自己在PSCAD中搭建的PLL，用的是分立元件搭建的，有助于自己学习以及编程实现，已经与自带的PLL进行对比，验证了正确性(PSCAD built himself in the PLL, using discrete components built to help you learn and programming has been compared with the built-in PLL, verify the correctness)

DDA直线绘制程序实现，可以是任意的直线。(DDA line drawing program, a straight line can be arbitrary.)

说明：  使用MFC实现画摇杆的效果，同时画出摇杆的运动轨迹(Use MFC to realize the effect of drawing the rocker and draw the movement track of the rocker at the same time)

零阶一类贝塞尔函数曲线，并画出其包络线的源程序(Zero-order Bessel function curve and draw the envelope of the source)

这个程序是用Breseham画法在visual c++平台下画直线和圆。可以对图像进行刷新，画多条直线，多个圆(This procedure is used Breseham paint in visual c++ platform for the next drawing a straight line and circle. Can refresh the image, painted more than a straight line, a number of round)

python画柱状图，python画散点图，python画双y轴图，python画柱状图，python画散点图，python画双y轴图(Python draws a histogram)

VB版个性画图板附上源代码,有需要的就下载吧。(VB version of personality drawing board with the source code, there is a need to download it.)

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)

用VC++6.0开发的画图程序。可以绘制基本图形和填充各种颜色，绘制直线部分有些问题。请大家帮忙解决(The Paint program developed with VC++6.0. You can draw basic graphics and filled a variety of colors, draw a straight portion of some of the problems. Please help solve)

极其简单的MFC画图小例子，但是可以学到很多的基本知识，不错的例子，微软出品！！！！(Extremely simple MFC drawing small example, but you can learn a lot of basic knowledge, a good example, Microsoft Publisher! ! ! !)
