scalogram

1.In complicated frequency components domain, wavelet scalogram and assigned wavelet scalogram were used to further analyze vibration signals.

在频率成分较复杂的地方，利用小波尺度图和分配小波尺度图化分析。

2.Results show that reassigned wavelet scalogram has higher time-frequency resolution than wavelet scalogram and can well identify such close low-frequency components.

结果表明，分配小波尺度图有的时频分辨率，可以清楚地识别出频率成分接近的低频分量；
