摘　　要：红山基准地震台作为全国地震监测专业设备的比测台站,多次承担地震观测仪器的比测工作。2021年11月23日,以该比测站GSM-90F Overhauser磁力仪作为标准仪器,基于数据一致性、差值均方差和仪器差等,对16台EREV-C质子旋进磁力仪性能进行测试检验。测试结果显示,该质子旋进磁力仪与标准仪器具有较好的一致性,地磁场总强度F值均方差<0.10 nT、仪器差≤±0.50 nT,各项指标均满足测试要求,表明该磁力仪性能稳定、精度高,可用于地震台站常规观测以及磁测和探矿等工作。As a comparison station for professional seismic monitoring equipment in China,the Hongshan Benchmark Seismic Station has undertaken multiple comparisons of seismic observation instruments.On November 23,2021,the GSM-90F Overhauser magnetometer was used as a standard instrument to test the performance of 16 EREV-C proton precession magnetometers based on data consistency,mean square deviation of difference,and instrument difference.The test results show that the proton precession magnetometers have good consistency with the standard instrument.The mean square deviation of the total geomagnetic field intensity F value is less than 0.10 nT,and the instrument difference is less than±0.50 nT.All indicators meet the test requirements,indicating that the magnetometers have stable performance and high accuracy,and can be used for routine observation,magnetic survey,and mineral explorationat seismic stations.
