分离压力近似为Pd =− A <$δ− 3的吸附控制润湿膜的线间区域的平均蒸发传热系数可以表示为kh = h id [1− O. 5（η− 1+ η− 2）]。hid是理想的液-汽界面传热系数，η是系统的物理性质和线间区域范围的函数。提出了一种求取传热系数的简便方法。该系数在相对短的距离上从中间线处的零变化到等于液-汽界面传热系数的值。
The average evaporation heat-transfer coefficient for the interline region of an adsorption controlled wetting film in which the disjoining pressure is approximated by P d=− A ̄ δ− 3 can be represented bykh= h id [1− O. 5 (η− 1+ η− 2)]. h id is the ideal liquid-vapor interfacial heat-transfer coefficient and η is a function of the physical properties of the system and the extent of the interline region. A simple procedure to obtain the heat-transfer coefficient is presented. The coefficient varies from zero at the interline to a value equal to the liquid-vapor interfacial heat-transfer coefficient over a relatively short distance.
