摘要
本文对大地测量应用于地球内部物理研究的几个问题作了评述。大地测量观测到的冰后回升运动是了解地幔非弹性的重要依据；利用大地水准面起伏可验证俯冲带和下地幔处的密度异常分布；对地球近周日摆动频率的检测则对核幔扁率提供了有效的制约条件。

In this paper, a few problems of the application of geodesy to interior physical stu dy of the earth are reviewed. The postglacial rebound obtained by means of geodetic observation is an important basis for understanding the inelasticity of the mantle; Using the undulation of the geoid we can check the density anomaly distribution in the subdu-ction zone and lower mantle; The detection of nearly diurnal wobble frequency of the earth provides constraint for core-mantle flattening.
