摘要
借助变换、交换变量位置等方法,可以把两类二阶非线性常微分方程转化为二阶常系数线性常微分方程,得到二阶非线性常微分方程的可积判据及其通积分,达到了拓宽其应用范围的目的.
This paper studied two kinds of two - order nonlinear differential equation. By means of variable substitution, it turned these nonlinear differential equations into two - order constant coefficient linear differential equation. Thus it gets reduction of integrals into common denominations and expands those differential equations＇ scope of uses.
