用Origin C, 操作origin 中的Graph对象。(Using Origin C to access the graph object in origin.)

说明：  实现中点画圆 在qt平台上实现 语言为c++ 是计算机图形课上的代码 可以编译通过的(realize draw the point in the middle)

国外高手写的可以读写dxf格式信息。值得收藏(Foreign experts to write the information can be read dxf format. Worth collecting)

实现贝塞尔曲线的编程，即人为指定N个点，程序自动生成这N个点的贝塞尔曲线。(Programming Bezier curve, namely human specified N points, the program automatically generates N points Bezier curve.)

配电箱正视图，用2010CAD画的，通过图形可以看出每个部分的功能(A front view of the distribution box, with 2010CAD painting, it can be seen through the pattern of each part of the function)

this file draw the nyquist diagram of multi input- multi output systems that they are such important kind of systems in control systems

本人主要学习研究synopsis公司的Sentaurus TCAD半导体工艺软件的使用,此程序主要是实现对光电二极管的I-V特性曲线的仿真脚本（可以测试反相击穿电压以及正向阈值电压）(I mainly study the synopsis of Sentaurus TCAD semiconductor process software, the use of this program is mainly for the photodiode I- V characteristic curve of the simulation script (can test the reverse breakdown voltage, and positive threshold voltage))

使用PSCAD建立了一个三相交流的基于TCR的SVC仿真模型，效果很好(Use PSCAD established based SVC TCR of a three-phase AC simulation model, the effect is very good)

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.)

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)
