Popis:	The long period tidal gravity observations recorded with a superconducting gravimeter at station Wuhan/China from 1 January 1986 to 31 December 1994 (old series) and from 20 December 1997 to 30 April 2000 (new series) are studied comprehensively. The new tidal amplitude factors and phase differences are determined precisely using modern international standard data processing techniques. The tidal gravity signals due to the geophysical sources as of global ocean tides and local atmospheric pressure are comparatively studied. The dynamic influences of the Earth's core, i.e. the resonance parameters (eigenperiod, quality factor and resonance strength) of the free core nutation, are determined and the corresponding results are compared with those obtained in the previous studies.
