We investigate the fluctuating pattern created by a jet of fluid impingent upon an amphiphile-covered surface. This microscopically thin layer is initially covered with 50 microm floating particles so that the layer can be visualized. A vertical jet of water located below the surface and directed upward drives a hole in this layer. The hole is particle-free and is surrounded by the particle-laden amphiphile region. The jet ruptures the amphiphile layer creating a particle-free region that is surrounded by the particle-covered surface. The aim of the experiment is to understand the (fluctuating) shape of the ramified interface between the particle-laden and particle-free regions.
我们研究了一股流体射流冲击两亲分子覆盖表面时产生的波动模式。这个微观层面的薄层最初覆盖着50微米的漂浮颗粒，以便该层能够可视化。位于表面下方并向上喷射的垂直水流在这个层中冲出一个洞。这个洞没有颗粒，被充满颗粒的两亲分子区域包围。水流冲破两亲分子层，形成一个没有颗粒的区域，该区域被颗粒覆盖的表面所包围。该实验的目的是了解充满颗粒区域和无颗粒区域之间分支界面的（波动）形状。
