中文摘要:
      目的 研究浸渍法测量高密度聚乙烯瓶密度的不确定度来源。方法 采用浸渍法对同批口服固体药用高密度聚乙烯瓶的密度重复进行了多次测量,分析了测量不确定度来源,并画出了来源因果图;建立了测量模型,对影响测量结果的各个不确定度分量分别进行了评定,并计算了合成标准不确定度和扩展不确定度。结果 被测量的同批次口服固体药用高密度聚乙烯瓶密度为0.950 g/cm3±0.002 g/cm3,其分散性在±0.002 g/cm3之间,符合规定。结论 测量过程中对测得值影响较大的非重复性因素为浸渍液温度。
英文摘要:
      The densities of HDPE bottles with the same batch were determined by impregnation method. The measurement uncertainty sources were identified and analyzed and the cause-effect diagram was described. According to the measurement model, each of the contributors to the uncertainty was evaluated, and the combined standard uncertainty of the density measurement was calculated as well as the expanded uncertainty. The results indicated that the density of the HDPE bolltles was measured to be 0.950 g/cm3 ± 0.002 g/cm3, with a dispersion between ± 0.002 g/cm3, which conformed the national standard. The main contributor to the type B uncertainty of the density measurment was the auxiliary liquid temperature.
