中文摘要:

      针对银量法测定化学试剂氯化钠中氯化钠纯度,讨论了氯化钠纯度测定结果的测量不确定度的来源及评定方法,当K=2,氯化钠纯度测定结果的扩展不确定度为(99.70±0.64)%。

英文摘要:

      In view of the determination of the purity of sodium chloride by the silver method,the sources of the uncertainty and the evaluation methods of the purity determination of sodium chloride were discussed. The expanded uncertainty for the purity determination of sodium chloride was(99.70±0.64)% with K=2.
