通过分别浸泡在氘代吡啶和氘代丙酮溶剂中的煤的核磁共振成象,观察了溶剂在煤中的渗透、扩散过程和溶胀作用。并得到了煤的大分子网络中的动态小分子的分布情况。由核磁共振成象技术获得了煤的化学和物理结构信息。
The permeation, diffusion and swelling of the solvent in the coal were observed by nuclear magnetic resonance images of the coal immersed in deuterated pyridine and deuterated acetone respectively. The distribution of small dynamic molecules in coal macromolecule network was obtained. The chemical and physical structural information of coal was obtained by NMR imaging.
