him into the office.

Seeing their director being so polite to a young man, many staff members in the Agricultural Research Institute showed curiosity on their faces.

After entering the office, Wei Guowei said, "You go ahead. Professor Mi and his colleagues are using the institute's laboratory for research. I'll call them over right away."

"Wait wait, Director Wei, I just wanted to take up a temporary position here in the future, so I came to get to know the place. Don't disturb Professor Mi and the others." Li Mu said, not knowing whether to laugh or cry.

Hearing this, Wei Guowei said, "How can you say it's disturbing? They are currently researching the cypermethrin you mentioned last time."

"If we hadn't heard that you were preparing for your final exams, we would have come to ask for your advice a long time ago."

After saying this, he went to call for help immediately, regardless of Li Mu's continued dissuasion.

Not long after, Mi Shenghua, Yuan Peiye and Du Mingwei, the three main members who developed cypermethrin, rushed to the office.

As soon as they came in, they said enthusiastically:
"Hahahaha, I've been looking forward to seeing you for so long that you're finally here!"

"You don't know, when Old Chen heard that you were going to take up a position at the Agricultural Research Institute, he was so happy that he couldn't stop smiling!"

"He even planned to arrange a teaching position for you at the Agricultural College, but unfortunately he was scolded back by Dean Guo!"

Several people have met Li Mu many times and are old acquaintances.

Although they are generally more than 20 years older than him, their relationship is just like that of ordinary friends.

"Then I must thank President Guo later, otherwise I will have to work seven jobs." Li Mu made a joke, making everyone laugh.

It's not like they haven't seen one person holding multiple positions before, but this is indeed the first time someone has spanned multiple fields and made amazing achievements in each field!
After a while of joking, everyone quickly got down to business.

Mi Shenghua spoke first:

“The idea of ​​cypermethrin that you mentioned last time, we went back and thought about it and explored it for a long time.”

"The raw materials for the synthesis have been preliminarily established, including cyano, benzyloxy, methyl 2-dichlorovinyl and 2-dimethylcyclopropanecarboxylate."

"The next step is to start the experiment, but we are still confused about the synthesis route."

After saying this, he and the others looked at Li Mu with anticipation.

The only way they could think of to synthesize the raw materials was the limit of what they could do.

It’s not impossible to continue the research though. As for the synthetic route, we can always find it by trying one by one.

But if you have ready-made ideas that can save a lot of time, why not do it?

Facing the questions from everyone, Li Mu hesitated for a moment before saying, "As for the synthetic route, I haven't personally experimented with it, so I can't guarantee that it will work."

"In theory, the production of cypermethrin requires three reactions and one reduction to complete the final synthesis."

"Bromination, acetalization, debromination, etherification, and acetal reduction."

"After completing the above steps, the obtained product is reacted with dichloropermethrin chloride and sodium cyanide aqueous solution in a catalyst and toluene solvent to obtain cypermethrin."

"Of course, this is just my preliminary inference. The specific situation still needs to be verified in experiments."

After he finished speaking, Mi Shenghua and the other two frowned and fell into long thought.

Li Mu did not disturb them and drank Wei Guowei's Dahongpao silently. It tasted really good.

"I think the theory is fine, we can give it a try in an experiment." After a long time, Mi Shenghua finally spoke.

Yuan Peiye and Du Mingwei also said, "Having a specific R&D framework is better than just trying to catch a mouse blindly. I agree with that."

"I've heard that you're good at theory, but I didn't expect you to have such profound attainments. You came up with ideas for something that you just proposed during the last summer harvest."

"We are not as good as you in this regard!"

The three of them agreed with the plan and praised Li Mu a lot.

Little did he know that he didn't even finish what he said last time.

Li Mu smiled and said, "The three professors are too modest. Agriculture is not a subject that can be done well just by talking about theory. The key is to look at specific experimental verification."

"I still have a lot to learn from you on this."

“In the future at the Agricultural Research Institute, I hope the professors will give me advice.”

Getting along well with colleagues in the same unit is also a science.

"Learn from each other, learn from each other." Mi Shenghua and the other two laughed. Afterwards, they chatted for a while and then hurried to verify the synthesis route.

……

After Wei Guowei sent the three people back, he saw that Li Mu had not left yet, so he knew that he had something to say.

After thinking for a while, he remembered that Li Mu had just taken several sips of tea, and said, "I still have a box of Da Hong Pao here. If you like it, take it and drink it."

"That's not what I meant." Li Mu shook his head and said, "I just want to ask you if there are any professors in crop cultivation at the Agricultural Research Institute. I would like to learn from them."

"Oh, why did you think of studying this? Haven't you been studying pesticides before?" Wei Guowei asked curiously.

Although pesticide science and crop cultivation are both disciplines under agronomy, there are still significant differences between them.

Li Mu explained: "After tetramethrin, even if cypermethrin is developed, the increase in crop yields will not be that obvious."

"But crop cultivation is different. If we can cultivate high-quality and high-yield crops, the total output will be greatly increased."

“And this increase is much higher than the upper limit for pesticides.”

After listening to his words, Wei Guowei nodded silently.

He didn't expect that after Li Mu achieved breakthrough results in pesticides, he would turn to studying crop cultivation.

After thinking for a while, he said, "If you want to study, you can actually go to the Agricultural College. Professor Chen is an authority on crop cultivation."

"If he knew you were interested in this, he would be very happy!"

"At the Agricultural Research Institute, you can also freely access the archives' past research materials. I will personally approve the note for you!"

Normally, an assistant researcher does not have this authority.

