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。
Diagnostic ratio is a very important discriminating index in oil fingerprint identification. Based on the classic statistical concept of repeatability limit, this paper introduces in detail the method of comparing the ratio of diagnostic odds in oil spill identification based on repeatability limit, including principle of method, diagnostic ratio The evaluation and identification principle of a crude oil, its weathering sample and the identification of two fingerprints of different crude oils illustrate the effectiveness of this method. This will help improve the accuracy and efficiency of oil fingerprinting based identification of oil spills There’s important meaning.
