摘　　要：给定一个简单连通图G=(V(G),E(G)),其中V(G),E(G)分别表示图G的顶点集合和边集合。图G的零阶广义Randic指数定义为:R_(a)^(o)(G)=∑_(veV)d(V)d^(a),其中α为非0和1的实数。给出了圈图和路图的r-冠图的零阶广义Randic指数。The zero-order general Randic index of a simple connected graph G is defined as R_(a)^(o)(G)=∑_(veV)d(V)d^(a),where d(v)denotes the degree of v,α is a given real number other than 0 and 1.In this paper,the zero-order general Randic index of the graph I_(r)(C_(n))and I_(r)(P_(n))is given.
