| Abstract: | In this paper,anthor has analysed the relative position between the stable manifold and the unstable manifold of the homochinic oribit of the autonomous system with melnikov function method,getting the conditions which the system bifurcates limit circles. At last, giving the conditions that the system occure Chaos and subharmohic oribits after periodic perturbations. |

| Keywords: | Melnikov method limit circles Chaos Subharmonic oribits |
