摘要: 煤的大分子结构可用化学方法和物理方法进行研究。在化学方法中,煤结构统计分析法占有重要地位,但其结果存在一定统计误差。本文研究了一系列不同级别煤的高角X射线散射强度,结果表明,随煤级别增高,煤大分子结构的X射线参数的变化是连续的。显然,这一工作对于研究煤中大分子的结构是很有意义的。

Abstract: The high-angle scattering intensities from coals can be interpreted with a modle of a buckled sheet of a macromolecule in coal. Those which take part in the (hk) 2-dimensional interferred scattering, i. e. aromatic lamellae, only make up of a part of a macromolecule in coal. Amacromolecule in coal consists of a few aromatic layers through the cross-linking bonds of amorphous materials, such as, aliphatic materials, hydro-aromatic groups, five-ring structure etc.. With the increase of the rank of coals, the dimension of aromatic layers increases, and amorphous materials decrease.

Key words: Coal, Coal structure, Macromolecule in coal, X-ray scattering
