false downcomer 该翻译成什么降液管? http://.sg/qms/cog/og-011a2.htm 对false downcomer和weir的解释,一个强调分布器的功能,一个强调保持液位的功能: false downcomer: a false downcomer is usually used to distribute liquid on a tray. weirs: weirs act as dams on the tray and establish liquid levels across the tray or in a seal pan. they may be on the inlet, the outlet or on both sides of the tray. jet trays do not have outlet weirs. 鉴于此,既然false不好译出,false downcomer也可以选择 下降管 下注液分布管 等区别于“降液管”的名称吧查看更多
