| 摘 要： | 本文研究了液核地球对日月引潮力位球谐函数项的变形响应,即周日固体潮。作为数值结果,计算了1066A地球模型的周日潮汐勒夫数。所建立的周日固体潮理论模型改进了Molodensky液核动力学理论模型。为了比较两者之间的差异,还根据Molodensky理论模型计算了1066A地球模型的周日潮汐勒夫数。

| Abstract: | Precise observations of the Earth tides have confirmed that the diurnal tidal Love numbers iare.frequency-dependent.This can be explained by the liquid-core dynamical theory.The purpose of this paper is to numerically study the dynamical effects of a elliptically stratified And rotating fluid core upon the diurnal Earth tides In our model two toroisalmodes and one spheroidal mode are included to expreses displacement in the liquid core.Moreover,the Adamas Williamson condition which is necessary in MoIodensky theory is not assumed.We have obtained the diurnal tidal Love numbers for 1066-A earth model by solving the boundary value problem.Comparision with Molodensky model 1 shows that the agreement is quite good except wave ψ1,which probably results from the difference between resonant frequencies. |
