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. )

分别对正弦波，三角波，方波，一周期内取为整数的64个点（A=4095）；写锯齿波和方波的谐波构成（只写了3、4个）。(Of sine wave, triangle wave, square wave, A week off for integer in the period of 64 points (A = 4095) Write a sawtooth wave and square wave of harmonic (only wrote 3, 4).)

关于飞行器制导控制方面比较全面的仿真源代码，其中包括飞行器三自由度和六自由度仿真，单次仿真和蒙特卡洛仿真，EKF算法和UKF算法仿真等等。(On aircraft guidance control more comprehensive simulation source code, including aircraft and six degrees of freedom simulation of three degrees of freedom, a single simulation and Monte Carlo simulation, EKF and UKF algorithm simulation algorithms and so on.)
