摘要
通过碘量法测定鹿鸣矿业铜精矿中铜含量,根据测量不确定度的评定方法,对其测量不确定度进行评定,分析了实验过程中不确定度的来源,并对不确定度分量进行分析计算,求得标准不确定度为0.04,扩展不确定度为0.08。
The copper content in Luming copper concentrate was determined by iodometry.According to the evaluation method of measurement uncertainty,the uncertainty of measurement was evaluated,the source of uncertainty in the experiment was analyzed,and the uncertainty components were analyzed and calculated.The standard uncertainty was 0.04 and the expanded uncertainty was 0.08.
