What's the situation???

Doesn't make sense?

Liu Chi scratched his hair, turned back to the server workbench, and carefully checked the lines on the screen again.

Three hours later!

Liu Chi checked a large circle.

The two wind system amplification formations and the high magnetic mud should be no problem.

What's wrong with the bottom? Liu Chi scratched his forehead, leaned directly back on the chair a little helplessly, and thought about it.

Couldn't this device generate a magnetic field?

......

Liu Chi slowly pondered!

Flux, flux?

E-swimming?

According to the electron principle, electrons have spin angular momentum, and the specific value of their spin angular momentum is determined by the spin quantum number of the electron nucleus.

Different types of electron nuclei also have different spin quantum numbers:

An electron nucleus with an even number of masses and protons, and a spin quantum number of 0, i.e., I=0,

An electron nucleus with an odd mass and a semi-integer spin quantum number?

The spin quantum number is not 0, the mass number is even, the proton number is an odd number of electron nuclei, and the spin quantum number is an integer, so that the magnetic nucleus is automatically generated.

A flash of light flashed in Liu Chi's mind, and a spirit sat up straight!

Magnetic resonance signal?

The frequency of the electron-nucleus motion is determined by the strength of the applied magnetic field and the nature of the electron nucleus itself?

Liu Chi's eyes are getting brighter and brighter: that is to say, for a specific electron, in an external magnetic field of a certain intensity, the frequency of the spin precession of its electron nucleus is fixed.

No wonder the moving magnetic field is not detectable.

'......Smack' Liu Chi slapped his thigh excitedly.

So that's the problem.

Now the problem has been found, but how should it be solved?

How to get the electron nucleus to move, that's the key.

According to the principle of electromechanics, the angle between the electron nuclear magnetic moment and the applied magnetic field is not continuously distributed, but is determined by the magnetic quantum number of the electron nucleus.

The direction of the electron's nuclear magnetic moment can only jump between these magnetic quantum numbers, and cannot change smoothly, thus forming a series of energy levels.

When the electron nucleus receives energy input from other sources in the applied magnetic field, an energy level transition occurs, that is, the angle between the electron nuclear magnetic moment and the applied magnetic field changes.

This energy level transition is the basis for obtaining magnetic resonance signals.

......

How can I get it?

If the precession of the electron nucleus is to undergo an energy level transition, it is necessary to provide the electron nucleus with the energy needed for the transition, and this energy must be provided by an external radio frequency field.

Outfield???

According to the principle of physics, when the frequency of the applied RF field is the same as the frequency of the spin precession of the electron nucleus, the energy of the RF field can be effectively absorbed by the electron nucleus, providing assistance for the energy level transition.

Therefore, a particular electron nucleus, in a given applied magnetic field, only absorbs the energy provided by a specific frequency RF field, thus forming a magnetic resonance signal.

However, not all electron nuclei can produce this phenomenon, and electron nuclei can produce NMR phenomena because they have electron spins.

The spin of the electron nucleus produces a magnetic moment, and when the nuclear magnetic moment is in a stationary external magnetic field, a precession nucleus and energy level splitting are generated.

Under the action of an alternating magnetic field, the spin nucleus absorbs electromagnetic waves of a specific frequency and jumps from a lower energy level to a higher energy level to produce a specific school field.

"Hahaha!!" Liu Chi's mouth can be stuffed with two eggs: "I'm such a genius!"

After calming down, Liu Chi touched his chin and thought: It seems that he still needs to load an electromagnetic wave device!

The electromagnetic wave device is very simple.

The work indicator can be used as a starting device.

This path should work, try it first.

Liu Chi immediately sat up straight, opened the 3D CAD, and started to dry directly.

......

Four hours later.

Liu Chi stopped and stared at the computer screen with satisfaction, this time it should be done!

Later, I was thinking about how to combine these devices together to form a whole.

That's it!

This time it's absolutely OK!

Because the theory is perfectly fine.

If the amplification force field is large enough, it can be reversed, and the magic can be changed into a magnetic field dismantling device, and then you can go directly to the sky without lifting.

Levitation......

Hey, hey, hey! Such black technology must be developed!

Forehead!!!

But don't rush now, wait until you get the rice cooker first, you must try it.

How can you do it without trying such a fun thing.

Belch......

Looks like I'm a little hungry!

Liu Chi, who had returned, felt that his stomach had begun to protest, picked up the mobile phone that was put aside, and glanced at the time, it was already more than six o'clock in the afternoon.

Ye Yuxin sent several unread voices.

There's also a missed call!

Get...

Looking back, it was indispensable to bury her, I don't know if she got off work, Liu Chi directly sent a voice call to Ye Yuxin.

"Stupid, you still know how to send me a voice! Don't look at what time it is!" As soon as the voice was connected, Ye Yuxin's 'roar' was ushered in on the mobile phone.

"Uh......"

"I think you're dying in the lab, if you don't come down to eat at noon, you won't come down at night. Ye Yuxin heard that Liu Chi didn't speak, and said a little angrily: "Stupid, have you finished it?" ”

"Almost. ”

"Then don't you get down quickly, I'm in the office. Ye Yuxin said a little annoyed.

“......”

After hanging up the voice, Liu Chi saved some data and made sure that there was no problem, and walked out of the laboratory.

"Give me lab access. Ye Yuxin's first words when they met.

"Huh?" Liu Chi was stunned and said, "I didn't want it for you before, why do you suddenly want it now?"

"I'm afraid you'll starve to death in the lab. Ye Yuxin pretended to have a fierce woman's face: "Stupid, you are not alone now." ”

"I know, I know, the main thing is that today's inspiration exploded, next time I pay attention, and I will give you permission tomorrow, can you. Liu Chi directly used the boy's ultimate move to deal with a temperamental girl, put his arm around Ye Yuxin, and kissed her lightly on the forehead.

"What are you going to do, villain!" Ye Yuxin, who was still preparing to repair Liu Chi again, didn't know anything at this time, and was shy.

"Okay girl, this time it was a sudden inspiration, I must pay attention to it now. Liu Chi let go of Ye Yuxin's hand and said, "Let's go, let's eat." ”

"Hmph..."Ye Yuxin took Liu Chi's hand a little arrogantly and walked out of the office.

......

"Liu Chi, where are we going to eat?" Ye Yuxin habitually got into Liu Chi's special car, closed the door with her backhand, buckled her seat belt, and asked.

"I'll take you to a good place, a Hunan restaurant, I've been there several times, and the dishes there are good. ”

"Okay, but if it doesn't taste good, I'll beat you. ”

"Don't worry, it's all right. ”

Half an hour later.

Times Square.

"Is it here?"

"Yes, let's go... Get out of the car!" Liu Chi unbuckled his seat belt and opened the car door.

"You don't mean the Hunan restaurant on the fifth floor, right?" Ye Yuxin asked, looking at this familiar place.

"Huh, you know?"
