摘　　要：介绍了ICP-AES法测定八氧化三铀中镍质量分数的测量结果不确定度的影响因素,对各不确定度分量进行了分析和计算。八氧化三铀中镍质量分数为4.0μg/g时,测量结果的扩展不确定度为0.3μg/g。The influencing factors on uncertainty of measurement result for nickle in U3O8 by inductively coupled plasma atomic emission spectrometry are introduced. The components of the uncertainty of measurement result are analyzed and calculated. The expanded uncertainty of measurement result for nickle is 0.3 μg/g when mass fraction of nickle in the U3O8 is 4.0 μg/g.
