摘要
本文通过介绍PCM的工作原理,以及分析检测过程中的注意事项和影响因素,并结合现场的埋地管道检验实例,对提高埋地管道的检测效率和检测精度总结出了一些有益的经验,并指出该技术在应用中尚存在一些局限性和不足之处。
By Introducing the working principle of PCM,the atteneions during the inspection and most factors which would influence this method were analyzed too. Connecting the inspection worksite examples on buried pipelines,it proposes some useful suggestion to improve the efficiency and accuracy of inspection. Meanwhile, it points out some limit and problems existed in this technique.
