| Abstract: | 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. \= |
