摘要
对三元一阶线性非齐次微分方程组x'=Ax+f(t)的解法进行深入讨论,提出"行向量"概念,并且利用该概念给出其方程组解的本质结构.
In this paper,the solution of first order linear inhomogeneous differential equations is discussed,the concept of ＂line vector＂is put forward,and the essential structure of the solution of the system of equations is given by using this concept.
