The spreading of a surfactant solution on a water film at first glance seems a trivial problem. However, in the last 30 years or so this has been shown to be anything like the case. There have been numerous studies which show that Marongoni driven fingering of the spreading surfactant front exists. In this paper this work has been reviewed and an attempt has been made to rationalise the results. The paper concludes with some recent observations of ours concerning the spreading of sodium dodecyl sulfate over relatively thick water films, 200 microm or less.

表面活性剂溶液在薄液膜上的铺展。

乍看之下，表面活性剂溶液在水膜上的铺展似乎是一个小问题。然而，在过去的30年左右的时间里，事实证明情况确实如此。已经有许多研究表明存在马龙尼驱动的铺展表面活性剂前沿的指法。本文对这项工作进行了回顾，并尝试使结果合理化。本文以我们最近对十二烷基硫酸钠在200微米或更小的相对较厚的水膜上的扩散的一些观察得出结论。
