摘要
The total number of the RNA secondary structures with a limited length m in each hairpin loop, that is, S(m)(n) has already been studied. In this paper, the number of this kind of RNA secondary structures is discussed with the technique of combinatorics. As a result, the recurrence relations, generating functions, explicit expressions, and some other properties were obtained. Furthermore, a new method to compute S(m)(n) is given in the end.
