为研究小回线源瞬变电磁法的实际探测能力，进行了现场实验。实验数据显示，小回线源对浅部地层无法识别，但晚期信号较强，对实验地点的探测深度达到了100 m，对该处的地电特征有较好的反映。同时进行了数值模拟，模拟结果与实际探测结果基本一致。研究结果表明，合理选择发射与接收线圈的匝数，可以使多匝重叠小回线装置达到理想的探测深度。
為研究小迴線源瞬變電磁法的實際探測能力，進行瞭現場實驗。實驗數據顯示，小迴線源對淺部地層無法識彆，但晚期信號較彊，對實驗地點的探測深度達到瞭100 m，對該處的地電特徵有較好的反映。同時進行瞭數值模擬，模擬結果與實際探測結果基本一緻。研究結果錶明，閤理選擇髮射與接收線圈的匝數，可以使多匝重疊小迴線裝置達到理想的探測深度。

In order to study the reality exploration ability of the small multi-turn coincident loop ,repeat doing the field experiment. The experimental data shows that it′s difficult to identify the shallow stratum but the received late stage signal is strong, and the exploration depth reaches to 100 m and the device form has a good reflection on the character of the geoelectrical cross section. And do numerical simulation as well,the result agrees with the actual exploration result. The research results show that choosing the number of the transmitting and receiving loop,the small multi-turn coincident loop reasonably can reach to the anticipated exploration depth.
