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 .
