摘      要：The Hosoya index of a graph is the total number of matchings in *** the Merrifield-Simmons index is the total number of independent sets in *** are typical examples of graph invariants used in mathematical chemistry for quantifying relevant details of molecular *** this paper,we obtain explicit analytical expressions for the expectations of the Hosoya index and the Merrifield-Simmons index of a random polyphenyl chain.
