摘要
利用新增一台同型号SD—3A型自动测氡仪进行新老仪器间对比观测实验,通过改变不同引水管、脱气装置、引水管流量等方式来找出影响气氡观测结果的主要因素。通过半年的对比观测实验,共取得对比观测数据4 433组,根据对比观测实验1至实验5对出水点A的观测结果显示,主测仪器和对比观测仪器对出水点A的观测结果同步,说明主测仪器工作正常,这也与历次标定检查结果一致。而日常监测所测得的低氡值及大幅度动态变化是泉点自身观测采样氡含量变化的正常反映。
We use two instruments （one of them is a new one） to test the measurement stability of the escaped gas random content from ground water with different spring position, input pipes, gas freeing devices and flow amounts. At the same time we try to find the main factors affecting the measurement stability. The testing had been carried out for a half year and 4433 recordings had been obtained. We analyze these data and find that there is no differ- ence between two instruments. The changes of the escaped gas random content from ground water are real.
