摘要
运用升阶法研究几类高阶非线性微分方程,证明了它们均可由初等积分法求解。
This paper is concerned with the solutions of several classes of higher order nonlinear differential equations. By means of raising order, it is proved that the equations can be solved by differentiation. These results are generalizations of some known results.
