The cause of the packet energy variation is wave-flow interaction produced by temporal variation of the wind.
能量变化的实质是，风场的时变性引起了波流相互作用。
And also the variation of the wave packet amplitude and energy has been discussed.
此外，还讨论了沿波射线波包振幅和能量的变化。
The wavelet packet method characterized by good time-frequency localization can be used to make signal reconstruction and energy analysis of blasting vibration wave.
利用小波分析良好的时频局部化性质，可以很好地对爆破地震波进行信号重构和能量分析。
