| 摘 要： | 由于近区场的复杂性及目前频域电磁测深方法的局限性,近区频域电磁测深多年来一直是地球物理领域一个悬而未决的问题.本文在近区场理论的基础上,通过引人组合波理论,提出了一种能适于近区频域电磁测深的视电阻率的定义式.该视电阻率在近区具有有效压制背景场、突出地电异常信息的功能,并能客观地反映地电断面的电性变化规律.

| Abstract: | Due to the complexity of the near-region field and the limitation of the frequency domain electromagnetic sounding used at present, the near-region frequency domain electromagnetic sounding remains an unsolved problem in geophysics. Based on the theory of near-region field, the present paper, by introducing the theory of combination wave, has put forward a definition formula of apparent resistivity suitable for near-region frequency domain electromagnetic Bounding. Such an apparent resistivity can effectively suppress background field in the near region, make prominent the function of geoelectric anomaly information, and reflect objectively electric variation regularity of geoelectic section. |
