纤维是刑事案件现场上常能获得的微量物证之一，微量纤维上染料组成和配比的鉴别可为侦破案件提供有力的证据．纤维上染料定量分析方法据报道有正交函数分光光度法［１］、液相色谱法［２］、系数倍率导数法［３］等。本文用ｔ检验的方法对液相色谱法的测定结果进行分析，结果
Fibers are one of the trace evidences that can often be obtained on the scene of criminal cases. The identification of the composition and proportion of dyes on the microfibers can provide strong evidence for detecting the cases. Quantitative analysis of dyes on the fiber has been reported with orthogonal function spectrophotometry [1], liquid chromatography [2], coefficient multiplication derivative method [3] and so on. In this paper, t test method for the determination of liquid chromatography results, the results
