Let you change the Hongqi h9, not the Hongqi missile vehicle

Professor Zheng didn't wait for Jiang Chen to react, and excitedly pulled him towards another supply room.

Jiang Chen was still in a daze when Professor Zheng pulled him to another password door.

"Jiang Chen, you also know that the weapons and equipment of our military region are confidential and involve military secrets."

"I can't show you the finished products either."

"But I still have a finished product here, or rather a defective one."

"See if this helps you."

Professor Zheng said to Jiang Chen excitedly while scanning the pupil.

If that crude electromagnetic device was helpful to Jiang Chen, then Professor Zheng felt that another device that he had eliminated might also be helpful to Jiang Chen.

After all, that piece of equipment was originally designed to work with electromagnetic equipment.

Ok?
After hearing what Professor Zheng said, Jiang Chen stopped struggling.

Any other equipment?

Although Jiang Chen didn't know what the device was, it wouldn't hurt to take a look.

About ten minutes later, Jiang Chen and Professor Zheng walked out of the armory side by side.

"How is it, Jiang Chen? Did the equipment disappoint you?" Professor Zheng asked expectantly.

"Our institute invested a lot of manpower and material resources in that equipment. Unfortunately, we encountered technical difficulties and failed to complete the final research." There was a hint of regret in Professor Zheng's tone, but his face was still filled with pride.

After all, their institute was the first to take the lead in that project nationwide, and they have made remarkable progress. Many of today’s technologies are derived from their research results.

Although they had to transfer this research to other research institutes in the end due to various reasons, Professor Zheng still hoped that Jiang Chen could help him complete this unfinished business, which could be regarded as a kind of fulfillment for himself after all they had poured countless efforts into it.

"Of course it helps, and it helps a lot." Jiang Chen responded with a smile. The equipment was undoubtedly the icing on the cake for him.

Professor Zheng's research was actually quite mature, and he only needed to make some minor changes to perfect it. More importantly, that piece of equipment was a perfect match for electromagnetic weapons.

"Professor Zheng, once the equipment you designed is put into use, it will completely change the pattern of individual combat. It can even be said to be an epoch-making masterpiece." Jiang Chen gave a high evaluation without hesitation.

Professor Zheng laughed so hard that he couldn't stop. "Hahaha, thank you so much, Jiang Chen, you are too polite. It still depends on you to make this equipment truly available to the public."

As a leader in the domestic military industry, Professor Zheng has heard countless praises, but Jiang Chen's praise made him particularly happy, because Jiang Chen was sincere, and as a military genius, his recognition was undoubtedly the greatest affirmation of his own research.

The two of them walked into the lobby of the institute, chatting and laughing.

Hearing Professor Zheng's hearty laughter, the researchers put down their work and looked towards the entrance curiously.

Professor Zheng was seen wearing a research coat, walking out side by side with Jiang Chen, with a smile on his face.

Looking at Professor Zheng's rare smile, the researchers didn't say anything, but their eyes revealed a little disdain for Jiang Chen, and they whispered in private: "Flatterer!"

They didn't hear what Jiang Chen said, but from their expressions and actions, it was not difficult to guess that Jiang Chen was definitely trying to flatter Professor Zheng.

"Professor Zheng, you're back." The researchers gathered around him, notebooks in hand.

"I'm back, I'm back." Professor Zheng responded with a smile, "Are you ready for the questions I asked you to prepare? There aren't many opportunities to ask Jiang Chen for advice, so you have to cherish them."

"Any advice from Jiang Chen will benefit you a lot. Pay attention!" Professor Zheng said solemnly and invited Jiang Chen to the first seat.

"Yes, yes, yes, don't worry, Professor Zheng. We will definitely consult this young military master!" The researchers agreed verbally, but their eyes revealed some ill intentions.

Ask for advice? Humph, they want to see how powerful this Jiang Chen is that Professor Zheng values ​​him so much.

"Okay, then who will ask questions first?" Professor Zheng saw that everyone was very enthusiastic and stopped talking.

"I'll do it, I'll do it!" A young researcher raised his hand impatiently. He had long been dissatisfied with Jiang Chen. How could a student younger than him win the favor of Professor Zheng? He had worked so hard to get into this institute.

