文摘In this paper, by means of Lyapunov function and making use of the Browder's and the Brouwer's fixed point theorem, We study the problem of periodic solution about the higher order, nonautonomoas nonlinear periodical systems and obtain some sufficient conditions which guarantee the existence of periodic solution.
