说明：  格子玻尔兹曼方程基于格子Boltzmann方法开源可视化软件的源代码(The source code of open source visualization software based on lattice Boltzmann method has high practical value.)

HTML5 CSS3风力发电车，风车动画，本代码中演示了两种风车的实现方法，一是使用CSS3+风车图片的方法，也就是用CSS3形成动画效果，风车只是调用了图片，二种方法是纯CSS3来实现风车和动画效果，这是大家借鉴的重点。

日志工具log4j的示例代码，并且有log4j.properties配置详解。

说明：  自己写的拼图游戏，vs2008，附带音乐和鼠标点击音乐(Write your own jigsaw puzzle, vs2008, incidental music and music mouse clicks)

由给定的多项式生成扩域-given by the generating polynomial expansion Domain

用Matlab程序实现非均匀有理B样条，程序简单，容易理解(nou-uniform rational B-spline)

构造一组输入为白噪声加三个频率非常接近的正弦波，其信噪比为10dB，观测长度为256。试分别用普通AR谱估计和采用功率噪声抵消算法的AR谱估计估计这组信号的频率，并比较结果。-constructed a group of white noise input plus three very close to the frequency sine wave, the signal-to-noise ratio of 10dB. Observing length of 256. Were used to test the general AR spectral estimation using power and noise canceling algorithm for the estimation of AR spectrum estimation of this group of signal frequency, and the results of the comparison.
