摘要
利用全微分方程的条件 ,给出一类微分方程的积分因子及通解公式 ,得出几类全微分方程中未知函数所满足的微分方程 。
By means of the conditions of total differential equation,in this paper are given the integral factor and general solution of one kind of differential equation and are obtained the differential equations that satisfy the unknown functions in some of total differential equations, thus are found the unknown functions and their general solutions.
