摘　　要：综合理论分析与实践调查,对火焰原子吸收法测定水中锰的不确定度展开分析。在简要概述测定实验中所需的材料与方法后,为其实际测定中不确定度评定建立数学模型,对其不确定度的分量来源加以归纳,并对各分量造成的不确定度加以计算。最后通过各分量的合成与拓展,得出水中锰测定中不确定度的具体数值。Based on comprehensive theoretical analysis and practical investigation,the uncertainty of flame atomic absorption method for determining manganese in water was analyzed.After a brief overview of the materials and methods required in the measurement experiment,a mathematical model was established for evaluating the uncertainty in actual determination.The sources of uncertainty are summarized,and the uncertainties caused by each component are calculated.Finally,through synthesis and extension of each component,the specific value of uncertainty in the determination of manganese in water was obtained.
