%X Hamiltonian System is an important model of differential equation.In this paper,the author investigates the existence of periodic solution for nonautonmous Hamiltonian System with sublinear nonlinearity by saddle point theorem in critical point theory.Some sufficient conditions for the existence of periodic solutions are obtained,and the results improve the Ahmad-Lazer-Paul’s coercive condition.
