On September 12th, the competition will go on as scheduled!
"Question A: Chang'e-3 Soft Landing Orbit Design and Control Strategy...Question B: Creative Flat Folding Table?! Holding Grass? What the hell is this year's question?"
At eight o'clock, the bell rang.
"Designing a table... What can be designed about a table? Isn't it just four legs? It's foldable... Let's put a spring behind the stool legs?"
Although many people choose to use their own laptops to answer questions, usually they still bring their computers to the computer room. After all, only the WiFi in the computer room and library can download papers from CNKI for free. If you hope to win this kind of competition through unverified information on Baidu, it is better to burn a stick of incense and wait for the paper to be completed automatically.
(1) Determine the positions of the peri-lunar point and far-lunar point of the landing preparation orbit, as well as the magnitude and direction of the corresponding speed of Chang'e-3.
Both questions are related to physics.
At eight o'clock, the bell rang.
The day before the competition, Lu Zhou and others took the school bus back to the old campus from the new campus and moved into temporary dormitories arranged by the school.
Going beyond the stem information, there are three questions in total:
"Question A: Chang'e-3 Soft Landing Orbit Design and Control Strategy...Question B: Creative Flat Folding Table?! Holding Grass? What the hell is this year's question?"
Lu Zhou shook his head: "Choose question A."
[To analyze the error of the landing orbit control strategy designed in question 2, we must first list as many factors as possible that may cause the error and analyze them...]
The mattresses and pillows are all prepared. You only need to bring a sheet. Those who are not particular about it can even go directly to the private room. After all, although the competition time is 72 hours, the average bedtime for each person may be ten consecutive hours. Less than an hour.
"Hold the grass, boss, don't you have a high math score of 95? Think of a way!"
Lin Yuxiang looked at the two teammates who had reached a consensus in confusion, and couldn't help asking weakly: "Um...is there anything I can do to help?"
This is the case for Lu Zhou, for example.
Going beyond the stem information, there are three questions in total:
Questions AB are judged separately. Since question A is so scary, there are bound to be many candidates for question B. At this time, it is time to show the courage of "knowing that there are tigers in the mountains, but go to the tiger mountains", leave the single-plank bridge to thousands of troops, and walk your own Yangguan Avenue in a cool way!
[Question 2: In order to ensure the landing orbit of Chang'e-3 and the optimal control strategy in the six stages, it is necessary to minimize fuel consumption as the goal. On this basis, analysis is performed, using the parameters obtained in Question 1, and using Matlab software to identify the numbers. The algorithm of obstacles in the elevation map realizes the identification of obstacles and the positioning of landing points, and simulates the optimal landing trajectory by establishing a model...]
This way, there will be almost no disagreements among team members!
Lu Zhou shook his head: "Choose question A."
At eight o'clock, the bell rang.
He had the heaviest task and the largest amount of work to be completed. He could only take a nap the next day, so he didn't even bring any clothes to change and went empty-handed. The first thing I did when I arrived at the new dormitory was to lie down on the bed and sleep.
"I will handle it."

(3) Conduct corresponding error analysis and sensitivity analysis for the landing trajectory and control strategy you designed.
"I seemed to have done something similar a few days ago. I seemed to be designing a launch plan for the Shenzhou rocket... But I thought such a mysterious subject would never be published. I didn't expect... I was careless!"
Wang Xiaodong looked at Lu Zhou, "How about choosing question B?"
Wang Xiaodong showed a smile that he thought was very gentle and said. He was just about to say handsomely, "Just leave it to me." However, before his emotions could brew on that paralyzed face, he was immersed in writing a draft on the A4 paper. Lu Zhou, without raising his head, said unceremoniously: "Bring food and water, please."
Teacher Liu came over and walked around, smiled and said hello to Lu Zhou and the other three. He didn’t talk about the competition, but just asked, "How was your rest last night?" and "Are you used to the dormitory on the old campus?" ?" and so on, then he wandered outside the computer room and drove back to the new campus to work on his own projects.
The previous one involves orbit calculation in aerospace physics. High school physics knowledge alone is definitely not enough. Question B is very simple on the surface, but in fact it is not much easier than the first question. It involves the dynamic motion analysis of the table legs. A series of issues such as material stress analysis and so on involve not only mathematical modeling knowledge, but also require a certain degree of involvement in structural mechanics, materials science and even ergonomics.
Even if you can't sleep, you have to force yourself to fall asleep.

