通过后插参比电极的方法有效地消除了试验／参比电极之间的土壤介质电阻上ＩＲ降的影响，从而得到在高阻抗的土壤介质中真实反映金属电极极化行为的曲线，为运用电化学技术研究土壤腐蚀提供了一种新的手段．
The effect of IR drop on the soil medium resistance between the test / reference electrode is effectively eliminated by the method of inserting the reference electrode, so that the curve of the polarization behavior of the metal electrode in the soil medium with high impedance can be obtained. Electrochemical technology to study soil erosion provides a new means.
