Abstract
As signals of short time non-stationary were often hidden in the course of long time stationary signal, the processing was neglected frequently and the whole signal analyzing was limited. In order to solve the problem, short time fourier transform was introduced to deal with local data in the paper. High time-frequency resolution was got by this method, which offered a way to analyze the characters of vibration signal.关键词
