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.
Two wind amplification arrays to heighten the magnetic mud should be no problem.
What went wrong? Liu Chi scratched his forehead, leaned on the chair helplessly, and started thinking.
Couldn't this device produce a magnetic field?
...
Liu Chi slowly began to think deeply!
Magnetic flux, electric flux, magnetism?
Electronic swimming?
According to the electronic 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 have different spin quantum numbers:
The electron nucleus with an even number of mass numbers and protons has a spin quantum number of 0, that is, i=0,
An electron nucleus with an odd mass number has a half-integer spin quantum number?
Its spin quantum number is not 0, its mass number is an even number, the number of protons is an odd number, and its spin quantum number is an integer. This automatically generates a magnetic nucleus.
A flash of light flashed in Liu Chi's mind, and he sat up straight with excitement!
Magnetic resonance signal?
The frequency of electron nucleus motion is determined by the strength of the external magnetic field and the properties of the electron nucleus itself?
Liu Chi's eyes became brighter and brighter: that is to say, for a certain electron, in an external magnetic field of a certain strength, the frequency of its electron nuclear spin precession is fixed.
No wonder the moving magnetic field cannot be detected.
‘Pah…’ Liu Chi slapped his thigh excitedly.
It turns out that this is the problem.
Now the problem is found, but how to solve it?
How to make the electron nucleus move is the key.
According to the principles of electronic mechanics, the angle between the magnetic moment of the electron nucleus and the external 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, but cannot change smoothly, thus forming a series of energy levels.
When the electron nucleus receives energy input from other sources in an external magnetic field, an energy level transition will occur, that is, the angle between the magnetic moment of the electron nucleus and the external magnetic field will change.
This energy level transition is the basis for obtaining magnetic resonance signals.
...
How can I get it?
If the precession of the spin of the electron nucleus causes an energy level transition, the electron nucleus needs to be provided with the energy required for the transition, and this energy must be provided by an external radio frequency field.
Outfield???
According to the principles of physics, when the frequency of the external radio frequency field is the same as the frequency of the spin precession of the electron nucleus, the energy of the radio frequency field can be effectively absorbed by the electron nucleus, providing assistance for energy level transitions.
Therefore, a specific electron nucleus, in a given external magnetic field, only absorbs the energy provided by a radio frequency field of a specific frequency, thus forming a magnetic resonance signal.
However, not all electron nuclei can produce this phenomenon. Electronic nuclei can produce nuclear magnetic resonance phenomena because they have electron spin.
The electron nuclear spin produces a magnetic moment, and when the nuclear magnetic moment is in a stationary external magnetic field, precession nuclei and energy level splitting occur.
Under the action of an alternating magnetic field, the spin core will absorb electromagnetic waves of a specific frequency and transition from a lower energy level to a higher energy level to produce a specific school field.
"Hahaha!!!" Liu Chi could fit two eggs into his mouth: "I'm such a genius!"
After calming down, Liu Chi touched his chin and thought: It seems that he needs to load an electromagnetic wave device!
The electromagnetic wave device is very simple.
You can directly use the work indicator light as a hair device.
This route should work, give it a try first.
Liu Chi immediately sat up straight, opened the 3D CAD, and started working directly.
...
Four hours later.
Liu Chi stopped and stared at the computer screen with satisfaction. It should be done this time!
The next step is to think about how to combine these devices to form a whole.
That’s it!
It’s definitely ok this time!
Because the theory is absolutely fine.
If the amplifying force field is large enough, it can be completely reversed and transformed into a magnetic field detachment device. Then, it can go directly to the sky without any lift.
Levitation...
Hey hey hey! Such black technology must be developed!
Forehead!!!
But don’t rush now, I will definitely give it a try after I finish using the rice cooker first.
How can I not try such a fun thing?
Well......
I seem a little hungry!
After Liu Chi came back, he felt that his stomach had begun to protest. He picked up the mobile phone placed aside and glanced at the time. It was already past six o'clock in the afternoon.
Ye Yuxin sent several unread voice messages.
There is also one missed call!
have to...
After looking back, it was inevitable to have a meal. I didn't know if she had got off work, so Liu Chi directly sent a voice call to Ye Yuxin.
"Idiot, you still know how to send me a voice message! You don't even know what time it is!" As soon as the voice call was connected, Ye Yuxin's 'roar' came to the phone.
"Well......"
"I think you died in the laboratory. If you don't come down to eat at noon, you won't come down at night either." When Ye Yuxin heard that Liu Chi didn't speak, she got a little angry and said, "Idiot, have you finished it yet?"
"almost."
"Why don't you come down quickly? I'm in the office." Ye Yuxin said a little annoyed.
"..."
After hanging up the voice call, Liu Chi saved some information and data, and after making sure there was no problem, he walked out of the laboratory.
"Give me access to the laboratory." Ye Yuxin's first words when they met.
"Ah?" Liu Chi was stunned and said, "I didn't want it for you before, why do you want it all of a sudden now?"
"I'm afraid you'll starve to death in the laboratory." Ye Yuxin pretended to be a fierce woman: "Idiot, you are no longer alone."
"I know, I know, it's mainly because I had a big burst of inspiration today. Pay attention next time. I'll give you permission tomorrow, okay?" Liu Chi directly used the ultimate trick for boys to deal with girls with tempers. He hugged Ye Yuxin and faced her.
A gentle kiss on the forehead.
"Bastard, what are you going to do!" Ye Yuxin, who was originally preparing to repair Liu Chi again, didn't know anything at this time and was too shy.
"Okay girl, this time I suddenly had inspiration, I must pay attention now." Liu Chi released his arms around Ye Yuxin and said, "Let's go, let's go eat."
"Hmph..." Ye Yuxin held 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 car, closed the door behind her back and buckled her seat belt, and asked.
"Let me take you to a good place, a Hunan restaurant. I've been there several times. The food there is pretty good."
"Okay, but if it doesn't taste good I'm going to beat you up."
"Don't worry, it's absolutely fine."
Half an hour later.
Times Square.
"Here?"
"Yes, let's get out of the car!" Liu Chi unbuckled his seat belt and opened the door.
"You're not talking about the Hunan restaurant on the fifth floor, are you?" Ye Yuxin asked, looking at this familiar place.
