摘　　要：本文通过分析影响不确定度的因素,结合分析样品制备过程、定容体积、曲线拟合、等因素对不确定度分量的影响,对不确定度进行了评估,同时结合检测结果对不确定度的评判标准进行说明,从而确定各种元素之间的关系。发现不确定度的来源主要为元素校准曲线拟合及重复性。In this paper,we have an assessment of uncertainty according to the analysis of influence factor of uncertainty,in combination with the analysis of influence of sample preparation,constant volume volume,curve simulation,etc factor on uncertainty,and interpretation of the assessment standard of uncertainty in combination to the testing result,dertermination of relationship between various elements.We find out the uncertainty is resulted mainly from the simulation and repeat of element correction curve.
