| Abstract: | The paper mainly elaborates the principle and characteristics of directly detecting underground water with the Surface Nuclear Magnetic Resonance(SNMR)method,the apparatus,and the control of surveying quantity.On the basis of the pracice of exploring groundwater in granite regions,the feasibility of the method and its advantage are illuminated in this article.The factors of effecting NMR signal connection and NMR signal interpretation results are summarized. A few proposals and future research directions are also put forward. |
