摘　　要：给出了多项式微分系统的反射函数第一分量不依赖于第二变量的的充要条件,并应用所得结论研究了周期多项式系统周期解的几何性态.We established the necessary and sufficient conditions for that the first component of reflective function of the polynomial differential systems does not depend of the second variate. The results are applyied to discuss the geometric property of the periodic solutions of the polynomial differential systems.

关 键 词：多项式系统 反射函数 周期解
