^1H NMR imaging patterns with information about the spatial distribution of ^1H spin density and ^1H spin-spin relaxation time T_2 of water molecules in a crosslinked polymer gel were successfully measured, in order to clarify the translational behavior of water molecules in the gel under the propagation of stress-strain and shrinkage process by the application of an electric field. From these experimental results it was found that the propagation mechanism of stress-strain and the shrinkage process were elucidated.

为了阐明交联聚合物凝胶中水分子在电场作用下应力-应变传播和收缩过程中的平移行为，成功地测量了交联聚合物凝胶中水分子的^1H自旋密度和^1H自旋-自旋弛豫时间T2的空间分布信息.从这些实验结果中，它被发现的应力-应变的传播机制和收缩过程阐明。
