| 摘 要： | 粘度法测定了聚乙二醇的相对分子质量,并对测定结果的不确定度进行了分析和评定。通过对测定过程中的各种不确定度分析,得到了测定结果的不确定度主要由溶液配置过程中的容量瓶体积和移液管体积引入的不确定度组成,其他方面的组成较小,在实际评定中可以忽略。

| Abstract: | The relative molecular weight of polyethylene glycol was determined by viscosimetry. The uncertainty in measurement was evaluated and discussed.After analyzing all kinds of uncertainty in determination, it was found that the uncertainty of results was mainly introduced by those of repeatability, but other uncertainty was very trivial and can be neglected in real evalution. |
