摘　　要：通过对扇(Fn)及其一致膨胀图(UFFn)的结构特征进行研究,得到其结构具有一定对称性.根据图的PI指数的定义,给出了扇及其一致膨胀图的PI指数.The structural features of fans （ Fn ） and uniform inflations of fans （ UFFn ） were studied, the structures of fans and uniform inflations of fans were showed symmetric to some extent. According to the definition of PI indices, the PI indices of fans and uniform inflations of fans （ UFFn ） were presented.
