摘要：

In this paper,sharp upper bounds for the Laplacian spectral radius and the spectral radius of graphs are given,respectively.We show that some known bounds can be obtained from our bounds.For a bipartite graph G,we also present sharp lower bounds for the Laplacian spectral radius and the spectral radius, respectively.
