摘　　要：依据液体混合池模型，推导出液体并流塔板具有汽相夹带时的、Ｅ＿（ＭＶ）及／Ｅ＿（ＭＶ）等板效率计算式。并在几种特殊情况下，简化为文献报道的Ｌｏｃｋｅｔｔ、Ｄｒｏｇａｒｉｓ等人、张东平等人及本文作者所提出的板效率计算式。讨论了λ＿ｏ、Ｅ＿（ｕＧ）、Ｎ等参数在一定范围条件下、Ｅ（ＭＶ）、／Ｅ＿（ＭＶ）随汽相夹带分率的变化关系。The Present PaPer,using the mixed-pool model for liquid mixing ,suggests mathematical models of,E_(MV)and E_(MV)under conditions of liquid flowing in the same directionon succesive trays in the presence of vapor entrainment.For special cases,the present mathematical relationships can be simplified to equationsidentical with those published in the literatnre.Using the present mathematical relationship, the effects of vapor entrainment on,E_(MV) and E_(MV)are discussed.
