综述了埋地管道交流腐蚀的研究现状，包括人们对交流腐蚀的认识过程，交流腐蚀的特征和机理，交流腐蚀风险的评价方法以及交流腐蚀的缓解措施。最后提出了埋地管道交流腐蚀有待解决的问题。

Alternating current (AC) corrosion on buried pipelines has drawn much attention. Current status of the researches is reviewed in this article. The understanding of AC corrosion is mentioned. Characteristics, mechanisms, and mitigations of AC corrosion and the evaluation methods for AC corrosion risk are concluded. Finally, the issues for further investigations are proposed.
