摘　　要：诊断比值是油指纹鉴别中非常重要的鉴别指标,本文基于重复性限这一经典的统计学概念,详细介绍了利用重复性限进行溢油鉴别中诊断比值比较的方法,包括方法原理、诊断比值的评价及鉴别原则,并以某原油及其风化样品以及2种不同原油的油指纹鉴别为例,说明了此种方法的有效性,这对于提高基于油指纹的溢油鉴别准确度和效率将有重要意义。The volatile phenolics in seawater were determined by the flow injection analysis-4-AAP method with automated flow injection analyzer developed by Titan Instruments.The detection limit was 0.89 μg/L and liner range was 0.002～0.1 mg/L（r≥0.999）.The relative standard deviation was 1%～5% and recovery for seawater was 90%～110%.The method is rapid,simple and sensitive.The linear range,precision and accuracy all consist with GB standard.
