地面核磁共振技术发展述评

Review of development of surface nuclear magnetic resonance

核磁共振技术在医学、地质等方面都有广泛的应用.运用核磁共振技术找寻地下水资源,开创了用地球物理方法直接找水的先河.地面核磁共振技术是目前唯一能直接探测地下水的地球物理方法.本文通过对核磁共振技术在国内外的应用和发展现状的介绍,总结了地面核磁共振技术现在存在的问题及其影响,同时提出了该技术今后的发展前景.

Nuclear magnetic resonance （NMR） technique has been widely used in medicine and geology. While the use of NMR in ground water study is the fist time to lead the geophysical techniques in a new stage of detect ground water location. Surface Nuclear Magnetic Resonance （SNMR） is now recognized as the only geophysical method which can be used directly for groundwater study. In this paper, the applications and development of SNMR both in China and overseas are introduced, and some problems and limitations existed in them are analyzed. Finally some promising aspects of the technique in geophysical explorations are presented.
