摘　　要：文章中给出了树的最大Laplace特征值等于树的顶点数时树的结构特征,并且从证明过程中得出了一系列关于树的Laplace特征值上界估计的结果。In this paper, we provide all extreme trees which satisfy the situation that the largest Laplacian eigenvalues are equal to the number of vertices. Moreover, we get a series of other results from the above proof. All the resuits characterize trees with n vertices.
