本文中,我们通过利用平均化方法,将非自治常微分方程转化成自治方程,刻画了其平均化过程,得到非自治方程的平均化方程,而且利用Henstock-Kurzweil积分,建立了Carathéodory方程的周期和非周期的平均化定理.
In the paper, we can transfer the non-autonomous ordinary differential equation into autonomous equation by using the averaging methods, so the process of averaging is described and the averaging equation of non-autonomous equation is obtained.Furthermore, by using Henstock-Kurzweil integral, both periodic and non-periodic averaging theorems for Carath′eodory equations are established.
