摘要
把地球表面潮汐形变问题扩展到地球内部.定义了Love函数和几种潮汐形变因子,并对两个实际地球模型(1066A和PREM)进行数值计算和讨论,以了解地球内部的潮汐形变特征,专门讨论了Love函数导数以及应力固体潮张量的计算问题.本工作对了解全地球潮汐场以及潮汐触发地震等问题将有所帮助.
The problem of surface tidal deformation of the earth is expanded to that in the interior of the earth. Love functions and some tidal deformation factors are defined and calculated for two earth models (1066A and PREM), so that the tidal deformation characteristics in the interior of the earth are understood. The calculating problems of the derivatives of Love functions and the tidal stress tensor are discussed specially. The present work is helpful for understanding the global tidal field as well as the triggering of earthquakes.
