摘要
给出了毛毛虫,星,香蕉树和鞭炮的定义,进而利用一定的计算技巧求出了香蕉树和鞭炮的距离和及平均距离.图的距离和及平均距离是图的非常重要的参数,在结构化学,建筑学,通讯网络等领域都有重要应用.
The definitions of caterpillar, star, banana tree and firecracker are given firstly, and then the sum of all distances and average distance on between banana trees and firecrackers were calculated by using some calculation skills. The sum of all distances and average distance are very important parameters of graph, and they are widely applied in structural chemistry, architecture, communication network, etc.
