| 摘 要： | 讨论了上地幔各向异性介质中的潮汐运动方程，根据Deiewonski提供的地球模型参数，利用经典的Runge－Kutta数值积分方法，计算了固体潮勒夫数和负荷勒夫数．结果表明，考虑上地幔介质各向异性与否对固体潮勒夫数的影响较小（约为0．06％），而对负荷勒夫数的影响较大（2．5％），进一步说明了中低阶负荷勒大数对上地慢介质特性的敏感性．

| Abstract: | The tidal inchon equations of the Earth for the anisoropic medium in uppermantle are discussed. Based on the Earth parameters of the isotropic and anisotropicmedium given by Dziewonski, the Love numbers and load Love numbers arecalculated using a classical Runge-Kutta numerical intogration method. The resultsdemonstrate that the influence of the anisotropic meditun in uPPer mantle on the Lovenumbers is very small （0.06%）, but relatively large on the load Love numbers （2.5%）.The results show simultaneously that the load Love numbers with lower and middleorder are sensitive to the characterishcs of the upper mantle medium. |
