| 摘 要： | 对滴定法测定精对苯二甲酸酸值的过程中的方法重复性、样品质量、标准滴定溶液、环境温度等方面对不确定度影响进行了评定讨论。结果表明:影响测定结果的主要因素是测定使用的标准滴定溶液的浓度和消耗的体积数。

| Abstract: | The effects of the method repeatability,sample mass,standard titrate solution and enviroment temperature on the uncertainty of PTA acid value determined with titrimetry were assessed and discussed.The results showed that the main factors that have effect on the determination results are the concentration and consumption volumn of the standard titrate solution used for determination. |