A series of issues such as material stress analysis and so on involve not only mathematical modeling knowledge, but also require a certain degree of involvement in structural mechanics, materials science and even ergonomics.
Generally speaking, topic selection must be controlled within half an hour, and everyone is racing against time to read the questions.
(1) Determine the positions of the peri-lunar point and far-lunar point of the landing preparation orbit, as well as the magnitude and direction of the corresponding speed of Chang'e-3.
The next morning, he woke up at five o'clock. He lay in bed with his eyes closed until seven o'clock. He went to the cafeteria to have breakfast. Lu Zhou met Wang Xiaodong and Lin Yuxiang and went to the school to prepare for the mathematical modeling competition. Dedicated computer room.
Both questions are related to physics.
Wang Xiaodong: “…”
Wang Xiaodong looked at Lu Zhou, "How about choosing question B?"

At this time, it is time to show the courage of "knowing that there are tigers in the mountains, but go to the tiger mountains", leave the single-plank bridge to thousands of troops, and walk your own Yangguan Avenue in a cool way!
The sky collapse begins.
According to the official registration information, this competition has more than 70,000 college students in 25,347 teams from 33 provinces, municipalities, and autonomous regions across the country (including Hong Kong and Macao) as well as 1,338 universities in the United States and Singapore. At the same time, click on the competition website to download the questions to participate Contest.
And Liu Rui... This guy seems to have a very reliable figure in his team. He has already finished reading the questions and started assigning tasks to his two teammates.
Even if you can't sleep, you have to force yourself to fall asleep.
The first one is completely impossible if you don’t have enough physics knowledge. The second one can be done by collecting information through the Internet and finding ways to turn it into mathematical problems to solve.
However, when they saw the title, everyone was dumbfounded.

"Question A?" Wang Xiaodong frowned, "Are you okay?"
"Question A?" Wang Xiaodong frowned, "Are you okay?"
The competition is co-sponsored by the Department of Higher Education of the Ministry of Education and the Chinese Society of Industrial and Applied Mathematics. Due to the rigor and impartiality of the evaluation, although its influence is slightly less than that of the "Challenge Cup", the gold content of the national award is in some senses Better than the "Challenge Cup".
According to the rules, the questions are divided into four major questions ABCD, among which AB belongs to the undergraduate group and CD belongs to the junior college group. Each team chooses a question as their goal, completes and uploads the md5 code generated by the official website software within 72 hours, and uploads the paper in PDF format corresponding to the md5 code on the day the competition ends.
[Question 1: In order to obtain the positions of the peri-lunar point and far-lunar point of the landing preparation orbit, as well as the magnitude and direction of the corresponding speed of Chang'e-3, we first use mechanical knowledge and known conditions to calculate. Using extreme thinking, the motion of Chang'e-3's main deceleration stage is divided into infinite linear motions with uniform speed. Use Matlab software to design a program to perform iterative calculations on the main deceleration stage...]
At 7:30 in the morning, the computer room was already filled with ten teams.
Wang Xiaodong: “…”
However…
"The abstract part is a summary of the full text. This part can be completed after the entire article is written. The focus is on the problem analysis after the restatement of the problem, which involves all the ideas of the entire modeling. The soul of the entire paper is here ." Biting the ballpoint pen, Lu Zhou tapped the keyboard with his fingers to write out the outline of the paper, and then began to define the most critical soul of his paper based on the previous draft.
Although many people choose to use their own laptops to answer questions, usually they still bring their computers to the computer room. After all, only the WiFi in the computer room and library can download papers from CNKI for free. If you hope to win this kind of competition through unverified information on Baidu, it is better to burn a stick of incense and wait for the paper to be completed automatically.

