摘要：

Surface Nuclear Magnetic Resonance (SNMR), a new geophysical method,can be used to detect groundwater directly,and which is currently the only way to find groundwater directly in the geophysical area.With the widely using of SNMR,the traditional model with loops as transceiver has been unable to meet certain specific requirements, while in the model of the finite grounding wire as the excitation source,we can receive SNMR signals in multi-channel, with high productivity, theoretically speaking,getting more accurate one-dimensional to three-dimensional information of underground aquifers. In this paper, we will calculate the magnetic field of finite grounding wires, and carry out numerical simulation for the underground aquifers SNMR responses excitated by line source obtaining that this method is feasible.
