| Abstract: | In the paper, we discribed the constructure and operation properties of GS15-227 and ET-22 gravimeters and also computed the observation data of the two meters from 1987 to 1992 at Xiaguan and Lijiang station, Yunnan Province, with Nabal processing and Venedikov harmonic methods. Consequently the optimal tidal parameters, the tidal and non-tidal dynamical background were determinated after having been flited and corrected. Moreover six-earthquakes were collected and anomaly variation and the activity of earthquakes. Finally we obtained the response characteristics of tidal and non-tidal signals to earthquakes in the area. |
