CG-5重力仪零漂稳定性评估

对4台购于不同时期的CG-5重力仪进行零漂稳定性分析，提出运用拟合直线相关系数来评估仪器的静态零漂稳定性，以及运用平均动态零漂率来评估仪器的动态零漂稳定性。数据处理结果证明，该方法能有效地评估CG-5重力仪的零漂稳定性特征。

Elevation on Zero Drift Stability of CG-5 Gravimeter

Zero drift stability is an important performance parameter of the CG-5 gravimeter, determining the accuracy of the instrument to a great extent. The zero drift stability can be divided into static zero drift stability and dynamic zero drift stability. Based on the zero drift stability analysis of four CG-5 gravimeters purchased at different times, we evaluate the static zero drift stability of CG-5 gravimeter using the correlation coefficient of the fitted linear, and evaluate the dynamic zero drift stability of CG-5 gravimeter using average dynamic zero drift rate. The experimental results show that the method can effectively evaluate the zero drift stability of the CG-5 gravity meter.
