摘要
以虚拟循环模型为基础，提出了一个考虑滞止区影响的模型，并导出了板效率的解析表达式。与同类模型相比，不仅计算方法简单。
This paper develops a new model of distillation tray efficiency including the effect of the stagnant region on a tray,based on the previous pseudo circulation concept It is an analytical expression with better agreement with experimental results
