中文摘要：

本文从气泡微液底层的流动特性出发，利用Ｈａｌｌｉｎａｎ和Ｅｒｖｉｎ模型对微层蒸干的Ｓｔｒａｕｂ判据进行了理论分析，证实了临界蒸干半径与湿润性有关，同时指出微层蒸发中起关键作用的是膨胀压力而不是表面张力梯度。

英文摘要：

Using the Hallnan and Ervin's Model, the flow and evaporation in bubble microlayer was theoretically analyzed, and the dryout characteristics and Staub's criterion was discussed in detail. It was revealed that the critical dryout radius is associated with wettability of heated surface, and the dominant role in microlayer evaporation is disjoining pressure, not surface tension gradient.
