Chapter 100 Partial Differential Equation

"Brother Feng, did you say that on purpose just now?"

When she arrived at the teaching building, Han Feng and Liu Yueshuang were about to separate, she asked.

Han Feng smiled and said, "Haha, you are smart! That Robert is not a good bird. If he really had an intention to you, I would definitely not agree."

Liu Yueshuang said seriously: "I won't like other people anymore!" After that, she ran away.

Han Feng looked at her back as she was leaving and sighed: "Silly girl!"

In Han Feng's opinion, Liu Yueshuang's feelings for her should be largely grateful, not a true relationship between men and women. As time goes by, she will gradually realize this. And he has indeed regarded her as his sister over the years.

Shaking his head gently, Han Feng walked into the classroom.

Professor Li Zhongwen was already waiting on the podium for the bell for class. When he looked up and saw Han Feng coming in, he nodded at him with a smile. Han Feng hurriedly greeted him.

Professor Li Zhongwen's class is still so easy to understand and easy to understand, and can successfully attract students' attention and affect their emotions.

Intentionally or unintentionally, Li Zhongwen would occasionally mention some of the latest research results at the forefront of the world. Although it was just a few words, it could broaden the horizons of the Korean style, point out the direction, bring thoughts and inspiration to his study and research.

The two classes passed without realizing it. For such wonderful courses, I often feel that time passes quickly, and all students have the same feeling.

Professor Li Zhongwen packed up the lesson plan, then nodded slightly to Han Feng, signaling Han Feng to leave with him.

There was no conversation between them for a while. Han Feng was about to find out how Li Zhongwen's research was going, so he immediately followed Li Zhongwen's footsteps and chased after him.

"Shanshan, Han Feng seems to be very familiar with your father. I guess Han Feng must have another problem and asked Teacher Li privately." Liu Ya said to Li Shanshan, her eyes still stayed at the door, and Han Feng's back had just disappeared from there.

"Oh? Why do you think so?" Li Shanshan asked.

"I saw that he and Teacher Li often chatted together, and they seemed to be very speculative."

The small lake in the school, which is small in size, is called Couples Lake because the lake is the favorite place for couples to go to at night.

Li Shanshan was a little surprised. She didn't know about this situation.

"often?"

"Yes, I've seen it twice."

Li Shanshan asked in confusion: "How could you see it? Could it be that you..."

When Liu Ya heard Li Shanshan's words, her face suddenly turned red. After a long time of silence, she suddenly said, "Shanshan, I found that I fell in love with Han Feng. What should I do if you say I should do!"

Li Shanshan smiled and said, "No way?"

"I mean it!" Liu Ya no longer cared about being shy. She suddenly put her mouth in Li Shanshan's ear in a very gossip and said in a low voice, "I tell you, Han Feng is the prince charming in the eyes of many girls in the class, and many girls are secretly in love with him!"

"Uh... it's not that exaggerating, right?" Li Shanshan's face was a little unnatural.

Liu Ya said: "How is it impossible! Han Feng is so outstanding, he is simply a perfect boy! It is very normal for everyone to like him."

Immediately afterwards, Liu Ya told Li Shanshan everything Han Feng did after coming to school, including playing basketball, playing with others on behalf of the computer club... Nothing happened! Even she knew Han Feng's residence outside. If Han Feng was by his side now, she would definitely think that Liu Ya had hired a private detective to investigate her.

Li Shanshan has even heard of many things. I really don’t know where Liu Ya found out, and she even said it vividly and vividly.

"I tell you that many girls in the class have secretly handed love letters to Han Feng."

"Ah?" Li Shanshan called in a low voice.

"Shanshan, why are you so surprised?" Liu Ya said strangely, "It's normal for such a thing to do. Such a good boy and so many people rob him, so you naturally have to take the initiative."

What she said seemed to make sense. Li Shanshan nodded thoughtfully, but sighed in her heart, how could you win over nancy?

At this moment, Li Shanshan suddenly remembered something and smiled and said, "Yaya, have you ever secretly sent him a love letter?"

