讨论了一种倾向于将胶体颗粒捕获在空气-水界面的静电过程。当粒子接近界面时，水中高电荷胶体粒子周围的离子云移动到一个半球内，这在能量上是有利的。这种效果可能会与先前提出的毛细管捕获机制相竞争或超过。
An electrostatic process tending to trap colloidal particles at an air-water interface is discussed. The displacement of the ion cloud surrounding a highly charged colloidal particle in water into one hemisphere as the particle approaches the interface is energetically favoured. The effects may compete with or exceed previously proposed capillary trapping mechanisms.
