摘要
本文通过传播矩阵法,确定地震波在横向各向同性介质中传播的水平慢度垂直慢度,进而用解析式给出入射角、透射角、转换角及折射角。
By the use of propagating matrix method, horizontal and vertical slowness of seismic wave in 2─D transversely isotrpic medium(TIM) are determinated,furthermore,analytic solutions to its incidence,transmission, conversion and refraction angles are presented.
