摘　　要：【目的】研究水氡与气氡测项之间关联性及异同。【方法】以宝鸡上王流体台与陇县流体台2015—2020年水氡与气氡连续观测资料为研究对象,分析同台站不同测项、同测项不同台站正常数据资料及异常曲线对比。【结果】结果表明,溶解水氡与气氡无明显的关系。在中强震前,台站地震监测数据无明显前兆异常现象。水氡受人为影响较大,而气氡受集气脱气装置管路堵塞影响较大。上王流体台与陇县流体台溶解水氡年变化趋势上都是典型的夏高冬低形态。而上王BG2015R型气氡仪记录到的气氡年变形态则表现为夏低冬高形态,陇县SD-3A气氡仪记录到的气氡年变形态不是很明显。【结论】目前还无法用一个有效的物理量建立溶解水氡与气氡之间的关系,溶解水氡与气氡无明显的关系。[Purposes]This paper aims to study the correlation,similarities and differences between water radon and gas radon measurements.[Methods]Taking the continuous observation data of water and gas radon from Baoji Shangwang Fluid Station and Longxian Fluid Station from 2015 to 2020 as the research object,this study analyzes the comparison between normal data and abnormal curves of different observation items in the same station and the same observation items stations in different stations.[Findings]The results show that here is no obvious relationship between dissolved water radon and gas radon.Before moderate to strong earthquakes,there were no obvious precursor anomalies in the seismic monitoring data of the station.Water radon is greatly af-fected by human activities,while gas radon is greatly affected by pipeline blockage in gas gathering and degas-sing devices.The annual variation trend of dissolved water radon in the Shangwang and Longxian fluid stations is typical of high in summer and low in winter.The annual deformation of gas radon recorded by the Shangwang BG2015R gas radon instrument shows a low summer and high winter shape,while the annual deformation of gas radon recorded by the Longxian SD-3A gas radon instrument is not very obvious.[Conclusions]At present,it is not possible to establish a relationship between dissolved water radon and gas radon using an effective physical quantity,and there is no obvious relationship between dissolved water radon and gas radon.
