摘要
通过变量代换法将几类变系数微分方程化为常系数方程,并给出化为常系数方程所应满足的条件。
This article changes several kinds of variable coefficient differential equation into constant coefficient equation through the variable substitution method and gives the condition which the constant coefficient equation to be changed into should satisfy.
