采集31种爆炸物和73种毒品的标准拉曼谱图，分析其谱图，选出适合作为搜索条件的光谱范围。通过编程，建立标准拉曼谱图库和自动检索系统。在选定光谱范围内，拉曼谱图库选择信号较强的特征峰，进行曲线拟合，将获得的峰位置、相对峰强等数据作为参数写入标准拉曼谱图库。通过自动检索系统将未知拉曼光谱与数据库中的标准谱图进行分析比对，搜索软件自动给出正确结论。数据库具有添加、删除、备份、恢复等辅助功能，并具有自动扣除荧光背底，优化拉曼光谱图等功能。本文进一步分析了可能对分析比对结果造成影响的因素。

31 kinds of explosives and 73 kinds of drugs were recorded the Raman Spectrum, the correct region of Raman spectrum was selected to be the normal to used in database. Database of normal Raman spectrum and information search system is build by software. In correct information of Raman frequency shift and height is recorded in the database. The Raman spectrum of unknown was compared with region of Raman spectrum, Raman peaks that are strong, are curve fitted, then the with the normal Raman spectrum in the database by information search system, the result is correct. The database has the function of add, delete, back up, recover and subtract baseline. Some facts will influence the search result is analyzed.