"Jiang Chen, my question is very simple. In military production, the thickness of the coating or anti-corrosion layer of products and metal components is an important indicator of product quality and performance. Coating thickness measurement is an indispensable part of military equipment manufacturing and is a necessary means to ensure product quality." "Then I would like to ask, Mr. Jiang Chen, what are the main measurement methods of the coating thickness analyzer?" The young researcher asked contemptuously, and others also turned their eyes to Jiang Chen.

Although this question is basic, it is impossible for laymen to answer it. This question will reveal whether Jiang Chen understands military technology. If he can't even answer this question, then there is no need for them to continue asking questions.

Professor Zheng, who was sitting next to Jiang Chen, suddenly looked down on his smiling face and looked at the young researcher unhappily. He had finally fought for this opportunity, but this guy asked such a simple question right after he arrived? Isn't this just making trouble?
But since the question had already been asked, Professor Zheng couldn't say anything else.

Jiang Chen remained calm when he heard this question, and replied calmly: "The main methods for measuring coating thickness include wedge cutting method, light interception method, electrolysis method, thickness difference measurement method, weighing method, X-ray fluorescence method, beta ray backscattering method, capacitance method, magnetic measurement method and eddy current measurement method."

"The first five are destructive tests, which are cumbersome and slow to measure, and are mostly used for sampling inspection. The X-ray and β-ray methods are non-contact and non-destructive measurements with a relatively small measurement range. The X-ray method can measure extremely thin coatings, double coatings, and alloy coatings; the β-ray method is suitable for measuring coatings with atomic numbers greater than 3 on the coating and substrate. As for the capacitance method, it is mainly used to measure the thickness of thin conductive insulating coatings."

With the rapid development of science and technology, especially the introduction of microcomputer technology, X-ray coating thickness analyzers have taken a big step towards becoming more miniaturized, smarter, more comprehensive, more accurate and more practical.

Its measurement resolution has been refined to 0.1 micron, and its accuracy has reached an astonishing 1%, achieving a qualitative leap. It is widely used, has a wide range, is easy to operate and is affordable, so it has become the most commonly used thickness measuring instrument in the industrial and scientific research fields.

After Jiang Chen listed all the commonly used methods fluently and accurately, he looked up at the young researcher and asked casually, "Do you need me to explain the basic principles of the X-ray fluorescence coating thickness analyzer to you?"

This stunned the young researcher. He was at a loss in the face of this series of professional terms, and could only look back helplessly at his senior brothers and sisters behind him. He had never heard of many of the methods mentioned by Jiang Chen.

"A Qiang, come back. What Mr. Jiang Chen said just now is correct." An older researcher walked up and patted the young researcher on the shoulder gently, but his eyes were fixed on Jiang Chen.

Read the error-free version at 69shuba! 6=9+shu_ba is the first to publish this novel.

This young man seemed to be more than just a show-off. Perhaps, as Professor Zheng said, he really had some knowledge of military industry. At this age, it was quite rare for him to know these methods, and he could also accurately point out the applicable scenarios of various methods. Obviously, he was not an ordinary person.

However, these basic knowledge alone are far from enough. Although the attitude of the crowd towards Jiang Chen is no longer so contemptuous, it is not respectful either.

"Mr. Jiang Chen, I would like to ask a question next." The older researcher said, his eyes shining and looking particularly serious.

"Go ahead." Jiang Chen nodded. Professor Zheng had given him so much help, so it was his duty to answer a few questions. Moreover, these questions were a piece of cake for him.

"Mr. Shen, you also know that our country has suffered a serious technological blockade in the field of national defense and military equipment from Western countries led by the United States. This includes almost all high-end technologies of the navy and air force, such as advanced air-to-air missiles, long-range air search radars, and tank main gun armor-piercing shell material formulas, which are all key technologies that were strictly blocked by the United States at the beginning of this century."

"What I want to ask is what are your opinions on the material formula of tank main gun armor-piercing projectiles? Especially our tank, which has been modified by the military master, has a barrel diameter that is more than three times larger than that of ordinary tanks. But after our research, we found that with the existing material technology, it is impossible to manufacture a barrel of such a large size that can meet the performance requirements."

