摘要

构造了由平行圆柱形电极组成的电幕。单相交直流电压叠加产生驻波型电场。虽然每个粒子在一个受限的区域内表现出固定的上下运动，但在电极上观察到一个整体的扇形粒子运动模式。图案的形状随着施加的交流或直流电压或两者的电压而改变。悬浮粒子的电荷量测量表明，在接地电极上的悬浮粒子具有正极性，而在高压电极上的悬浮粒子具有负极性。

Fundamental study of the motion of charged powder particles by using electric curtain

The electric curtain consisting of a parallel cylindrical electrodes was constructed. An electric field of standing wave type was produced with superposition of both single-phase AC and DC voltage. Although each particle showed a stationary up-and-down motion within a confined region, as a whole fan-like pattern of particle motion was observed over electrodes. The shape of the pattern was changed with the applied voltage of either AC or DC, or both. The measurement of the amount of charge of suspended particles showed that the particles over grounded electrodes have a positive polarity and the particles over high voltage electrodes have a negative one.<>
