| 摘 要： | 负荷潮汐改正与地壳上地幔结构有密切关系,主要原因是负荷潮汐取决于高阶勒夫数。利用较新的1066A地球模型,对负荷勒夫数进行了重新推算,并依据负荷勒夫数组成重力、倾斜、应变及位移格林函数。发现在近区用1066A模型和经典的G-B模型求出的格林函数值差别较大。据此,推估出不同地球模型对负荷潮汐改正的影响,其中远区估算按解析方法进行,近区由数值法进行。

| Abstract: | There is close relation between loading tidal correction and structure of crust and upper mantle. By using recent 1066A earth model, we have recalculated the loading love numbers and obtained loading Green's functions for gravity, tilt and strain. It is shown that there are considerable difference of Green's function obtained by these two models, especially for small ψ. Afterwards, we have estimated the effect of different model on loading correction, in which the evaluation of distant region is carried out by analytical method, and for near region, by using digital method. |
