摘　　要：为建立一种快速、准确、对被测样品损伤较小的检验皮鞋鞋底的方法,利用傅立叶变换红外光谱仪(FTIR)对收集到的42个不同品牌的皮鞋鞋底样品进行检验,依据红外光谱特征吸收峰的峰数、峰位和峰形对样品进行分类,并利用SPSS24.0软件组间联接法作为类间亲疏程度的度量方法,采用平方欧式距离作为个体间距离的计算方式进行系统聚类分析。结果表明,42个样品可根据材料成分的不同分为五类。该方法灵敏、便捷、具有良好的重现性,可用于鉴别皮鞋鞋底材料。In order to establish a fast, accurate and less destructive method for analyzing leather shoes materials, the Fourier Transform Infrared Spectroscopy (FTIR) was used to determine 42 sole samples of different brands.The samples were classified according to the number, position, morphology of characteristic infrared absorption peaks.The betweengroups linkage method of SPSS 24.0 was used as the class distance, and squared Euclidean distance was used as interval measure for hierarchical clustering.The resulTSshow that 42 samples can be divided into five categories in the light of materials.This method is sensitive, convenient and can be used to identify the materials of shoes sole with good reproducibility.
