The results indicated that the range of the interline region was quite small in the total extended meniscus region,nevertheless the variation of its surface temperature was much obvious,implying that the resulted Marangoni effect could cause great "pump" force to drive the film flow,which may be the main contribution of the interline region to the total extended thin film evaporation.

分析结果表明，过渡薄液膜区域占整个延展弯月面区的比例很小，但气液界面的温度变化非常明显；薄液膜过渡区对传热的主要贡献不在于增加总换热量，而是通过界面温度变化产生的Marangoni效应，对整个液膜区域的流动产生显著的"泵吸"作用。
