它是固体潮汐研究的基本理论问题 ，也是潮汐观测分析与研究工作的基础。

It is not only a basic theoretical problem of the study of solid tides, but also the foundation of observation and analysis of tides.

并对进一步利用重力潮汐观测研究地球物理问题进行了讨论。

The study of the geophysics using tidal gravity measurements is also discussed in the paper.

介绍了潮汐观测的方法、最新成果以及南极验潮的进展；

The methods and the latest outcomes of tide surveying are introduced as well as the present conditions at Zhongshan Station, East Antarctic.

根据地球自由核章动在周日重力潮汐观测中的共振效应确定了自由核章动的复本征周期和品质因子Q 值，研究了极移重力效应；

The complex eigen period period and Q value of the FCN are evaluated based on the resonance observed in the diurnal tidal gravity, the gravity change due to the polar motion is also studied.
