摘　　要：在φ1(?)00试验塔上,以空气-水系统,对φ10大孔(?)板和V型棚板测定了不同工况下的漏液速率,并用多元线性回归拟合得到这两种塔板的漏液速率和气速下限的计算公式,还作了物性修正,可用于工程设计计算。The weeping rates for V-Grid trays and sieve trays with φ10mm holes are experimentally determined under various operating conditions in a φ1200mm column for the air-water system. The calculation formula for the rates and the lower limits of the operation vapor velocity, in which the physical properties have been modified, are obtained with multinomal regression method, and ths formula can be used in engineering design.
