The water flow velocity in the suction pipe, which is crucial for evaluating the performance on pumping fish, can be measured by the pumped water flow rate of the riser in an air lift pump system.

气力提升泵的水输送量反映了提升管进口的流速情况，而进口流速是衡量吸鱼效果的重要因素。

When studying membrane fouling, the increasing rate of suction pressure of membrane was used to evaluate the membrane filtration characteristics of membrane bioreactor process.

在研究膜污染时，实验采用膜抽吸压力的上升速率表征运行过程中膜过滤性能的变化。

Therefore, how to determine the right gas flowing rate and flue suction to stabilize the flue temperature and make the coke oven burning in the optimal status is the most cr.

火道温度是影响焦炉燃烧过程的重要参数，如何确定煤气的流量和烟道的吸力，使焦炉处于最优的燃烧状态，是进行焦炉火道温度控制的关键性问题。
