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. )

运用FDTD法，使用C语言计算二维TM波时谐场相位人图的程序.(Using FDTD method, using the C language to calculate the two-dimensional TM wave the harmonic field phase program.)

绘图函数用mcc生成的代码嵌入VC工程实例，Win32 Console版本(mapping function using mcc generated code embedded VC engineering example, Win32 Console Version)

vc++下各种数字滤波器的实验程序，包括带通，带阻，低通，高通。(vc++ a variety of digital filters under the experimental procedures, including band-pass, band stop, low-pass, high pass.)

在MATLAB下的一个对基带信号的采样变频至中频。GSM基站的接收频段为890～915 MHz。(A baseband signal sampling frequency to frequency under MATLAB. Receiving frequency band GSM base station is 890 ~ 915 MHz.)

vit程序清晰简单，容易阅读，matlab调用易实现(vit procedures clear and straightforward, easy to read, matlab call easy to realize)

说明：  递归，是函数实现的一个很重要的环节，很多程序中都或多或少的使用了递归函数。递归的意思就是函数自己调用自己本身，或者在自己函数调用的下级函数中调用自己。 递归之所以能实现，是因为函数的每个执行过程都在栈中有自己的形参和局部变量的拷贝，这些拷贝和函数的其他执行过程毫不相干。这种机制是当代大多数程序设计语言实现子程序结构的基础，是使得递归成为可能。(Recursion, is a function to achieve a very important part of many programs are more or less use the recursive function. Recursive mean that the function of its own call to themselves or subordinates in their own function calls a function to call their own. Recursion that can be achieved because the function of each execution in the stack has its own shape parameters and local variables of the copy, the copy and the implementation process has nothing to do other functions. This mechanism is the most modern programming language implementation subroutine structure of the foundation is to make recursion possible.)

遗传算法的源程序，基于matlab，对于毕业设计会起到很大的作用；(Genetic algorithm source code, based on matlab, will play a big role for a graduation project )

MIMO虚拟技术信道容量随信噪比的变化关系图像，MATLAB仿真程序，源代码(Virtual MIMO channel capacity with the signal-to-noise ratio of the change in the relationship between image, MATLAB simulation program, the source code)

说明：  文章编辑系统，输入一页文字，程序可以统计出文字、数字、空格的个数。 静态存储一页文章，每行最多不超过80个字符，共N行 (Article editing system, input a word, the program can be worked out, words, numbers, the number of spaces. Static storage an article, each line no more than 80 characters, a total of N rows)
