电帘由一系列的连通交流电源的平行电极组成，在清除月球、火星表面或外空间中的尘埃颗粒方面具有潜在的应用前景。连接多相交流电的电帘叫做行波电帘。本文研究了模拟火星灰颗粒在行波电帘中的运动传输模式，测量了颗粒在行波电帘中的宏观输运速度，发现电压对颗粒传输速度影响较大，并提出中频区间是行波电帘的理想操作条件。
The electric curtain, consisted of a series of parallel electrodes, has received much attention because of its potential benefits from cleaning or mitigating dust in Moon, Mars and terrestrial environments. The technology which is excited by a multi-phase AC voltage source is called as travelling electric curtain. This research identified the different moving modes of dust particles on travelling electric curtain and measured the macro transport velocity of dust particles. The results indicate that the voltage has a great effect on the particle moving velocity and the medium frequency has a better performance for particle removing.
