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. )

描述了Particl Filter的基本原理，以及它与EKF的区别；并用PF实现了对自由落体的跟踪效果仿真。(This program describe basic principle of partilc fitler and its difference with EKF. It also realizes tracking simulation of free fall ball.)

剔除了bug完全可编译运行，是分析guider 滤波，设计其他平台如FPGA等算法的很好的参考。(Excluding the bug can be compiled to run fully, is to analyze the guider filter, designed for other platforms such as FPGA algorithms such as a good reference.)

2fsk的调制与解调，matlab编写，绝对正确。(2fsk modulation and demodulation, matlab prepared, absolutely correct.)
