对采集到的振动信号进行EMD分解，得到一系列频率不同的经验模态函数IMF分量，可以用来滤波和提取原信号的特征。-The collected vibration signals of EMD, get a series of different frequency components of IMF empirical mode function can be used to filter and extract features of the original signal.

经验模态分析（EMD）的MATLAB计算算法，经验模态分析是机械振动分析领域的重要方法-matlabAn Unforgettable ChallengeWhen I was ten years old, I began to chat with foreigners. But I was very shy. Gradually, I became more and more confident with foreig.
