引入了一个新的参数--入口数（r），它与苯型体系和亚苯基体系的结构有关，而且很容易由它们的结构确定。的连接性（Randi）指数的苯系统和苯，然后示出仅依赖于顶点的数量和r。一个简单的关系之间建立连接指数的亚苯基和相应的六方挤压。类似的关系报告的边缘连接指数。
A new parameter, related to and easily determined from the structure of a benzenoid system and that of a phenylene – the number of inlets (r) – is introduced. The connectivity (Randi}) index of both benzenoid systems and phenylenes is then shown to depend solely on the number of vertices and on r. A simple relation is established between the connectivity index of a phenylene and of the corresponding hexagonal squeeze. Analogous relations are reported for the edge-connectivity indices.
