十字形CFAR检测方法，可以处理一些特殊的目标回波，得到距离多普勒图(Cross CFAR detection method that can handle some special target echo obtained from the Doppler diagram)

包络分析大多在原始振动加速度信号基础上进行， 受噪声干扰等因素的影响较大 通过对原始振动信号自相关函数作包络分析， 可以有效地抑制噪声， 突出反映故障调制特征(s． Most of the envelope analyses are based on original vibration accelera- tion signal，which is seriously influenced by noise interference． The noise is effectively suppressed by envelop analysis of auto correlation function of original vibration signal，and the modulation characteristics of fault are highlighted．)

在matlab上实现各自函数傅立叶变换的小程序，仅供参考。(In matlab to achieve their respective functions Fourier transform applet for reference only.)

MATLAB编写的ode45求解转子系统动力学程序，可用于计算响应和临界转速，程序正常可运行，主程序和函数放在同一个txt文件中。(Ode45 program written in MATLAB for solving rotor system dynamics can be used to calculate response and critical speed. The program can run normally. The main program and function are in the same TXT file.)

matlab 做图像平移和旋转 用的是领域插值法 二次线性插值 另外还有一些调用matlab自带函数的编程(matlba image shift and rotate)

计算两个区域的相关系数的平均值 速度比直接用regress函数 快很多很多(calculate the mean correlation coefficient of two areas)
