When studying membrane fouling, the increasing rate of suctionpressure 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。

The drop of suctionpressure which is caused by flowing obstruct of linked tube leads to serious influence to refrigerant density.
连接管的流阻造成吸气压力的下降，对工质密度产生严重影响；系统中残留的冷冻油，阻碍制冷剂的蒸发。

A positive suctionpressure on the main pumps usually is needed and is frequently supplied by booster pumps close to the tanks.
