As in other electromagnetic sounding methods,static offset and correction also arise in frequency-domain electromagnetic sounding. 在電磁法勘探中，頻率域電磁測深法也存在靜態(tài)偏移與校正問(wèn)題。
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，瞬變電磁法，頻率域電磁法，直流電法和地震法等。
