摘要
讨论了用GB/T7531标准方法测定精对苯二甲酸中灰分的测量结果不确定度的各种影响因素。通过对影响结果不确定度分量的分析和量化,以及分量之间相关性的计算,求出精对苯二甲酸中灰分测量结果的标准不确定度和扩展不确定度,对测定结果进行了表述。
Various factors affecting uncertainty for the measurement of ash content in purified terephthalic acid by the standard method GB/T7531 were discussed.Though analysis,quantizing and calculating these factors,uncertainty for the measurement of ash content in purified terephthalic acid was evaluated,and the measurement was described.
