利用SAR卫星的已知的多个时刻的位置和速度信息，精确地拟合出SAR卫星的轨道模型。可用于计算出任意象元成像时刻卫星的位置-SAR satellites known to use multiple moments of position and velocity information, accurately fitted SAR satellite orbital model. Images can be used to calculate the yuan as the location of satellite imaging time

游戏规则 目的：在本游戏中，你将作为一名裁缝，将尽可能多的纽扣穿成 一个闭合的路线。游戏初始有 15 个纽扣，随着时间的增 加，纽扣数目也增加，当达到70个时游戏即结束。 规则：只能在有纽扣的点穿线，且只能在水平方向或竖直方向穿 线。线可交叉，但有纽扣的点不能交叉连接。 秘诀：要尽可能使连线长且该连线上的纽扣数多。-Rules of the game Objective: In this game, you will serve as a tailor, will be wearing buttons as much as possible into a closed line.

使用python实现青蛙过河，在程序中调用button与graphics模块，将每个青蛙包装为一个模块，点击后可以判断跳动方向并向左或右移动、以及根据边上青蛙的个数自行判断决定是否越过一只青蛙，当最终所有青蛙成功调换位置后，显示“success”，另外，利用stack实现可后悔之前步骤。