Liu Ya's face turned red again: "Not yet."

"Why? Didn't you just say you should take the initiative?"

"I'm scared. The love letters of the girls in front end were finally in the trash can. Han Feng looked cold all day long, and no one could get close to him. You said I was just sending love letters like this, and my final fate must be the same as them, so I'm not that stupid!"

...

Han Feng followed Professor Li Zhongwen to the laboratory of the Department of Neuroscience.

"Han Feng, I can now be sure of the correctness of this theory." Professor Li Zhongwen said, "During this period, I have done a lot of experiments, all of which are conducted on the lonely wave conjecture. Although due to the limitations of conditions, I have not been able to positively prove that the nerve pulses propagate in the body in the form of lonely waves, but indirect experimental measurement methods show that the nerve pulse is indeed a mechanical pulse!"

Professor Li Zhongwen took out a stack of experimental data and handed it to Han Feng. These data were all the experimental measurement results he had been doing during this period.

These days, under limited conditions, he has made extremely precise detection of nerve pulses from electricity, sound, magnetism, light and temperature based on his conjecture, thus drawing the current conclusion. He measured the electrical conduction impedance characteristics of the nerve membrane medium before and after nerve pulse conduction, the transmission characteristics of ultra-low frequency vibration waves, the magnetic flux changes under the low-temperature superconducting quantum interferometer, temperature changes, and glow discharge phenomena under high voltage and high-frequency electromagnetic fields.

"Of course, these experimental data were measured from animals. I have not measured the human body yet, but this is not the key. In this regard, humans and animals are completely consistent." Li Zhongwen continued.

Han Feng carefully read these experimental data. To be honest, some of them were too professional and he couldn't understand them, but he still understood most of them. After all, he has not been in vain during this period.

Han Feng had actually completely accepted Li Zhongwen's conjecture in his heart, because many of the data were gentle with his usual observations, and using his conjecture could perfectly explain these phenomena.

But science is rigorous. To turn it into a real theory, in addition to experimental data, there must also be strong evidence. For example, the lonely wave phenomenon (translation wave) discovered by Russell from the water flow ten years after his death, Dutch mathematicians Cotweg (d.j.kortweg) and Devries (c.de vries) mathematically proved the existence of "Russell wave". They came up with a nonlinear equation called "kdv equation". The solution to this equation happens to be Russell's lonely wave.

The current test equipment and instruments in China are not enough to accurately measure the extremely subtle data of nerve pulses. The data he obtains now are rough and fuzzy, and obviously has no further research value.

However, Han Feng can help in this regard. When it comes to microscopic, I believe that even the most precise instruments in the world cannot compare to Han Feng's "internal vision" function.

Professor Li Zhongwen's theory can be said to have brought great inspiration to Han Feng, which made him gradually understand his body from a scientific perspective, and it is likely that he would even uncover the mystery of Danliu and internal force. Therefore, Han Feng decided to help Professor Li Zhongwen, which can also be regarded as making some contribution to the country. If Professor Li Zhongwen went abroad because the experimental instruments could not meet the requirements, and the theory was born abroad by then, it would be a bit unfair.

So, after returning to his residence, Han Feng temporarily put aside the super system's organization and began to observe the conduction of nerve pulses from Professor Li Zhongwen's perspective.

As Professor Li Zhongwen said, at the moment when nerve pulses are transmitted, the medium in the nerve membrane will change from liquid to a strange solid, and this is a chemical change, that is, the components before and after the nerve membrane have changed, but this chemical change occurs in a very short time. If Han Feng had not observed it carefully in a targeted manner, it would have been impossible to discover it.

Han Feng's method of recording these data is very simple. He wrote a simple neural pulse intensity detection mini program, targeting a specific neural pulse, and then intercepting the changes in the intensity of nerve pulses before and after a certain segment of nerve fiber, the time used, and other parameters. Then he saved these parameters to his brain disk in a fixed format.

This is a boring and monotonous process, so after Han Feng designated a few special observation points, he no longer paid attention to it, but began to analyze the recorded data.
