The odd point of plane differential systems=-y+δx+axy+my2+ly2n+1,y=G(x), is studied. The sufficient condition of the nonexistence of limit cycles for the system is obtained by means of comparing theorem, analyzing devergence and variable substitution.
通过研究微分系统x=-y+δx+axy+my2+ly2n+1,y=G(x)的奇点，借助比较定理，将该方程与其对称的方程进行比较，并通过分析散度和变量代换，得到了该系统极限环不存在的充分条件。
