高阶线性微分方程理论中的两个新结论

摘要

利用线性代数中有关行列式的知识以及微分方程与方程组之间的转化方法，得到相关的两个新结论，不但丰富了这一模块的理论内容，也填补了其实用性不足的缺陷。%Two new conclusions are obtained based on the knowledge of determinant and the conversion between differential equations in linear algebra. Thus, the theory of the module is enriched and the practicability is furthered.
