利用matlab绘制Rotman透镜，并用简单的随机搜索进行性能优化，优化部分算法比较简单，可自行改用更有效的算法(Design Rotman Lens with matlab)

PSCAD做的12模块H桥SVG模型，电流矢量控制，运行良好。(PSCAD do SVG module 12 H bridge model, the current vector control, work well.)

这是一个简单的画圆功能，主要让用户学会如何利用Windows提供的画图工具，用户单击鼠标右键则会弹出对话框选择线宽，在菜单上也设计了圆的颜色选择菜单。(This is a simple function of the Circle. mainly for users to learn how to use Windows for the drawing tools, Users right-click pop-up dialog box will be chosen linewidth, the menu also designed a circular color choice menu.)

观察Autocad内部数据组织的最佳工具,这个对应Autocad2(observation Autocad internal data organization the best tools, and corresponding Autocad2)

自己在PSCAD中搭建的PLL，用的是分立元件搭建的，有助于自己学习以及编程实现，已经与自带的PLL进行对比，验证了正确性(PSCAD built himself in the PLL, using discrete components built to help you learn and programming has been compared with the built-in PLL, verify the correctness)

实现绘制5个圆形组成的图案，继承Jpanel类的DrawPanel内部类，并重写paint()方法。(Plotting of five circular pattern composed of inherited Jpanel class DrawPanel inner class, and override paint () method.)

用于生成六边形阵列，同时根据约束可以变成各种阵列形状。(Used to generate hexagonal arrays, at the same time under the constraint can be turned into the shape of a variety of arrays.)

（修正）剑桥模型排水条件下应力应变曲线作图全过程，有源程序((Amendment) Cambridge model drainage conditions, the stress-strain curve plotted the whole process, the source code)

本文以电场的三大定理、连续超张弛迭代算法、拉格朗日插值算法等原理知识作为理论基础，以 C 语言为编程工具，将由根据以上物理和数学原理所推导出来的模型转化为可以计算像管内电势的 CAD 程序软件。所编写的程序可以在给定像管参数和电极电位的情况下，计算圆柱形像管内任意一点的电位大小，并绘制出像管内的等势线；拉格朗日插值得到对称轴上任一点的电位值。 (In this paper, we base on the three theorems of the electric field, continuous ultra-relaxation iterative algorithm, and Lagrange interpolation algorithm. We use the C language as a programming tools, and transform the model derived above into a CAD software to calculate the electric potential in the image tube. In case the image tube parameters and electrode potential are known, the program written can get the potential of every point in the image tube, and plot equipotential lines inside the image tube. It can also get the potential of every point on the axis of symmetry by Lagrange interpolation. )
