小波包分析提取振动信号中的特征频率，通过matlab代码，正确率可以达到98％。( Wavelet packet analysis to extract vibration signal characteristic frequency, By matlab code, Accuracy can reach 98 .)

说明：  产生伪随机噪声的MATLAB程序，在通信系统仿真可以用到(produce pseudo-random noise MATLAB procedures, the communications system simulation can be used)

在科研中，大量时间花在统计年鉴的搜集上，例如找《中国城市统计年鉴》中2000多个市，要对分散的八个城市群找对应的数据，如果每次筛选会花费大量时间，如果做好excel表头，把对应的城市写上去会在多个文件多个工作组查找满足要求的数据，直接按需要保存成excel，进行后续分析。(In the research, the amount of time spent on the Statistical Yearbook of the collection, for example, to find " China City Statistical Yearbook" in more than 2000 cities and want to find a group of eight cities scattered corresponding data, if each screening will spend a lot of time, If you do excel header, the corresponding write up the city will look to meet the requirements of data in multiple files multiple workgroups, saved directly as needed to excel, for subsequent analysis.)
