摘要
常数变易法是求解非齐次线性微分方程行之有效的一种方法,利用求解一阶非齐次线性微分方程的常数变易法的思想,推广到一般的三阶非齐次线性微分方程的情形,得出通解公式,并通过实例进行验证。
Constant variation method is an efficient solution to nonhomogeneous linear differential equation,Using constant variation method of first order nonhomogeneous linear differential equation,Which has been generalized to three order nonhomogeneous linear differential equation,Conclusion the general solution formula and validated by an example.
