摘　　要：推导出了液体并流塔板汽体不混合时具有雾沫夹带和漏液时的Ｍｕｒｐｈｒｅｅ板效率Ｅ（ＭＶ）计算式。在没有雾沫夹带和漏液条件下，该计算式可还原为文献［８］所推导的Ｅ（ＭＶ）计算式。同时，还讨论了Ｎ、Ｅ（ＯＧ）及λｏ等变量在一定范围条件下Ｅ（ＭＶ）随ｅｏ或ωｏ变化的关系，并提出由允许的板效率降低限值确定允许的ｅｏ或ωｏ，以及Ｅ＿（ＭＶ）￣ａ与Ｅ（ＭＶ）之间的相互换算。Abstract Equations are derived, giving the effect of entrainment and weeping on the murphree tray efficiency, E(MV), under conditions of unmixed vapor between the mixed pools and liquid flowing in the same direction on successive trays. In the absence of entrainment and weeping, the equations can be reduced to the equivalent equations in the preceding Papers. Using the present equations, the effects of entrainment and weeping on E(MV)、E(MV)/E(MVco-0) and are discussed.
