"Xinyi, we can go back today." Conan replied in a low voice, "Okay."

"How is your black friend?" Yukiko asked curiously. "It has recovered." Conan replied. Although a little decadent at first, Hattori Heiji is worthy of being a Kansai detective.

Quickly cheered up.

Discuss the case with Conan again, and the Black Organization. .

Chapter 305 Plasma (Supplement to Chapter 4)

"Senior Sagawa, call more frequently."

At Osaka Station, Kazuha waved goodbye to Yan Sagawa.

"Well, call me if you have something to do, and I will come to play often."

Sagawa Yan also bid farewell to Kazuha, and it was true what he said about coming here often.

It only takes a while to travel from the eastern capital to Osaka by using the earth escape technique.

Even if you don't use Tudun, just take the Shinkansen, it only takes more than 2 hours.

You can even go in the morning and come back in the evening.

Reluctantly saying goodbye to Kazuha, Sagawa Yan and others took the Shinkansen back to the eastern capital.

Compared with the journey where many incidents happened when we came, the way back seems to be uneventful.

Sagawa Yan felt that he was just chatting with Xiao Ai, Akemi, and Yukiko on the seat.

I have already returned to Dongdu from Osaka.

"Well, Yukiko, see you next time."

"Okay, Xiao Ai, Mai, see you next time" Yukiko said to Sagawa Yan and the two little lolis.

A group of people also officially separated to go home.

On the way back, Sagawa Yan asked Xiao Ai and Ming Mei. "How do you feel about going to Osaka this time?"

Xiao Ai raised her head and looked at Yan Sagawa who seemed to be asking a serious question.

She thought for a while and replied, "It's pretty good. Both Osaka Castle and Tsutenkaku have the feeling of ancient warriors." But immediately, Xiao Ai showed a half-smile expression again.

"But the most exciting thing is seeing someone's hero save the beauty, and the scene where the girl named He Ye throws herself into her arms." Sagawa said with a very thick skin.

"Actually, in the train compartment, you two sisters blushed very touchingly." When this was mentioned, the two sisters blushed. "Yan, you still dare to mention that."

Mingmei looked at Sagawa Yan with a 'vicious' look.

"Sister, you were so powerful when you restrained me." Xiao Ai said quietly.

"Xiao Ai, I'm sorry," Mingmei said flatteringly to her sister.

The three of them talked and laughed and returned to their home. "It's still comfortable at home." Sagawa Yan said as soon as he entered the room.

At this time, Xiaolan, Yuanzi and Ayako were not at home.

Sagawa Yan took a rest on the sofa. Sagawa Yan came to the study in the afternoon.

"I'm back, and it's time to study again."

After returning from playing and relaxing, Yan Sagawa is now full of motivation.

He took out the manuscript paper and wrote down the title first.

"Plasma Destruction Reality Model and Its Physical Derivation"

Plasma, almost all research on controllable nuclear fusion cannot avoid plasma.

The reason is simple, as long as the temperature is high enough, electrons will be separated from the atoms, and the fourth state of matter, the plasma state, will appear.

Nuclear fusion is based on this.

Under the terrible high temperature, the extranuclear electrons of the tritium atom get rid of the shackles of the nucleus and become a plasma state. The two nuclei can attract each other and collide together, and the nuclei are aggregated to form a new heavier nucleus helium.

Huge amounts of atomic energy are released in the process.

These atomic energies are just what people crave!

The omnipotent atomic energy can be used to generate electricity, to be used as a power source for aircraft carriers, to replace oil and coal as energy... In a word, it can do everything!

Sagawayan's paper is just trying to establish a mathematical and physical model for the moment when the plasma shatters at high temperature.

He thought quietly, and slowly wrote the first paragraph.

But after a while, it was erased again.

As his first step in nuclear fusion, what he asked for was enough stability.

As time passed, Sagawa Yan's pen did not come down.

In his mind, he is constantly simulating and deriving.

1 hour, 2 hours...

Yan Sagawa wrote the first paragraph of the paper.

Then re-enter thinking again.

When Xiaolan, Yuanzi and Ayako came back.

He also wrote only three paragraphs on the manuscript paper.

But on the contrary, in his mind, he had already deduced a long process. "Next, it's time to write down the derivation process of the first stage." Sagawa said to himself.

The speed suddenly increased.

Rows of formulas, smooth derivation process, generation and change of related functions.

Appeared in Sagawa Yan's pen.

recorded on paper.

One page, two pages.

