请教如何翻译? a once-through thermosiphon reboiler was starved of liquid because the overflow weir of the trapout pan feeding the reboiler was level with a seal pan weir. liquid bypassed the trapout pan. problem was solved by raising trapout pan weir by 6 in. 请教该如何翻译,特别是里面设计到的trapout pan 和seal pan都是指什么呢? 谢谢 查看更多
