摘要
根据分子图的信息计算出柴油中各种烃类分子的ＮＣ指数、Ｊ指数、Ｐ３指数和ｆ指数，并将这些反映分子结构信息的指数与柴油中烃类的十六烷值进行多项式拟合。在所得拟合式中，链烷烃拟合式的相关系数Ｒ２为０．９５８，剩余标准差Ｓ为６．１３６；环状烃拟合式的相关系数Ｒ２为０．９９１，剩余标准差Ｓ为２．
According to information of the molecular graphics, the indexes of N\-\%C\%,J,P\-3
\%and \%f\% for various hydrocarbon molecules in diesel oil were calculated. These indexes
and the cetane number of hydrocarbons in diesel oil were regressed. The correlation coefficient
of regression \%R\+2\% and the standard error \%S\% are 0.958 and 6.136 respectively for the
paraffins in diesel oil, and the \%R\+2\% and \%S\% are 0.991and 2.053 respectively for the
cycle hydrocarbons in diesel oil. \=
