1. 抽气：泵激电压 pump voltage | 抽气 pumpdown? | 抽运能量 pumping energy
2. 抽水：pumpcretepipe泵送混凝土管 | pumpdown抽水 | pumpedstorage抽水蓄能
3. 泵送作业：pumpdown perforator 泵送射孔器 | pumpdown 泵送作业 | pumped-off well 空抽井
4. 抽空降压：pumpdown 抽空 | pumpdown 抽空降压 | pumphouse 泵室
1. Capture water vapor and cut pumpdown time by as much as 75% in high-vacuum systems
在高真空系统中抽吸水汽，缩减抽空时间多达75
2. Cryocondenses water vapor in vacuum systems, High-vacuum pumpdown time cut by 25% to 75
在高真空系统中抽吸水汽，缩减抽空时间多达75
3. In solution polymerization, the reaction rate increases with the increasingof the reaction temperature; The numerical average molecular weightincreases with the increasing of the reaction temperature, reaction time and pumpdown time.
从X射线衍射峰的变化可以看出，在所得的产物中，PA12T的结晶度最高，均聚 PA12工最低，为透明非晶态聚合物；共聚酞胺随着PA12工的含量的增加，其结晶度逐渐降低。6。
