摘　　要：将怀来地震台三种数字化气氡观测资料进行分析后,对比不同脱气集气装置、不同井(泉)类型观测方式,观测数据曲线动态变化特征之间的差异性发现:怀4井与矾山泉逸出气氡在较大程度上受脱气集气装置影响大,同时降雨量会影响怀4井气氡观测数据;气温对怀3井土壤气氡观测影响较明显,但存在集气装置老化现象。因此,脱气集气装置的正常与否对于获得真实可靠的观测结果具有重要作用。Through contrast three kinds of digital gas radon observation data analysis,contrast different degassing gas collecting device and different ways of observation Wells(spring)type,observation data curve on the discrepancy between the dynamic change characteristics of discovery:Huailai 4 Well and Fanshan spring are large extent affected by the degassing gas collecting device.At the same time,Rainfall will affect the observed data of radon in Huailai 4 well.Temperature has obvious influence on soil gas radon observation in Huailai 3 well,but the gas collecting device is older.Therefore,The device plays an important role in obtaining true and reliable observation results.
