摘要
论述了氦中氪、四氟化碳气体标准物质的制备方法、稳定性参考值、不确定度计算,证明达到国家二级气体标准物质要求。研制方法可行,量值准确可靠。
The preparation method of gas reference material for Kr and CF4 in He is discussed. It is proved that the gas reference material reaches the standard rate of secondary reference material from its reference value of stability and calculation of uncertainty. This preparation method is feasible and the value is exact and reliable.
