瞬变电磁法 transient electromagnetic methods / Transient electromagnetic methods

时间域电磁法 time domain electromagnetic methods 通过接受和分析用阶跃电脉冲激励在地下介质中产生的随时间变化的二次电磁场信号，识别目标地 层电性结构的探测方法。 注：瞬变电磁法的英文缩写为TEM；时间域电磁法的英文缩写为TDEM． 国标久久网 www.gb99.cn 免费下载 MT/T 1145-2011 2

Time domain electromagnetic methods A detection method that identifies the electrical structure of target strata by receiving and analyzing time-varying secondary electromagnetic field signals generated in underground media excited by step electrical pulses. Note: The English abbreviation for transient electromagnetic method is TEM; the English abbreviation for time domain electromagnetic method is TDEM.

多分量、多采集站 multi-components/multi-survey stations / multi-components/multi-survey stations

由多路信号通道的数据采集器组成采集站，利用多台分布式采集站的测点组合排列，能够以一台发 射机发射多台接收机接收的作业方式记录带有地层信息的电场和磁场随时间变化的响应数据。

The acquisition station is composed of data collectors with multi-channel signal paths. By utilizing the combination and arrangement of measurement points from multiple distributed acquisition stations, it can record response data of electric and magnetic fields varying with time, which carry formation information, through an operation mode where one transmitter emits and multiple receivers receive.

浅层探测、中深层探测、深层探测 the shallow depth probe/the mid-depth probe/ the large-depth / Shallow detection, medium-deep detection, deep detection

probe 目标地质体距观测系统布置的地表50m以内为浅层探测，50m～500m为中深层探测，大于500m为深层 探测。

Probe Target geological bodies within 50 m of the surface where the observation system is arranged are classified as shallow detection, those between 50 m and 500 m as medium-deep detection, and those greater than 500 m as deep detection.
