摘　　要：通过扫描电镜观测了不同的硫酸含量对低压铝箔腐蚀形貌的影响,结合比容和称重检测手段,解释了产生局部的不腐蚀形貌和大孔洞形貌可能的原因。综合比容值和机械强度的考虑,得到了硫酸含量的最优条件。The effect of H2SO4 with different concentrations on the corrosion morphology has been discussed by means of SEM,capacitance and foil weight measurement.The possible reason has been explained why parts of the aluminum foil weren’t etched with some bigger holes appearing in SEM eyeshot.Considering capacitance and mechanical strength,the optimal H2SO4 concentration has been found.
