摘　　要：利用实验室测试和现场测试相结合的方法对比研究了国内外四种交流排流器的服役性能。通过实验室直流伏安特性测试和交流伏安特性测试,分别获得了四种交流排流器的直流阀值电压、直流漏流量以及交流阻抗,并利用现场测试对该结果进行了验证。通过现场测试获得了四种交流排流器对管道阴极保护电位和阳极地床交流缓解效果的影响规律和作用机制。The performances of four direct current （DC） decouplers were investigated by the combination of experimental measurements and field tests. In order to evaluate the IX; threshold voltage, DC leakage and alternating current （AC） impedance, DC volt-ampere curve and AC volt-ampere curve of the four DC decouplers were measured. The results were confirmed by field tests. Besides, the effects of DC decoupler on the AC mitigation efficiency of ground-bed and on the cathodic protection potential of buried pipeline were discussed.
