    扩展双星树（T（n）n1，n2）是 n－1长路径的两端点分别联结 n1条悬挂边和 n2条悬挂边所得到的图。论文根据扩展双星树的结构特征，研究了扩展双星树的类Wiener指数，给出了一般计算公式。

    The double star graph T(n)n1 ,n2 is a kind of graphs that includes a path whose length is n-1 and two ports with n1 and n2 pendant edges separately .This paper studys the similar Wiener index of the double star graph based on its structure and gives the computational formula of Wiener‐E index and Wiener‐O index for them .
