梯形图线图的一些基于度的拓扑指数

Some Degree-based Topological Indices for the Line Graph of Ladder Graph

图论在电子和电气工程领域中,尤其在信号处理、网络、通信理论等方面起着重要作用.拓扑指数(TI)是附有图网络的实数,并将化学网络与物理网络联系起来,表示化学性质和化学反应性,其共有148种以上的拓扑指数,可是其中没有一个能够完整描述该分子化合物,但它们在某种程度上可以做到这一点.因此,总是有空间定义新的拓扑索引.

Graph theory has an important role in the field of electronic and electrical engineering,such as in signal processing,networking,communication theory,etc.A topological index(TI)is a real number attached with graph networks and correlates the chemical networks with physical and chemical properties and chemical reactivity.There are more than 148 topological indices but none of them completely describe the molecular compound,but together they do it to some extents.Therefore,there is always space to define new topological indices.
