分别测定了PAC电极（Pb－Ag－Ca新型阳极的简称）在MnSO4－H2SO4溶液中的阴极极化曲线（以～lgi作图）及阳极极化曲线，从图中求得：icor＝15．85μA／cm2，cor＝－0095v，Vcor＝2．95Kg／m2ann．7．09％（电极重量每年消耗的百分数）io（2）=54．70μA/cm2及io（3）=1．10μA／cm2；讨论了PAC阳极的腐蚀机理即反应（2）受反应（3）的动力学参数所控制，为EMD工业中使用该阳极提供基础性数据．
The cathodic polarization curve (plotted as ~ lgi) and the anodic polarization curve of the PAC electrode (short for Pb-Ag-Ca new anode) in MnSO4-H2SO4 solution were determined. 85μA / cm2, cor = -0095v, Vcor = 2.95Kg / m2ann. 7.09% (the percentage of electrodes consumed per year) io (2) = 54.70μA / cm2 and io (3) = 1.10μA / cm2. The corrosion mechanism of PAC anode was discussed. ) Kinetic parameters, providing the foundational data for the use of the anode in the EMD industry.
