摘要
In this paper, by solving seismic wave equation the attenuation coefficient formula in dual-phase medium was derived, and the change relationship of the attenuation coefficient with frequency was analyzed, the results show that when seismic wave propagated in the frequency range of conventional seismic exploration in dual-phase medium, the medium absorption effect existed, and the attenuation coefficient was approximately proportional to circular frequency. hemas-microsoft-com:office:office" />
