| 摘 要： | SD-3A自动仪器是“九五”期间中国地震局研制的自动测氡仪器，其脱气装置需要根据观测点的具体情况自行设计、制造。为此，笔者通过对武都殿沟泉脱气装置反复试验、改造，研制完成的脱气装置在武都气氡观测中获得良好效果：整点观测值的离散度明显减小，在6个月中（2002年2月至7月）有101个值超过3倍的均方差，降低到（2003年2月至7月）超过3倍的均方差的数值为零，观测值日变化幅度从几千Bq／L，降低到100Bq／L左右。。

| Abstract: | The degassing device of SD-3A automatic instrument of radon measurement should be designed and made according to the condition of the observation point. The degassing device of gas radon measurement in Wudu Station had been tested and changed again and received a better observation result. The whole hour values that exceed three times of mean square deviation were reduced from 101 in three months( from Feb, 2002 to July, 2002) to zero( from Feb, 2003 to July, 2003) in six months. The variation of the values in one day descended from several thousand Bq/L to 100 Bq/L. The stability of the observation values increased obviously. |
