摘要
文章介绍了测量不确定度区间表达方式使用中注意的事项;阐述了不确定度预评定过程时应注意的问题,并以电测仪表为例,介绍如何运用线性回归计算给出区间不确定度的表达方式;结合实际工作经验,给出不确定度使用过程中需要注意的几个问题。
This paper introduces some problems that should be paid attention to in the expression of measurement uncertainty;expounds the problems that should be paid attention to in the process of uncertainty pre-evaluation,and taking the electric measuring instrument as an example,introduces the evaluation of uncertainty by linear re-gression calculation.Based on experience,give some points to be noted in the use of measurement uncert ainty.
