摘要
针对二阶常系数非齐次线性微分方程求特解的现有方法的局限性,提出常数变易法求二阶常系数非齐次线性微分方程的特解的方法,并给出四个求特解的公式。
According to the limitation of the present method to the particular solution of second order nonhomogeneous linear differential equation with constant coefficients, the method of variation of constant was given,in order to solve the general problem of particular solution of second order nonhomogeneous linear differential equation with constant coefficients, then four formulas were also presented to solve the particular solutions.
