摘要：
本文研究了因特定表面活性剂存在而表现出极高刚性的表面下，泡沫薄膜破裂动力学这一经典问题。研究报道了两个新特征：首先，观测到与著名的Taylor-Culick定律存在显著偏差；其次，薄膜中可观察到类裂纹图案，且这些图案出现在一个明确的形变点上。研究定量探究了表面活性物质对这些特征的关键作用，指出表面弹性对描述这些快速动力学过程的重要性，从而提供了一种在极远离平衡条件下表征表面弹性的替代工具。文中还讨论了裂纹的起源及其对薄膜破裂动力学的影响。
英文摘要：
The classical problem of foam film rupture dynamics has been investigated when surfaces exhibit very high rigidity due to the presence of specific surfactants. Two new features are reported. First a strong deviation to the well-known Taylor-Culick law is observed. Then, crack-like patterns can be visualized in the film; these patterns are shown to appear at a well defined deformation. The key role of surface active material on these features is quantitatively investigated, pointing the importance of surface elasticity to describe these fast dynamical processes, and thus providing an alternative tool to characterize surface elasticity in conditions extremely far from equilibrium. The origin of the cracks and their consequences on film rupturing dynamics are also discussed.
