摘要：
Overhauser imaging in a magnetic field of 16 mT was employed for a study of water transport during the drying process of an agar gel. The data illustrate important aspects of Overhauser imaging, such as the large sensitivity to small changes of local moisture, which may be attainable under appropriate conditions. The non-Fickian nature of the water transport process can be clearly inferred from the measured moisture profiles.
