摘　　要：The purpose of this paper is to study a general Lidnard type cubic system with one antisaddle and two saddles. We give some results of the existence and uniqueness of limit cycles as well as the evolution of limit cycles around the antisaddle for system （2） in the following when parameter al changes.The purpose of this paper is to study a general Lidnard type cubic system with one antisaddle and two saddles.
