| 摘 要： | 2011年4月18日开始,银川地震台小口子重力观测出现毛刺、抖动等变化,通过对观测环境、观测线路、观测仪器的排查,最终排除了由于观测信号线故障所导致的变化,有效地解决了观测中出现的复杂问题,加深了观测人员、分析人员对前兆观测异常的判断与认识。

| Abstract: | From Apr.18,2001,the curves of gravity observation in Yinchuan seismic station（Xiaokouzi） appeared abnormal variation.The observation environment,the wire routes and the instruments were checked carefully and fixed a breakdown,solved the problems in the observation,and improved the observers of precursory anomaly judgment and cognition. |
