用有限元方法解偏微分方程的算例。区域是[0,1]*[0,1]的正方形区域，区域剖分网格是标准正方形。区域剖分、节点计算、转化成代数方程求解，结果画图显示及txt结果输出，每一步都很详细。(Two-dimensional numerical example of using the finite element method for solving partial differential equations . Region is a [0,1]* [0,1] of the square region, a square region of a standard mesh grid. Regional split, node calculation, converted into algebraic equations, the results display and txt file result output, each step is very detailed.)

隔离准Z源逆变器的开环控制，希望对初学者有些帮助。(Isolation the open-loop control of Z source inverter, and want some help for beginners. )

在PID控制中，微分信号的引入可改善系统的动态特性，但也易引起高频干扰。在误差扰动突变时尤其显出微分项的不足。若在控制算法中加入低通滤波器，则可使系统性能得到改善。(In PID control, the introduction of differential signal can improve the dynamic characteristics of the system, but it can also cause high-frequency interference. When error perturbations change abrupt, the deficiency of differential terms especially shows. If the low-pass filter is added to the control algorithm, the performance of the system can be improved.)
