摘　　要：为缩短羽绒残脂率的检测时间,首次尝试采用核磁共振法测定羽绒表面残脂率.即按索氏萃取法测定羽绒样品残脂率,考量核磁共振法工作曲线的有效性并以之测样品的残脂率.结果表明:与传统萃取法相比,用MQA7020核磁共振仪可准确快速测定白绒残脂率,测试时间从2个工作日缩短到几分钟,该方法高效、误差小、结果重现性好、无损伤、无毒无害,但灰羽绒里的铁磁性物质会极大影响测试结果.In order to reduce the testing time of fat and oil content of down, the paper aim to measure the fat and content （FOC） by using nuclear magnetic resonance （NMR） method for the first time. That is, Soxhlet extraction method is used for measuring the FOC of down samples, then the effectiveness of NMR work curve is examined. The results indicate that MQA7020 NMR analyzer is advantage to determine FOC of white clown quickly and accurately. The testing time is decreased from 2 days to a few minutes. This method has the advantages of high efficiency, small error, high reproducibility, no damage to sample, non-toxicity and harmlessness. But the ferromagnetic martial in down would influence the experiment results.
