步进电机转动原理

这段代码是用来求希尔伯特变换的，希望对大家有用(The Hilbert transform )

输入一串数，将偶数分解为两个质数，如8=3+5，只取第一组，就是后面出现的8=5+3不再打印。(Enter a string of numbers, the even number into two prime numbers, such as 8 = 3+5, just take the first group, is behind the emergence of 8 = 5+3 no longer print.)

Visual C# 随机分组抽签程序，可用于抽签、摇奖等场合，人员分组抽奖情况人数项请输入大于0的整数，不要输入空组别名，各组别的总人数大于参与抽签人数，各组别的总人数需要大于1。还需要确定参与抽签人员、抽签分组组别等。程序还可进行简单的维护管理，比如添加人员、添加级别、删除组员等功能。这个程序从整体上来说，写的挺好，不管是界面方面或是功能方面，都挺好用，推荐给大家。
