摘要/Abstract

摘要： 用核磁共振微成象中的自旋回波成象方法研究了γ辐射交联聚丙烯酰胺水凝胶体系,得到PAMG样品中交联网络的质子自旋密度分布之直观图象.对4个不同溶胀度的PAMG样品进行了实验测量,其实验结果清晰而直观地显示出样品中的交联网络随样品溶胀度的不同而变化的情况.

Abstract: The system of polyacrylamide hydrogel has been studied by means of Nuclear Magnetic Resonance Microscopy. There were four PAMG samples, which had been cross-linked by γ irradiation, with different degrees of swelling in D₂O. The proton spin-density distribution images of cross-linked networks in PAMG have been obtained.The experimental results have directly and clearly shown that the dimension of the cross-linked networks varies significantly with the degree of swelling of PAMG samples.

Key words: Polyacrylamide hydrogel, Magnetic resonance microscopy spin density imaging, Cross-linked network
