摘要
介绍了氮中微量氧标准气体在研究过程中稀释气体高纯氮中氧分析不确定度的评价依据,给出了评价过程和结果。讨论了氧气体标准物质在有效期内变化不确定度的计算方法,对氧气体标准物质定值不确定度进行了评价。
The high purity nitrogen was inert diluents gas during preparing the micro-oxygen in nitrogen calibration gases, as a result the content of oxygen in nitrogen was important technical target. We have done large numbers of experiments in order to.obtain exact data. In this paper the basis, process and result were introduced of evaluating the analysis uncertainty. We have discussed the design procedure of the change uncertainty of the micro-oxygen in Nitrogen calibration gases which was remain in force, in addition We have evaluated definiting value uncertainty of the calibration gases.
