Chapter 61: Liver burst for 72 hours

After completing the last step, Wang Xiaodong packed the data and looked to the side of Lu Zhou: "The iterative calculation procedure of the main deceleration phase is completed. The spatial coordinate positions of the near and far moon points and the speed direction of Chang'e 3 are obtained. I send you an email? "
舟 Lu Zhou, who was calculating, did not lift his head and said, "Just throw me QQ."
Wang Xiaodong: "OK, next?"
"... A schematic diagram of the satellite's orbit around the moon and the geometry of the satellite's landing orbit. The data parameters are here, and the drawing is up to you." Throwing almost the A4 paper brush on Wang Xiaodong's table, Lu Zhou started non-stop The next calculation.
Glancing at the data on his eyelids, Wang Xiaodong skillfully replaced the software with SAS software, which is more professional in data mapping, and answered blankly, "OK."
The two cooperate very well, fighting in their respective areas of expertise.
At exactly 12 o'clock noon, Lin Yuxiang walked into the machine room lightly, put two copies of Huangyao chicken rice on the table, and two bottles of canned coffee.
"Students, let's have dinner."
晓 Wang Xiaodong got up quickly, took over his share, extruded a smile from his face, "Thank you."
Yu Lin Yuxiang naturally responded with a smile, then walked to the side of Lu Zhou, handed out the plastic bag in his hand: "Hey, yours."
Lu Zhou didn't look up: "Let me aside, wait for me to finish this step."
"okay!"
At nine o'clock in the evening, Lin Yuxiang returned to the bedroom with Hatch. At 10 o'clock, Wang Xiaodong went back. As the main force of tomorrow, he must sleep well today.
At this point, except for the boat, there are only a few people left in the machine room.
Including Luo Rundong, the second school tyrant in the class, including Liu Rui's thigh.
瑞 The boy Liu Rui is naturally there, as well as the junior junior of the statistics department next to him.
The configuration of their team is a bit special. The thigh responsible for programming is the captain and is responsible for part of the modeling work, but it does not involve calculation. It mainly assigns tasks to Liu Rui, the main modeler, and directs another person to start writing the thesis outline. .
Suddenly, the statistical bully who was programming asked, "Where is your buddy?"
愣 Liu Rui froze and nodded: "Yeah."
Xu Xueba said casually: "That buddy is very powerful. When I went out to the toilet just now I glanced. They chose question A. The competition should be much less than us."
瑞 Liu Rui asked strangely, "Why don't we choose A?"
After thinking about it for so long, the hair on his head was almost gone, and I didn't feel that the question B was simple.
Xu Xueba said rudely: "Because I took you with you this year, do you think I want to choose question B?"
Liu Rui: "..."
Another friend who didn't talk nonsense from beginning to end: "..."
三 At three in the morning, there are only five people left in the computer room.
At four o'clock in the morning, he was still sitting in front of the computer, only Lu Zhou was left.
When the sky outside the window glowed in the early morning light, Lu Zhou finally wrote the last line of calculations.
The door of the computer room opened and Wang Xiaodong came in.
"nailed it?"
"That's it ..." Lu Zhou breathed a sigh of relief. "The basic modeling has been completed, and the rest is programming, graphics, and sensitivity analysis by observing the changes in the simulation results. When you are done, I start writing The second half of the paper. "
晓 Wang Xiaodong nodded: "Leave it to me, you can take a rest."
"Ok."
Lu Zhou squeezed his eyebrows, shook his head, stood up and walked outside the computer room.
This degree is nothing compared to staying up late in the summer vacation.
How did he return to the dormitory? Lu Zhou didn't remember it clearly. He just remembered that he didn't even take off his clothes after he opened the door. He lay down on the bed and fell asleep.
But when he woke up, it was already dusk.
I got up from the bed, Lu Zhou rubbed his messy hair, pulled out his cell phone from his pocket, and looked at the time.
Guixian faintly remembered that when he arrived in the bedroom, it was six o'clock in the morning.
"Did you sleep for twelve hours ..."