His thinking is smooth, and the relevant process of each step is clearly visible in his mind.

It took an afternoon to write 3 paragraphs.

Then spend 1 hour and write the 3-page derivation and proof process!

"Yan, you are back." Xiaolan said happily.

Although it was only two days without seeing each other.

But they have been together since the summer vacation started.

Xiao Lan is really not used to not seeing each other for such a long time. . . . . Ask for flowers. . . .

But this time, Sagawa Yan was stunned for a while, so he had no choice but to reply. "Well, we're back, Xiaolan, Sonoko, Ayako" he said to the three girls with a smile.

"Hey, you answered so slowly today, are you thinking about something bad?" Sonoko smiled happily.

Both of them had just returned from club training. Although they were very tired physically, they were in a good mood when they saw Yan Sagawa.

Yan Sagawa temporarily put aside his thoughts about the thesis.

"It's really a bad thing, for example, who will accompany me at night." He returned to his usual look and teased.

As soon as these words came out, Xiaolan Yuanzi couldn't stand it immediately.

"Yan, what are you talking about?" Xiao Lan said angrily.

"It's okay, Xiao Ai and Mai are not here."

Sagawa said indifferently.

Sister Xiaoai was a little tired, and she was still resting in her room.

Ayako blushed, she was not a complete woman yet.

"Yan, Yuanzi, I'm going back to my room first, call me after dinner."

Seeing Ayako's sister running back to her room in a hurry, Sonoko was also a little embarrassed. "Yan, it's all your fault, you scared Miss Ayako." "It seems that you are not scared." Sagawa Yan smirked.

"By the way, Yan, I think you seem to be thinking about something?"

Feeling that the topic was going in the wrong direction, Xiaolan hurriedly changed the subject. "Oh, a little academic matter." Sagawa Yan said, without saying too much.

After all, he didn't think Xiaolan and Sonoko would be interested in the process of how the nucleus turns into plasma at high temperature and how it shatters. "Have you started a new scientific research content?" Xiaolan and Yuanzi were a little surprised.

My boyfriend is too good, causing a bit of pressure, why wait online, urgent. "You guys are serious too." Sagawa Yan looked at Xiaolan and Sonoko.

Obviously after a lot of hard training, the fatigue on the two of them can be seen with the naked eye.

"Haha, I can't help it. Sister Shumei gave me the karate society. I can't let her down." Xiaolan smiled firmly.

"Me too, this is my last chance." Yuanzi was full of fighting spirit.

"In that case, let's work together!" Sagawa Yan stretched out his palm.

Snapped.

"Well, let's work together!"

The three of them gave each other high fives to encourage each other. predict.

Chapter 306 Plasma in the Microwave (Part 1)

Simply after dinner.

Sagawa Yan returned to the study again.

Continue to complete your dissertation.

The purpose of his thesis is to establish a mathematical physical model for the state of the plasma when it breaks.

Then, by analyzing and studying the model, we can gain a deeper understanding of the plasma on a realistic engineering level.

"There are many kinds of plasma."

Sagawa Yan thought mentally.

Plasma actually has a simple and popular name, plasma.

It is the plasma bomb that is often seen in the game, the plasma of the plasma cannon.

Plasma differences between different materials are enormous.

Plasma states like ordinary materials may only require temperatures of a few thousand degrees.

You can even make your own at home.

Nuclear fusion is different.

Nuclear fusion in the sun is bound by gravity.

In the center of the sun, the temperature is as high as 15 million degrees Celsius, and the "870" pressure reaches more than 300 billion atmospheres. Under such high temperature and high pressure conditions, nuclear fusion occurs.

On the blue star, such pressure conditions cannot be achieved, and more temperatures are required.

"I remember that there was a 100 million-degree plasma duration in my previous life."

The pen in Yan Sagawa's hand was twirling in circles between his fingers.

"No wonder fusion is so hard."

However, the difficulty is more challenging.

The corners of Sagawa Yan's mouth turned up, transforming scientific theories into engineering results in his own hands.

It's a great feeling too.

The spinning pen in his hand suddenly stopped, and he started writing on the manuscript paper again.

In the summer night, it is quiet and lively.

The cicadas kept singing, and the husbands who got off work took the whole family out for a walk.

And the stars in the night sky seem to be forever.

These two words are obviously opposite, but they can appear at the same time. This is the charm of Xia Tian.

After taking a shower, Xiaolan changed into short-sleeved pajamas, revealing her white and green arms and slender legs.
