In this paper we use the reflective function of Mironenko to study the fact that the perturbed differential equations are equivalent to the polyno-mial differential equations, and also consider the polynomial differential equations with continuously.
本文应用Mironenko的反射函数方法来研究了微分方程与其扰动方程之间的等价关系,考虑了微分方程是多项式微分方程的情形,其中多项式的系数函数都是连续可微的。
