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. )

数字滤波器的设计及性能比较 用三种方法设计FIR滤波器：窗口法、最大最小误差法、频率采样法；用两种方法设计IIR滤波器：冲激响应不变法、双线性变换法。很全的matlab滤波器程序！( Digital filter design and performance comparison of three methods to use FIR filter design: the window method, the largest minimum error method, frequency sampling method two ways IIR filter design: impulse response of the same law, two and transform. Is the whole process of the matlab filter!)
