| 摘 要： | 运用向量Ляпунов函数法,对线性系统、非线性系统的稳定性已经有了一些研究,但对于它们解的模之估计却不多见。Wazewski曾就变系数线性系统,给出了一个解的模之估计。本文运用向量Ляпунов函数法和Wazewski的方法,在文1,2,3]的基础上对一类非自治非线性系统给出其解的模之估计,并给出了一类非自治非线性系统零解不稳定的充分条件,举出了应用实例。

| Abstract: | There have been some researches1,2,3] on stabilityof linear system and nonlinear system by means of vector Lyapunovfunction. But, that are seldom seen as concerns modular estimationof thier solutions. For linear system with variable coefficients,Wazewski given an modular estimation of its solution4]. By vectorLyapunov function method and Wazewski'samethod, this paper givesan modular estimation of the solution and the sufficient conditionsthat the zero solution is unstable, both of a type of nonautonomousnonlinear system based on papers1,2,3]. Two examples are given. |
