体潮 meaning in English

body tide

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负荷作用下的形变特征，数值计算结果表明，在固体内核中的形变很小，由于在长周期核模本征频率附近的共振，液核中低阶( n 10 )位移随半径的变化非常复杂，当负荷阶数超过10时，地核中的形变和扰动位都很小，地球的响应主要表现为弹性地幔中的径向位移，且随深度增加急剧减弱，地表负荷love数与信号频率的依赖关系很弱，给出了体潮love数计算的一种有效的近似处理方案。