The next time I sleep, I have to wait for the game to end.
I went to the bathroom to clean, Lu Zhou went directly to the machine room.
他 When he arrived at the computer room, Wang Xiaodong just finished the last program.
Zhe Lin Yuxiang was not here, but he bought the rice for him, and it even felt a little hot to touch. He should have just brought it around.
Lu Zhou unpacked the plastic bag and was about to tear open the packing bag of chopsticks, and found that the packing bag was open and a note was stuffed inside.
He stunned for a moment and pulled it out.
【Please cheer ~ O (∩_∩) O】
Lu Luzhou: "..."
Knead the note into a ball, and Lu Zhou threw it into the plastic bucket in the corner, and opened the disposable chopsticks to start eating.
Twenty-three, five, and two solved the dinner. Lu Zhou went to the bathroom to wash his face, and threw the takeaway box to the trash bin outside the corridor.
他 When he came back, Wang Xiaodong pushed his glasses, stood up from his position, and looked at him.
"I have completed the procedure. I have posted the code and text of the three questions on your QQ. I will come back at three in the morning and the paper will ask you."
"OK, remember to set an alarm, don't forget."
"I know." Wang Xiaodong nodded and turned away.
I took the bat like a relay race, and Lu Zhou sat at the computer desk and stretched out.
It is seven o'clock in the evening and there are 37 hours left to submit the paper.
In these 37 hours, he needs to integrate all the calculus processes, modeling ideas, procedures, including the further promotion of three issues, into a 20- to 30-page essay.
No matter how exquisite the model or how ingenious the program design, the final presentation on the judges will be in the form of a dissertation. If the paper cannot be understood by the judges and the subtleties are understood by the judges, then there is no way to talk about winning the prize.
So, this last step must not be sloppy!
Lu Zhou, who entered the working state, completely forgot the time, and concentrated his attention on the computer screen. The typing hand was like a burst of afterimages, just like his smooth and meticulous thought.
开头 The abstract and keywords at the beginning of the thesis are controlled within one page according to the format requirements. After Lu Zhou wrote it, it was simply deleted to meet this condition.
No one knows the whole idea of ​​modeling better than himself, so these tasks are very easy to do.
The following is the most tedious argumentation process. Here is the dry goods part of the entire thesis. Although it does not take up much space, it is the most time-consuming place to complete.
Because it involves more than the idea of ​​mathematical modeling, UU reads www.uukanshu. Com also has programming ideas.
The former Lu Zhou knows well, the latter needs to communicate with the person in charge of programming to complete.
The time passed by one minute and one second, the sun completely falling outside the window rose again, and slanted to the sky again.
When the night was complete, Lu Zhou finally completed the last line of the problem promotion section.
Xun stretched his waist, Lu Zhou stared at the paper with eyes that were almost swollen, and yawned to himself.
"... there are references and appendices, and finally it is about to end."
He put his hands on the keyboard, and Lu Zhou copied and posted the titles of the cited documents.
【
…… Design and analysis of the lunar soft landing gravity turning orbit (C), the 2nd Academic Conference of the China National Aerospace Association Professional Committee on Deep Space Exploration Technology. 2005.
... Study on the detection and avoidance plan of the man-made landfall topographical obstacle, Space Return and Remote Sensing. 2014, 35: 11-19
Uh ...
]
A total of six Chinese literatures and one English literature are cited.
Last step, Lu Zhou copied Wang Xiaodong's code in the appendix at the end of the document.
Standing behind Lu Zhou, Wang Xiaodong pushed his glasses and looked at the text on the screen and asked, "Done?"
"Well, it's all done. You can help me check the typo. If there is no problem, please convert to pdf format." Standing up from the stool, Lu Zhou shook his groggy brain, "I'm going back to sleep , The job of generating the MD5 code and uploading is up to you. "
"Hurry up," he paused for a moment, and Wang Xiaodong said a few words of concern about people, "Be careful on the road, don't fall."
"Um." Lu Zhou nodded and walked outside the computer room.
