| 摘 要： | 2014年山西定襄七岩泉新增BHC-336智能定标器,对新、旧2套测氡仪的水氡测值,就稳定性、数据一致性、内在质量等进行对比分析,结果显示,因存在系统误差,2台测氡仪水氡测值稳定性均值存在差异,测量精度和性能具有一致性;与新测氡仪相比,旧测氡仪水氡测值相对偏差和均值标准误差更小,精度更高,数据相关程度较高,数据稳定性更好。定襄水氡对华北5级以上地震具有较好的映震能力,新测氡仪对2016年4月7日原平4.6级地震映震效能比旧测氡仪灵敏。

| Abstract: | The BHC-336 intelligent calibrator was added to Qiyan Spring in Dingxiang, Shanxi Province in 2014. The stability, data consistency and intrinsic quality of water radon with two new and old radon measurements are compared and analyzed. The results show that due to systematic errors, the stability mean values of radon in water measured by two radon meters are different, and the measurement accuracy and performance are consistent. Compared with the new radon measurements, the relative deviation and mean standard errors of the old measuring instrument are smaller with higher precision, higher data correlation, and better data stability. The water radon in Dingxiang has better seismic reflection efficiency for earthquakes with magnitude 5 or above in North China. The new radon measurements are more sensitive than that for the old one for the seismic reflection performance of the Yuanping M 4.6 earthquake on April 7, 2016. |
