| 摘 要： | 我们根据广义虎克定律导向Ｚ轴对称的各向异性介质的程函方程。基于Ｈｕｙｇｅｎｓ原理和类似于各向同性介质的有限差分法，用波前扩展示求解各向异性介质的程函方程，克服了Ｖｉｄａｌ方法中有违背因果律的不足。理论计算结果充分显示了该方法的快速，灵活，方便的优点。

| Abstract: | According to the generalized Hookels 1aw, we derive the eikonal equation for the anisotropicmedia with z-axis of symmetry. The wave front spreading method has been used to solve theeikonal equation for the anisotropic media on the basis of the Huygens' principle and the methodsimi1ar to the finite-difference method for the isotropic media. It overcomes the defects inviolationof the causal laws in Vidal's method. The theoretical calculation results demonstrate that themethod is fast, flexible, and convenient. |
