My 1979

As graduation approaches, it’s time to start preparing for your graduation thesis.

Graduation thesis is a fool's errand. It is a piece of cake, has no creativity, and has mediocre results. Without originality, it is absolutely impossible to pass.

And the grades are divided into excellent, good, and passing, which are directly related to the graduation assignment, but no one should take it lightly.

In fact, the choice of thesis topic became less and less important later on. There were many students who wrote their graduation thesis on Marx and expounded his thoughts lucidly, but later went to work for big capitalists.

The professor's topic selection was randomly assigned, and Li He's assignment this time was obviously different from his previous life.

Li He was assigned to Professor Wu Quande, director of the Electronic Physics Teaching and Research Office, and needed to go there to choose a topic.

Professor Wu is the founder of electronic physics. During the War to Resist US Aggression and Aid Korea, the Volunteer Army seized a strange weapon from the Yankees, but did not know its purpose. At that time, Professor Wu of the Military Commission conducted research and found out that it was an infrared night vision goggle. Can target the human body.

Wu Quande not only cracked the secret of infrared, but also made the same infrared night vision goggles himself, which was a remarkable achievement at the time.

Li He can only admire and admire it. In the future, this kind of thing can be produced by any copycat panel or LED factory. At this time, he doesn't know how much effort it will take step by step.

I didn't know who was in the same group as me, so I went to the Electronics Department alone to find Professor Wu, knocked on the door and went in. Professor Wu was immersed in writing something at his desk.

He stood aside for a while, and when he saw no response from the other party, he had to say, "Professor Wu, I'm here to choose a topic."

Professor Wu raised his head and said, "Why did I give you the research topic? The topic is for you to study and sort out the insights. If I have a good topic, why can't I write it? Why do I give it to you?"

Li He knew that this old man had a temper that always told the truth, so he had no choice but to say, "Isn't this the school's practice? If I can make my own decision, I will definitely give myself an excellent grade."

Professor Wu suddenly smiled again and said, "You sleep every day in my class. If I hadn't seen you studying well, I would have caught you and scolded you every day. Your advanced mathematics is not bad, why don't you think about interdisciplinary subjects? Selected topics, such as a type of development equations, deformation of spectra, and compressed images, all require high-level mathematics to solve.”

After hearing this, Li He almost cried. He couldn't help but touch the cold sweat on his head. These are huge pits. Even if you know the conclusion, it is useless without a large amount of detailed experimental data. I can't write it out either, which means I have to stay in the laboratory for a month or two and don't have to do anything before graduation.

For people like Li He who can lie down and never sit down

I would never jump into this pit easily as a last resort, so I hurriedly said, "Can you really choose your own thesis topic?"

"Of course, I can still lie to you, but the topic you write must be approved by me." When Li He was really asked to choose his own topic, Professor Wu hesitated.

Li He thought for a while, then gritted his teeth and said, "My topic is the study of launch dynamics of rocket launcher systems."

Professor Wu said doubtfully, "This is a big question. If you can't write it well, you will fail. Have you thought about it?"

Li He nodded. This was his specialty. If he failed to write, he might as well kill him with a piece of tofu. He said directly, "I've thought about it. This is the topic. I won't change it."

Li He chose this topic to make up for his own regrets. He may not have the opportunity to see old colleagues and friends in this life, but it does not prevent him from making some contribution silently. I remember that in 1983, when I first started working, the People's Liberation Army was fighting Vietnamese rocket launchers at the border. The General Staff issued a task to develop a new generation of rocket launchers that could meet the needs of the battlefield.

At that time, young newcomers like him were too tired to stand up straight, and even suffered from stomach problems for a while at a young age, let alone researchers in their fifties, sixties, or even seventies or eighties.

There are three main indicators to evaluate whether a rocket is advanced, namely range, accuracy, and power.

Research at that time was very difficult, and I don’t know how many research meetings were held. The simplest one, such as the solid rocket motor casing, used seamless steel pipes imported from Laomaozi. Both the inside and outside needed turning. This kind of steel is hard, tough, and very It's not easy to process, and it makes a lot of people angry.

A group of people had food and accommodation next to the machine tool. Li He was single at the time, so it didn't matter, and his body could withstand it. However, there were many people who were raising families and were not in good health. They gritted their teeth and endured it. These people are really convinced.

The hard work and perseverance of this group of people allowed the Chinese rocket artillery to develop to its extreme, which is simply crazy and outrageous. In this field, the Chinese believe that they are second, and no one dares to believe that they are number one.

There was a chapter in the political class called "Human Subjective Initiative".

To put it crudely, Diao Si can counterattack if he works hard. For example, if you have no money, no car, no house, a father and a mother, but as long as you are diligent and motivated, you may not be happy to be a father. Such a case happened with Chinese rocket launchers, and it actually destroyed all rocket launchers in the world.

It is really unimaginable that Xiaokai, who is extremely poor, would push Gao Fushuai.

In the end, many old rocket launchers were packed up and started to make money and marketed them all over the world.

Li He prepared this paper focusing on rocket launcher dynamics analysis and structural lightweight research. In fact, it closely follows the parameters of the Type 89 rocket launcher.

As for the more advanced 40-tube wheeled rocket launchers later, don't worry about it. These involve automatic operation systems, including director, special computers, sensors, software, etc. Currently, there are no such conditions.

Seeing Li He's insistence, Professor Wu took out a form, wrote Li He's name and the title of the paper, and then said, "Please give me a question first. If you can't finish writing, you will have the opportunity to change your choice before answering the question." question, otherwise it will be too late.”

Li and the next period of time began to go to the library to write papers. Writing a thesis may take several months for the average student, otherwise there will be no substantial content at all.

However, it was not difficult for Li He to write the content at all. He was familiar with the work and revised it three or four times. It only took a week and he wrote more than 40,000 words.

But the most annoying thing for him is sorting out the literature index. From the perspective of materials and papers, literature is indispensable.

When other people write papers, they search literature first and write the paper second. His writing steps are reversed from others.

The library is still in the traditional hand-made card format, and it is very troublesome to find documents and periodicals, especially foreign language documents.

However, when Li He was struggling to find documents in the library, a linguistics buddy next to him seemed to be even more miserable. After sitting next to him for a few days, the two became somewhat familiar with each other.
