  1. The numerical results indicate that the deformation within the solid inner core is very small. however, in the fluid outer core, the changes of the displacement with relatively low spherical harmonic degree ( n < 10 ) is very complicated via the radius, due to the resonance near the eigenfrequenies of the core long - period oscillations. while the spherical harmonic degree of the loading is larger than 10, the deformation and the gravitational perturbation in the core are very small, and the earth ' s deformation response is dominantly represented as the radial displacement in the elastic mantle

    研究了地球在日月引潮力和表面負荷作用下的形變特徵,數值計算結果表明,在固體內核中的形變很小,由於在長周期核模本徵頻率附近的共振,液核中低階( n 10 )位移隨半徑的變化非常復雜,當負荷階數超過10時,地核中的形變和擾動位都很小,地球的響應主要表現為彈性地幔中的徑向位移,且隨深度增加急劇減弱,地表負荷love數與信號頻率的依賴關系很弱,給出了體潮love數計算的一種有效的近似處理方案。
