摘要
文章对化验室中常见的分度吸管测量的不确定度进行了评估,分析了测量过程中存在的不确定度来源,并建立了测量过程的数学模型,量化不确定度分量,求出合成不确定度和扩展不确定度。
In this paper,the common measurement uncertainty indexing straw were evaluated in laboratory analyzes the measurement uncertainty sources exist,and a mathematical model of the measurement process,quantify uncertainty components, obtained combined uncertainty and expanded uncertainty.
