对函数组引入仿射线性相关的概念,讨论了它的若干性质,在此基础上用仿射线性相关描述了非齐次线性常微分方程解的结构.
In this paper,we introduced the concept of affine linear dependence on the group of function,discussed some properties of them,and described the structure of the solution of non homogeneous linear ordinary differential equation by the affine linear dependence.
