摘要 给出了图的一种新ABC指数定义为ABC(G)=∑uv∈E(G)((Du+Dv-2/DuDv)~(1/2)),其中Du是图G中各顶点到顶点u的距离之和.证明了该指数与辛烷同分异构体的ABC指数、Acentric因子、熵之间存在好的线性相关性,确定了该指数的一些基本性质,刻画了具有这种指数最小值的树. A novel atom-bond connectivity index for a(molecular) graph is defined as ABC(G)=∑uv∈E(G)((Du+Dv-2/DuDv)~(1/2)),where Du is the distance sum of vertex u in G.It is shown that there exists a good linear correlation between this atom-bond connectivity index ABC and Acentric factor,entropy of the octane isomers.Some basic properties for this index and the tree with the minimum value of this index are determined.
