土壤金属界面水膜测量的浓差极化方法

Concentration on Polarization Rule of the Water Film Between Soil and Metal Interface

摘要: 利用在阶跃电压作用下土壤水分中水溶性氧粒子放电的电化学反应过程，首次完成了土壤—金属界面水膜面积与厚度的测量。理论及实验均证明了此方法用于界面水膜测量的可靠性及准确性。

Abstract: In this paper the concentration polarization rule of dissolved oxygen in the interfacial water film was studied during the electrochemical reaction.An electrochemical method of measuring the interfacial area and thickness was put forward. The measuring results showed fully the effectiveness and reliability of this method.
