英文摘要：

A novel approach is presented to prepare porous alumina templates, where the pores are generated parallel to the surface of the substrates, on the basis of analysis of the method and the process of anodic oxidation. This is through controlling the current in the alumina templates by applying magnetic field in the process of anodic oxidation. Generally, porous alumina templates are prepared by the two methods named one step anodic oxidation or two step anodic oxidation. The pores of the porous alumina templates, prepared by these two methods, are perpendicular to the substrates, which limits the applications in many fields. This novel approach can solve the problem mentioned above. We discuss the principle of the method and design the device in details.
