中文摘要：
黏弹各向异性介质中传播不均匀波，其反射、透射模式不仅与介质分界面两侧速度对比有关，还与品质因子Q的对比有关．用伪谱技术模拟黏弹各向异性介质分界面上波的反射、透射，并与弹性各向异性介质、黏弹各向同性介质和弹性各向同性介质的模拟结果做比较．计算平面波的反射、透射系数，分析介质的黏弹性和各向异性对反射、透射系数的影响．数值模拟了一个三层介质模型中的波场，分析两个分界面上产生的反射波的特征．黏弹各向异性介质中，qS波比qP波衰减程度大．
英文摘要：
The waves propagating in viscoelastic anisotropic media are inhomogeneous. The modes of reflection and transmission are related not only to the velocity contrast, but also to the Q contrast of the correlated media. By modeling reflection and transmission of waves on the interface between viscoelastic anisotropic media using the pseudospectrum method, the results in the elastic anisotropic, viscoelastic isotropic, and elastic isotropic media are compared. Reflection and transmission coefficients are calculated and the effects of viscoelasticity and anisotropy of media on these coefficients are studied. By modeling the wave fields in a three-layer media model, the natures of reflected and transmission waves generated on two interfaces are investigated. In viscoelastic anisotropic media, qS waves have more inclination to attenuate than qP waves.
