EM exploring methods are less disturbed by ground conditions, and can be carried out continuously and efficiently. 电磁法探测地下水受地面条件影响较小，可以连续测量，成本低廉。
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。
