| Abstract: | in this paper,we discuss some qualitative behaviour of the solutions of a Lienard equation,obtain some sufficient and necessary or sufficient conditions for the existence of the family of homoclinic,closed orbits,hyperbolic and elliptic sectors,and the boundedness of positive and negative semiorbits,and the intersection with the vertical isocline. |

| Keywords: | Homoclinic closed orbit hyperbolic sector elliptic sector |
