摘　　要：目的:对灯罩残片进行快速、准确地鉴定,能够更快地对肇事逃逸车辆进行筛选,进而锁定侦查方向,提供破案依据。方法:利用傅立叶红外光谱法对27个不同品牌、同品牌不同型号的汽车灯罩残片进行分析,依据红外光谱图中特征峰的峰位等进行种类的鉴别及样品均匀性的考察。结论:傅里叶红外光谱法,能够快速分析遗留在现场的车灯残片的主体成分,为快速侦破案件提供有力的依据。Objective： To quickly and accurately identify the shade debris, to be able to more quickly escape the vehicle to escape, and then lock the direction of detection, to provide detection basis. Methods： Two different brands and different brands of car shade were analyzed by Fourier transform infrared spectroscopy （FTIR）. The identification of the species and the homogeneity of the samples were carried out according to the peak position of the characteristic peaks in the infrared spectrum. Conclusion： Fourier transform infrared spectroscopy （FTIR） can quickly analyze the main components of the residual lights in the field, and provide a strong basis for the rapid detection of cases.
