文摘1.INTRODUCTIONMolecular topological property is an important property.A molecular topo-logical index is an invariant of molecular graph.Since the fist topologicalindex was put forward in 1947 by Wiener,just over 40 different topolo-gical indices have been documented in the literature to date.The theoryof molecular topological indices has become a more effective and simplermethod of studying the relationship between molecular structure and its phys-ical properties,chemical properties and biological activity.
