God-level Xueba system

"I forgot to introduce to Professor Will! This is the special professor of mathematics of our Dragon Academy: Yan Xin!"

Li Zhentian will naturally give Yan Xin face.

Will's speech just now was too crazy!

You said that you just kept talking about the content of scientific research and it's over, so you have to mock Long Xia's technology?

What a mouthful!

Li Zhentian naturally hoped that Will would make a fool of himself in public!
"Hehe, Academician Li, is it possible that your Academy of Dragon Sciences has such a small professor? Then your professorship title of Long Xia is also very well-received?" Will said with a disdainful smile.

The other professors who were in the same industry also laughed.

"Yo? In this way, the descendants of your country M are really not good! I just published a paper, which means that our descendants of Long Xia are really strong! You don't have a genius like me in your country M?"

In front of people she knows, Yan Xin has no need to pretend to be aggressive.

But in front of this kind of foreign pretender, how can he compare himself to Yan Xin?
Then he chose the wrong person!

"You! Hmph, we certainly have a lot of talents in Dalijian! But there is absolutely no one who speaks outrageous words like you!" Will said, pushing his glasses.

Yan Xin looked back at Li Zhentian.

After all, this was the topic Li Zhentian and the others were discussing. He joined in hastily, and even quarreled with Will. The rumor was not good for Li Zhentian's reputation.

But the old man Li Zhentian didn't care about Yan Xin's eyes at all!

OK!

It seems that this old man also acquiesced in his work!
Then I can't get used to Will!
"Oh? Outrageous words? Why did the professor say such words?"

Yan Xin smiled and looked at Professor Will, who looked down on people with dog eyes, and had to teach him a good lesson today!
"The new plan I proposed has been approved by many professors. Now I am here to talk to Academician Li Zhentian about the development. You think my new electrolyte is not innovative. You little professor really understands it. Batteries?" Will said.

Yan Xin smiled: "Battery? I don't know much!"

Will's glasses almost fell off his face!

This kid actually said that he didn't understand batteries?

So you are here to compare blindly?

How about entertaining me?
Li Zhentian smiled and glanced at Yan Xin, this kid started pretending not to understand again!
I don't know why, but he is full of confidence in Yan Xin, this kid will always surprise people!

"Although I don't understand, I have read related books! I also know a little about batteries!" Yan Xin replied with a smile.

"Oh? Then, can Professor Yan tell us what exactly is a battery? What are the points to be developed at present? And what's wrong with my innovation? If you can really tell me, I will speak out for what I just said. my apologies!"

Will expected that Yan Xin would not understand these things.

Just a teenager!

He can understand a fart!
I think back when I was in my teens, I was still in college, and other than picking up girls, I was going to clubs all day long!
I don't know how this kid got the title of professor!

Paid for it?

If this is the case, Long Xia's scientific research prospects are really worrying!

Yan Xin shook his head.

no way!
Since Will strongly asked himself to act aggressively, then if he didn't pretend, it would really be a disgrace to him!
"Okay! Then, please ask Professor Will to make room for me, and I will tell you what is called a battery, what is called innovation, and what is called our new technology in Longxia!"

Will thought that Yan Xin would stop talking if he said that.

I didn't expect this kid to let himself give way, and he wanted to come up and tell everyone?
This is obviously a slap in the face!
Now that Will has asked Yan Xin to explain what he said and the water that was thrown, he can only give way on his own initiative!
When listening to Will's lecture just now, Li Zhentai was almost bored to death, but after Yan Xin took the stage, Li Zhentian's eyes lit up!

Unexpectedly, this kid really has the courage to give a speech on stage!
Let me hear what he knows.

"Hehe, Yan Xin shouldn't be here, but Professor Will Richard from the University of Tennessee sincerely invited me, so I can't refuse! Next, I will tell you my own views on batteries!"

Yan Xin stood on the podium in the conference room and smiled confidently.

"A battery refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and a metal electrode to generate current. It is a device that can convert chemical energy into electrical energy. It has a positive pole and a negative pole."

"Are you kidding me? I think a junior high school student would know such simple and easy-to-understand knowledge, right? Why don't you talk about it?" Another professor named Rick Williams said disdainfully.

"No, the reason why I tell you this is to make you understand. After all, every time our professors in Longxia teach, analyze and research, they will start from the most basic knowledge points. This is also for the convenience of those who don't understand. Those who understand can understand! Could it be that the professors are all explaining in the field they are good at, and completely disregarding whether everyone understands or not? Isn't this...somewhat inhuman?" Yan Xin looked at Rick Williams with a smile Said.

Rick was told by Yan Xin that his face turned green and pale, and he didn't know how to refute him.

"Back to the topic! With the advancement of technology, batteries have also begun to refer to small devices that can generate electricity. Such as solar cells. The performance parameters of batteries mainly include electromotive force, capacity, specific energy and resistance. Using batteries as an energy source, you can Obtain a stable voltage, stable current, long-term stable power supply, and a current that is little affected by the outside world, and the battery structure is simple, easy to carry, easy to charge and discharge, and is not affected by the external climate and temperature. The performance is stable and reliable. It plays an important role in all aspects of modern social life."

Yan Xin paused, looked up at the expressions of all the professors who were working on it, and found that everyone still looked disdainful.

How much can a furry child know?

Also special professor?
Long Xia's teaching threshold is too low, isn't it?

In front of so many big names in the battery field, you just use such simple knowledge to speak?
"In a chemical battery, the direct conversion of chemical energy into electrical energy is the result of chemical reactions such as oxidation and reduction within the battery, which are carried out on the two electrodes respectively. The negative electrode active material is relatively negative in potential and stable in the electrolyte. The reducing agent composition, such as zinc, cadmium, lead and other active metals and hydrogen or hydrocarbons, etc. The positive active material is composed of oxidants with positive potential and stable in the electrolyte, such as manganese dioxide, lead dioxide, nickel oxide, etc. Metal oxides, oxygen or air, halogens and their salts, oxyacids and their salts, etc.”

While speaking, Yan Xin wrote the schematic diagram of the battery and the reaction formulas of the positive and negative electrodes on the blackboard on one side.

A group of foreign professors who had been mocking just now, seeing what Yan Xin said was the same thing, leaned on their chins and listened carefully.

"Hehe, let me talk about Professor Will's electrolyte problem next!" Yan Xin looked at Professor Will and smiled.

Will no longer had the confidence he had just now.

This kid is definitely not as simple as it seems on the surface!
He didn't have any reference materials or ppts in his hand, and he actually listed the reaction mechanism and chemical formula of the battery on the blackboard by relying on the memory in his mind!

From this point of view alone, Yan Xin must have a good understanding of the battery field!
