Scholar’s Advanced Technological System

After completing the last step, Wang Xiaodong packed the data and looked at the side of the boat: "The completion of the iterative calculation program in the main deceleration phase, the spatial coordinate position of the near-month and the far-moon point, and the speed direction of the Chang'e-3. , I sent you an email?"

Lu Zhoutou, who is currently calculating, does not lift: "Throw me QQ directly."

Wang Xiaodong: "OK, next step?"

"...the satellite orbit around the moon and the satellite landing orbit geometry, the data parameters are here, the drawing will ask you." Throw the almost full A4 paper brush on Wang Xiaodong's desk, and the boat starts without stopping. The next calculation.

After sweeping the data on the paper, Wang Xiaodong skillfully changed the Matlab software into a more professional SAS software for data drawing, and answered with no expression: "Okay."

The two men cooperated quite well and fought in their respective areas of expertise.

Just at 12 noon, Lin Yuxiang walked lightly into the computer room, placed two yellow chicken rice on the table, and two bottles of canned coffee.

"Study the tyrants, open the meal."

Wang Xiaodong quickly got up and took over his own share. He squeezed a smile from his face: "Thank you."

Lin Yuxiang naturally responded with a smile, then walked to the side of the boat and handed out the plastic bag in his hand: "Hey, yours."

Lu Zhoutou did not lift: "Help me put it on the side, wait for me to finish this step."

"okay!"

At nine o'clock in the evening, Lin Yuxiang hit Haqi back to the bedroom. When it was more than ten o'clock, Wang Xiaodong also went back. As the main force of tomorrow, he must sleep enough today.

At this point, there are only a few people left in the computer room besides Lu Zhou.

Including a number of second class Luo Rundong, including Liu Rui their team's thigh.

Liu Rui is naturally a kid, and he is also a junior in the statistics department next to him.

Their team configuration is a bit special, the captain responsible for programming is the captain, and is responsible for part of the modeling work, but does not involve calculations, mainly to assign tasks to the main modeling of Liu Rui, while directing another person to start writing the outline of the paper .

The statistical tyrant being programmed suddenly said coldly: "Is that buddy your bedroom?"

Liu Rui squatted and nodded: "Yes."

Xueba said casually: "The buddies are very powerful. When I went out to the toilet, I looked at them. They chose A. The competitors should be much less than us."

Liu Rui strangely asked: "So why don't we choose A?"

After counting it for a long time, the hair on his head was almost gone, and I didn't feel the simplicity of the B question at all.

Xueba is unceremonious: "Because I took you this year, do you think I want to choose the B question?"

Liu Rui: "..."

Another little friend who has no nonsense from beginning to end: "..."

At three in the morning, there were only five people left in the computer room.

At four o'clock in the morning, sitting in front of the computer, only one of the Lu Zhou.

When the sky outside the window glowed with the light of the early morning, Lu Zhou finally wrote the last line of calculations.

The door of the engine room was pushed open and Wang Xiaodong came in.

"nailed it?"

“Getting it...” Lu Zhou took a sigh of relief. “Basic modeling has been completed. The rest is programming, drawing, and sensitivity analysis by observing changes in the simulation results. When you are done, I start writing. The second half of the paper."

Wang Xiaodong nodded: "Give it to me, let's go to rest."

"Ok."

Lu Zhou pinched his eyebrows, shook his head, stood up and walked outside the machine room.

This level is nothing compared to the days and nights in the summer vacation.

Specifically, how to return to the bedroom, Lu Zhou has not remembered clearly, just remember to open the door, even the clothes do not take off, kneeling on the bed and falling asleep.

And when he woke up, the window was already dusk.

Sitting up from the bed, Lu Zhou licked the messy hair, touched the phone out of his pocket, and watched the time.

When I remember the bedroom, I remember it at six o'clock in the morning.

"I have slept for twelve hours..."

The next time you sleep, you have to wait for the game to end.

Go to the bathroom to wash clean, Lu Zhou went directly to the machine room.

When he arrived at the engine room, Wang Xiaodong just finished the last program.

Lin Yuxiang is not there, but he helped him buy the rice, and even touched it, it should be brought soon.

Lu Zhou untied the plastic bag and was about to open the bag of the chopsticks. He found that the bag was open and stuffed with a piece of paper.

Slightly squatted, took it out and unfolded.

[To refuel~O(∩_∩)O]

Lu Zhou: "..."

The paper was smashed into a ball, and Lu Zhou threw it into the plastic bucket in the corner, and opened the disposable chopsticks to start eating.

After three, five and two to solve the dinner, Lu Zhou went to the bathroom and washed his face, and threw the takeaway box to the trash can outside the corridor.

When he came back, Wang Xiaodong pushed his glasses and stood up from the position and looked at him.

"The program I have finished, the code text used by the three questions I have sent you on QQ, I will come back at three in the morning, the paper will ask you."

"OK, remember to set an alarm clock, don't forget."

"Know." Wang Xiaodong nodded and turned and left.

He took the same shot as the relay race, and Lu Zhou sat at the computer desk and stretched out.

It is 7 o'clock in the evening, and there are 37 hours left before the paper is submitted.

In these 37 hours, he needs to integrate all the calculation process, modeling ideas, procedures, and further promotion of the three issues into a 20- to 30-page paper.

No matter how exquisite the model, how ingenious the program design, and finally presented to the judges, will be in the form of papers. If the paper can't be understood by the judges and the judges understand the subtleties, then the prize won't be discussed.

Therefore, this last step must not be sloppy!

Lu Zhou, who entered the working state, completely forgot the time. The attention was highly concentrated on the computer screen. The typing hand was as fast as a broken image, just like his smooth and meticulous thinking.

The abstract at the beginning of the paper, the keywords, are controlled within one page according to the format requirements. After the completion of Lu Zhou, a simple deletion has been made to meet this condition.

No one knows the whole idea of ​​modeling better than himself, so it's so easy to do.

This is followed by the most cumbersome process of argumentation. Here is the dry goods part of the whole paper. Although it does not take up too much space, it is the most time-consuming place to complete.

Because it involves not only the idea of ​​mathematical modeling, but also programming ideas.

The former has a lot in mind, while the latter needs to communicate with the person in charge of programming to complete.

After a minute and a second, the sun that completely fell outside the window rose again, and once again, it slanted to the horizon.

When the night was thorough, Lu Zhou finally completed the last line of the promotion section.

Stretched a lame, Lu Zhou stared at the paper with a sleepy eye, yawning and talking to himself.

"...the next step is the reference and the appendix, and finally it is time to finish."

With both hands on the keyboard, Lu Zhou copied the title of the cited document and posted it.

【

...... Moon soft landing gravity turning track design and analysis (C), Huaguo Aerospace Association deep space exploration technology professional committee second academic conference. 2005.

...... Research on the detection and evasion scheme of manned lunar surface obstacles, Space Return and Remote Sensing. 2014, 35: 11-19

......

】

A total of six Chinese documents and one English document were cited.

In the final step, Lu Zhou copied Wang Xiaodong's code in the appendix at the end of the document.

Standing behind Lu Zhou, Wang Xiaodong pushed the glasses and looked at the words on the screen and asked, "Is it done?"

"Well, they are all done. You can check and check the typo for me. If there is no problem, turn it into a pdf format." Standing up from the stool, Lu Zhou shook his groggy brain. "I have to go back to sleep." , the MD5 code and the upload work are handed over to you."

"You are going," paused for a moment. Wang Xiaodong said a few words of concern to the people. "Be careful on the road, don't fall."

"Yeah." Lu Zhou nodded and walked outside the computer room.
