| 摘 要： | 本文详细回顾了克利斯托费尔方程(Christoffel)的推导.在此基础上,提炼出时空域和频率域克利斯托费尔方程,前者可作正演计算介质的相速度,后者可计算介质的群速度.并计算了横观各向同性介质的相速度和群速度.最后对无损耗各向异性介质的相速度和群速度的关系进行了简单讨论.

| Abstract: | The paper look back on the calculation of christoffel's equation, whose T-S domain and F-K domain are refrined in this paper. The T-S equation and the F-K equation can be used in calculating phase velocity and grroup velocity separatelly. Velocity is aniimportant and basic parameterr in reseaching of anisotropic media. Christoffel's equation is a useful an efficient method in this work, and it is suitable for want only media including anisotropy. We calculate phase and group velocity of transverse isotropic media with the aid of this equation. Finally, the relationship of phase velocity and group velocity is explained in the paper. |
