结果表明，截留可以解释上升气泡收集的细菌数量。在上升的前几厘米，由于气泡表面是可移动的，所以收集率很大。当气泡吸收表面活性物质时，其表面失去流动性，收集率降低。头20-30厘米的上升是最重要的。在之前的一篇论文中(Blanchard等人，1981)，我们证明了由破裂的气泡产生的喷射液滴中的细菌是气泡上升时被气泡清除的结果，我们这里的目的是表明拦截(Weber 1981)是负责由上升的气泡收集细菌的机制。上升的气泡收集的颗粒
It is shown that interception can account for the number of bacteria which are collected by a rising bubble. In the first Few centimeters of rise the collection rate is large because the bubble surface is mobile. As the bubble picks up surface-active materials, its surface loses mobility and the collection rate decreases. The first 20-30 cm of rise are the most important. In a previous paper (Blanchard et al. 1981), we showed that the bacteria in the jet drops produced by a bursting bubble were the result of scavenging by the bubble during its rise, Our purpose here is to show that interception (Weber 1981) is the mechanism responsible for the collection of bacteria by a rising bubble.
