英文摘要：

Firstly, modern theory and methods for signal analysis and processing, for example the ones in time domain （ including parameter recognition in time - domain, correlation analysis as well as statistical analysis and so on ）, and the ones in frequency - domain （ including Fast Fourier Transform, Power Spectrum Decomposition and Wavelet Transform and so on ） were summed up. Also, their applications to vibration signal analysis of rotating machines were studied, by using the vibration data from the rotor kit. And some practical examples of signal analysis and processing in rotating machines were presented.
