摘　　要：建立了气泡传质的新的数学模型。与原有的诸模型相比，新模型更接近气泡传质的实际情况，得到了与实验关联式基本一致的传质系数表达式，为在实际中改善传质效果提供了理论依据。A new model for mass transfer of air bubble in water is established. Comparing with the other models, the new model is closer to real status and the expression of mass transfer factor is obtained, which coincide with that obtained by experiment and lays a foundation for improving the mass transfer effect in actual use.
