And the sort separability criterion can also play the role of being a quantification measure on the characteristic extracting of flaw signals.
类别可分性判据对缺陷信号的特征提取也起了定量衡量尺度的作用。
The characteristic frequency band of the fault can be identified by wavelet packet decomposition and its energy spectrum conveniently, and the quantification analysis are then performed.
