Based on an analysis of the formation mechanism of induced current in underground pipelines, theauthor holds that, where underground media show very poor conductance, underground pipelines are dominated bymagnetic dipole lines, and where underground media have certain conductance, pipelines are equivalent to electricwires.
通过对地下管线中的感应电流形成机理分析，本文认为，当地下介质导电性很差时，地下管线以磁偶极线为主；而当地下介质存在一定的导电性时，管线则等效于电流线。

由于探地雷达偶极天线具有电磁极化特性,其发射天线主要发射沿着天线长轴方向的线性极化波,而接收天线对这种极化方向的电磁波也最灵敏。

“质子-电子偶极-偶极”质子弛豫增强
物理学术语。原子核外层中不成对的电子质量小，但磁动性很强，可使局部磁场波动增强，促使氢质子弛豫加快，从而使T1和T2缩短，这种效应即为PEDDPRE。过渡元素和镧系元素大部分在d和f轨道有多个不成对电子，所以其离子往往具有PEDDPRE，可用来作顺磁性对比剂，如钆(Gd)。Gd在外层有7个不成对电子，具有很强的顺磁性。
