容量法测定锰矿石中锰不确定度评定

以硝酸铵-硫酸亚铁铵容量法测定锰矿中锰为例进行系统的不确定度评定。不确定度的来源主要包括分析过程中所用的仪器设备、标准工作溶液、试液定容体积及测量重复性等引入的不确定度分量。计算出各分量的不确定度，通过合成得到测量结果的标准不确定度、扩展不确定度及测试结果的报告形式。

Determination of Manganese Ore Capacity of Manganese Uncertainty Evaluation

To ammonium nitrate-ferrous sulfate ammonium Determination of manganese ore capacity of manganese as an example of the uncertainty evaluation system.Analysis of the uncertainty of the important sources,including analysis of the process used in the equipment,standard solution,test solution for measuring the size and capacity,such as the introduction of repeatability of uncertainty in component form.Calculation of the amount of uncertainty,through measurement of results by the standard uncertainty,uncertainty...
