摘要
对锰矿中全铁含量进行了分光光度法检测,分析了不确定度来源进行测定,建立了不确定度数学模型。对数学模型中各个参数的不确定度成分进行评估和综合,从中识别出影响该方法不确定度的关键因素。标准不确定度为0.016%的测算检测结果,扩展不确定率为0.032%。
Using spectrophotometry,the total iron content of manganese ore was calculated.Analysis was done on the causes of the process of determining uncertainty,and the uncertainty mathematical model was developed.The uncertainty components and synthesis of each parameter in the mathematical model are evaluated,and the main factors affecting the uncertainty of the method are obtained.0.016%was the test result standard uncertainty;0.032%was the expanded uncertainty.
