摘要
指出消除极化作用是提高电阻法测量精度的重要途径,从理论上分析了影响极化作用的诸因素,对极板面积、信号频率及电压进行了一系列试验与研究。结果表明:极板面积、信号频率及电压对测量精度有不同影响。
In this paper,the impor- tant way of increasing the accuracy in measuring the moisture by a resistant method with eliminating the polarization is introduced.In theory,the factors of effect on the polarization are analysed.A series of experiments and studies are carried out on electrode area,signal frequency and voltage have different inrlune,on measuring accuracy.
