摘要
通过对铬铁中铬的不确定度分析,阐述了测量结果不确定度主要来源,并对这些分量进行了量化计算,并合成标准不确定度和扩展不确定度。
Through the analysis on the measurement uncertainty in determining chromium in ferrochromium,this paperelaborates the main resources of measurement uncertainty,and then quantitatively calculates these uncertainty components,andfinally calculates combined standard uncertainty and expanded uncertainty.
