摘要/Abstract

摘要： 流体流动的核磁共振（NMR）在线测量是一种高效、无损的探测方式，可广泛应用于管道流体输送过程、化学反应动态流程、河流流动等具有时移变化特点的过程在线检测.但是流动状态下样品流速会对NMR测量造成诸如磁化时间不充分、采集信号损失等不容忽视的影响.通过量化分析流动状态对NMR测量的影响因素，提出回波串校正方法，实现流动状态下的NMR流体测量.

关键词: 校正, 低场磁共振(low-field NMR), 在线测量, 流速影响

Abstract: NMR measurement of flowing fluid is a highly effective and non-destructive online detection method, which can be widely used in pipeline fluid delivery process, chemical reaction process, river flowing process and other time-shift processes. However, flow will induce incomplete polarization and incomplete signal acquisition, such that the effects of flow rate on NMR measurement cannot be ignored. In this work, we analyzed quantitatively how factors related to the flowing state affect NMR measurement. Correction methods were proposed to achieve accurate NMR flowing fluid measurements.

Key words: low-field NMR, online measurement, flowing effects, correction
