摘　　要：用高分辨气相色谱详细分析了汽油组成，按各组分的辛烷值特性分组，并与标准方法所测定的辛烷值进行关联，得出了每组的质量有效辛烷值及准确计算的ＭＯＮ和ＲＯＮ．本方法将国内外普遍采用的３１组分组改缩至２１组，分析时间只需３５ｍｉｎ．Gasoline compositions were separated by high resolution gas chromatography (HRGC) and were divided into 21 groups.Octane numbers measured with standard CFR method were correlated with the compositions by HRGC according to groups. The coefficient or mass effective octane number of each group in a linear equation was calculated by regression.With these coefficients,MON or RON of any gasoline samples can be calculated from the established equation.Time consuming is approximately 35 minutes per sample,much shorter than the former method.
