Because of the pursuit of typing speed, the sound of tapping on the keyboard is a bit loud, but fortunately his roommate didn't trouble him because of this.

After half an hour, dense characters appeared on the computer screen, which were all part of the experimental protocol.

Typing on the computer lasted for half an hour, and even with Shang Yiyun's physical fitness, there was a slight discomfort.

In this case, he could only get up from his chair, stretch, and then walked out of the dormitory door, watching things in the distance in front of the dormitory door.

I had been staring at the computer screen before, which caused some discomfort in my eyes, so Shang Yiyun came to the outside of the dormitory to see some green plants downstairs in the dormitory.

After watching it for a while, he went back to his dorm room and continued to write the protocol.

Since he wants to complete the experimental plan today, although he wants to finish it as soon as possible, instead of waiting until he is about to take a break, he has completed 50% of the content, as long as he finishes the remaining 50%, his task will be completed.

Thinking of this, Shang Yiyun sped up the speed of typing, and it was like a storm, and characters kept appearing on the computer screen.

When typing, he focuses on it, and some subtle changes in the outside world do not affect him, and it is precisely because of this concentration that he has a relatively high typing speed.

Soon a document of several thousand words was completed, and the whole process took 50 minutes, and if it wasn't for the thinking about some problems while typing, the completion of the experimental protocol would have been faster.

But now that the protocol has been completed, the process doesn't matter.

Seeing that it was already six o'clock in the evening, he could go to the cafeteria for dinner in another hour, and he was never absent from eating.

Enjoying food is also one of his hobbies, and it is one of his dreams to travel all over the country and enjoy food from all over the country.

But now there are more things, and research can't be delayed, so this dream can only be a dream, maybe when he has free time in the future, he can take Chen Feiyun to travel all over the country.

Of course, these things cannot be realized at present, but he believes in his heart that he can definitely realize this dream in the future.

The world is so big, I want to see it. This sentence has become a hot search topic on the Internet, and it is also a good way to relax your mood by going out for a walk when you are young and seeing the great rivers and mountains of the motherland.

It's too early to think about these things, and while there is still some time before going to the cafeteria for dinner, Shang Yiyun takes a look at the real-time news in the world.

He is not the kind of person who does not listen to the outside world and only reads the books of the sages, but he pays close attention to some domestic and international news, because from these news, you can get useful things.

For example, which country has developed the latest drug, and which country has made a breakthrough in aerospace technology, from these news, plus some news heard in the previous life, Shangyi Yun can make a simple prediction of the country's scientific and technological development.

An hour is not long, and soon it will be seven o'clock in the evening, and it will be time to go to the cafeteria for dinner.

Thinking of this, Shang Yiyun turned off the computer and left the dormitory to prepare to go to the school cafeteria.

Walking on the way to the school cafeteria, I saw many couples eating full of dog food.

For this situation, but it is also more helpless, Chen Feiyun is at Huaguo Normal University, otherwise, the two of them will hold hands and go to dinner together, which is better than being alone now, but he can only think about it.

Although the distance between the two schools is not too far, Shang Yiyun will not interfere in each other's lives, and everyone must have their own private space, rather than being manipulated by others all the time like a marionette.

While he was thinking, he had come to the school cafeteria unconsciously, walked directly into the cafeteria, made a meal, and found a place to sit down.

But he didn't expect to meet an acquaintance at this time, this person is Qin Liyue, Shang Yiyun hasn't seen each other for a long time, he didn't expect to meet each other today.

Qin Liyue also found out where Shang Yiyun was, so she took the dinner plate and went to the opposite side of Shang Yiyun.

"Senior Brother Shang Yiyun, I didn't expect to be able to meet you here, it seems that we are very fateful!"

At this time, Shang Yiyun heard Qin Liyue's words, and knew that he couldn't hide, so he said helplessly.

"Yes, I didn't expect to meet you in the school cafeteria, I heard you say before that you are going to study in Millican next semester, I don't know if you are ready?"

