摘要：实验证明：由于在碱性介质 中钢筋表面存在钝化膜，使钢筋锈蚀过程的介电谱具有明显特征，因而从其Cole-cole图可以得到钝化膜的电容特性。 关键词：钢筋锈蚀 ；介电谱 ；Cole-cole图；腐蚀电容 Abstract：The characteristics of dielectric spectrum of rebar corrosion in mortar was studied．Due to presence of passivation film on the surface of rebar，a special shape of curve appears in the Cole-cole plots from which the capacitance of film can&n |
