中文摘要：

激光拉曼光谱技术是基于拉曼散射理论的检测技术，具有快速、无损、样品无需预处理等优点。运用激光拉曼光谱技术对苯的25种不同浓度的样品进行了研究，结果表明，在184．8g／L-0．264g／L浓度范围内，苯的振动拉曼光谱强度与其浓度呈线性关系，利用最小二乘法拟合得到线性相关系数R=0．99626，检出限为0．223g／L。

英文摘要：

Laser Raman spectroscopy technique based on Raman scattering theory has the advantages of rapid, nonde- structive, and without sample pretreatment. 25 samples of benzene with different concentrations are studied by using la- ser Raman spectroscopy technique. The results show that in the 184. 8g/L-0. 264g/L concentration range, the linear re- lationship between the intensity of Raman lines of benzene and its concentration. The linear correlation coefficient of R= 0. 99626 is obtained by using the least square method. The detection limit is 0. 223g/L.
