常用玻璃量器测量不确定度分析报告

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.
