非线性系统的长期规则运动除了平衡点和周期解以外，概周期解，或有时表现为拟周期解也是一种长期规则运动。

Besides the equilibrium and periodic solution, the almost periodic solution, which sometimes appears as quasi-periodic solution, is also a long term regular motion of nonlinear system.

本文主要讨论几类非线性方程的(拟)概周期解和(渐近)概自守解的存在性。

In this thesis, we discuss mainly the existence of (pseudo) almost periodic solutions and (asymptotically) almost automorphic solutions for some nonlinear equations.
