摘要
本文借助于对lienard方程的研究方法，研究一类由lienard方程耦合而成的三阶非线性微分方程零解的全局稳定性，得到了比较简洁的判别条件。
This paper disuss global Asymptotic stability of the trivial solution of the nonlinear differential equation of order three Composed of lienard equstions By the help of the studied methods for lienard equation, we obtaina sempler sufficient condition.
