水氡与气氡动态的对比分析

COMPARATIVE ANALYSIS ON THE DYNAMIC STATE OF WATER RADON AND GAS RADON

摘要: 首先介绍了模拟和数字化方法观测地下水氡浓度所使用的仪器及其工作原理, 然后对昌黎井、怀来4号井和矾山井的模拟(水氡)和数字(气氡)资料动态特征进行了对比分析。分析认为仪器工作原理和观测步骤基本相同, 但采样(集气)环节有所不同。模拟方法是取一定量的水样, 人工采集水样中的气体, 然后观测;数字化方法是自流井(泉)的水流经脱气装置自动采集气体, 气体样品自动进入观测装置。取样方法的不同, 对观测资料的短周期变化特征有影响, 但两者的趋势变化特征基本一致。

Abstract: The instrument and its working principle used in analogue and digital observation of radon are introduced, and the dynamic characteristics of digital radon data for Changli Well, Huailai 4th Well and Fanshan Well are analyzed in comparison with analogue data.The analysis shows that the work principle and observation steps of the two kind instruments are basically the same, but there are some differences in the sampling course (collecting gas).The gas sampling in analogue observation is performed artificially, but it is performed automatically by the instrument in digital observation.The difference in gas sampling affects the short cycle characteristics of the data, but their tendency are basically consistent.
