The relationship between capacitance and corrosion conditions in the enlargement of tunnels justifies the latter competition mechanism the varied etching conditions were implemented by enhancing the passivating characteristics and viscosity , changing the a13 + concentration , temperature of etchants and current pulsation . passivating acid in the etchant is conducive to the instant passivation of exposed areas on the foil surface , and hence sustains the balance of competition between aggressive anions and passivators , providing pit nucleatiori sites continuously
通过侵蚀液中添加草酸、硫酸、乙二醇，改变侵蚀液al ~ ( 3 + )浓度和电流纹波等方法，研究了不同的侵蚀条件对隧道孔形貌和比容的影响，结果表明：草酸和硫酸既保护了铝箔表面又促进了隧道孔孔壁的迅速钝化，增加发孔密度。
