摘　　要：该文简介了GUM法评定测量不确定度的常见应用场景及主要不足,提出了应用GUM法时的高效评定方案:理顺流程,测量模型为先;统一符号,按输入量分层次分析来源,评定分量;合理转换,弱化自由度,简化合成不确定度和扩展不确定度评定;采用EXCEL突破计算繁琐难点。并提供了一个应用实例。This paper introduces common application scene and main short when evaluate uncertainty of measurement by GUM way,advance high efficiency evaluate uncertainty of measurement by GUM way:smooth procedure,give priority to the model of measurement;uniform symbol,analyse source according to input leves;rational change,avianize degree of freedom,simplify evaluate combined standard uncertainty and expanded uncertainty;break the difficult of calculations by EXCEL.in addition this paper produced a living example.
