摘　　要：提出对半对数极化曲线进行微分的方法，得到的微分极化曲线及其特征参数可以更精细地表征缓蚀剂的阳极脱附行为．A differential polarization curve method and its application in the investigation of the anodic desorption behaviors of interface corrosion inhibitor were proposed and expounded. Some parameters, such as E s (the desorption onset potential ), E p (the desorption peak potential) , E f (the desorption completion potential) and des (the average desorption speed), were defined and calculated according to the differential polarization curve. Further more, the variation of the desorption speed during the desorption process can also be described by the differential polarization curve.
