摘    要：三频组合波频率测深法是一种频率测深新方法,发送机同时发射3种频率的电磁波,接收机每一通道同时接收3种频率的电磁场分量,同时得到3种频率的波阻抗和2个相对相位差,且发射机和接收机之间不需相位参考系统,因而具有高效、高精度和接收设备轻便等特点.三频组合波的原理适合频域中的其它电法勘探,发射机具有多功能特性,接收机能设计成地球物理数据综合采集系统,故用途广泛。

Abstract: The major feature of the Triple-Frequency Electromagnetic frequency soundings(TFEFS)is that it transmits triple-frequency electromagnetic wave and measures triple-fre-quency field components simultaneously.For each channel of the receiver,three differentkinds of wave impedances and two different kinds of relative phase shifts are calculated atonce,By using relative phase shift measurements,this method does not require reference atthe transmitter and receiver.Therefore the TFEFS has the advantages of speedy measure-ments and high precision,According to the triple-frequency principle,the transmitter andreceiver are designed as a geophysical data acquisition system for other electric surveys aswell as the TFEFS survey.
