说明：  在混合高斯背景模型中，认为像素之间的颜色信息互不相关，对各像素点的处理都是相互独立的。对于视频图像中的每一个像素点，其值在序列图像中的变化可看作是不断产生像素值的随机过程，即用高斯分布来描述每个像素点的颜色呈现规律单模态(单峰)，多模态(多峰)(Gaussian mixture background modeling is a background representation method based on the statistical information of pixel samples. Statistical information such as the number of patterns, the mean and standard deviation of each pattern are used to represent the background. Statistical difference (such as 3_principle) is used to judge the target pixel. Complex dynamic background modeling has a large amount of computation. In the Gaussian mixture background model, it is considered that the color information between pixels is uncorrelated and the processing of each pixel is independent of each other. For each pixel in a video image, the change of its value in a sequential image can be seen as a random process that produces pixel values continuously, i.e. Gaussian distribution is used to describe the regularity of color rendering of each pixel in single mode (single peak) and multi-mode (multi-peak))

说明：  将wav格式音乐文件导入，便可对其进行简单控制应用操作，如 播放与暂停，循环播放，切换下一首歌曲功能，所使用机器为4位机，用最为简陋的芯片也实现8086与51的功能。(By importing the wav format music file, we can simply control its application operation, such as playback and pause, circular playback, switching the next song function. The machine used is 4-bit computer, and the function of 8086 and 51 is also realized with the most rudimentary chip.)

vb在线歌曲播放器编写实现，可能网址失效了，这个下载后自己修正下，内核对于VB新手有学习价值。

说明：  可以计算声学互阻抗，广泛应用于吸声、超材料的研究(Calculate acoustic impedance)

说明：  二型模糊方面的一篇论文，里面有降型过程的分类和代码(A paper on type II fuzziness, which contains the classification and code of the type reduction process)

全国电子设计大赛相关的需要注意的培训内容！这是２００７年我们老师给我们讲的一些东西！-National Electronic Design Contest-related training need to pay attention! This is a teacher in 2007 told us something!

这个是51单片机4*4扫描的C程序。欢迎大家下载、试用。谢谢大家的支持！

本文对16QAM解调软信息输出(LLR)理论计算方法进行分析，推导 出其简化解调算法。将两者在性能和计算复杂度方面进行了分析比较，并分别在 高斯白噪声信道和瑞利衰落信道环境下进行仿真(In this paper, 16QAM demodulator soft information output (LLR) theoretical calculation method for the analysis derived simplified demodulation algorithm. Both in performance and computational complexity aspects are analyzed and compared, and in white Gaussian noise channel and Rayleigh fading channel simulation environment)
