摘要
周期系数二阶线性方程的稳定性由其特征指数确定,本文给出一种由系数直接估计特征指数的方法,简单且实用.
The stability of two order linear differential equation with periodic coefficient is determined by its characteristic exponent. In this paper, we give a method of estimating characteristic exponent by the coefficient. The method we give is simple and usable.
