摘要
简述了流水式核磁共振的原理,利用自制的流水式核磁共振实验装置测量了纯水的纵向驰豫时间、强磁场(检测场)的强度、弱磁场(空间场)的三维分量的大小,对章动现象进行了观察和解释.
The principle of a NMR based on flowing water is introduced.Relaxation time,strong magnetic field and three elements of a weak magnetic field are measured by using the self-made NMR teaching apparatus of flowing water.The nutation effect is observed and explained.
