摘　　要：对于一定空间区域内设计的物理模型,在阳极开路电位为-1.050V（vs.SCE）、海水电阻率为0.25Ωm,阴极自腐蚀电位为-0.650V的条件下,针对同样体积但尺寸不同的圆柱形牺牲阳极、方条形牺牲阳极和长直 翼型牺牲阳极考察阳极极化电阻对阴极保护效果的影响,以及阴极保护时-空变化的影响.A physical model is prepared within a certain spatial region. In the anode, the open circuit potential is -1.050V （vs. SCE）, while resistivity of seawater is 0.25Ω m, and corrosion potential is -0.650V. Effect of resistance of anode polarization on cathodic protection and effect of space region on temporal and spatial variation are studied for the same volume but different sizes of cylindrical anodes, square strip anodes and long straight airfoil sacrificial anodes..
