摘　　要：本文采用空气-富氧水物系,测定了矩形喷射塔板的板效率。对多排罩体塔板的流动状况进行了分析,并考察了液体旁路、液体提升量、罩体的排数等因素,从理论上推导出板效率的数学模型,所得计算值与实验结果基本吻合。Efficiency of rectangle jet plate is determined by using air-rich oxygen water system. Analyzing the flow state of multi-row of cap units and investigating the factors of liquid bypassing, quantity of liquid raised, row number of cap units and so on, the mathematical model of plate efficiency is derived theoretically. A good agreement between calculating and experimental values is found.
