中文摘要：

经由阳极化的系统的调查有图案并且 unpatterned 标本，关于毛孔尺寸的显著差异的现象，毛孔密度和毛孔蚀刻率被证实。把显微图和当前电压的曲线基于扫描电子显微镜(SEM ) 的详细分析，在物理、化学的元素之间的比赛被发现对理解观察关键。结果显示毛孔的尺寸，密度和生长速度可以充当样品表面的起始的形态学的明显的功能，尽管有空间费用区域的将近固定的宽度。象 current-burst-model (CBM ) 一样的电场的效果被采用解释内在的机制。

英文摘要：

Via systematic investigation of the anodization of both patterned and unpatterned specimens, phe-nomena of pronounced discrepancy with respect to pore size, pore density and pore etch-rate were evidenced. Based on the detailed analysis of scanning electron microscope （SEM） micrographs and current-voltage curves, the competition between physical and chemical elements was found to be cru- cial to understanding the observations. The results indicate that the size, density and growth-speed of pores may act as an evident function of the initial morphology of the sample surface, despite a nearly fixed width of the space charge region. Electric-field effect as well as current-burst-model （CBM） was employed to interpret the underlying mechanism.
