摘　　要：目前高校开设的核磁共振实验虽然操作简单、测量计算容易,但学生对核磁共振现象与原理的理解不深.针对这种现状,阐述了拓宽相关实验内容的必要性,并就"横向弛豫时间的估算"、"横向弛豫时间与溶液浓度的关系"等拓展内容进行了研究与探讨.At present,the NMR experiment founded in colleges has the feature of simple operation and easy measuring, so that students have little study on the NMR phenomenon and principle. In the view of these situations, this article elaborates the necessity of expanding the content of related experiment, and then studies and discusses the expending contents on ＂estimate of relaxation time＂, ＂the relations of relaxation time and the concentration of solution＂ and so on.

关 键 词：核磁共振 弛豫时间 共振频率
