摘　　要：运用不可逆热力学原理 ,对气泡传质过程进行了理论分析 ,讨论了非稳态、稳态、平衡态的差异及其变化规律。根据实验结果 ,提出了近界面浓度与两相相对运动速度的关系式。对气泡传质过程的近界面浓度场进行了模拟计算 ,计算结果与实验结果相当吻合。The theoretical analysis on bubble mass transfer process was made by the non reversible thermodynamics.Non steady state,steady state and equilibrium state and changing regulation were discussed.A relation of concentration near interface to flow velocity was proposed.Numerical simulation on the concentration field near gas liquid interface was made,and the results were in well accordance with the experimental ones.
