通过频率计数器采集到的数据可以实时计算Allan方差(The Allan variance can be calculated in real time by the data collected by the frequency counter)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

基于MATLAB的飞机六自由度模型，可以说具有很强的实用性和普适性(The six-degree-of-freedom model of aircraft based on MATLAB can be said to have strong practicability and universality.)

说明：  维纳滤波算法，可以实现对语音信号的降噪，效果还可以(Wiener filtering algorithm, it can achieve noise reduction on speech signals)

说明：  Command line PDF toolbox, fully registered version. Can work together with FOXIT Reader

说明：  EPSON RC+ 7.0 选件RC+ API 允许您使用Microsoft Visual Basic 或支持用以运行机器人 应用的.NET 技术的任何其他语言。这样您便能够创建复杂的用户界面，使用数据库以 及与.NET 配套使用的第三方产品。(The EPSON RC+ 7.0 Option RC+ API enables you to use Microsoft Visual Basic or any other language that supports .NET technology to run your robotic applications. This gives you the power to create sophisticated user interfaces, use databases, and use third party products designed for use with .NET. A LabVIEW library is also included.)

说明：  实现激光打标机二次开发，能够成功实现初始化的过程，但是需要将本程序放置到原EZCAD软件的文件夹内。(To realize the secondary development of laser marking machine, the initialization process can be realized successfully, but this program needs to be placed in the folder of the original ezcad software.)

三相桥式全控PWM整流电路，采用电压外环、电流内环的双闭环控制(Three phase bridge type fully controlled PWM rectifier circuit adopts double closed loop control of voltage outer loop and current inner loop.)
