对多孔阳极氧化铝和钛氧化物进行了研究。提出了一个等场强模型来解释孔洞的形成及其有序性的自调节。高分辨电子显微镜分析表明，阳极氧化钛纳米管具有双层结构。研究还表明，多孔阳极氧化膜的孔隙率主要取决于水的相对解离速率。
Porous anodic aluminium and titanium oxides are investigated. An equifield strength model is proposed to explain the formation of the pores and their self-adjustment of ordering. High-resolution transmission electron microscopy analysis revealed a double-layer structure in the anodic titanium oxide nanotubes. It is also shown that the porosity of the porous anodic oxide film is mainly governed by the relative dissociation rate of water.
