实验表明提高温度（Ｔ）能大幅度增加挥发性物质在气态膜过程中的传质系数（Ｋ），Ｋ和Ｔ间的关系符合Ａｒｈｅｎｉｕｓ方程Ｋ＝Ｋｏｅｘｐ（－Ｅ／ＲＴ）．用Ｓｔｏｋｅｓ－Ｅｉｎｔｅｉｎｓ和Ｌｅｖｅｑｅ方程，从理论上证实：（１）对于易挥发性物质（如ＨＣＮ），温度主要是通过降低进水边界层中水溶液的粘度或提高扩散系数，而使传质系数大幅度升高；（２）对于挥发性较小的物质（如苯酚），温度主要是通过提高其蒸汽压或进水边界层和膜微孔中气相间的分配系数（Ｈ）而使传质系数大幅度的提高．
Experiments show that increasing the temperature (T) can greatly increase the mass transfer coefficient (K) of volatile substances in the gaseous film. The relationship between K and T accords with Arhenius equation K = Koexp (-E / RT). Using Stokes-Einsins and Leveqe equations, it is theoretically proved that: (1) For volatile materials (such as HCN), the temperature is mainly caused by decreasing the viscosity of the aqueous solution in the influent boundary layer or increasing the diffusion coefficient, (2) For less volatile materials (such as phenol), the temperature is mainly caused by increasing the partition coefficient (H) of the vapor pressure or the gas phase between the water infiltration boundary layer and the membrane pores, so that the mass transfer coefficient A substantial increase.
