At last, we recomposed some frequencybandof wavelets, and the results can efficiently extract the features of acoustic emission signal.
最后通过对能反映源特征的频带信号进行重构，这样能更好更有效的提取声发射信号的本质特征。

Spontaneous emission can be totally suppressed or strongly enhanced depending on the relative position of the resonant frequency from the edge of the photonic band gap and the photonic mode density.
