荷电雾滴电荷衰减规律研究

CHARGE ATTENUATION PATTERN OF CHARGED DROPLETS

分析了雾滴的荷电及电荷泄漏,并利用荷质比测定装置测定了远距离处群体荷电雾滴的荷质比,建立了荷电雾滴的电荷衰减数学模型。

This paper analyses the charging and the charge leaking of droplets, measures the ratio of charge to mass of population droplets at distant spots, and showes that the charge will attenuate as time or distance increases and that the droplets still carry charge at distant spots. Then this paper establishes the mathematical model of charge attenuation of charged droplets, and showes that the qM rises as the charging voltage increases and the droplet diameter decreases, and the qM goes down in a lower rate as the distance increases.
