辽阳FD-105K与FD-125水氡观测仪对比分析研究

Comparative Analysis and Study on FD-105K and FD-125 for Radon Observation of Groundwater in Liaoyang

通过对辽阳地震台汤河冷泉2014年4月以来的两套水氡观测仪对比观测数据进行分析研究。结果表明两套仪器产出的数据具有长周期趋势上的同步性变化特征,氡值均具有明显夏低冬高的年变规律,月均值相关性参数计算也表明两套数据具有高的相关性,但氡值的数值差却存在比较明显的差异。综合分析认为,FD-125水氡观测仪暂不能完全取代FD-105K水氡观测仪,还需要经过长时间的对比观测才能定论,最好能有震例进行检验。

Comparative analysis and study on FD-105K and FD-125 for Radon observation in groundwater in Liaoyang science April 2004. The results show that the value of Rn both FD-105K and FD-125 had the same trend of the change in long period and tendency. Besides, there had the same rule of annual variation which the value of Radon are higher in winter and lower in summer. The correlation coefficient of monthly mean values of Radon also indicates that the data of the two sets of instrument have the very good relevance. But the difference of the two dates are far from expectation. So we think that the instrument of FD-105K do not completely replaced by FD-125, it’ s need a long time to comparative observation, and it would be nice to have a validation by enough earthquake cases.
