摘要/Abstract

摘要：

磁共振成像（MRI）是一种高效无损的检测手段，近年来在工程领域得到了一定的应用. 采用MRI技术对常压下四氢呋喃（THF）水合物在水溶液和玻璃砂2种体系中的生成过程以及饱和度变化进行了检测. 结果表明：MRI是一种对水合物生成过程检测的有效方法；通过阈值分割方法将MRI灰度图像转化为二值图像后可以通过二值图像的积分值对THF水合物的饱和度进行分析.

关键词: 磁共振成像(MRI), 饱和度检测在, 阈值分割法, 二值图像积分, 四氢呋喃水合物

Abstract:

MRI is an effective and non-invasive method which has been applied to engineering field in recent years. In this study, MRI was used to monitor tetrahydrofuran (THF) hydrate formation under ambient pressure and its saturation in bulk solution and in glass beads pack. It was shown that MRI is an effective method for monitoring hydrate formation. To measure saturation of hydrate formed in bulk and glass beads, grayscale images obtained were firstly converted to binary images, which were then analyzed by the threshold segmentation method.

Key words: MRI, saturation, threshold segmentation, tetrahydrofuran hydrate
