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。
补充资料：偶极矩(dipilemoment)
【偶极矩】(dipilemoment)用以指示一个中性分子中电荷分配的常数。等于分子中正电中心与负电中心的距离`r`乘以正电荷或负电荷的电量`q`。它是矢量，方向沿着两电荷的连线，自负电荷指向正电荷。可用以衡量分子的极性，对于极性分子，分子的正负电荷中心不重合，偶极矩(`\mu`)大于零，而非极性分子中正负电荷中心是重合的，偶极矩为零。分子中原子核间的距离在`10^(-8)`厘米的数量级，分子的正电荷（或负电荷）的电量约在`4.8\times
