Keywords:
A tree is called to be a blossomed double star if the graph obtained from the tree by deleting its all pendent vertices is a double star.In this paper; the problem on the extremal Wiener indices of blossomed double stars was considered; and the minimal Wiener index of the blossomed double star with a fixed number of vertices was completely characterized.

摘要:
一个连通的无圈分子图（树）称为双繁星，如果删去其所有悬挂点后，得到的分子图是双星树。主要考虑双繁星的Wiener指标的极值问题，完全刻画了具有固定顶点数的双繁星的最小Wiener指标。
