摘　要:為解決電子天平在測量過程中達到用測量不確定度來統一評價測量結果質量的問題,對電子天平測量結果不確定度進行了研究。依照電子天平復現質量之差的原理,采用分析誤差源的方法,研究測量過程中用電子天平來復現質量,給測量結果引入不確定的范圍。通過本方法的研究而得到電子天平測量結果不確定度,對電子天平測量結果的質量有了比較可靠的保證。[著者文摘]

Research on measurement remit uncertainty of electronic balanceXIAO Tong, YANG Hui-min, LIU Qiang Tianjin Institute of Metrological Supervision and Testing,Tianjin 300192,ChinaAbstract:The problem of evaluating the quality of measurement result was solved by research on uncertainty of measurement of electronic balance. In accordance with the principle of reproducibility of quality errors of electronic balance, the source of errors was analyzed, reproduce quality in the course of measurement which introduced the result into an uncertain field was researched. The uncertainty gained through the research of this method ensures the quality of the result of a measurement of electronic balance.[著者文摘]

Key words:Measurement; Uncertainty of result of a measurement; Confidence factor, Confidence level; Expanded uncertainty
