我们给出了在声频范围内经历大振幅简谐振荡的单个圆形肥皂膜的强烈非线性行为的观测结果。在这样的薄膜中，液体向其中心重新分布，这导致冲击模式的形成，从而导致液滴从薄膜中喷射出来。液体再分配和液滴喷射这两个过程最终都会导致薄膜破裂。
We present observations of the strongly non-linear behaviour of a single circular soap film undergoing large-amplitude harmonic oscillations in the acoustic frequency range. In such a film, liquid is re-distributed towards its centre, which leads to striking mode formations and consequently to the ejection of droplets from the film. Both processes, liquid re-distribution and droplet ejection, finally result in the rupture of the film.
