摘　　要：借助拓扑指数,有利于对有关图形族的拓扑数值量的理解,也可以更好地了解相关的图族.为探讨确定带路径的循环根生成细分的线图基于度的拓扑指数,利用边分解和图结构分析方法,计算了带下划线的图族的调和指数、Randic类型指数、对称除法指数、原子键连通指数、调和指数、对称分割指数、几何算术指数、广义逆Randic指数和逆和指数等.With the help of topological index,it's helpful to understand the numerical quantities of concerned family of graphs.The aim of the present report is to determine the degree-based topological indices of the line graph of the subdivision of rooted product of cycles with paths.By means of edge dividing and graph structure analysis,we computed Harmonic index,Randic type indices,symmetric division index,atomic-bond-connectivity index,harmonic-index,symmetric division index,geometric-arithematic index,generalized reverse-Randic index,and inverse sum index of underlined family of graphs.
