摘　　要：现代固体激光器、光谱仪技术和软件技术的进步使激光拉曼光谱快速进入实用阶段,并开始广泛地用于物质结构分析与鉴定。文章详细地阐述了拉曼光谱的基本原理,指出拉曼光谱的本质是可见/近红外光谱,重点对采用激光拉曼光谱进行物质鉴别分析时常用的三类相似性测度方法——距离测度、相似性函数和峰匹配作了深入的分析,并就各种方法的特点做了说明。The progress of the solid laser,spectrometer and the software technology makes the laser raman spectroscopy into actual applications and the portable laser raman spectrometer has been used for the structural analysis and discrimination of substances widely.Here the basic principle of the laser raman spectroscopy was expounded and the laser Raman spectrum is visible / near infrared spectrum substantially.It has been deeply analyzed that three kinds of measures of the similarity of the laser Raman spectra and the applicability of the different evaluation methods were reviewed
