摘要：

In the present paper, without Riissmann's nondegenderate condition we show the persistence of KAM invariant tori. Using this theorem we obtain the persistence of invariant tori for degenerate systems rising from restricted three-body problems, especially, for Lagrange equilibrium position L2 with certain degeneracy.
