在聚结之前，各种液体的液滴可以在相应的表面上漂浮延长的时间段。探讨了高纯水中延迟聚结的特性。直径为几毫米的液滴从喷嘴释放到水面上。结果表明，液滴的漂浮时间高达数百毫秒。当液滴确实合并时，它们以逐步的方式合并，在合并期间穿插着静止期。足足走了六个台阶，这滴水滴才消失。液滴被释放在一个系列中，这允许检测意外的突然浮动时间的变化，在整个系列的持续时间。静电荷、液滴大小和侧向运动等因素对液滴寿命有相当大的影响，压力降低也会减少聚结所需的步骤数。根据目前的观察和最近的报告，一个可能的机制，非聚结被认为是。
Droplets of various liquids may float on the respective surfaces for extended periods of time prior to coalescence. We explored the features of delayed coalescence in highly purified water. Droplets several millimeters in diameter were released from a nozzle onto a water surface. Results showed that droplets had float times up to hundreds of milliseconds. When the droplets did coalesce, they did so in stepwise fashion, with periods of quiescence interspersed between periods of coalescence. Up to six steps were noted before the droplet finally vanished. Droplets were released in a series, which allowed the detection of unexpected abrupt float-time changes throughout the duration of the series. Factors such as electrostatic charge, droplet size, and sideways motion had considerable effect on droplet lifetime, as did reduction of pressure, which also diminished the number of steps needed for coalescence. On the basis of present observations and recent reports, a possible mechanism for noncoalescence is considered.