Now that Qin Liyue was already sitting opposite him, Shang Yiyun naturally didn't pretend not to know each other, but found a topic and prepared to talk about it.

At this time, Qin Liyue was still quite happy when she heard this question, she could feel that Shang Yiyun always had a feeling of alienation from her, although she didn't know why this situation happened, but she still hoped to chat with Shang Yiyun in her heart.

She didn't know that it was her joke that caused the current situation, mainly because her expression at that time was too real, like a Frankenstein who is desperate for research.

Shang Yiyun was the first to speak, which also exempted her from embarrassment, thinking of this, Qin Liyue had a smile on her face.

"Well, I am indeed going to Millican for a PhD next semester, and I have prepared everything I need to prepare, and I will stay at Kyoto University for more than a month, and when the next semester begins, I will go to Millican. ”

Hearing Qin Liyue's explanation, Shang Yiyun also felt a trace of parting sadness in his heart, after all, he had been in a team for nearly a month, if it wasn't for Qin Liyue's words that scared him, maybe the relationship between the two would not be what it is now.

No matter what, they won't see each other again next semester, and Shang Yiyun was inexplicably relieved.

"Since Senior Sister is going to Milican to study for a doctorate, then I am here to wish you that you can achieve your goals. ”

After saying these words, the two chatted about some innocuous things again, and seeing that the plate in front of them was empty, Shang Yiyun proposed to say goodbye.

It's already half past seven in the evening, and after coming out of the school cafeteria, I'm ready to go for a stroll near Weiming Lake.

After walking around, he prepared to leave the place, and then went back to the dormitory, and stayed near Weiming Lake for an hour, the sky became darker, and it was time to leave.

When he returned to the dormitory, he took a book out of the bookshelf and began to read it carefully, and it became a habit to read books every night, even if he gained little knowledge from these books, he still persisted.

Time slipped away slowly in the process of reading books, and in a blink of an eye, it was half past nine in the evening, which was close to the usual rest time.

Putting the books back on the shelves, Shang Yiyun took a set of clothes from outside, and then went into the bathroom, ready to take a hot shower.

After taking a hot shower and changing into a set of clean clothes, Shang Yiyun climbed into bed and began to close his eyes to rest.

Of course, it's not even ten o'clock yet, and closing your eyes is naturally not resting, but thinking about some questions.

I met Qin Liyue today and chatted with the other party for a while, Shang Yiyun felt a little emotional, no matter what, he still recognized the other party's ability, and next semester, the other party will go to Milican to study for a doctorate.

At this time, Shang Yiyun knew in his heart that his knowledge level had reached the doctorate level, and whether it was the level of knowledge and ability or the level of practical operation, he could be compared with those doctors, or even higher.

In the heart of Shangyiyun, the most important thing is to have research results in the field of scientific research, and the results are more important than the process.

After thinking about it for a while, Shang Yiyun felt that his eyelids were getting heavier and heavier, and he slowly entered his dream.

He did a lot of things today and consumed a lot of energy, so he will quickly go into a state of rest.

Early the next morning, after resting for a night, Shang Yiyun felt that he was full of energy, and he seemed to have inexhaustible strength in his body.

Get dressed and get out of bed, wash and brush your teeth, and start your day.

But he found that it was raining outside, and the raindrops were connected into a line, visible to the naked eye, and in the face of this situation, after washing, he called Chen Feiyun and canceled the plan for the two to exercise together.

This kind of weather can't stop normal classes, two classes in the morning and four classes in the afternoon, which is today's class arrangement.

Of course, there were still two hours before class, and in this weather, he didn't think about going to the classroom in advance, but sat on a chair and waited.

At this time, his roommate had not gotten up yet, and the dormitory seemed very quiet, as for Shang Yiyun, he took out the computer, first copied the experimental protocol file he wrote yesterday to the USB flash drive, and then searched for information on the computer.

There is a huge amount of information on the Internet, and it is not difficult to select useful content from such a large amount of information, because there is such a thing as a search engine on the Internet.

