摘　　要：利用梯度磁场实现检测信号的空间编码,是核磁共振成像(MRI)的关键技术.本文采用ccc系列样品将二维问题简化为一维,使用超小型教学用核磁共振成像仪进行了一维空间编码实验研究,并对实验过程及实验结果进行了计算模拟和分析.Spatial encoding using gradient magnetic fields is the key technique in nuclear magnetic resonance imaging(NMRI).With the miniature nuclear magnetic resonance imaging instrument,a series of NMRI one-dimensional spatial encoding experiments are performed as a try and exploration of advanced physics experiment teaching.We design the patterns and contents of the experiments,and carry out the computer simulation and analysis of the experimental results.

关 键 词：核磁共振成像 梯度磁场 空间编码
