| Abstract: | In this paper, the situation of different operation states of Tai’an PET gravimeter is introduced, and the anomaly of the grid is judged by comparison with the very wide band digital seismograph. At the same time, the main interference factors of the observation data are eliminated, and the relative objective gravity observation trend information is extracted. It is found that there is a negative trend drift of the gravity meter in Tai’an seismic station from 2013-09~12 and 2014-02~04. |
