摘　　要：通过对宁德一号井水氡观测历史资料的整理和分析,发现水氡观测资料年动态变化总体呈夏低冬高的趋势,常年水样温度在22.2℃左右。氡浓度测值与水样鼓泡水温之间关系明显,可见该井的氡浓度测值明显受鼓泡水温影响,为了进一步分析水样鼓泡水温的变化对观测水氡测值的影响,通过控制相同的水样在不同水温条件下对氡浓度测值影响的系列实验,试图找出相对于对水氡测值影响较小,较为稳定水样温度或温度区间条件下进行恒温脱气的观测方法。Through the collation and analysis of the historical data of water radon observation in Ningde No.1 well,it is found that the annual dynamic change of water radon observation data is generally low in summer and high in winter,and the perennial water sample temperature is about 22.2℃.The relationship between the radon concentration measurement and the water temperature of the water sample bubble is obvious.It can be seen that the radon concentration measurement of the well is obviously affected by the bubbling water temperature.In order to further analyze the impact of the change of the water temperature of the water sample bubbling on the observation of the water radon measurement,a series of experiments to control the impact of the same water sample on the radon concentration measurement under different water temperature conditions,we try to find out the observation method of constant temperature degassing under relatively stable water sample temperature or temperature range conditions with little impact on the water radon measurement.
