| 摘 要： | 核磁共振（NMR）实验是近代物理实验的一个重要环节。文章分析了核磁共振实验中由于样品位置不重合对实验结果的影响。实验发现当1H样品和19F样品位置不重合时实验误差基本可以忽略。由此可知外场线圈产生的磁场在中心区域基本上是均匀的。

| Abstract: | Nuclear Magnetic Resonance （NMR） is an important experiment in modern physics education. The effect of distance of two different samples （1H, 19F） on the experimental results has been investigated in this paper. It is found that weather the samples is overlap or discrete has negligible effect on the experimental results. The magnetic field is in the center of the set - up. |
