修正后的goodman曲线疲劳极限图的绘制方法源程序(Amended goodman curve fatigue limit diagram drawing method source)

已知zernike多项式的系数大小，画出相应图形。(Given the Zernike term, draw the corresponding figure)

abaqus中的双曲正弦曲线代码，可以使用，并且与abaqus中的内在本构达到了很好的一致(abaqus the hyperbolic sine curve code can be used, and with the inherent constitutive abaqus reached a good agreement)

一些matlab平台的绘图程序，包括雷达图，fft频谱等。(Some drawing programs on the MATLAB platform include radar chart, FFT spectrum, etc.)

集中介绍了HDC,CDC,CClientDC,CPaintDC,CWindowDC的使用方法和区别，绘图显示效果，区分窗口客户区。(Focus on the HDC, CDC, CClientDC, CPaintDC, CWindowDC to use and distinction, graphics effects, to distinguish the window client area.)

使用matlab代码画语音信号的语谱图，可作为参考资料(Using matlab code to draw speech signal spectrogram can be used as reference.)

基于pscad的一个简单的500kv线路故障仿真模型(A simple model of 500kv line fault simulation based pscad)

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.)

利用此代码可画龙曲线，此代码仅供参考，希望大家学习并改进，(use of this code can be a dragon painted curves, the code for reference purposes only, we hope to learn and improve, thank you)

cad 转svg矢量图，很好用的工具，很有用，尽管放心使用(CAD SVG vector map, a very good tool, very useful, despite the ease of use)
