【摘要】 首先讨论了频率域电磁测深中的记录规则，然后利用三维数值模拟结果作了具体分析。认为，在不考虑微弱的阴影效应时，将测深点作为频测记录点更为合理。野外试验对比说明了同样的结论。更多还原

【Abstract】 The present paper first discusses record rules in electromagnetic sounding of frequencydomain,and then makes a Specific analysis of simulation results with three-dimensional numericalvalues. The authors believe that,if the weall shading effect is not considered, it is moro reasonable to regard the sounding point as the frequency record point.This has been supported by fieldtest and comparison.更多还原
