dictate 是啥意思尼? 这是工艺叙述： 原文： the lights column overheads are condensed against cooling water in the lights overhead condenser. the condensate and any uncondensed lights are separated in the lights column reflux drum。 the uncondensed gases, air in-leakage saturated with methanol, dictate the organics load on the vacuum pump. ..........................（隔了一段） .....................the liquid and vapour mixture from this exchanger then passes to the heavies overhead trim condenser which sub-cools the uncondensed gases, air inleakage saturated with organics, to reduce the load on the vacuum pump . 大家再看看，dictate是什么意思更准确。跟“reduce"相对，能不能译成“产生了、增加了”泵的负荷。查看更多