Wang Xiaodong nodded expressionlessly, naturally understanding the meaning of Lu Zhou's last words.
But there are also experts in it.
"Question A?" Wang Xiaodong frowned, "Are you okay?"
The moment he completed the analysis of the problem, he felt that his brain was extremely clear, and he even had a rough framework in his mind for the entire paper's writing ideas.
Teacher Liu came over and walked around, smiled and said hello to Lu Zhou and the other three. He didn’t talk about the competition, but just asked, "How was your rest last night?" and "Are you used to the dormitory on the old campus?" ?" and so on, then he wandered outside the computer room and drove back to the new campus to work on his own projects.

This will become their team's biggest advantage!
Making eye contact, the two top students had reached a consensus.

For example, Luo Rundong, the second top student in Lu Zhou's class, was quietly communicating with his teammates with a calm expression.
Of course, this was the choice Lu Zhou made after he was confident about Question A.
"Designing a table... What can be designed about a table? Isn't it just four legs? It's foldable... Let's put a spring behind the stool legs?"
This way, there will be almost no disagreements among team members!

Wang Xiaodong nodded expressionlessly, naturally understanding the meaning of Lu Zhou's last words.
"Question A?" Wang Xiaodong frowned, "Are you okay?"
The "mathematical genius" on the team is just a sophomore and has even just started a physics class.
However, when they saw the title, everyone was dumbfounded.
Lu Zhou entered the state and concentrated his whole body on the topic in front of him.

The remaining work is to translate this outline into the language of mathematics...
The computer room was quite lively, and it could be seen that the students were all confused by this question and had no idea how to start.

The day before the competition, Lu Zhou and others took the school bus back to the old campus from the new campus and moved into temporary dormitories arranged by the school.
According to the official registration information, this competition has more than 70,000 college students in 25,347 teams from 33 provinces, municipalities, and autonomous regions across the country (including Hong Kong and Macao) as well as 1,338 universities in the United States and Singapore. At the same time, click on the competition website to download the questions to participate Contest.
"Question A?" Wang Xiaodong frowned, "Are you okay?"
The previous one involves orbit calculation in aerospace physics. High school physics knowledge alone is definitely not enough. Question B is very simple on the surface, but in fact it is not much easier than the first question. It involves the dynamic motion analysis of the table legs. A series of issues such as material stress analysis and so on involve not only mathematical modeling knowledge, but also require a certain degree of involvement in structural mechanics, materials science and even ergonomics.
Although many people choose to use their own laptops to answer questions, usually they still bring their computers to the computer room. After all, only the WiFi in the computer room and library can download papers from CNKI for free. If you hope to win this kind of competition through unverified information on Baidu, it is better to burn a stick of incense and wait for the paper to be completed automatically.
The sky collapse begins.
This way, there will be almost no disagreements among team members!
[To analyze the error of the landing orbit control strategy designed in question 2, we must first list as many factors as possible that may cause the error and analyze them...]
[Question 1: In order to obtain the positions of the peri-lunar point and far-lunar point of the landing preparation orbit, as well as the magnitude and direction of the corresponding speed of Chang'e-3, we first use mechanical knowledge and known conditions to calculate. Using extreme thinking, the motion of Chang'e-3's main deceleration stage is divided into infinite linear motions with uniform speed. Use Matlab software to design a program to perform iterative calculations on the main deceleration stage...]

