| 摘 要： | 本文将固体核磁中的交叉极化与魔角旋转(CP/MS)技术与Goldman-Shen脉冲序列相结合,研究了不同分子量的单分散聚苯乙烯/聚异戊二烯嵌段共聚物(SAI)中磁化矢量的自旋扩散速度。以一个均匀分布的相结构模型为基础,求解了扩散方程和样品中的微区尺寸。

| Abstract: | Goldman-Shen pulse combined with CP/MAS techniques were applied to investigatethe spin diffusion process of polystyrene/polyisoprene copolymers. Based on a uniformly distr-ibuted domain model and appropriate boundary and initial conditions, the diffusion equation wassolved and the domain size of the samples were obtained there from. |
