摘　　要：G882光泵磁力仪主要用于海洋磁探作业,也常常作为地磁日变观测仪器使用。无论哪种工作需要,使用前都应对仪器稳定性测试,借此了解仪器性能和工作指标。依据相关技术规范和计算方法,结合多年野外日变实测资料,可对该型磁力仪基本性能指标的静态噪声进行计算检验与统计,同时分析环境、数据来源等外部因素对计算结果的影响程度,综合评价此项性能指标限值的合理性。The G - 882 optical-pump magnetometer is mainly used for surveying marine geomagnetic and observing geomagnetic diurnal variation.In this paper,according to technical manual and methods of calculation, the observing data of geomagnetic diurnal variation in many years is used as the basic performance index for the magnetometer.The external factors,such as environment and data sources,which can influence on the calculation result are analyzed, which is basing on the years field diurnal variation observing data, can be used to the basic performance index for this model magnetometer. The rationality of performance index limiting value is also synthetically evaluated.
