The general development of Rheo-NMR during the last four decades as well as selective hyphenated apparatuses is presented. Based on different magnet types, the current review is divided into two categories, namely low-field and high-field NMR, while the time-domain NMR is normally applied in the former case and the frequency-domain NMR is adopted in the latter one. Depending on different rheometer cells, it can be further divided into tensile and shear mode Rheo-NMR. The combination of various rheometer cells and NMR facility guarantees our acquisition of molecular level structure and dynamics information under flow conditions, which is crucial for our understanding of the molecular origin of complex fluids. A personal perspective is also presented at last to highlight possible development in this direction.
本文介绍了流变核磁共振（Rheo-NMR）在过去四十年中的总体发展情况以及选择性联用仪器。基于不同的磁体类型，当前的综述分为两类，即低场和高场核磁共振，其中时域核磁共振通常应用于前一种情况，而频域核磁共振则应用于后一种情况。根据不同的流变仪样品池，它可以进一步分为拉伸和剪切模式的流变核磁共振。各种流变仪样品池与核磁共振设备的结合，确保我们能够在流动条件下获取分子水平的结构和动力学信息，这对于我们理解复杂流体的分子起源至关重要。最后还给出了个人观点，以突出这一方向可能的发展。