"I have already finished college physics. Although aerospace physics seems complicated, in the final analysis it is just the content of the first three chapters." After a pause, Lu Zhou glanced at the team next to him and continued, "Besides, you see In this computer room alone, there are already enough people choosing question B."
"I'm studying advanced mathematics, not how to reach heaven!"
The next morning, he woke up at five o'clock. He lay in bed with his eyes closed until seven o'clock. He went to the cafeteria to have breakfast. Lu Zhou met Wang Xiaodong and Lin Yuxiang and went to the school to prepare for the mathematical modeling competition. Dedicated computer room.
(2) Determine the landing orbit of Chang'e-3 and the optimal control strategy in the six stages.
Teacher Liu came over and walked around, smiled and said hello to Lu Zhou and the other three. He didn’t talk about the competition, but just asked, "How was your rest last night?" and "Are you used to the dormitory on the old campus?" ?" and so on, then he wandered outside the computer room and drove back to the new campus to work on his own projects.
"Question A: Chang'e-3 Soft Landing Orbit Design and Control Strategy...Question B: Creative Flat Folding Table?! Holding Grass? What the hell is this year's question?"
Don't think that it's easy to lie down if you win. If you don't let this guy do some work, Lu Zhou will feel unbalanced.
Questions AB are judged separately. Since question A is so scary, there are bound to be many candidates for question B. At this time, it is time to show the courage of "knowing that there are tigers in the mountains, but go to the tiger mountains", leave the single-plank bridge to thousands of troops, and walk your own Yangguan Avenue in a cool way!
The day before the competition, Lu Zhou and others took the school bus back to the old campus from the new campus and moved into temporary dormitories arranged by the school.
Lin Yuxiang looked at the two teammates who had reached a consensus in confusion, and couldn't help asking weakly: "Um...is there anything I can do to help?"
Of course, this was the choice Lu Zhou made after he was confident about Question A.
The "mathematical genius" on the team is just a sophomore and has even just started a physics class.
This is the case for Lu Zhou, for example.
However…
For most teams, the paper is usually placed after the modeling and programming are completed, but for Lu Zhou, the two can be carried out simultaneously!
Both questions are related to physics.
"Question A: Chang'e-3 Soft Landing Orbit Design and Control Strategy...Question B: Creative Flat Folding Table?! Holding Grass? What the hell is this year's question?"
Of course, this was the choice Lu Zhou made after he was confident about Question A.
The advantage of mathematical modeling and paper writing being completed by one person is that many tasks that require communication between two people can be completed by one person, without problems such as teammates' tacit understanding and expression and understanding ability.
Wang Xiaodong nodded expressionlessly, naturally understanding the meaning of Lu Zhou's last words.
The sky collapse begins.
Making eye contact, the two top students had reached a consensus.
But there are also experts in it.
[To analyze the error of the landing orbit control strategy designed in question 2, we must first list as many factors as possible that may cause the error and analyze them...]
"Okay then, I'll leave the modeling to you."
At eight o'clock, the bell rang.
"I have already finished college physics. Although aerospace physics seems complicated, in the final analysis it is just the content of the first three chapters." After a pause, Lu Zhou glanced at the team next to him and continued, "Besides, you see In this computer room alone, there are already enough people choosing question B."

After a pause, Lu Zhou glanced at the team next to him and continued, "Besides, you see In this computer room alone, there are already enough people choosing question B."
Making eye contact, the two top students had reached a consensus.
"I will handle it."
This way, there will be almost no disagreements among team members!
For example, Luo Rundong, the second top student in Lu Zhou's class, was quietly communicating with his teammates with a calm expression.
Making eye contact, the two top students had reached a consensus.
"Question A?" Wang Xiaodong frowned, "Are you okay?"

Wang Xiaodong nodded expressionlessly, naturally understanding the meaning of Lu Zhou's last words.
Generally speaking, topic selection must be controlled within half an hour, and everyone is racing against time to read the questions.
The moment he completed the analysis of the problem, he felt that his brain was extremely clear, and he even had a rough framework in his mind for the entire paper's writing ideas.
The next morning, he woke up at five o'clock. He lay in bed with his eyes closed until seven o'clock. He went to the cafeteria to have breakfast. Lu Zhou met Wang Xiaodong and Lin Yuxiang and went to the school to prepare for the mathematical modeling competition. Dedicated computer room.

Wang Xiaodong showed a smile that he thought was very gentle and said. He was just about to say handsomely, "Just leave it to me." However, before his emotions could brew on that paralyzed face, he was immersed in writing a draft on the A4 paper. Lu Zhou, without raising his head, said unceremoniously: "Bring food and water, please."
[Question 2: In order to ensure the landing orbit of Chang'e-3 and the optimal control strategy in the six stages, it is necessary to minimize fuel consumption as the goal.

