| 摘 要： | 本文利用Goldman-Shen脉冲序列测量了CaSO4·(1/2) H2O样品中结晶水与吸附水1H的交叉弛豫时间为55.1ms。在实验中,发现剩余窄线的磁化矢量随时间的衰减有三个过程。本文对此现象作了一些分析讨论。

| Abstract: | 1H cross relaxation time between crystalline and adsorbed waters inCaSO4 1/2 H2O powder was found to be 55.1 ms by use of the Goldman-Shen pulse sequence. In experiment, it was discovered that the narrow component ofthe 1H spectrum line decays with three time constants. The present paper gives some explanations for the experimental results. |
