摘要

为了实现橡胶材料老化程度的无损快速现场测量,设计了一种便携式的单边核磁共振传感器。使用8个圆柱型磁体构成Halbach磁体结构,并采用8字形平面线圈作为射频线圈。使用该传感器对不同老化程度的橡胶样品进行了测量,结果表明:该系统能够准确测量橡胶样品的等效横向弛豫时间T_(2eff),根据等效横向弛豫时间的不同,能准确区分不同老化程度的橡胶材料。
        A portable NMR sensor for rapidly nondestructive measurement of the aging status of rubber material was presented.The NMR sensor consists of a magnet structure which is made up of eight cylindrical magnets and a figure'8'RF coil.Rubber material samples with different aging status were measured,the result demonstrates that: this sensor can accurately measure the equivalent transverse relaxation time T_(2eff) of the samples,and distinguish the aging degree of different samples based on their T_(2eff) values.
