Supplemental aeration is strongly recommended .

补充曝气是极力推荐。

If infusing is only made without aeration , the effect is often poor .

如只浸泡不曝气，效果往往不佳。

Environment management and fisheries officers deployed aeration equipment to boost oxygen levels to save the remaining fish in the 55-acre lake

环境管理人员和渔业官员给这块占地55英亩的湖泊部署曝气设备，提高湖水含氧量以挽救剩下的鱼。

The experimental results indicated that the more the compartment number of aeration tank , the more powerful the driving force of biological reaction , and the higher the treat-ment efficiency and the limiting organic load .

试验结果表明，曝气池的分格数越多，其生化反应推动力越大，处理效率与极限有机负荷也越高；

The aeration of the room is bad .

这屋子通风真差。
