圈链是一类由若干个n阶圈构成的平面连通图.构造了两类特殊的圈链,并且研究了这两类圈链在不同构联接位下的Merrifield-Simmons指标和Hosoya指标,给出了相应的递推公式.
Cycle chains is a kind of plane connected graph that consists of several n order cycles.Two kinds of special cycle chains are constructed,and the Merrifield-Simmons index and Hosoya index are studied under non-isomorphic connected positions.The recurrence formulas of the two indices are given.
