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。
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。
