摘要
本文利用Goldman-Shen脉冲序列测量了CaSO_4·(1/2)H_2O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。
~1H cross relaxation time between crystalline and adsorbed waters in
CaSO_4 1/2 H_2O 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 of
the ~1H spectrum line decays with three time constants. The present paper gives some explanations for the experimental results.
