一阶非线性微分方程的常数变易法

NON-LINEAR ORDINARY DIFFERENTIAL EQUATION OF FIRST ORDER WITH METHOD OF LEADING VARIABLES

常数变易法求解一阶微分方程是作为求解一阶线性方程的解法给出的，本文对非线性方程两次使用常数变易法求解，并对贝努利方程、黎卡提方程进行求解探讨．

Method of leading variables is method of solving linear ordinary differentialeqUatio of first order. The writer rePeatedly uses method of leading variables for non - linearowhmp differential eqUahon of first other,and stUdies Bemoulli and foccai eqUation in theParer.
