| 摘 要： | 以猕猴桃鲜果为样品,在4.7T核磁共振成象仪上测量了质子密度象、扩散系数D的分布象、纵向弛豫时间T1分布象和横向弛豫时间TT2分布象,得到了鲜果不同部位的TT1、TT2和D的值,此外还进行了抑制水峰的定域波谱测量.所测得的定域波谱与猕猴桃果汁的1H高分辨核磁共振(NMR)谱进行了比较和归属.无损地获得了有关猕猴桃的形态结构和物质组成的一些信息.

| Abstract: | Four types of images of kiwifruit, i.e., proton density、diffusion coefficient D distribution、T1 distribution、T2 distribution magnetic resonance image, have been measured on a 4.7T mini imaging system. The T1、T2 and D values corresponding to different parts of kiwifruit were extracted. Three water suppressed 1H localized spectra were obtained and compared with a high resolution NMR spectrum of kiwifruit juice. The useful information about the morphological structure and material composition of the kiwifruit has been therefore noninvasively gotten. |
