摘要
Merrifield-Simmons指标是化学分子图论研究中较为流行和重要的拓扑指标之一.为了方便,快速地计算出聚苯链的Merrifield-Simmons指标,采用递推法得到了3种特殊聚苯链Zn,Sn和Ln的Merrifield-Simmons指标的计算公式,经过一些矩阵运算后,得到了这3种聚苯链的Merri-field-Simmons指标的更为一般的计算公式.
The Merrifield-Simmons index is one of the popular and valuable topological indices in chemistry molecular graph theory.In order to calculate the Merrifield-Simmons index of polyphenyl chains fast and convenient,the formulae of the Merrifield-Simmons indices of three special polyphenyl chains Zn,Sn and Ln were obtained by using recurrence method.After some matrix operation,the more general formuale on the Merrifield-Simmons index of the three polyphenyl chains are given.
