备注

针对SD-3A自动仪器连续数字化自动观测这一技术的基础环节存在的诸多问题,通过对湟源麻尼台的脱气装置进行了反复试验、改造,最终研制完成的脱气装置在麻尼台气氡观测中获得良好效果,改造后数据动态变化明显,整点观测值的离散度明显减小,达到了预期的效果。

Because of there still exists many problems in basic factor of gas water separating in the technology of the continuous digital automatic observation by SD-3A automatic instrument,the degassing device of gas radon measurement at Huangyuan Mani Station had been tested and refitted repeatedly. After the refitment,the degassing device received a good result in observation at Huangyuan Mani Station,such as the dynamic variation of data was obvious,and the dispersion of hour observation value decreased obviously,which achieved the expected result.
