摘要 本文从目前普遍为油气地球物理工作者所承认的Hudson本构方程出发,分析讨论了含流体、气体裂隙各向导性介质中地震波相速度和横波双折射特性。这些工作可以加深和提高地震波在含流体和气体裂隙各向异性介质中传播规律的认识。 Based on the Hudson's constitutive equation which is universally accepted by geophysicists nowadays, the phase velocity of seismic wave and S-wave birefringence in anisotropic media containing gas or fluid filled fissures are discussed. This study mny help us get a deeper understanding on thc regular pattern of seismic wave propagation in such media.
