跳动的小球,主要是做出小球的跳动效果，不知道做得行不-Beating a small ball, the ball is mainly made by the beating effect of

用数据库和jsp编写添加，查询的营业网点项目(Use database and JSP to compile business outlet items that add and query)

说明：  运用MATLAB完成信号抽样以及对抽样信号的频谱进行分析，信号抽样是利用抽样脉冲序列从连续信号中抽取一系列的离散值，通过抽样过程得到的离散值信号称为抽样信号，记为。从数学上讲，抽样过程就是信号相乘的过程(Using MATLAB to complete signal sampling and analyze the spectrum of the sampled signal)

说明：  使用A星算法进行路径规划，能搜索上、下、左、右、左上、左下、右上、右下八个方向(We use A-star algorithm for path planning, and the algorithm can search 8 directions.)

传统的三相电机空间矢量控制方法会引起很大的，频率很高共模电压，本程序采用相对矢量合成零矢量，降低了共模电压的幅值和频率(The traditional space vector control method of three-phase motor will cause great common-mode voltage with high frequency. This program uses relative vector to synthesize zero-vector, which reduces the amplitude and frequency of common-mode voltage)
