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.)

端面抽运Yb石英光纤激光器理论计算，matlab程序(end pumping of Yb doped fiber lasers)

一个仿真光栅的程序，可以通过设计kappa，长度来计算光栅放射参数(a grating simulation Matlab code)

C# 控制X,Y，Z 三个轴的运动，通过串口的方式通信(C# controls the movement of X, Y and Z axes and communicates through serial ports)

KTV点歌系统：包括拼音点歌、分类点歌、排行点歌、字数点歌。本系统由北大青鸟学员所作！(KTV VOD system: including Pinyin song, classification VOD Top song, word song. This system made by the Beida Jade Bird trainees!)

说明：  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.)

该MATLAB仿真程序适用于蓄电池的充电以及放电控制(The MATLAB simulation program is suitable for battery charging and discharge control.)

说明：  参数化电离层模型：用于计算电离层电子密度(Parameterized Ionosphere Model (PIM): Calculate the ion density)
