三角链是由若干个正三角形且任意相邻两个正三角形只有一个公共顶点构成的1-连通图.主要研究n个正三角形构成的三角链的Merrifield—Simmons指标和Hosoya指标,并给出其计算公式.
Triangular chains is a 1-connected graph that consists of several regular triangle and any two adjacent regular trian- gles with only one common vertex. This paper mainly discusses Merrifield-Simmons index and Hosoya index of Triangular chains consisting of n regular triangles and its formula of computation.
