In section 3, the author discusses some relationships among the separabilities and the almostperiodic and asymptotically almostperiodic solutions of almostperiodicsystem.
在§3中,研究一般概周期系统,讨论了其概周期解和渐近概周期解与分离性之间的某些关系。

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