根据相对标准不确定度的定义,对JJF 1059.1—2012中公式(29)、(30)的表达形式进行分析;同时给出了当各输入量间相关时,合成标准不确定度的计算公式,并就有关实例进行了分析。
According to the definition of relative standard uncertainty, the expressions of formulas (29) and (30) in JJF 1059.1-2012 are analyzed. At the same time, formulas for calculating the standard uncertainty when the correlation between input variables are given are given. And the relevant examples were analyzed.
