本文的程序实现在屏幕上随机产生不同大小的雪花，并以不同的速度下降。相对于第一版，它在很多性能上做了优化，直接在桌面的上下文中绘制雪花。而且，现在也通过RedrawWindow，实现在桌面的图标(如任务栏)上绘制雪花了。你可以用它来学习GDI。(Falling Snow on Your Desktop! Part II This article explains how to create an application that makes it snow on the desktop. Since my previous article was published, I received many user inquiries about how to improve the program. This article demonstrates how to create snow flakes that fall on your desktop, by using the draw functions directly in the desktop context. When the application starts, it creates an array of snow flakes and starts the timers for each flake. Manipulation of the RedrawWindow function allows the drawing of flakes behind and over the desktop icons, making the application more impressive. )

matlab系统响应求如LTI连续系统响应的数值解，可以看一看，绝对正确的程序(system response, such as matlab for LTI system response for the numerical solution, you can take a look at the absolutely correct procedures)

说明：  实现数字滤波（刚开始接触不知道分类对不对）请见谅(Digital filter (do not know the beginning of exposure classification is correct or not), please forgive me)
