| 摘 要： | 用已建立的渣油聚类和识别模型将渣油分为坟渣油、减压渣油和加氢渣油，用紫外－可见光谱－偏最小二乘法（ＵＶ－ＰＬＳ）分别建立了这３种渣油的饱和烃、芳烃、胶质和沥青质四组分测定模型。该方法的测定结果与经典洗脱色谱法（ＥＣ）的结果相吻合。与ＥＣ方法相比，该方法具有快速、操作简单、不需分离，重复性好等特点。

| Abstract: | The calibration models of saturates, aromatics, resins, and asphaltenes, four comopent contents, in three types of residues have been established by partial least squares (PLS)- ultravioletvisible spectraophotometry (UV). The results predicted by this method were very close to those determined by elution-adsorption chromatography(EC). Compared with EC, this method is provided with advantages such as high-speed, simplicity, no-separation, and good repeatability. |
