摘　　要：系统地综述了交流干扰对阴保电位、阴保电流密度、牺牲阳极电位、牺牲阳极消耗速率、牺牲阳极效率等参数的影响,同时阐述了交流干扰下阴保评价准则及交流腐蚀机理的最新研究成果。最后指出了目前研究存在的主要问题,展望了该研究领域的发展趋势。The dramatic development of oil, electric power and transportation industries deteriorated alternating current （AC） interference of the pipelines. As a consequence, not only the corrosion of pipelines would be enhanced, but also the cathodic protection （CP） systems be affected significantly. The traditional CP criterion （-850 mV（vs CSE）） was ineffective and a new CP criterion was in needed. The researches about effects of AC interference on CP parameters, such as CP potential, CP current density, sacrificial anode potential, sacrificial anode consumption rate and sacrificial anode efficiency, were reviewed in this article. At the same time, the latest researches on CP criterions and AC corrosion mechanisms were introduced. Finally, the key problems were indicated and the development trend of this research field was predicted.
