运用显微摄像，配以计算机图像采集，摄取了大量画面，从乙醇电雾化物理过程的变化，得到其液体碎裂现象，不同于离心力、气动力、撞击力的液体碎裂。在库伦力的作用下，其液体拉成丝，它的直径不断拉细，直径拉到某定值，而后细丝断裂为长度几乎相等的圆柱，收缩成直径变化不大的液滴群，即单分散的液滴雾。
With the use of micro-camera, coupled with computer image acquisition, a large number of pictures were taken, and the liquid fragmentation phenomenon was obtained from the change of the physical process of ethanol atomization. Different from the centrifugal force, the aerodynamic force and the impact force, the liquid was fragmented. Under the action of Coulomb force, the liquid is pulled into filaments, and its diameter is continuously thinned, the diameter is pulled to a certain value, and then the filaments are broken into cylinders of almost equal length, and the liquid droplets shrink into small droplet groups with little change in diameter Monodisperse droplet mist.
