目的 为快速无损地检验犯罪案件现场遗留的药品铝塑包装片。方法 采用最新的差分拉曼光谱仪，并基于化学计量学对收集的51个药品铝塑片样本进行分析。结果 共对收集的药品铝塑包装片样本提取出了9个有效光谱成分因子，累积占原始光谱数据99.54%的有效信息，并将51个样本分为4大类，通过相关性比较，可知分类结果较好。结论 实验方法简便，无损检材重现性实验结果较好，为药品铝塑包装片类物证的检验提供依据，可为公安工作的开展提供有效帮助。

The work aims to quickly and accurately carry out non-destructive test to the drug aluminum plastic packaging tablet left at the crime scene. The latest differential Raman spectrometer was used to analyze the 51 samples of drug aluminum plastic packaging tablets collected at the crime scene based on chemometrics. A total of 9 effective components were extracted from the collected samples of drug aluminum plastic packaging tablets, with accumulated effective information accounting for 99.54% of the original spectral data. Then, the 51 samples were divided into 4 categories. Through correlation comparison, the classification results were better. The experimental method is simple and reproducible, and the experimental results of non-destructive test are good, which provides the basis for the inspection of material evidence of drug aluminum plastic packaging tablets and can effectively help the development of public security work.
