Qi Gongxun took the opportunity to send Professor Wu off and locked the door with his sideways cover. Pen ~ fun ~ pavilion www.biquge.info

This casual action did not escape Li He's eyes, since they came in the name of the magazine editor, they didn't want people to know.

Li He is also happy to pretend to be confused, entering this whirlpool, it is not so easy to escape, and dedication to the country does not necessarily have to work hard in Lop Nur.

The bearded Guo Dong politely poured a glass of water for Li and said with a smile, "Teacher Li, I didn't expect you to be so young, we didn't expect it." Our "Weapons Knowledge" is a journal and magazine sponsored by the Ordnance Industry Association and supervised by the Association for Science and Technology. We would like to do a study on the development trend of rocket artillery recently, and we hope to ask you for advice."

Li He has a deeper understanding of Guo Dong's ability to close his eyes and tell nonsense, but he still smiled on the surface and said, "You're polite, you can study each other and make progress with each other."

Qi Gongxun asked, "You seem to know a lot about our army's Type 70 130mm self-propelled rocket launchers, because the 130 rocket launchers were only transferred to mass production in 79 and officially equipped with our army's armored troops." And our weapons magazine is in the principle of secrecy about the new weapon, and does not introduce it too much, how do you know about it?".

Qi Gongxun's question was meaningful, and Li He's brain immediately turned a hundred times before he secretly scolded himself for being a pig's brain, why did he make such a low-level mistake, so he had to calm down in his heart and ask rhetorically, "It's not a secret that Type 70 uses Type 63 armored vehicles as weapon platforms, right?"

Qi Gongxun and Guo Dong glanced at each other and said with a smile, "This is well known."

"Rocket artillery consists of a directional device, a rotary disc, a high and low machine, a steering machine, a marching fixture, an aiming device, a leveling device and a firing system, etc., and there is nothing complicated in terms of structure. And since the Type 63 is used as a platform, in order to meet the needs of loading, part of the structure of the gun needs to be changed. During the counterattack against Vietnam, the People's Daily reported on the battlefield that included the Type 79, in which the mounting position of the sights was changed, the high-low machine and the steering handwheel were rearranged, and the level mount was set on the chassis body, and the level seat on the rotary body was canceled. As long as you know a little bit about rocket artillery, you can see it, right?".

This Li He didn't lie, he really saw the 79-style photo in the newspaper.

The two of them nodded approvingly again.

Li He continued, "And the anti-aircraft machine gun on the top deck has been replaced by rocket artillery, if I can't tell the difference between the overhead machine gun and rocket artillery, am I not a fool?"

After Li He finished speaking, the two of them laughed.

Li He knew in his heart that this was a fool.

Guo Dong asked again, "Do you think the development trend of rocket artillery is self-propeling?"

This is a trend, but not an obvious one, because the first generation of Soviet rocket artillery "Katyusha", which showed its might in World War II, was mounted on a five-and-a-half-ton truck, and almost all of the rocket artillery used by the warring countries in World War II also had self-propelled rocket artillery. I think the future trend is not only self-propelling, but also being able to achieve long-range strikes, at least more than 70 kilometers. The second is high guidance accuracy. The third is large firepower, multi-barreled salvo. If you can't do the above points, the position of the rocket artillery will be awkward."

"Why?", this time it was Qi Gongxun who interjected.

"There are missiles for precision strikes, and artillery for fire attacks, why do you need rocket artillery?", Li He took a sip of tea after speaking, and when he entered the door, his throat was already uncomfortable, and he thought that it might be a cold.

The more the three of them talked, the happier they became, but Li He deliberately kept an eye on it, saying some obvious mistakes in some places, and then asked the two of them to correct them in a serious manner.

"In your paper, you mentioned the application of structural dynamics and structural optimization theory to study the launch dynamics of rocket artillery and the matching analysis of the dynamic characteristics of each component to achieve the purpose of reducing the initial disturbance. This involves a finite element model that simulates the original structure. Can this finite element analysis give us some popularity?", Guo Dong's questions seemed to be getting deeper and deeper, beyond the scope of an editor's knowledge.

Li He knew that he couldn't answer any longer, otherwise he would not have a good life if he was remembered, so he pretended to scratch his head helplessly and said, "This is embarrassing, after all, I have only studied high mathematics for four years, and my ability is limited." But don't be embarrassed, the country will grab a lot of these. Our principal is an expert in fluid mechanics, and finite element analysis is commonly used to build a three-dimensional model. Moreover, when our domestic road engineering construction encounters soft foundations, finite element analysis is also indispensable. There is also the construction of our bridge, such as the Yangtze River Bridge, which is also the finite element method for the analysis of the roll stability of the combined system."

"Really?", Qi Gongxun asked uncertainly.

"Of course it's true, what I know is a half-understanding from periodicals and newspapers", Li He doesn't know how much he sighed when he was reborn, sometimes there is no shortage of experts in certain aspects in China, what is lacking is the resource integration of certain research results and projects, I don't know how many people are doing repetitive research, and how much waste of resources has been formed.

In the field of science, the United States is actually acting on the socialist model, concentrating its efforts on big things, and if it disagrees, it will carry out a "Manhattan Project" or a "moon landing program."

Every time the two of them asked some questions, Li He would rack his brains to recommend some experts or published journals and magazines.

In the end, when the two of them racked their brains and couldn't think of any problems, this conversation was the end of the show.

Guo Dong excitedly gave Li He a bear hug, "Teacher Li, thank you very much for your help, in order to express your gratitude, please drink."

"Yes, Mr. Li, you are familiar with the place, you choose a place, let's have a few drinks", Qi Gongxun also pulled Li He and asked to go to the hotel together.

Li He is capable, they are curious Teletubbies, but he is not a good star, he doesn't want to continue to deal with it at all, it is important to escape, and said righteously, "Thank you two editors, I also want to accompany the two of you to do the friendship of the landlord, but tomorrow's lesson plan has not been prepared yet, and it is about to be the end of the term, and things are more complicated." I hope you both understand that as a teacher, I need to be responsible for my students first and foremost."

The two of them immediately said that they understood, and gave Li He a label of dedication and responsibility.

Li He walked out of the office door like this and took a hot breath.

Maybe you really have a cold, dizziness, sore throat, and astringent eyes. After clearing the snot, the eye circles turned red. He said to himself: "I don't know what kind of life I did evil." “

I went back and drank a large glass of boiling water, didn't buy medicine, didn't eat dinner, was chilling, covered with two thick quilts, and pressed Li He with his head as heavy as a grinding plate.

Although Li He didn't sleep, Li He couldn't wake up, and the heaviness made Li He unable to raise his head.
