Starting from partial differential equations with respect to displacement components ux、 uy and uz in anisotropic media including 21 elastic parameters,We derived partial differential equations of. seismic wavefronts for qP、、qSV and qSH waves,by using Plane wave motion solution,and discussed the partial differential equations.in spedcial-type anisotropic media(such as transversely isotropic media,ellipitical anisotropic media and cubic anisotropic media).The results obtained lay a solid foundation for understanding the law of the seismic propagation in anisotropic media and for undertaking the forward modelling and inverse comgutation.
