| 摘 要： | 研究了纯Ｆｅ在Ｈ_２ＳＯ_４中从活化态转变成钝化态的预钝化过程．建立并分析预钝化膜生长模型．发现在致钝初期，预钝化膜复盖处的周界曲线维数大于１，预钝化膜的生成以分形方式进行，其维数随钝化电位的提高而提高．这表明不同电位下生成的初期预钝化膜具有不同的结构，也说明了钝态具有耗散结构特征．

| Abstract: | An investigation on transient processe of active dissolution-passivation was carried out for Fe in H_2SO_4 media.Based on the model for the growth of the pre-passive film developed by the authors,a fractal dememsion(D_s) of the film was obtained.This D_s and the rates of the formation of pre-passive film inceases with the increase of passivation potential. |
