标准推导出预测的稳定性，形成在薄液膜流过加热表面的干补丁。Hartley和Murgatroyd [1，2]的分析适用于等温膜，本文将其扩展到包括蒸汽推力和热毛细效应，并进行了数值计算，指出了典型的热水和液态金属膜中各种效应的相对重要性。结果表明，对于高润湿性的液体（例如液态金属），热效应在确定干斑的稳定性方面成为主导。
Criteria are derived which predict the stability of dry patches forming in thin liquid films flowing over a heated surface. The analysis of Hartley and Murgatroyd [1, 2], applicable to isothermal films, is extended to include the effects of vapor thrust and of thermocapillarity.Numerical evaluations are carried out that indicate the relative importance of the various effects in conjunction with typical heated water and liquid metal films. The results show that for liquids of high wettability (for example for liquid metals) the thermal effects become dominant in determining the stability of dry patches.
