| 摘 要： | 研究了原油的三维荧光猝灭现象，指出浓度过高是原油产生荧光猝灭的主要原因，将会造成三维荧光等值线图畸变，致使定量分析数据失真，谱图特征变异，难以获取原油特征三维指纹图。提出了避免荧光猝灭的预试方法，并列出了不同类型原油的最佳测试浓度。

| Abstract: | The quench phenomena in three dimension fluorescence determination of crude oils were studied and the high concentration of sample is the primary factor of fluorescence quench,which will cause the distortion of contour plots and result in false analytical data and error characters of spectra.In this case,it is impossible to obtain the three dimension fluorescence fingerprint spectra of crude oils.We also describe a pretest mothod to avoid fluorescence quench and give the optimum concentration ranges for determination of various orude oils. |
