摘要: 本文讨论了三类较为一般的具有三个非线性项的四阶方程零解的稳定,得到了零解稳定的充分条件,推广了文1与文5的一些相应结果。

Abstract: In this paper,we have discussed the stability of the zero solution of three kinds of more generalized four-order equations with three nonlin-ear terms.Sufficient conditions are obtained for the stability of the zero solution and corresponding findings in papers(1)and(5)are thus extended.
