Abstract
The anisotropic diffusion of water in chive (Allium schoenoprasum) tissues has been investigated using two-dimensional nuclear magnetic resonance methods: diffusion-diffusion correlation spectroscopy and diffusion-relaxation correlation spectroscopy. Corresponding one-dimensional T2 and diffusion measurements confirm independently the results of the two-dimensional investigations. In particular the diffusion-diffusion correlation spectroscopy method proves to be very powerful in resolving the different components of the diffusion tensor at different sites in the sample.
摘要
利用二维核磁共振方法
扩散-扩散相关光谱法和扩散-弛豫相关光谱法，对细香葱（葱属植物）组织中水的各向异性扩散进行了研究。相应的一维T2和扩散测量独立地证实了二维研究的结果。特别是扩散-扩散相关光谱法在解析样品中不同位置扩散张量的不同分量方面被证明非常有效。
