5 a.m.

It was still as dark as ink outside the computer room, and there were still fierce battles in the computer room.

"The inscription is a ......"

Thinking of this, Chen Zhou wrote on scratch paper:

[Suppose the planet has a retrograde outer orbit and has a significant mass, with a mass ratio of 1:10:20 between the planet and the two stars.] 】

[Although the gravitational field is more complex, the orbit is much more complex, but the orbit will still be a stable ......]

He is solving the problem of complex peripheral orbits.

And Yang Yiyi is also solving the problem of small peripheral tracks.

The minutes just ticked by.

At 7 o'clock in the morning, Fang Jieming woke up, turned his head and glanced at Chen Zhou and Yang Yiyi, who were still concentrating on solving the problem in front of the computer desk.

He got up quietly, went to wash up, and then bought breakfast and came back.

He gently patted his two teammates on the shoulders and handed him breakfast.

Chen Zhou and Yang Yiyi's movements were surprisingly consistent, so they took it and put it aside, and continued their work.

Fang Jieming glanced at the two of them, didn't speak, walked to the side and sat down.

Thinking about the division of labor in the team, he couldn't help but wonder, what is the situation? How can the theoretical analysis not be completed in one night?

Then he got up again, walked behind the two of them, and stretched out his head to take a look.

Chen Zhou's scratch paper is densely packed with formulas and calculations.

Yang Yiyi's scratch paper is also dense, but there are not only formulas and calculations, but also the theoretical knowledge she has recorded.

Fang Jieming saw the scratch paper of the two of them, and instantly understood that this was the little couple working together to solve the problem.

He silently returned to his seat, opened the programming software, and made preparations.

About another hour later, Yang Yiyi solved the problem of the small peripheral track.

She stopped her pen and stretched, this night, she was really tired.

glanced at Chen Zhou, who was still continuing, didn't disturb him, got up and went to wash up briefly, and came back to eat breakfast.

Just as she was about to sort out these calculations, Chen Zhou raised her head and said softly, "Let me come, you go sleep for a while." ”

Seeing that Yang Yiyi was a little hesitant, Chen Zhou explained: "I need a complete process to write a thesis later. So, let me sort it out. ”

Yang Yiyi nodded slightly, sorted out the scratch paper, put it next to Chen Zhou, instructed to eat the meal first, and then lay down on the computer desk and began to rest.

Chen Zhou answered, but he didn't stop writing, he had already calculated the last part of the internal track.

【...... When a planet is close to one of the stars and far away from the other, the planet's gravitational field is not much different from that of a separate star system......]

[The period of a planet's orbit around its star is equal to 0.042 times the period of the two stars orbiting each other.] The distance between the planet and the star it orbits is equal to half the distance of the binary star. 】

[If you get closer to another star, the distance between the planet and the star it orbits is equal to 0.67 times the distance of the binary star.] You'll get something very interesting......]

Chen Zhou thought about it, let Fang Jieming use the programming model to do this thing, it is too time-consuming to draw tracks.

According to this line of thinking, Chen Zhou thought of all possible situations, and then used the relevant physical formulas to substitute them, which is the calculation problem.

【...... It is also possible for two stellar peers to form a regular triangle between them, which, as demonstrated by Lagrange in the "Three-Body Problem", will always remain in the same position of the regular triangle as the Trojan group relates to Jupiter and the Sun......]

Around 9 a.m.

Chen Zhou stopped writing, went to wash his face, and used cold water to keep himself awake.

After a simple two-bite breakfast that was already cold, I began to sort out all the theoretical calculation formulas.

Of course, the collection of wrong questions was also brought over by Chen Zhou, and while he was eating, he had already flipped through it.

Based on the mistakes recorded on the problem set, he has corrected it.

Most of them can be guaranteed to be correct, but some contents still need to be tested by the model before Chen Zhou can make final modifications and improvements.

After sorting out the content of the theoretical calculations, some of them were packaged and sent to Fang Jieming through the computer, and some of them were thrown directly to him on scratch paper.

Chen Zhou started the preliminary writing of the paper again, and he has no plans to rest for the time being.

Fang Jieming glanced at Chen Zhou and reminded, "You should rest for a while." ”

Chen Zhou shook his head: "I'm in okay state now, let's build the framework of the paper first, and it will save some trouble in the future." ”

Fang Jieming didn't say much anymore and started his own work.

He's in great shape and it's time to show what he's doing.

Because Chen Zhou participated in the theoretical part of the work in the early stage, it will be much easier to write the paper than those who write papers in other teams.

It just so happened that Fang Jieming's thinking was also completely opened, and he could communicate directly with Fang Jieming about the content of programming in the paper.

When Yang Yiyi woke up slowly, Chen Zhou had almost completed the preliminary thesis work.

Yang Yiyi looked at Chen Zhou, and then looked at the computer screen in front of Chen Zhou, and couldn't help but feel a little distressed.

After Chen Zhou kept the documents, he turned his head and said to Yang Yiyi with a smile: "Let's go, let's have lunch." ”

When passing by Fang Jieming, Chen Zhou asked, "Or Coke?"

Fang Jieming's hand movements did not stop, and he nodded lightly.

In the afternoon, Chen Zhou no longer stayed up, and rested on the table with Yang Yiyi, they had to recuperate.

After Fang Jieming finished programming, they had to refine the theoretical part according to the model.

When Chen Zhou slowly woke up, what caught his eye was that Yang Yiyi was holding a pen and writing something on scratch paper.

Noticing Chen Zhou sitting up, Yang Yiyi smiled at him: "Are you awake?"

Chen Zhou has always felt that Yang Yiyi's smile is the most beautiful, but this kind of experience that can be seen just after waking up is the first time.

"This feeling is so good, if it's not a competition, it's even better......" Chen Zhou thought as he looked at Yang Yiyi.

"Why are you looking at me like that?" Yang Yiyi asked.

Chen Zhou: "It's good-looking. ”

Yang Yiyi smiled: "Okay, get up and work, the senior's programming has ended." ”

Hearing Yang Yiyi's words, Chen Zhou hurriedly sat up straight and turned his head to look at Fang Jieming.

Fang Jieming was also looking at the two of them, thinking to himself: "The competition is finally over......

Chen Zhou glanced at the time, but he didn't expect it to be more than 6 o'clock in the afternoon.

He asked, "Yiyi, when did you wake up?"

Yang Yiyi replied: "A little earlier than you." ”

"Okay......" Chen Zhou knew that this was a little earlier, and he noticed that Yang Yiyi had already written a lot of things on his scratch paper, all of which were revised content.

Chen Zhou stretched his waist, moved his muscles, adjusted his state, and prepared to work again.

"I've already sent you the content that needs to be modified, you can check it. After a pause, Fang Jieming said again, "The theoretical calculations this time are better than the results we had when we formed a team to train before, especially Chen Zhou, there are almost no errors in the calculation part." ”

"That's good, it saves time. Chen Zhou naturally knew what was going on.

This is the usefulness of the problem set for topic research.
