摘要:
针对目前中国地震领域气氡观测的稳定性和水气比等问题,设计新型气氡观测系统并进行实验研究.基于流体力学原理设计恒流装置控制采样水流量,脱气集气装置内鼓泡脱出氡气并传输,利用AlphaPUPM主动泵控制鼓泡气流量,AlphaGUARD PQ2000测氡仪测量气体的氡放射性活度浓度,组合成一套新型气氡观测系统.采用控制变量法开展实验,实验结果表明,在一定范围内,氡观测值随采样水流量增大而增大,但与鼓泡气流量呈负相关;氡观测值与水气比呈线性正相关,且两者具有一定的变化限值区间,该变化限值区间为地震氡观测异常核查量化研究提供了参考依据.
Abstract:
In view of the stability of gas radon observation and the water-gas ratio in the field of earthquake, a new radon observation system is designed and experimentally studied. Based on the principle of hydromechanics, a constant-current device is designed to control the sampling flow. Radon gas bubbles produced within the gas degassing-gathering device are transmitted. The AlphaPUPM is used to control bubble gas flow, and the radon radioactive activity is tested by AlphaGUARD PQ2000 emanometer. The above equipmental devices constitute a whole new type of gas radon observation system. The control variable method is used to carry out the experiment. The experimental results show that, within a certain range, the measured radon value is negatively correlated with the bubbling gas flow, and increases with the increase of the sampling water flow. The radon observation value is linearly positively correlated with the water-gas ratio, and there is a certain variation limit range between them, which provides a reference for the verification and quantification of seismic radon observation anomalies.
