摘　　要：现有的溶液导电理论认为溶液总阻抗为容性.通过实验发现,高频时溶液阻抗会随频率增大而增大,而且溶液的电流滞后于电压.这些都与现有理论不符.本文修正了溶液导电模型,使之在低频端与原有理论一致,在高频范围与实验现象吻合.According to our experiment,at high frequency,the impedance of electrolyte solution increases with increasing frequency,and the electric current lags behind the voltage.These phenomena contradict the present conduction theory for electrolyte solution.In this paper,the theory is corrected in order to explain the high-frequency phenomena.
