对图片进行网格划分，以及绘图获得区域，最终获得灰度矩阵(Mesh the image, and draw the region to obtain the gray scale matrix)

本程序实现了计算机图形学的一些重要算法（画直线，画圆，画椭圆，区域填充，图形裁剪，齿轮生成，三次样条曲线等等），源码和可执行程序均打包于文件中(this program is implemented some important algorithm of computer graphics such as drawing lines,drawing circles,drawing ellipse,area filling,Graphics clipping，gear wheel generation ，three times spline curve and so on），source code and executable files are all included in the compressed file。 )

分析计算大规模数据的线性度的一个小程序，可绘图，m文件(Linearity analysis and calculation of data, can be a drawing, m file)

三次样条曲线的绘制和三次B样条曲线的绘制(Cubic spline curve drawing and cubic B-spline curve drawing)

PSCAD基于两端两电平的柔性直流输电模型，对于研究直流输电建模是一个非常好的参考！(HVDC flexible model based on the two ends of PSCAD level, the study HVDC modeling is a very good reference!)

说明：  lisp学习应用 这个挺好的 建议大家学习一下 反编译也不错 就是没工具 那就下一个吧 还挺麻烦 随便上传一个小程序 呼伦一下吧(lisp CAD vba would did like a little piggie ?I like the fat pig,so I will buy a big fat pig and a little doggie .)

说明：  实现对单图层dxf文件的信息采集，例如直线的起止点、圆弧的圆心与半径等(Achieving Information Collection of DXF Files with single layer)

在前人工作的基础上对三层层状介质的瑞利波频散曲线进行了正演模拟研究，对假定的几组典型模型参数的频散曲线进行了认真分析。通过分析可知，各频散曲线之间是互不相交的，从而对此问题有了一个更清晰的认识。指出当低速软弱夹层存在时频散曲线的特点，并根据分析结果，说明”之“字形频散曲线的形成机理。(On the basis of previous work, the Rayleigh wave dispersion curves of three layered media are studied by forward simulation, and the dispersion curves of some assumed typical model parameters are carefully analyzed. Through the analysis, we can see that the dispersion curves are not intersected with each other, so we have a clearer understanding of this problem. It is pointed out that the characteristic of time dispersion curve exists in low-speed weak interlayer, and according to the analysis results, the formation mechanism of zigzag dispersion curve is explained.)

说明：  c#语言 Devexpress设计的界面。 基于ArcEngine的基础设计 包括：打开、保存、另存地图文档， 地图的放大、缩小、平移等， 图层的移动、删除、显示属性表等， 绘制图形:画线、画面、画圆、画矩形等， 空间数据的导入等。(c# language Devexpress design interface. ArcEngine based on the design include: Open, Save, Save the map document, map zoom, pan, etc., layers move, delete, display the property sheet, etc., draw the graph: draw lines, pictures, circle, rectangle and other spatial data import and so on.)

DFX格式的文件操作例子,可以读出由CAD绘制的保存为DFX格式的图片,附带大量注释(DFX format file manipulation example, can read out by the CAD drawing for the preservation DFX format photographs, Notes of a large number of fringe)
