公司用于ＣＭＭ３级实施培训的教程，对于提高ＣＭＭ３级实施水平的提高有较好的帮助.(CMM3 class companies for the implementation of training curricula, improve CMM3 level for the implementation level have better help.)

在vb中初学者很容易搞混的“0”，“Null”，“Empty”，“Nothing”之间的区别-In vb beginners easily confused in the

说明：  function C=capacity(SNR,Nt,Nr) %SNR=0; %定义信噪比为0HZ A=10^(SNR/10); %信噪比的单位转换关系式 Im=eye(min(Nr,Nt)); %这里的"1"为发射天线和接收天线两者数目少的根数 sum=0; %初始化sum为0 for i=1:10000 %程序循环10000次 H=randn(Nr,Nt); %产生高斯信号源 if Nr<Nt Q=H*H'; %求威沙特矩阵 else Q=H'*H; end sum=sum+log2(det(Im+A*Q/Nt)); %10000次循环得到的信道容量总和 end C=sum/10000 %10000次循环的平均值(function C=capacity(SNR,Nt,Nr) %SNR = 0;% defines SNR as 0Hz A = 10 ^ (SNR / 10);% s / N unit conversion relation Im = eye (min (NR, NT));% here "1" is the number of the less number of transmitting antenna and receiving antenna Sum = 0;% initialize sum to 0 For I = 1:10000% program cycles 10000 times H = randn (NR, NT);% produces Gaussian signal source if Nr<Nt Q = h * H ';% to find the weissard matrix else Q=H'*H; End Sum = sum + log2 (DET (IM + A * q / NT));% sum of channel capacity from 10000 cycles End C = sum / 10000% average of 10000 cycles)

利用粒子群优化算法进行大地电磁视电阻率反演(Inversion of magnetotelluric apparent resistivity using particle swarm optimization algorithm)

flash+xml焦点图代码，切换时有动态模糊效果，并且可自定义图片大小，链接还有文字背景色等(Flash + XML focus map code, switching has dynamic blur effect, and can customize the size of the picture, links and text background color, etc.)

基于simulink的交流电机三相交交变频调速系统，具有良好的仿真波形(Based on simulink AC motor three-phase AC variable frequency speed control system, with a good simulation waveform)

说明：  查找一维信号中的波峰和波谷，自定义窗宽和阈值，可应用于脉搏波峰值查找之类的(Matlab looks for one-dimensional signal peaks and troughs, variable parameters are threshold, search type and window width)

用来判断 硬件设计是否良好的规则, 让不懂硬件的人 对硬件的布置有所了解.-used to judge whether good hardware design rules, let the people do not understand the hardware right hardware layout understand.
