摘　　要：传统NMR技术需将被检测物体置于高频超导磁铁中心,其应用范围受到了很大限制。近年来出现了一种新型便携式核磁共振通用表面探测仪(NMR-MOUSE),它可以放置于被检测物表面进行在线分析,灵敏地检测出材料的变化,可在相关领域用于评估材料性能,并预测材料的使用寿命。文中主要介绍NMR-MOUSE的基本原理,并着重讨论其在非均相橡胶和塑料高分子聚合物表征领域中的应用情况。In the traditional Nuclear Magnetic Resonance （NMR）, the tested substance should be located on the center of homogeneous magnetic field of superconductive magnet, which limited the application of NMR to some extents. Recently a novel NMR spectrometer, the NMR-MOUSE （nuclear magnetic resonance mobile universal surface explorer）, was developed and characterized by small volume, convenient transferring and surface analysis, which can be used to on-line analysis on the surface of tested substances and is sensitive to material changes, thus allowing non-destructive assessment and the life time predications of materials. The fundamental principle of this novel NMR-MOUSE was introduced in this paper, with its application in characterizing of heterogeneous rubber and plastic polymers discussed.
