大气压力量值比对结果评价

针对气象计量检定机构组织和实施实验室间比对活动中在编制比对方案、参考值来源、结果评价方法、比对报告等方面的内容进行分析,探讨气象计量实验室能力。通过开展气象计量实验室间的比对工作,确立气象计量检定机构在社会上的专业计量检定地位。比对是验证实验室测量能力的重要手段。主要介绍了2011年由全国压力计量技术委员会气象专业分技术委员会组织,国家气象计量站为主导实验室开展的大气压力量值比对。参加比对的实验室共计8个,比对方式采用了星形比对方式,比对结果的评价采用归一化偏差值方法,比对结果表明所有参比实验室所声明的测量结果不确定度准确可靠。

Evaluation of Atmospheric Pressure Quantity Value Comparison Results

Considering the comparison schemes, resources of reference values, methods of comparison result evaluation, and comparison reports in organizing and conducting comparison activities between laboratories in meteorological metrological verification institutes, the capabilities of the meteorological metrological laboratories are evaluated. The significance of the meteorological metrological verification institutes in professional metrological verification is discussed through comparison between meteorological metrological laboratories. Comparison is an important method used in measurement capability verification for laboratories. The atmospheric pressure quantity value comparison project carried out by the National Center for Meteorological Metrology, as the pilot laboratory, and organized by the meteorological branch technical committee of the National Pressure Metrological Technical Committee in 2011 is introduced. Eight laboratories were participated in the comparison project, and the star-type method is used in the comparison. The normalized deviations of the Eo value method are used for the evaluation of comparison results. The comparison results indicate that all the uncertainties of measurement results claimed by participating laboratories are reliable.
