简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)

CAD下VBA二次开发，用来展高程点，txt文件，已经把离散点网格化了(CAD lower VBA secondary development, to show elevation point, txt file, has the discrete points of the grid)

绘画出三阶的贝塞尔曲线, 求出曲线上各点的曲率和半径,可用于弯道设计(Drawing out the order of the Bezier curve, find the points on the curve and radius of curvature, can be used for curve design)

说明：  这个软件是用在CAD里的，给尺寸加公差上去很方便。(This software is used in the CAD in the, tolerances up to plus size is very convenient.)

用MATLAB画地图，有中国地图，美国地图以及世界地图。(Use MATLAB to draw maps, map of China, map of the United States and the world map.)

根据图框块自动识别图纸并预览打印。函数参数分别为：打印机名称，打印样式，打印纸张，打印份数，自动纸张，自动旋转，自动关闭，自动识别图框(Autoprint according to the drawing blocks.)

DDA方法的绘制直线 圆的绘制 曲线的绘制等(tu xing xue)

基于PSCAD 4.5搭建的IEEE标准2区4机11节点模型，参数配置正确，潮流计算结果正确。(PSCAD 4.5 build local area based on IEEE 4 2 11 node model, all the parameters have been configured correctly, flow calculation results are accurate.)

2次B样条曲线和3次B样条曲线的matlab绘制，适用于初学者(Two B spline curve and cubic b-spline curve realization code, debugging through matlab, apply for beginners )

在pscad中运用mutirun完成高压直流输电相关设计(apply mutirun in pscad to complete HVDC)
