摘　　要：为了检测GSM-19T质子旋进磁力仪主要技术指标及参数的性能,2019年10月17—21日河北省地震局红山基准台以GSM-19W Overhauser磁力仪为标准仪器,对40台GSM-19T质子旋进磁力仪地磁总强度F,通过同步连续采样观测和仪器差进行了比测,计算其差值和均方差。结果表明,大部分测量仪器与标准仪器具有较好的一致性和稳定性,地磁总强度F均方差和仪器差均较小,各项技术指标参数符合大纲测试要求,测量仪器比测合格,可为基站观测和野外流动观测提供准确可靠的数据和仪器保障;小部分测量仪器有漂移,地磁总强度F均方差稍大。In order to test the parameter performance of main technical indexes of GSM-19T protonprecession magnetometer,this paper takes GSM-19W Overhauser magnetometer as a standard instrument to carry out comparative measurements of 40 sets of GSM-19T proton precession magnetometers at Hongshan Benchmark Seismic Station of Hebei Earthquake Agency by synchronously continuous sampling and observing original and difference data,calculating the root mean square errors and instrument differences from October 17 to 21,2019.The result shows that comparing with the standard instrument,most of the measuring instruments have good consistency and stability with small root mean square deviations and instrument differences;the technical index parameters meet requirements;comparison of measuring instruments is qualified and can provide accurate and reliable data and instrument support for base station observation and mobile field observation.A small part of the measuring instruments drifts with a slightly larger root mean square.Therefore,all the received instruments must be compared,and the instruments that meet the requirements could be selected for observation.
