The sacrificial anode cathodicprotection features no power source, simple management and even current distribution. It is well received especially on special shaped structure.
牺牲阳极法阴极保护因其不需电源、管理简单、电流分布均匀，特别是对于形状特殊的构筑物。
2
Normally cathodicprotection is acquired by sacrificial anodes or impressed current.
阴极保护常采用牺牲阳极法和外加电流法。
