The techniques adopted include magnetic method, gravity, transient electromagnetic method, frequency domain electromagnetic method, direct current method and seismic method. 其中包括磁法,重力,瞬变电磁法,频率域电磁法,直流电法和地震法等。
As in other electromagnetic sounding methods,static offset and correction also arise in frequency-domain electromagnetic sounding. 在电磁法勘探中,频率域电磁测深法也存在静态偏移与校正问题。
