【摘要】 根据近年来煤科学的主要进展以及煤的基本特征,对煤结构化学的概念、理论体系及其方法论进行了系统的论述.指出煤结构化学的理论体系根据其任务可分为实验煤结构化学和计算煤结构化学;根据煤的层次结构特征,煤结构化学可分为煤分子、煤超分子和煤聚集态结构化学.煤结构化学的方法论应从煤的基本特征出发,注重煤的多组成性以及它们之间的相互作用、煤的非晶态性、结构的层次性以及煤演化的阶段性,揭示煤结构特征与其物理化学性质关系的关键是建立先进的煤结构化学概念.更多还原

【Abstract】 Based on recent advances of coal science and the elementary characteristics of coal, the concept, theoretical system and methodology of coal structural chemistry were discussed.According to the purpose and task of coal structural chemistry, it can be divided into two parts, i.e.experimental coal structural chemistry, computing coal structural chemistry.According to the hiberarchy of coal, coal structural chemistry includes molecular structural chemistry of coal, supramolecular structural chemistry of coal and aggregate structural chemistry of coal.The methodology of coal structural chemistry must be built on the ground of the elementary features of coal, which include the composition of substances in coal and their interaction, the amorphous feature of coal, the hiberarchy of coal and the stage evolution of coal.The key to understand the relation of coal structure with the physical-chemical properties is to construct an advanced concept of coal structural chemistry.更多还原
