Finally, we discuss almost periodicphenomena, and obtain some sufficient conditions which assure the unique existence and globally asymptotic stability of almost positive periodic solution.
最后讨论了概周期解现象，得出了概周期正解的唯一存在性和全局渐进稳定性的充分条件。

Boffins were busily filling in the blanks in the periodic table and probing unknown atomic phenomena (like radioactivity and bonding).
科学家们忙于填补元素周期表的空白、探索未知的原子现象(如放射性和键合)。
