摘要
运用变量变换的方法将一些特殊类型的一阶微分方程化为了可分离变量的齐次方程、伯努利(Bernou lli)方程或标准的一阶线性微分方程,从而可用初等解法来解这类一阶微分方程.
The method of variable quantity transformation is used to transform some special kinds of first-order differential equations into separable equations of homogeneous equations,Bernoulli equation or standard first-order linear differential equations,thus the primary methods can solve these first-order differential equations.
