摘要
对地震波衰减的研究经过近五十年的发展已经取得了不少进展.本文简述了地震波的衰减机制、有关衰减的基本理论以及影响地震波衰减的主要因素,重点概括了地震波衰减的反演方法,最后预测了地震衰减研究的发展趋势.
A great progress has been made in research on seismic attenuation over fifty years of development. In this paper, it summarizes attenuation principle of seismic wave, general theories on attenuation and main factors that affect seismic attenuation. The methods of inversion on seismic attenuation are emphasized. At last, the development tendency on research of seismic attenuation is forcasted.
