摘　　要：核磁共振已成为分子科学、材料科学和生命科学等领域研究物质结构、动态过程及物理特性最有效的工具之一.本文将基于Bloch方程研究核磁共振现象及相关实验参数如共振频率和弛豫时间,同时对实验中常用的脉冲序列如Single Pulse,Inversion Recovery,Spin Echo,CPMG等进行系统模拟,揭示出不同脉冲序列的物理意义.The nuclear magnetic resonance(NMR)has become one of the most effective tools to study the structure,dynamic processes and physical properties of molecular science,material science,life science and some other fields.We focus on the study of nuclear magnetic resonance according to the Bloch Equation and the related experimental parameters,such as resonance frequency and relaxation time.Meanwhile,the pulse sequences including Single Pulse,Inversion Recovery,Spin Echo,CPMG and etc are simulate.Thus we reveal consequently the physical origins of different pulse sequences.
