摘要
文中推导出Ｌｅｗｉｓ的第二、第三种情况下．即塔板上液体为活塞流、板间汽相不混合时，具有漏液的汽相Ｍｕｒｐｈｒｅｅ板效率ＥＭＶ计算式．在没有漏液条件下．分别还原为相应情况下的Ｌｅｗｉｓ推导的板效率计算式．讨论了Ｅ．λ０等变量在一定范围条件下ＥＭＶ，ＥＭＶ／ＥＭＶ，β０＝０等随漏液率β０的变化关系，以及ＥＭＶ与表观板效率ＥＭＶ之间的相互换其．
Equations were derived giving the effect of weeping on the Murphree tray efficiency (EMV) for Lewis' case 2 and 3, when the liquid on the tray is in plug flow and the vapor is unmixed between trays. In the absence or weeping(β0= 0), it can be reduced to the equivalent equations or Lewis. Using the present equations, the. effect of weeping on EMV and EMV/ EMV,β0=0, in addition to the relational expression between and EMV, were discussed.
