摘要
介绍了银川地震臼重力观测情况。应用调和分析、潮汐变化、非潮汐变化及滤波等分析方法，对银川台GS15-NO215型重力仪2003～2007年的观测资料进行了处理，分析了银川台数字化重力资料的观测质量及年变周期的特点。总结了银川台重力数字化资料与周边地区地震活动的对应关系及其映震情况。
We introduced the observation situation of gravity in Yinchuan station. We used some analysis methods of harmonic analysis, tide change, non-tide change and filter and so on to process the observation data of GS15-N0215 gravimeter from 2003 to 2007 in Yinchuan station. And we analyzed the characteristic of observation quality and annual variation period of Yinchuan station. At last, we summarized the corresponding relation and correspo between digital gravity data in Yinchuan station and seismic activity in its periphe tal gravity data in nding earthquakes ral areas.
