常系数线性非齐次微分方程组的初等解法

Primary Solution to Common Modulus Linearity Non-homogeneous Differential Coefficient Equation Groups

本文利用初等方法,直接得到两个未知函数的一阶常系数线性非齐次微分方程组的通解公式,该方法不涉及矩阵的特征值及线性非齐次微分方程组的通解结构,且易推广,因而具有显著的优点。

This paper takes advantage of the primary solution to have obtained directly a general solution formula concerning the first grade common modulus linearity non-homogeneous differential coefficient equat and t ion groups of the two unknown functions. This kind of method does not involve the matrix eigenvalue he general solution structure of linearity non-homogeneous differential coefficient equation groups. some obvious advantages, it is not difficulty to popularize.
