摘要
本文阐明了鼓泡塔中液体循环的拟均相流体的概念．根据这一概念和前文（ＬｕｏａｎｄＳｖｅｎｄｓｅｎ１９９１）所建立的方法，提出了一个改进模型并讨了如何确定模型参数的方法，对于低粘性和高粘性流体，本模型的计算结果都与实测结果吻合较好．
This paper has clarified the pseudo-homogeneous fluid concept. Based on this concept,an improved model of liquid circulation has been proposed. The ways how to determine the model parameters are discussed. The velocity profiles calculated by the model are shown to agree well with reported experimental data both for low viscosity and high viscosity fluids.
