It is showed by theoretical study and tests that existing fluid in porous medium and its movements are main reasons of dispersion and attenuation of elastic waves.
理论研究和实验表明，多孔隙介质中流体的存在及其运动是弹性波频散和衰减的主要原因。
In this paper, I present three studies on high-frequency seismic attenuation and propose that the physical mechanism results from the interference of elastic microscopic multiple scattering waves.
通常认为地震波高频衰减的物理机制主要是滞弹性的吸收，本文通过如下三方面的研究认为地震波高频衰减的物理机制主要是弹性的微观多次散射波的相互干涉。
