洛夫数和地球模型的关系

RELATION BETWEEN THE LOVE NUMBERS AND THE EARTH MODLES

本文采用球对称的地球内部结构模型,按照Molodensky的理论公式计算了2至30阶的静态洛夫数。一共选用了5个地球模型(它们分别是1066A, 1066B, C2,PEM-C和PEM-A),计算结果列于表1和表2中。本文着重讨论了地球模型的弹性参数改变对二阶洛夫数的影响,计算结果分别列于表3—8,并绘于图1—2中。本文所得结论为类地行星洛夫数的计算提供了借鉴。

Using an Earth model with the structure of spherical symmetry, we can calculate the static Love numbers from order 2 to 30 according to Molodensky＇s theory. In calculation five Earth models(1066A, 1066B, C2, PEM-C, and PEM-A)are adopted, and the results can be found in tables 1-2. The major purpose of this study is to explore how the physical parameters of the Earth models influence the value of the second-order Love numbers. The obtained results are given in Tables 3—8, and illustrated by Figures 1—2. The conclusions in this article can be used for reference in the calculation of the Love numbers for the terres-trial planets.
