摘要
本文提出用密立根油滴仪同时测量粉尘的粒径和荷电量的方法，并对两种工业粉尘在离子荷电条件下粒径和荷电量的关系进行了测试和研究．将测试结果与荷电理论计算值进行了比较和分析．
A method of simultaneously measuring sizes and charges for dusts is proposed，and the relationship between sizes and charges is measured and researched for two kinds of in-dustrial dusts on the condition of ionic charging．Experiment results are analyzed and com-pared with theoretical calculation.
