说明：  PSCAD仿真软件下搭建的DVR模型！！(PSCAD simulation software to build the model of the DVR! !)

基于PSCAD 4.5搭建的IEEE标准2区4机11节点模型，参数配置正确，潮流计算结果正确。(PSCAD 4.5 build local area based on IEEE 4 2 11 node model, all the parameters have been configured correctly, flow calculation results are accurate.)

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 )

是wrf高级图形界面绘制图,结合原先的ncl所有的功能，且操作简单快捷，绘制出得图形效果好(Advanced graphical interface is wrf drawn map, combined with the original ncl all the features, and the operation is simple and quick to draw a very good graphics)

用了五年多时间打造的基于跨平台开发技术qt开发的图形组态系统，运用模板能组合成任意图元，运用脚本能，定义出图元根据属性的变化，做出相应的动态效果，首先应用于电力系统网路图，监控电网状态。可以应用于实时监控应用领域。超一流的绘制效果，在完成电力系统一次接线图比组态王、三维力控有更好的绘制效果.增加实时数据、web浏览器、后台进程取数，qwt做实时曲线，vista风格等、存成svg文件网上发布，升级到4.6.3等(部分源)(graph )

三次bezier曲线的绘制（其中调用pow（））。(The drawing of cubic Bezier curve (where pow ()).)

仿真超声图像的源代码 A program fot the simulation of ultrasound systems is presented.It is based on the TUpholme-Stepanishen mehtod, and is fast because of the use of a far-field approximation. (Simulation of ultrasound images of the source code A program fot the simulation of ultrasound systems is presented.It is based on the TUpholme-Stepanishen mehtod, and is fast because of the use of a far-field approximation.)

计算两条曲线的相似度，作为判断两条曲线相似度的依据(to calculate the frechet distance of two curves)

二维图绘制的C#小程序,能生成二维图像。(about Drawing with C#)

说明：  一个简单的C语言开发的CAD二维画图软件，对刚刚开始学习大型程序设计的学习者有一定帮助(A simple CAD two-dimensional drawing software developed in C language is helpful for learners who are just beginning to learn large-scale programming.)
