树状聚合物可用于药物的重要结构研究,掌握其性质具有重要意义.由于有时会受到实验条件的限制,有许多研究树枝状聚合物性质的实验几乎不可能在实验室完成.而拓扑指数在这方面能够提供帮助,即研究人员无须进行实验则可预测树状聚合物的性质.因此,运用拓扑指数对最重要的树状聚合物结构之一,即(丙基)醚亚胺PETIM树状聚合物的性质进行研究,同时计算了该聚合物的几个逆指数以及第1和第2逆萨格勒布多项式.“,”Dendrimers that are useful in medications are important structures research.To understand the properties of dendrimers is an important task.it is almost impossible to study properties of dendrimers in lab due to the limits of experimental conditions.But Topological indices provide help so researchers can predict properties of dendrimers without performing experiments.In this paper,we study one of the most important dendrimer structure namely(propyl)Ether Imine PETIM dendrimer and compute several reverse indices and first and second reverse Zagreb polynomials for(propyl)Ether Imine PETIM dendrimer.
