摘要：

In this paper, we study the multiplicity of periodic solutions of a Duffing equation x '' + g(x) = p(t). By using the generalized Poincare Birkhoff fixed point theroem, we prove that this equation has infinitely many periodic solutions provided g satisfies a kind of integral condition and the related time map satisfies oscillating condition.
