电阻液体在高电势下产生细丝和气溶胶的机制仍不清楚。对这种电流体动力 (EHD) 雾化模式的起始参数进行了实验研究。有关起始电位、毛细管半径、液体电导率和粘度影响的数据，以及观察到的电流-电压特性滞后现象，为首次提出的现象的定性模型提供了基础。产生气溶胶的液体流动可以根据表面应力张量来理解。
The mechanism by which resistive liquids subjected to high electric potentials produce a filament and aerosol is still not well-understood. An experimental study of the onset parameters of this electrohydrodynamic (EHD) atomization mode is presented. Data on the effect of onset potential, capillary radius, liquid conductivity, and viscosity, together with an observed hysteresis in the current-voltage characteristics, provide the basis for a qualitative model of the phenomena presented here for the first time. The flow of liquid that produces the aerosol is understood in terms of the surface stress tensor.
