　　In electrolyte of pure ZnSO4-H2SO4, the anodic oxygen evolution potential,corrosion rate and structure of anodic oxide layers of traditional flat Pb-Ag (0.8%) anode were studied in long time polarization under different current densities.Additionally, the current efficiency and quality of Zn were studied in the electrolyte of ZnSO4-MnSO4-H2sO4.The composition of the anodic oxide layers was characterized by XRD and SEM analysis.
