【 摘 要 】

Proton nuclear magnetic resonance is a type of nuclear magnetic resonance (NMR), which is widely used to detect hydrogen containing liquids, like water or hydrocarbons. The use of the Earth's magnetic field allows remote detection of fluids sub surface without generating an independent magnetic field that is expensive and complex enough to apply. An important feature of NMR in the Earth's field is that the signals produced by snow and ice are generally unobservable under experimental conditions created for liquid water prospecting. The characteristics of the RF response are associated with the molecular environment of the nuclei. This allows detecting NMR signals of water in pores of various size.
