说明：  LSDYNA自定义本构模型文件, 很实用(LSDYNA User Defined Materials)

算法交易，统计套利，配对交易python代码实现(Algorithm trading, statistical arbitrage, pair trading, Python implementation)

将flac3.0代码转换为flac5.0代码(Convert flac3.0 code to flac5.0 code)

基于PSCAD4.2软件的单相桥式全控整流电路仿真(Simulation of single phase bridge full controlled rectifier circuit based on PSCAD4.2 software)

智能除湿器可以实现在封闭空间内保持空气湿度，当湿度传感器采样的信号超过设定值，就一会显示并开启除湿器进行降低湿度，包括主程序、采样程序和显示程序(The intelligent dehumidifier can keep the air humidity in the closed space. When the signal of the humidity sensor exceeds the set value, it will display and open the dehumidifier to reduce the humidity, including the main program, the sampling program and the display program.)

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.)

说明：  基于RTDS的电网STATCOM模型，可以用RTDS软件打开(RTDS-based grid STATCOM model can be opened with RTDS software)