But Wei Guowei knew Li Mu's abilities, a genius who could achieve great success in the semiconductor field in less than a year. His talent was beyond their imagination.

So I am willing to give him this opportunity to learn.

Hearing this, Li Mu quickly said, "Then I would like to thank Director Wei first."

Leave the Agricultural Research Institute.

Li Mu held the Dahongpao he had brought with him, quickly stepped onto the bicycle at the door, and rode towards home.

He is not looking for trouble, he is looking for work for himself.

The most important purpose of studying crop cultivation is to have the opportunity to meet Mr. Yuan.

The historical status of hybrid rice is no less than that of the two bombs and one satellite.

From 1976, when large-scale promotion began nationwide, to 2013, China's grain production increased by a total of 8000 billion kilograms through hybrid rice and chemical fertilizers.

These grains played an extremely important role in solving the food demand problem of the Xia State.

Without it, the Xia Kingdom would have to buy food from abroad to feed such a large population, which would have been a bottleneck.

"There is still a long way to go!" Li Mu sighed.

Helping Mr. Yuan can certainly bring hybrid rice to the market earlier, but his goal is even more ambitious.

In later generations, there was a soybean war between the Xia Kingdom and Emperor M, and they were defeated miserably.

Because Emperor M manipulated soybean prices, Xia country's soybean farmers suffered heavy losses, which directly led to the loss of dominance in the domestic soybean market.

If it weren’t for the financial crisis and the withdrawal of foreign capital, it would be hard to say whether it could be brought back in the end.

……

While thinking, Li Mu returned to the gate of the slum.

Just as he parked the car, he suddenly heard a noisy sound coming from the yard.

When I went in, I saw experts from three provinces and one ministry of machine building, chatting with Grandma Li, Uncle Zhong, Aunt Zhang and others.

"Xiao Mu is back, come on, the two experts have been waiting for you for a long time." Uncle Zhong was the first to see Li Mu coming in, and he immediately shouted.

This shout immediately attracted the attention of the neighbors who were watching the fun.

Li Mu stepped forward and asked, "Expert Wen, Expert Qin, why are you here?"

"Why, you're not welcome?" the two experts said with a smile.

"Of course not. Come on, come home and sit down." Li Mu hurriedly invited the two to sit down at his home.

After he took the Da Hong Pao tea he had just brought from the Agricultural Research Institute and gave it to the two of them, he continued, "Is it about the top-blowing oxygen converter technology?"

"Yes." Expert Wen nodded decisively.

Expert Qin at the side said: "The three provinces and the Ministry of Machinery Industry have all sent us messages, asking us to bring back the top-blown oxygen converter technology as soon as possible."

"Although Director Ye of the Chemical Metallurgy Research Institute and Professor Zhang of the Beijing Institute of Technology are also familiar with this technology, we need your design ability more."

"The industrial strength of the three provinces has always been at the top level in China. Our leaders feel that a 300-ton top-blown oxygen converter is not enough. It would be best if we could get 400 tons."

After hearing what he said, Li Mu couldn't help but laugh.

He was silent for a moment, then said helplessly: "Two experts, I know that the three provinces have a good industrial foundation and the strongest technological accumulation."

"But now the 300-ton level is already the limit of current technology, and it is not so easy to break through."

"Oh, forget it, we're just asking." Expert Qin was quite straightforward, and then he said, "Then are you interested in going to the three provinces to guide our factory construction?"

"I've seen the design you drew for a 300-ton top-blown oxygen converter plant. It's very simple and crisp, with almost no redundancy."

"If you can help with the design, our factory's production efficiency will definitely be higher."

It is impossible for top-blown oxygen converters to have only large furnaces of 300 tons. The construction of small and medium-sized furnaces is also very necessary.

Otherwise, using only large furnaces can easily lead to waste of production capacity.

For example, the famous Taigang in later generations used the smallest furnace to produce a batch of ballpoint pen refills. Not only did it lose money, it was also laughed at by its peers. The refills could not be used up by the world in ten years.

"I'm afraid that's not possible. I'm busy with a lot of things here and can't get away. But if the two experts don't mind, I can help." Li Mu thought for a while and said.

Upon hearing this, both Expert Wen and Expert Qin showed disappointment on their faces.

Without an on-site inspection, even if Li Mu was willing to help, the effect would definitely be greatly reduced.

But the two did not force it and continued to discuss the technology and design issues of the top-blown oxygen converter with Li Mu.

It was not until it was getting dark and almost time for dinner that the two of them left one after another.

……

Time flies, and the aftermath of the Beijing Institute of Technology's early graduation exam has become insignificant in the face of the upcoming National Exchange Conference on the Steel Industry.

Without waiting for the meeting, professors and experts from all over the country gathered in groups of three or five and walked around the school talking and discussing the development of steel metallurgy in China and abroad.

It always attracts many students to stop and watch, and some with better knowledge can even say a word or two and put forward some opinions, which have been praised by many experts and professors.

However, when the meeting officially started, these students were still not allowed to go to the auditorium to watch, and could only learn about the content of the meeting from subsequent newspapers.

……

On the day of the exchange conference, guests gathered and a large number of banners were hung in the auditorium.

Before the meeting even started, the experts and professors below were already whispering to each other, with views and ideas colliding and sparks of human wisdom flashing.

In this era of relatively closed information, it is a blessing for everyone attending to have such a conference to exchange and learn.

So even though the host knew that the audience was a bit noisy, he didn't pay much attention to it. He just read out the polite words according to the script and then said:

"Next, please allow Li Mu to explain to us in detail the technical principles and research process of the top-blown oxygen converter."
