＜正＞A novel topological index ND1、ND2、ND3 based on distance matrix and branch vertex of atoms in a molecule is proposed by defining equilibrium electronegativity of atoms in the molecules and colouring atoms in molecular graph with equilibrium electronegativity, which appears uniquely to the molecular structures and has excellent structural selectivity. A new mathematical model of boiling point for alkane series is introduced from ND1、ND2、ND3 indexes: ln （817.6-Tb）=-0.01644NDl+0.002314ND2-0.00028ND3+6.552538. Using the formula, the boiling points