"Excuse me, do you know what material this tank's barrel is made of? And how can I obtain this material?"

After saying that, the older researcher walked to the central tank and gently patted the barrel. The research on this tank had given them a lot of headaches, and the biggest problem was the material of the barrel. The existing materials simply could not meet the requirements, and if they were forced to manufacture it, cracks would appear after a few uses, and it might even explode.

These PhDs in materials engineering tried everything but could not find a solution. If they had not seen the tank right in front of them, they would have found it hard to believe that someone could have built such a tank. They tried to collect samples for chemical analysis to explore the composition of the material, but strangely, they could not collect any samples at all, as if the material was naturally formed.

Everyone shook their heads, not expecting the researcher to ask such a tricky question. Even Professor Zheng was at a loss for words, so how could this young man know the answer? This was clearly a deliberate attempt to embarrass him.

Although they also wanted to verify whether Jiang Chen was really as powerful as the legend said, it seemed a bit unfair to test him with this question. After all, they themselves could not solve this problem, so even if Jiang Chen did not know the answer, it did not mean anything.

However, Professor Zheng, who was sitting next to Jiang Chen, was all smiles. He was actually expecting someone to ask this question. He originally wanted to ask Jiang Chen directly, but as the director of the Yanjing Research Institute, he felt that it was a bit embarrassing to ask Jiang Chen a question in front of the researchers. Now, someone asked the question for him.

Jiang Chen glanced at the researcher, then at the tank he had modified, and finally looked at Professor Zheng helplessly. Didn't Professor Zheng tell them that he had modified the tank? Since he could build it himself, how could he not know what materials were used? This question was too ridiculous!
Seeing Jiang Chen remained silent, everyone thought he didn't know the answer either. The researcher secretly breathed a sigh of relief. He felt that this question was enough to verify whether Jiang Chen was really as amazing as the legend said. If Jiang Chen could answer it, his colleagues wouldn't have to embarrass him anymore. But now it seems that he was worrying too much. Although this person knows some military knowledge, he is obviously not a military industry master.

"Brother Bai, you should change the question. This question is too difficult. Even Professor Zheng hasn't figured it out. How could a college student like him possibly know the answer?" Someone in the crowd said sarcastically.

However, as soon as he said this, Jiang Chen immediately turned around and looked at Professor Zheng. What's going on? Professor Zheng also didn't research the materials he used? This shouldn't be the case! This kind of material is not difficult to obtain in theory! Jiang Chen looked at Professor Zheng in confusion.

Professor Zheng's smiling face instantly turned livid, and he glared at the researcher who spoke in the crowd. If looks could kill, that researcher would have been killed thousands of times by him. Professor Zheng could only smile awkwardly and look forward, not daring to look Jiang Chen in the eye. Although he knew that his military technology was not as good as Jiang Chen's, he still felt a little embarrassed to be exposed in public by his own researcher.

Jiang Chen coughed twice, and seeing that Professor Zheng's smile had become stiff, he withdrew his gaze. "Ahem, actually, this material is nothing special..."

As soon as these words came out, the researcher surnamed Bai who was about to ask a question was stunned. Nothing special? The others also looked up at Jiang Chen in surprise. This young man was too arrogant! Nothing special? So many military researchers have been studying this for more than a month and still can't figure out what this material is. But when Jiang Chen said it, it became nothing special? Isn't this a disguised way of calling them good-for-nothings?
"Jiang Chen, you should know your limits when bragging! Do you know what this material is? How dare you say it's nothing special!"

"That's right! That's right! Do you know how difficult it is to maintain a balance between the hardness and ductility of the barrel? Don't you think carefully before you brag?" Everyone accused Jiang Chen.

After hearing Jiang Chen's words, everyone was instantly shocked and expressed disbelief.

They had seen many arrogant people, but this was the first time they had seen someone as arrogant as Jiang Chen. You know, the tank was the crystallization of top technology, but he looked down on it.

Everyone felt very upset, thinking that Jiang Chen was simply ignorant of the immensity of heaven and earth. As researchers, they regarded research as their life, but now someone was belittling their hard work. If Professor Zheng had not been present, they really wanted to kick Jiang Chen out.
