The main theorem proved in this work is: Let M be a compact Riemannian manifold withnon-negative Recci curvature, then the first eigenvalue -λ1, of the Laplace operator of Msatisfies λ1≥π2, where d denotes the diameter of the M. This estimate improves the recentresults due to S. T. Yan and P. Li and gives the best estimate for this kind of manifold
