摘　　要：以怀来后郝窑地震台怀4井ATG-6138M型气汞仪为研究对象,分析及排除其观测干扰因素,为正确识别震前异常信息提供参考依据;对ATG-6138M型气汞仪和DFG-B型气汞仪进行观测质量对比评价,运用origin数据统计软件进行数据分析。研究表明:ATG-6138M型气汞仪数据变化较为灵敏,且观测质量优于DFG-B型气汞仪,同时发现怀4井气汞浓度主要受到观测室温度和动水位的影响。Taking the ATG-6138M vapormeter of Huailai No.4 Well in Houhaoyao seismic station as the research object,we analyzed and excluded the interference factors of its observation,and provided a reference for correctly identifying the pre-earthquake anomaly information.The observation quality of ATG-6138M vapormeter and the DFGB vapormeter are contrastively analyzed using origin data statistical software.The result shows that:data changes of the ATG-6138M vapormeter are more sensitive and its observation quality is better than that of the DFG-B vapormeter.At the same time,it is found that the concentration of gas mercury in Huailai No.4Well is mainly affected by the temperature of observation room and dynamic level in well.
