摘　　要：介绍一种粉尘浓度测量的新方法——电荷感应法。基于外环状电荷感应测量原理,设计了试验测量装置,建立了试验平台,对粉尘浓度与感应电流的关系进行了试验研究,试验结果表明:粉尘浓度与其产生的感应电流呈线性关系,关系式为| I_m|=4.15×10^(-4)(?)^(0.93)C;风速、粉尘粒径对电荷法测量粉尘浓度有影响,风速越大、粒径越小,产生的感应电流越大。A new measurement of dust concentration method - induced charge method is introduced.The experimental test device is designed and the experimental platform is established based on the principle of outer induced charge and the relationship between dust concentration and the induced current are researched.The experimental results showed that the concentration of dust has a linear relationship with the induced current,and the relationship forum is.The wind speed and dust particle size affect the measurement of charge.The faster wide speed and the smaller the particle size is,the greater the induced current is generated.
