Uniformly Asymptotic Stability and Existence of Periodic Solutions and Almost Periodic Solutions

<正> We introduce the concepts of uniformly stable solutions and uniformly-asymptotically stable solutions, and then give the relation between Lyapunov function and those concepts. Furthermore, we establish the theorem that an almost periodic system or periodic system has uniformly-asymptotically stable solutions and Lipschitz' condition has an almost periodic solution or periodic solution.
