摘　　要：A new parameter iteration technique is proposed to solve the Duffingequation with strong and high order nonlinearity. Contrary to the linearized perturbation technique parametrized perturbation technique and variational iteration techniqueproposed by J.H. He, the frequency converged asymptotically to the exact result, not aconstant.A new parameter iteration technique is proposed to solve the Duffingequation with strong and high order nonlinearity.
