分别测量了在阻挡型和多孔型电解质溶液中，铝阳极的恒电压和恒电流极化曲线．根据铝阳极极化曲线的特点，讨论铝在阳极氧化过程中有关阻挡层的形成、部分溶解，以及转化为多孔层等过程与极化电压和电流的关系．提出了在低极化电压或电流下，孔胚按“慢少成孔”机理在高极化电压或电流下按“快多成孔”机理的观点． The polarization curves of constant voltage and constant current of aluminum anodes were measured respectively in the barrier type and porous electrolyte solutions. According to the characteristics of the anodic polarization curves of aluminum, the relationship between the formation of aluminum in the anodic oxidation process, partial dissolution, and the conversion into porous layer and the polarization voltage and current were discussed. Proposed under the low polarization voltage or current, the hole embryo according to the “slow hole into the hole” mechanism under high polarization voltage or current according to the “quick multi-hole” mechanism point of view.
