| 摘 要： | 本文指出了在核磁共振实验中通常使用的通过测量信号宽度求横向弛豫时间的方法的局限性。介绍了以特殊的射频脉冲序列来测量横向弛豫时间的“自旋——回波”方法和测量纵向弛象时间的“倒置——恢复”方法。

| Abstract: | In this paper ,the limitation of the method which was usually used to determine the T3 by measuring the signal width is pointed out. The special RF pulse sequences are introduced to measure T2 by"Spm -Echo".and T1 by "Invert- Recover". |
