核磁共振脉冲梯度自旋回波（PGSE）自扩散技术应用于具有渗透屏障的系统。该体系是一种由97%水组成的高浓缩乳液，其内部结构是由薄油膜隔开的紧密堆积的水滴。这些油膜是可渗透水的，因此乳液可以被认为属于一般类型的多孔系统。最近，Callaghan 及其同事通过理论和实验证明，在某些条件下，当 PGSE 实验应用于多孔系统时，人们实际上可以检测到类似衍射的效应
The NMR pulsed gradient spin echo (PGSE) self-diffusion technique is applied to a system with permeable barriers. The system is a highly concentrated emulsion consisting of 97% water, and its internal structure is one of closely packed water droplets which are separated by thin oil films. These oil films are permeable to water, and the emulsion can therefore be considered as belonging to the general class of porous systems. Recently, Callaghan and co-workers showed both theoretically and experimentally that under certain conditions one may actually detect diffraction-like effects when the PGSE experiment is applied to porous systems
