中文摘要：

为实现对有机物混合物的快速、无损检测，提出一种基于激光拉曼光谱技术的二维分析方法。研究结果表明，采用532 nm波长激光作为激发光源，观测到236.2，348.9，449.4，513.6 cm -1四条振动拉曼谱线，且这些谱线的强度比为6.4∶1.7∶9.4∶1.0，可确定四氯乙烯的存在。观测到707.5，1087.9，1175.8，3078.6 cm -1四条振动拉曼谱线，其强度比为9.6∶6.4∶1.0∶3.9，可确定氯苯的存在。即通过综合分析特征谱线及若干特征谱线的强度比，可快速判断有机混合溶液中某种物质的存在。在定量分析方面，采用多光谱分析结合最小二乘法拟合提高了测量的可靠性，所测样品浓度的准确率为98.4％。本研究为有机物混合物成分识别和浓度探测提供了一套可行的光谱测量方法，有着十分重要的应用前景。

The observation of 707.5 ,1 087.9 ,1 175.8 and 3 078.6 cm -1 ,the four vibrational Raman spectra ,and the intensity ratio of 9.6∶6.4∶1.0∶3.9 can determine the existence of chloro-benzene. In other words ,that through the comprehensive study of spectral lines and intensity ratio of some spectral lines ,the presence of organic compounds in the mixed solution can be determined quickly. In the aspect of quantitative analysis ,using multi-spectral analysis combined with least square fitting method can improve the reliability of the measurement ,The accuracy of sample concentration was 98.4%. This spectral measurement method is a potential tool for organic component identification and concentration analysis which has a prosperous application prospects.
