摘　　要：低场核磁共振检测因其具有检测速度快、需样品量少且无损的特点,近年来受到了广泛关注,目前低场核磁共振检测尤其是脉冲技术的发展尚未形成体系。以低场核磁共振现有脉冲技术及NMR数据算法的发展为主线,介绍了低场核磁共振常用脉冲序列的结构和应用情况,以及NMR降噪、反演算法,并简要介绍了当前低场核磁检测在一些领域的应用情况。Low-field NMR detection has received extensive attention in recent years because of its fast detection speed,small sample volume and non-destructive characteristics.At present,the development of low-field NMR detection,especially pulse technology,has not yet formed a system.Focusing on the development of existing pulse technology and NMR data algorithms in low-field NMR,the structure and application of pulse sequences commonly used in low-field NMR,as well as NMR noise reduction and inversion algorithms are introduced,and the current low-field NMR is briefly introduced.It summarizes the check technology the application in some fields.
