简要介绍了二维双量子魔角旋转核磁共振(DQ-MAS NMR)新技术的基本原理,详细综述了1H,19F,29 Si,31 P和27 Al DQ-MAS NMR技术在各种固体功能材料中的应用,并展望了该技术的应用前景.

Solid-state NMR spectroscopy has been developed into a powerful tool for obtaining detailed information about the structure,ordering,and dynamics in various kinds of inorganic organic,and biological materials.Two-dimensional double quantum magic angle spinning（DQ-MAS） NMR experiment is a useful method for probing spatial proximities or interactions between nuclei in various solid materials.During the past decade,the DQ-MAS NMR technique has been successfully applied not only to spin I=1/2 nuclei,such as ^1H,^19F,^29Si,^31P,but also to quadrupolar nuclei system,such as ^27Al,^11B and ^23Na.In this paper,we briefly introduce the principle of two-dimensional DQ-MAS NMR,and review the recent applications of DQ-MAS NMR technique（including ^1H,^19F,^29Si,^31P and 27Al DQ-MAS NMR） to various solid functional materials.In addition,a perspective for the future of DQ-MAS NMR is also given.
