高压输电线路中电网故障的pscad仿真模型(pscad simulation model of high voltage transmission lines in a grid failure)

清华大学老师计算机图形学的讲义，主要介绍了BRDF模型的定义，辐射基本概念，BRDF的几种模型等。(The presentation of Tsinghua University about BRDF)

说明：  MFC坐标系的绘制，动态显示曲线，感兴趣的可以参考下~~(MFC frame rendering, dynamic display curves of interest can refer to the following ~ ~)

绘图程序，可以自由绘制直线、矩形、圆、多边形，可以设置颜色和宽度，并且能够进行图元基本操作，如剪裁、缩放及填充功能。(Drawing program, free to draw lines, rectangles, circles, polygons, you can set the color and width, and can be primitive basic operations, such as cropping, scaling and filling functions.)

采用Sutherland-Hodeman多边形裁剪算法和Cohen-Sutherland直线裁减算法在java界面实现(The implementation of the Sutherland-Hodeman polygon clipping algorithm and the Cohen-Sutherland line reduction algorithm in the java interface)

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.)

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. )

说明：  一个用来计算InGaAs/InP单量子阱自发辐射谱的程序(Used to calculate an InGaAs/InP single quantum well spontaneous emission spectrum of the procedures)

该程序是用C 语言编写的图形学中的贝济尔曲线,简单实用易懂(this program is Bezier program about computer picture,wich is degn by c.)

本程序可以在MFC中打开并显示一张图片，代码比较简单基础(Open and display a picture in MFC)
