10kV_SVG

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.)

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.)

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)

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. )

用四阶龙格-库塔法求系统在U单位阶跃输入下该系统的响应曲线(Using the four order Runge Kutta method to find the response curve )

这是国外的同行编写的画图板程序，感觉比陈建春的要好些，说实话研究了半天，发现国内的cad水平低不是因为国内的人笨，主要是国外的cad技术不能很快的传递到国人手中，总是参考陈建华等水平有限，工程水平差的书籍造成整体水平低，书中没有详细的流程图，和软件设计思路，而且代码错误连篇。(This is the foreign counterparts of the drawing board to prepare procedures, CHEN Jian-chun than feeling the need to better tell the truth for a long time study and found that low levels of domestic cad because people are not stupid, mainly abroad cad technology should not quickly delivered to the the hands of the people always refer to Chen Jianhua, such as the limited level, engineering level difference caused by the overall level of books low, the lack of a detailed flow chart of the book, and software design, and code errors pack.)

计算机图形学，mfc实现二维图形的基本几何变换，如平移、旋转、缩放、对称、错切变换(Computer graphics, mfc achieve the basic two-dimensional graphics geometric transformations, such as translation, rotation, scaling, symmetry, shear transformation)

克里金插值计算，一种拟合算法，主要用于等值线应用。(Kriging interpolation calculation, a fitting algorithm, mainly for the application of contour lines.)

这是一个模拟acdsee软件打开一幅bmp文件并显示在屏幕上的算法.(This is a simulation software Converter opened a bmp file and display on the screen of the algorithm.)

MFC做的画图软件 只能画直线 还有待改进 适合初学者 看看(MFC do draw a straight line drawing software can be improved for beginners look)
