针对定源回线装置瞬变电磁法观测三个分量瞬变响应的特点，利用三维正演模拟计算了均匀半空间以及不同产状低阻薄板的三分量响应，并对瞬变响应曲线特征进行了初步分析。计算结果表明，水平分量响应能够显示异常体的边界、位置，垂直分量响应主要反映异常中心。多分量综合解释可以更准确地反映地下异常体的中心位置、边界范围等几何参数，为实际资料解释提供依据。

The fixed-loop TEM method can measure three components of TEM response.This paper gives the three-component response of union half space and thick plate models with three dimensional forward modeling soft ware and the char-acteristic of TEM curves are summarized.The calculation results show that horizontal component can show the edge and posi-tion of anomy body,while vertical component is sensitive to the center part.Multi-component survey can offer more reliable information and give more proof for interpretation of field data.
