英文摘要	二维核磁共振(2dnMr)的提出和发展,为nMr技术的研究和应用提供了广阔的空间.然而当样品或磁场本身不均匀时,高分辨的2dnMr谱难以获得.此外,常规2dnMr实验通常需要长的采样时间.空间编码超快速采样方法利用空间编码技术,只需单次扫描即可获得2d甚至多维nMr谱,极大地缩短了采样时间.目前相位补偿、相干转移和分子间多量子相干等技术与空间编码技术相结合,已成功实现不均匀场下超快速获得高分辨nMr谱.该文对不均匀场下空间编码超快速nMr方法进行了介绍,对其未来发展进行了展望.; The proposal and development of two-dimensional nuclear magnetic resonance(2DNMR)provide a broad space for the research and application of NMR.In many cases,however,high-resolution 2Dspectra are virtually impossible to obtain because of the inherent heterogeneity of the samples under investigation,as well as the poor homogeneity of the magnetic fields.It is also time-consuming to obtain a conventional 2D NMR spectrum.The ultrafast spatial encoding technique enables acquisition of a 2Dor multi-dimensional NMR spectrum within a single-scan,with greatly shortened acquisition time.Schemes based on phase compensation,coherence transfer and intermolecular multiple-quantum coherence in combination with spatial encoding technique have been proposed to ultrafast obtain high-resolution NMR spectra in inhomogeneous fields.In this review,ultrafast high-resolution NMR techniques were introduced and the perspective of these techniques was discussed.; 国家自然科学基金资助项目(11275161;11074209)
