摘　　要：In this paper, we discuss the complex isochronicity of a sixth degree polynomial system. We first adopt a new algorithm to find necessary conditions for complex isochronicity, then prove the sufficient conditions using effective methods.In this paper, we discuss the complex isochronicity of a sixth degree polynomial system.
