| 摘 要： | 在进行地下流体数字化气氡观测及将观测资料应用于震情分析的过程中 ,发现某些干扰因素对数字化气氡观测和水氡的影响不同。在目前所用观测仪器和方法的条件下 ,气温对气氡值的影响系数为 - 0 4 % /℃ ;气压对气氡测值的影响系数为 0 1% /hPa ;不同类型的气水分离装置对气氡观测的影响很显著 ;同一含水层的井 (泉 )出水量的短期变化可引起观测水井流量的变化 ,但对气氡测值影响不显著 ;气氡测值对逸出气流量的变化反映不明显 ;逸出气含有杂质及气路泄漏等均会引起测值的下降。结合仪器的工作原理 ,对干扰产生的机制以及排除的方法进行了讨论 |

| Abstract: | In digital measurement of radon gas from subsurface fluid and the use of the obtained data in earthquake prediction, we found that some interference factors have different effects on digital measurement of radon gas. In this paper, the effects of some interference factors, such as atmospheric pressure, atmospheric temperature, discharge of escaped gases, impurity in escaped gases, discharge of well water, leakage of gas pipe and different gas extraction systems on digital measurement of escaped radon gas |
| Keywords: | digital measurement escaped radon data processing interference factors |
