摘要
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。
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.
