模型中采用传质、传热速率方程表征实际塔板上的传递过程，避免了级效率的计算。
Mass and energy transfer rate equations are used in describing the transfer processes on real trays and thus the computations of stage efficiencies are entirely avoided.
为预测其影响规律，文内针对含有错流塔板且气相预混合的精馏塔，提出了气液返混发生时计算精馏效率的混合池模型。
In order to calculate distillation efficiencies with the entrainment of both vapor and liquid, a mixing cell model was developed.
