摘　　要：本文通过对成都台重力仪器数据去掉固体潮汐理论值、去掉气温、气压、地下水的干扰因素来讨论重力观测曲线的变化。分析导致重力观测年变异常的因素。Based on the observation data of Chengdu gravity meter,we analyze the observation data by removing the solid theoretical value,the temperature affecting,pressure affecting and the groundwater to discuss the gravity changes.We discuss the cause of gravity anomalies observed change.

关 键 词：固体潮 气象因素 年变异常