After searching like this for a few minutes, Shang Yiyun finally found what he wanted, opened the file and started watching.

Staring at a computer screen is naturally not as comfortable as reading with a book, but under such conditions, you can only watch it.

After watching it for a while, Shangyi Cloud also learned some new knowledge.

Nuclear energy, or atomic energy, is the energy released from the nucleus of an atom through a nuclear reaction, in accordance with Albert Einstein's mass-energy equation E=mc2, where E = energy, m = mass, and c = speed of light.

Nuclear energy can be released through one of three nuclear reactions: one is nuclear fission, in which the heavier nuclei split to release nodule energy. The second is nuclear fusion, in which lighter nuclei fuse together to release nodule energy. The third is nuclear decay, in which energy is released during the spontaneous decay of atomic nuclei.

Nuclear energy is one of the most promising sources of energy for the future. There are two ways to develop nuclear energy: one is the fission of heavy elements, such as uranium, and the other is the fusion of light elements, such as deuterium, tritium, lithium, etc.

The fission technology of heavy elements has been applied in practice, and the fusion technology of light elements is also being actively studied. However, whether it is the heavy element uranium, or the light elements deuterium and tritium, there are quite huge reserves in the ocean.

Nuclear energy is a new energy source, Shang Yiyun is now conducting research on new energy, although there is no research on the conditions for nuclear energy, but it does not prevent him from learning more.

Uranium is currently the most important nuclear fuel, and 1 kilogram of uranium can be used for energy equivalent to burning 2,500 tons of high-quality coal.

However, uranium reserves on land are not abundant, but in the ocean, there are abundant uranium resources, and it is estimated that the amount of uranium dissolved in seawater can reach 4.5 billion tons, which is equivalent to thousands of times the total reserves on land.

If all the uranium in seawater can be extracted, the fission energy contained in it can ensure the energy needs of mankind for tens of thousands of years, but the concentration of uranium in seawater is very low, and 1,000 tons of seawater contain only 3 grams of uranium.

It can only be applied if uranium is extracted from seawater first, and to extract uranium from seawater, it is technically very difficult, requiring the treatment of large amounts of seawater, and the technical process is also very complex.

At present, the most widely used is nuclear power generation, and the use of nuclear energy to generate electricity has many advantages.

Unlike fossil fuel power generation, nuclear power generation emits huge amounts of pollutants into the atmosphere, so nuclear power generation does not cause air pollution, so nuclear power generation does not produce carbon dioxide, which aggravates the global warming effect.

Moreover, the energy density of nuclear fuel is millions of times higher than that of fossil fuels, so the fuel used in nuclear power plants is small in size, and it is easy to transport and store, a 1,000 megawatt nuclear power plant only needs 30 metric tons of uranium fuel a year, and a flight can complete the transportation.

The cost of nuclear power generation is less stable than that of other power generation methods, as the cost of nuclear power generation is less susceptible to the impact of international economic conditions.

Of course, there are advantages, and naturally there are disadvantages.

Nuclear power plants produce high- and low-order radioactive waste, or used nuclear fuel, which may not take up much volume, but because of the radiation they contain, they must be handled carefully and face considerable political problems.

Nuclear power plants are less thermally efficient and therefore emit more waste heat into the environment than fossil fuel power plants, resulting in more thermal pollution.

He had watched some knowledge related to nuclear physics before, but what he had seen before was different from what he was watching now.

"Yi Yun, it's already seven forty o'clock, it's time to go to the classroom. ”

At this time, Shang Yiyun suddenly heard Shen Fengyu's voice, looked at the time, and found that more than an hour had passed.

Since it was time for class, he turned off his computer, found a book from the shelf, and followed his roommate to the classroom.

However, on the way to the classroom, he kept thinking about what he had just seen, and he was very interested in nuclear energy, but he also knew in his heart that this kind of thing was not something he could touch now.

Nuclear resources are strategic and not at all something he has access to now.

Perhaps, in the future, if you engage in research in related fields, you can conduct research on nuclear technology in the laboratories established by the state.
