摘　　要：研究阳极氧化铝模板的孔间距与电解液、温度和氧化电压等影响因素的关系现状。指出孔间距受电解液种类和氧化电压的影响最大,而电解液浓度和温度的影响甚微,模板的孔间距随电压的增加而增加。通过调整电解液和氧化电压可制备所需孔间距的模板。制备大孔间距模板可采用磷酸作电解液配以较大的氧化电压。制备孔间距<10nm的模板可采用H2SO4作电解液配以较小的氧化电压,但当电压很低时阳极氧化反应可能无法进行,可以用较高的脉冲电压代替;也可先采用H2SO4和Al2(SO4)3混合液作电解液辅以较小电压或脉冲电压进行氧化。The relationship between the interpore of anodic aluminum oxide （AAO） template and the influencing factors of electrolyte, temperature and oxidation voltage etc. was researched and summarized in this paper. It was pointed out that the interpore was influenced mostly by electrolyte type and oxidation voltage, and least by the electrolyte concentration and oxidation temperature. The interpore of AAO template increases with the oxi- dation voltage increases. By adjusting the electrolyte and oxidation voltage, a desired interpore of template can be acquired. To acquire a large interpore template, electrolyte of phosphoric acid under a comparatively higher oxidation voltage can be used. To acquire template with interpore less than 10nm, sulfate electrolyte under a comparatively lower oxidation voltage can be used, but the oxidation reaction can＇t work with small voltage, with the help of higher pulse voltage the problem will be solved. Alternatively, oxidizing with a mixed electro- lyte of H2SO~ and A12 （SO4）3 and small voltage or higher pulse voltage.
