摘要
为建立案件现场常见橡胶鞋底物证的分类方法,利用X射线荧光光谱,对40个不同品牌、不同系列的橡胶鞋底样品中的无机元素进行了检验。并结合多元统计学,分别选用主成分分析法、k均值聚类法及判别分析法等对实验结果进行分析。结果表明,该方法简便快速、结果准确可靠且无损检材,对样品的分类效果较好。利用该方法可以对橡胶鞋底物证进行分类。
The study aims to establish a convenient,sensitive and accurate way to analyze debris examples of rubber soles collected from various crime scenes.40 debris examples of rubber soles from different brands,different series and variety use were analyzed by energy dispersive X-ray fluorescence spectrometry for mineral element.Samples were classified by using multivariate statistical methods including principle component analysis,k-means method and discriminant analysis.Conclusion indicates that this method is lossless and has good reproducibility.This method can be used to classify the material evidence of rubber soles.
