In contrast to a soap bubble, an antibubble is a liquid globule surrounded by a thin film of air. The collapse behavior of an antibubble is studied using a high-speed video camera. It is found that the retraction velocity of the thin air film of antibubbles depends on the thickness of the air film, e, the surface tension coefficient σ, etc., and varies linearly with (σ/ρe)(1/2), according to theoretical analysis and experimental observations. During the collapse of the antibubble, many tiny bubbles can be formed at the rim of the air film due to the Rayleigh instability. In most cases, a larger bubble will emerge finally, which holds most of the volume of the air film.
与肥皂泡相反，反气泡是被一层薄空气膜包围的液滴。使用高速摄像机研究了反气泡的坍塌行为。根据理论分析和实验观察发现，反气泡薄空气膜的收缩速度取决于空气膜的厚度(e)、表面张力系数(\sigma)等，并且与((\sigma / \rho e)^{(1/2)})呈线性变化。在反气泡坍塌过程中，由于瑞利不稳定性，在空气膜边缘会形成许多微小气泡。在大多数情况下，最终会出现一个较大的气泡，它占据了空气膜的大部分体积。
