摘　　要：通过分析皮尔逊检测法、交流电流梯度法、直流电位梯度法和密间隔极化电位法等几种埋地环境下管道外腐蚀检测技术的工作原理及技术特点,研究了这几种方法用于埋地环境下容器外腐蚀检测的可行性。同时,提出了电阻探针法、电感探针法、场信号法、耦合多电极腐蚀监测等几种外腐蚀在线检测技术,为开展相关工作提供了理论参考。By analyzing the working principle and technical feature of the detection technology for the external corrosion of buried pipeline,including pearson,pipe current mapping,direct current voltage gradient and close interval potential survey,the feasibility of the external corrosion detection of buried vessel by these methods was analyzed.Meanwhile,several on-line external corrosion monitoring technologies of soil corrosion were introduced,such as electrical resistance probe method,inductance probe method,field signal method,coupling electrode corrosion monitoring,etc.which offered theory reference for doing correlative work.
