| 摘 要： | 采用傅立叶变换红外光谱法对21个5种不同颜色的电线塑料护套样品进行了分析.从红外光谱图中可观察到样品特征峰的峰数、峰位、相对峰面积比均有差异,但可以归纳为两大类.其中同种颜色的不同样品在红外谱图中又反映出了不同的信息,这表明在外观颜色十分相近的情况下,采用此方法能够有效的为刑事案件现场遗留的各种塑料制品提供鉴别与比对.

| Abstract: | 21 plastic wire sleeve samples of 5 different colors were analyzed by FTIR.The characteristic peaks of samples including peak numbers, peak positions, and relative peak area ratios were observed in the spectra, they can be merged into two categories. In the FTIR spectra, different samples of the same color also reflect different information. This suggests that in the cases of plastic sleeves with vary close exterior colors using this method identification and comparison of various plastic products left on the crime scene can be effectively provided. |
