摘　　要：按照《测量不确定度评定与表示》和《化学分析中不确定度的评估指南》要求,对实验室过滤法测定航空燃料颗粒污染物含量的过程进行分析,结合实例对测量不确定度进行评定。结果表明影响测量结果准确性的主要因素是重复性测定。颗粒污染物结果为0.30 mg/L时扩展不确定度为0.04 mg/L(k=2)。Based on ＆quot;Evaluation and Expression of Uncertainty in Measurement＆quot; and ＆quot;Guidance on Evaluating the Uncertainty in Chemical Analysis＆quot;,actual determination process of particle pollutant in aviation fuel by laboratory filtration method was analyzed. Combined with examples, the uncertainty in the determination was evaluated. The results show that, main influence factor of the uncertainty is the repeatability. When the particle pollutant is 0.30 mg/L, the expanded uncertainty is 0.04 mg/L （k=2）.
