The energyattenuation formula has the following features: (1) The larger Q is, the more slowly the energy attenuates;
能量衰减公式具有下列性质：（1）Q值越大，能量衰减得越慢；
2
The existence of various lacunas in bolt bonding system will cause the acoustic wave energyattenuation, phase aberration and frequency dispersion.
由于锚固体系中有不同大小和程度的缺陷，声波在传播过程中将产生能量衰减、相位突变及频散现象。

In this paper, we discussed the underwater sound reverberation of moving medium, which is a non-stationary stochastic process even after compensating its energyattenuation.
