中文说明：2009年yAN构造出的新方法，非常有效的信号时频分析方法。 其通过对频域内的信号的不同频率段进行分段求解，可以很方便的提取出如故障信号的信号特征。减少了不同频率下的干扰，非常快速的对信号进行分析。
English Description：
2009 yAN constructed out of new methods, very effective signal time-frequency analysis method. The signal in the frequency domain solution of different frequency bands can be segmented, you can easily extract the fault signal signal characteristics. Reducing the interference of different frequencies, very quick to analyze the signals.
