The asymptotic behavior of nonautonomous Lotka-Volterra systems is studied in this thesis which consists of three chapters.

In Chapter 4 we study the asymptotic behavior of solution for the weakly dampednonlinear Schrodinger equation in a bounded domain 〓.

第五章研究具有几乎周期外力的非自治Ginzburg-Landau方程的吸引子及其维数。

We gain conditions for persistence for three-species of the system and global asymptotic stability for positive periodic solution of the system.

研究了一类具有扩散系数和 Holling 类功能反应的一捕两食三种群非自治捕食系统，得到了系统持久生存和周期系统存在唯一全局渐近稳定的周期解的条件。

In this paper,by using the comparison theorems and constructing suitable Lyapunov function, the sufficient conditions are obtained for the permanence and existence of globally asymptotically stable positive periodic solution of the system.

研究了具有反馈控制的n种群非自治周期竞争系统的持续性，利用微分不等式并构造适当的Lyapunov函数得到系统存在惟一、全局吸引的正周期解的充分条

With the help of comparison theorem, sufficient conditions which guarantee permanence of the system are obtained. For the almost periodic case, by constructing a suitable Liapunov function, we obtained that the system has a unique globally asymptotically stable positive almost periodic solution. Finally, we study a multispecies predator-prey system with stage structure and Holling II type functional response.

And one of the most significant principles of Realty Service is autonomy or autonomic management.

就物业管理而言，最重要的原则应当是"自治管理"。

After more than twenty years of development,the villagers' autonomous system of our country has obtained tangible result.

我国的村民自治制度在经历了20多年来的发展后，已取得了明显的成效。
