【摘要】 分析了用火焰原子吸收光谱法测定铜合金中铅的不确定度的评估,其不确定度来源于样品中铅的含量、样品溶解后的体积及样品质量。通过对各个不确定度的计算,最后计算出合成标准不确定度和扩展不确定度。更多还原

【Abstract】 The uncertainty for the determination of lead in copper alloy by flame-atomic absorption spectrometry was evaluated.The sources of the uncertainty resulted from the determination of lead,the volume of the solution and the weight of the sample were discussed and calculated.The combined standard uncertainty and the expanded uncertainty were reported.更多还原
