摘　　要：选择测汞历史较长的云南洱源台温泉井,利用2套ATL-2000型测汞仪与XG-4型测汞仪进行对比观测实验。结果表明:3套仪器观测精度一致,但本底值不一致;ATL-2000型测汞仪测值整体低于XG-4型测汞仪,且测值相差大,观测数据变化趋势一致性差,相关性很弱;2套ATL-2000型测汞仪相关性好,但均值不一致,相差50.09 ng/L。分析认为,ATL-2000型测汞仪目前尚不能替代现阶段地震监测中常用的测汞仪。Select the Eryuan hot spring well in Yunnan with a long history of mercury measurement,and conduct comparative observation experiments using two sets of ATL-2000 mercury meters and XG-4 mercury meters.The experimental results show that the observation accuracy of the three instruments is consistent,but the background values are not consistent;The overall measured values of ATL-2000 mercury analyzer are lower than those of XG-4 mercury analyzer,and the difference in measured values is significant.The consistency of observed data trends is poor,and the correlation is weak.Two sets of ATL-2000 mercury measuring instruments have good correlation,but the mean values are inconsistent,with a difference of 50.09 ng/L.Analysis suggests that the ATL-2000 mercury meter is currently unable to replace the commonly used mercury meters in earthquake monitoring.
