地電流法探査の英語

この地下電磁探査方法では、送信ループへの通電を遮断し地山に渦電流が伝播するスモークリング現象を発生させ、前記渦電流の減衰を受信ループを用い電磁場の時間関数の変化として測定する電磁探査を、地表面側の複数の測定ポイントに沿って繰り返し行なう（Ｓ１〜Ｓ４）。例文帳に追加

In this underground electromagnetic surveillance method, electromagnetic surveillance of cutting off energization to a transmission loop, producing a smoke ring phenomenon in which an eddy current propagates to the bedrock, and measuring attenuation of the eddy current as a change of a time function of an electromagnetic field using a receiving loop is repeatedly performed along a plurality of measurement points in a ground surface side (S1-S4). - 特許庁
