摘　　要：采用色谱/质谱联用法(GC/MS)与偏最小二乘回归结合的方法测定了原油的API比重指数,汽油馏分、柴油馏分的密度,建立了采用MS数据预测上述性质的PLS校正模型。验证集结果表明,GC/MS方法与标准方法测定的结果之间无显著差别。A new method was developed for rapid crude assay by GC/MC with standard methods as reference. PLS rectifying models, including API gravity of crude and relative densities of gasoline and diesel fractions, were established by using partial least square regression. The result of validation showed that there was no evident difference between the said method and standard methods.
