Great Power Ship

Chapter 255 The Fifth Generation

Not only Wang Jiahai is like this, but also Guo Yongwei who is beside him.

Although he doesn't know much about piezoelectric rubber, he also knows from Wang Jiahai's introduction that this thing is very important, especially in terms of military products. It can be said that it is a key core material. It stands to reason that such good things should be given priority It is supplied to users of military products such as the Navy.

However, Zhujiang Factory did not, but applied it to civilian products.

The problem is that your reasons are too surprising, and you actually say that today's piezoelectric rubber is too low-end.

The Soviets spent more than ten years but couldn’t make it, and finally gave up; the United Kingdom and France couldn’t hold it in for a long time, and they can only import things from the United States. Your Zhujiang factory thinks it is low-end?
If this is considered low-end, Guo Yongwei would like to ask, what is considered high-end, and what is considered high-end, and what is considered high-end!
Of course, Guo Yongwei can think about this in his heart and say that he dare not say it. After all, Fan Jiahang is the same generation as his teacher, and he is also the leader of Zhujiang Factory. Tai Sui broke ground on his head.

But he couldn't, his teacher didn't have so many worries, and pointed at the piezoelectric rubber that had already been produced, staring and said: "Old Fan, you say this is a low-end product? Are you sure you're not bragging?"

Fan Jiahang did not answer directly when he heard the words, but led Wang Jiahai and Guo Yongwei to leave the piezoelectric rubber production workshop. After all, it is not good for outsiders like them to stay in this clean room for too long. Qualified, outsiders like them really can't tell.

So Wang Jiahai and Guo Yongwei didn't refuse either.

Following Fan Jiahang and leaving the workshop, Wang Jiahai couldn't bear it any longer, and asked eagerly: "Old Fan, don't play tricks on me. Piezoelectric rubber is already the latest advanced acoustic conversion material in sonar in the world today. It would be a waste if you don't use it in military products first~~~"

When Wang Jiahai said this, his face was heartbroken. There was nothing he could do. The technical level of domestic submarines was really not flattering, especially in terms of situational awareness. 5.0 gap between the stick guys.

Not on a level at all.

So Wang Jiahai didn't believe that Fan Jiahang, who was a submariner, didn't know this.

But when Fan Jiahang heard this, a faint smile appeared on his face in Chinese characters: "Old Wang, are you sure that piezoelectric rubber is really the most advanced acoustic conversion material for sonar?"

"Isn't it?" Wang Jiahai asked back.

"Then it seems that your research institute is obviously lagging behind!" Fan Jiahang was a little rude, Wang Jiahai's face darkened, but before he could fight back, Fan Jiahang said: "Do you know polyvinylidene fluoride?"

"Polyvinylidene fluoride...?" Wang Jiahai couldn't help but frown when he heard Fan Jiahang's words, but he opened his eyes wide the next moment, and looked Fan Jiahang up and down for a long time, and then he seemed to reacquaint himself with the old colleague in front of him. He said softly, "Have you reached this point?"

"It's been almost half a year, and it's progressing in an orderly manner. Specifically, it's led by Comrade Wen Dawei, our executive deputy factory director and senior party official. His doctoral research direction is this, and the nervousness is going well!" Fan Jiahang said with a smile: "Today's technical demonstration meeting in the factory is to discuss relevant experiments in this area. Once formed, the energy consumption of the sonar array will be reduced by 56%, the sensitivity will be increased by 80%, the overall mass will be reduced by 62%, and the detection distance will be increased by 100%. Immediately following the background noise of the seabed, the probability of finding a silent submarine in the future will increase by 75%..."

"kindness……"

Wang Jiahai nodded when he heard the words: "This is already a very conservative estimate. I read a related paper by an American scholar before. This brand-new underwater acoustic conversion material is very effective. They are only in the initial stage of experimentation. think……"

As he said that, Wang Jiahai raised his eyes and looked at Fan Jiahang in a complicated way: "I never thought that you could synchronize with the United States!"

If he hadn’t come to the Zhujiang factory, or even gone to the dust-free workshop just now, and told Wang Jiahai that the so-and-so factory kept pace with the latest frontiers of the United States in terms of acoustic materials.

Wang Jiahai couldn't say anything in the end, but he promised in his heart that he would be able to criticize the other party as a second idiot.

You don’t even piss and take a good photo of yourself. The ancestral grave in your factory is smoking. Can you synchronize your research and development direction with the United States?
You must know that it is the United States, the world's technological overlord, and the global technological empire. If you take out any thing, it can leave you in China for 30 to [-] years. How dare you say that it is on par with others?
I bah~~~~
However, when he arrived at the Zhujiang factory, especially after seeing the dust-free workshop just now, it was impossible for Wang Jiahai to believe it or not, because those advanced equipment and instruments cannot deceive people, because the orderly production links cannot deceive people, because The finished products produced one by one cannot deceive people.

That is to say, the Zhujiang factory really rushed into the same track with Da Laomei on the opposite side of the Pacific Ocean in this field.

What does this mean?
The technical strength of the Zhujiang factory is not covered, it is really awesome!
"Forehead……"

Just when Wang Jiahai was feeling emotional, he suddenly heard his student Guo Yongwei ask in a low voice: "Teacher, what did you just say? I didn't quite understand it!"

How wrong was Guo Yongwei in saying this? Just now, Guo Yongwei understood every word of what Wang Jiahai and Fan Jiahang said back and forth, but when they were together, they became confused.

It's like a rookie who just stepped into the rivers and lakes, seeing two martial arts masters competing in martial arts, the eyes are so dazzled that they can't understand at all.

As for digestion, let alone, there is no such ability at all.

Fortunately, Guo Yongwei has a temperament of asking questions when he doesn't understand, so he quickly asked his teacher in a low voice, but before his teacher could speak, Fan Jiahang smiled and explained:
"There are several generations of piezoelectric materials used for acoustic conversion, the first generation of piezoelectric quartz stone during World War I; the second generation of piezoelectric ceramics during World War II; the third generation of piezoelectric ceramics that emerged in the 50s; The fourth-generation piezoelectric rubber developed in the late 70s; and the polyvinylidene fluoride we just mentioned is the fifth-generation piezoelectric material for acoustic conversion!
The relevant theory was proposed by California Institute of Technology in the early 80s. Currently, several heavyweight laboratories in the United States are conducting related experimental research, and our Zhujiang factory is the first unit in China to carry out related research. "

While talking, Fan Jiahang looked at Guo Yongwei with a blank face, and continued meaningfully: "The leader is Comrade Wen Dawei, our executive deputy factory director and senior party official, who is about the same age as you. If you can, you can join his team, Comrade Wen Dawei The team he leads is a group of energetic young people, many of whom have just graduated from university, and the average age is less than 32 years old. If you go there, you will find a lot of common language..."

　I have to go to the hospital to change the dressing today. Urticaria is really troublesome, so Chapter 2 is put in the evening, and Chapter 3 is in the evening. Sorry...
