Abstract: This paper discusses some second order nonlinear systems. By the method of average, some sufficient conditions for the existence of almost periodic solutions of nonlinear systems are given, which generalize the known ones. Two particular systems are presented to illustrate that our results are feasible and more general.

Key words: Almost periodic solution, Method of average, Eigenvalue.
