Commemorating the first training model

For later Lin Xiaoqin !

Because the undergraduate group can only choose A,B One of the two questions , Our team can't make it 10 The topic was decided in five minutes , It's not rash ,B The relationship between the friction force of the physical model and the Hong Kong Zhuhai Macao Bridge is not very clear , The first feeling is that it's hard to start ~~~~~~~~~~~~~ about A topic , There are also ideas of optimizing and fitting the optimal solution .

+ Subsequent matlab Code, etc . I've heard about it before , But I still feel a little unfair …
And then I saw it , Search volume in just one day 10 ten thousand …

then , As expected , Here comes the official
In the meantime, the players A It seems that the government has changed one of the data in the question , I think it's really good , team member A Hurry to change the code data , Fortunately, it didn't make a big difference , Three questions have been completed, question one , Problem 2: I can't think of a compromise , Take care of distance, but not time , Take care of time, but not distance
<>3. on the third day
My computer broke down !AxMath stay word Used up in , what the hell excel Table cleaning data , Remind me excel If there is an error, do you want to fix it ,yes!
