The result shows that the anodic alumina membranes produced in oxalic acid or phosphoric acid electrolyte are porous double-layer films. 在硫酸电解液中形成的直流阳极氧化铝膜的等效电路中无多孔层信息。
Experiments indicate that acetone exhibits the best degreasing effect and that well-arranged porous anodic alumina film is obtained without annealing and electropolishing. 实验结果表明，采用丙酮除油效果最好，不经高温退火和电化学抛光仍能得到高度有序的多孔阳极氧化铝膜，使制备工艺得到了简化。
