氙气质量流量计校准装置测量不确定度评定

摘要

通过建立氙气质量流量计校准的测量模型，分析了测量不确定度分量，最后合成了氙气质量流量计校准装置的相对合成标准不确定度，并对评定结果进行了分析讨论。%In this paper the measurement model of gas mass flow meter with xenon was set up, measurement uncertainty was analysed, the relative combined standard uncertainty of calibration appara-tus was given, then the evaluation results were discussed.
