摘要
借助变量替换法 ,求导法则 ,提出适当的条件 ,论证一阶变系数非线性微分方程的两类方程是可积的 ,且给出通解的表达式 。
On the basis of variable substitutional method,this article attempts to seek laws and prove the integratability about two types of equation in non linear deformation coefficient first order differential equation and therefore suggests the expression of general solution.Result:broadening of some relevant literatures to some extent.
