摘　　要：利用锥上的不动点定理,研究一类非线性中立型方程的概周期解,得出保证方程存在正概周期解的一组充分条件.With respect to the almost periodic solutions to some neutral nonlinear equations,a study is made of their existence by means of the fixed point theorem in the cone.Sufficient conditions are given to the almost periodic solutions of these equations for ensuring their existence under some assumptions.

关 键 词：中立型方程 锥上的不动点定理 概周期解
