化合物和药物一般用图模型来表示,其中顶点表示分子中的原子,边表示连接原子之间的化学键。此类化学结构导出的图称为分子图,而定义在分子图上的指标与该化合物的化学性质密切相关。顶点带权维纳数作为拓扑指数,用来衡量特定有机分子结构的特性。借助于分子结构分析,并根据p,q不同的取值进行讨论,给出纳米管TUC4[p,q]的顶点带权维纳数。
Compounds and drugs are generally represented graphically, where the vertices represent the atoms in the molecule and the edges represent the chemical bonds between the atoms attached. The graph derived from such a chemical structure is called a molecular graph, and the indicators defined on the molecular graph are closely related to the chemical properties of the compound. Vertex weighted Wiener number as a topological index, used to measure the characteristics of a particular organic molecular structure. With the aid of the molecular structure analysis and the discussion based on different values of p and q, the vertex weighted Wiener number of nanotube TUC4 [p, q] is given.
