| Abstract: | The existence of periodic solutions for non-automous second order systems at resonance is investigated.With the sub-linear increase of the non-linear term,the periodic solutions of the system are converted into the critical points of a functional defined on a proper space，and the existence of periodic solutions is proved through the critical point theory. |

| Keywords: | non-autonomous second order systems critical point theory periodic solutions resonance critical point |
