CG-5重力仪的漂移特征

基于实验数据，从静态漂移和动态漂移两个方面对CG-5重力仪的零漂特性进行系统分析。结果发现，CG-5重力仪的零漂值（静态漂移率和动态漂移率）较高，幅值随时间变化逐渐减小，最终趋于稳定；静态漂移率和动态漂移率总体随空间纬度（重力值读数段）增大而减小，但个体差异较大。

Drift Characteristics of CG-5 Gravimeter

This paper analyses the CG-5 gravimeter’s drift characteristics from dynamic and static drift rate bases on large experimental data. Our research shows that the CG-5 gravity meter’s zero drift rate is comprehensively high, its variation magnitude becomes smaller as time goes by, but trends to stable eventually; the dynamic and static drift rates show a general trend of decrease as spatial latitude increases (gravity reading section increase),but with significant individual variations.