"I'm studying advanced mathematics, not how to reach heaven!"
On September 12th, the competition will go on as scheduled!
Wang Xiaodong nodded expressionlessly, naturally understanding the meaning of Lu Zhou's last words.
The mattresses and pillows are all prepared. You only need to bring a sheet. Those who are not particular about it can even go directly to the private room. After all, although the competition time is 72 hours, the average bedtime for each person may be ten consecutive hours. Less than an hour.
"Designing a table... What can be designed about a table? Isn't it just four legs? It's foldable... Let's put a spring behind the stool legs?"
There is no shortage of people for modeling, programming, and papers, but there is a shortage of errand boys.
However…
But there are also experts in it.
"I'm studying advanced mathematics, not how to reach heaven!"
And Liu Rui... This guy seems to have a very reliable figure in his team. He has already finished reading the questions and started assigning tasks to his two teammates.
Don't think that it's easy to lie down if you win. If you don't let this guy do some work, Lu Zhou will feel unbalanced.
Questions AB are judged separately. Since question A is so scary, there are bound to be many candidates for question B. At this time, it is time to show the courage of "knowing that there are tigers in the mountains, but go to the tiger mountains", leave the single-plank bridge to thousands of troops, and walk your own Yangguan Avenue in a cool way!
Lin Yuxiang didn't complain at all, and nodded enthusiastically: "Yeah, yeah, I'll take care of it!"

The remaining work is to translate this outline into the language of mathematics...
"I'm studying advanced mathematics, not how to reach heaven!"
Lin Yuxiang didn't complain at all, and nodded enthusiastically: "Yeah, yeah, I'll take care of it!"
Lu Zhou shook his head: "Choose question A."

The computer room was quite lively, and it could be seen that the students were all confused by this question and had no idea how to start.
This way, there will be almost no disagreements among team members!
At the same time, with the modeling paper in hand, Lu Zhou, as the team leader, can accurately issue orders to Wang Xiaodong, who is responsible for the programming aspect.

This is the case for Lu Zhou, for example.
(1) Determine the positions of the peri-lunar point and far-lunar point of the landing preparation orbit, as well as the magnitude and direction of the corresponding speed of Chang'e-3.
Lin Yuxiang didn't complain at all, and nodded enthusiastically: "Yeah, yeah, I'll take care of it!"
The computer room was quite lively, and it could be seen that the students were all confused by this question and had no idea how to start.
"Hold the grass, boss, don't you have a high math score of 95? Think of a way!"

"The abstract part is a summary of the full text. This part can be completed after the entire article is written. The focus is on the problem analysis after the restatement of the problem, which involves all the ideas of the entire modeling. The soul of the entire paper is here ." Biting the ballpoint pen, Lu Zhou tapped the keyboard with his fingers to write out the outline of the paper, and then began to define the most critical soul of his paper based on the previous draft.
Everyone quickly logged into the official website and downloaded the questions.
The mattresses and pillows are all prepared. You only need to bring a sheet. Those who are not particular about it can even go directly to the private room. After all, although the competition time is 72 hours, the average bedtime for each person may be ten consecutive hours. Less than an hour.
Wang Xiaodong looked at Lu Zhou, "How about choosing question B?"
The previous one involves orbit calculation in aerospace physics. High school physics knowledge alone is definitely not enough. Question B is very simple on the surface, but in fact it is not much easier than the first question. It involves the dynamic motion analysis of the table legs.

For example, Luo Rundong, the second top student in Lu Zhou's class, was quietly communicating with his teammates with a calm expression.
At 7:30 in the morning, the computer room was already filled with ten teams.
He had the heaviest task and the largest amount of work to be completed. He could only take a nap the next day, so he didn't even bring any clothes to change and went empty-handed. The first thing I did when I arrived at the new dormitory was to lie down on the bed and sleep.
