摘要
本文用母函数方法求出有一环及一直链的环烷烃的异构体的个数公式,并用二部分拆实现之,由此再讨论了分子式C_nH_(2n)的异构体的个数的一些问题。
In this paper we find out the compute formula of the number of isomer of such a kind of cyclanes having one link and a straight branch by means of the generating function. Let a denote the number of carbon atom, then the above number is given by n- 3 ( n>4 ) . And, these covalent molecules are realized with the aid of the unordered partition in two parts. In addi -tion, we also discuss some problems of the valence boud structure of formula
