MFC画图板，可以画一些基本图形，如直线，椭圆，扇形，矩形，弦形，三角形。 可以保存为BMP的文件(MFC drawing board, you can draw some basic graphics, such as line, ellipse, sector, rectangle, string, triangle. Files that can be saved as BMP)

这个程序是用Breseham画法在visual c++平台下画直线和圆。可以对图像进行刷新，画多条直线，多个圆(This procedure is used Breseham paint in visual c++ platform for the next drawing a straight line and circle. Can refresh the image, painted more than a straight line, a number of round)

这是NURBS曲线的绘制程序，在MATLAB-2008a环境下进行编写，包含了几个基函数子程序。可以通过调节控制顶点和点的权重来调节曲面形状。 (This is a NURBS curve drawing program, in the MATLAB-2008a environments prepared, including a number of basis function subprogram. Can be controlled by adjusting the weight of vertex and point to adjust the surface shape.)

应用表面粗糙度曲线上寻找上下包络线，其过程：找到极大极小值，之后画出直线(envelop)

用于绘制任意阶次的bezier曲线，只需要输入节点坐标即可(The Bezier curve for drawing any order)

一个简单的程序，可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行，而没有在paint方法里进行，可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)

基于Bresenham算法的四步画直线算法,加快画直线速度(draw line based Bresenham update alogrith)

基于PSCAD 4.5搭建的IEEE 第一标准测试模型，可以用于次同步振荡的研究。(The first IEEE standard test models built based on PSCAD 4.5 can be used to study sub-synchronous oscillations.)

不同离焦下Mtf积分曲线随相位板参数的变化，进而用来选择合适的相位板(The Mtf integral curve along with the change of phase plate parameters to appropriate phase plate)
