摘要
本文针对SD-3A气氡仪观测九江地震台2号井近年气氧观测值不稳定、连续性和可靠性较差等问题进行设计实验。采用控制变量实验方法，新测氧仪器BL2015测氧仪和电动鼓泡脱气-集气装置参与实验。SD-3A测氡仪、BL2015测氧仪分别在溅散式脱气-集气装置和电动鼓泡脱气-集气装置下实验，得到溅散式脱气-集气装置是观测氧值不稳的主要原因，而电动鼓泡脱气-集气装置氧观测值比较稳定、且连续性和可靠性均比较好。
Aiming at the observed values of gas radon, which were observed by SD-3A gas radon observation instrument in Jiujiang Seismic Station No. 2 in recent years, are unstable, discontinuous and unreliable, the experiments were designed. Experiments apply the observing system designed by electric bubbling degassing-gas collection device and BL2015 radon measuring instrument to observe the changes of radon measuring value through the control of a single variable. SD-3A and BL2015 radon detector test on sputtering degasifying - set gas device and electric bubbling degassing- gas collection device respectively, the main reason for the observed values of instability is the sputtering degasifying - set gas device, while electric bubbling degassing-gas collection device is stable, continuous and reliable.
