摘 要: | In this paper,it is obtained that a periodic system has an almost periodic solution ifit has a solution x=(t)uniformly stable with respect to Ω_,and has a periodic solutionif x=(t)is weakly uniformly asymptotically stable with respect to Ω_.Meanwhile,it isalso obtained that a uniformly almost periodic system has an almost periodic solution if ithas a solution x=(t)uniformly asymptotically stable with respect to A_~f
