| Abstract: |
| Associated with the variational systems of non-perturbation systems, a kind of almost periodic perturbation system with deviating argument is investigated by using the contraction mapping principle. A set of sufficient conditions for the existence and uniqueness of the systems is obtained. |
| Key words: differential systems perturbation systems almost periodic solutions uniqueness |
