通过对煤-石墨系列样品的研究,发现了高煤级煤EPR演化的阶跃式特征,进而对其化学机理进行了探讨.研究表明:拼叠作用是高煤级煤中-后期阶段大分子基本结构单元发展的主要机理,其显著进展的起点位于镜质组最大反射率6.0%附近,大分子化学键的均裂则创造了拼叠作用得以实现的微地球化学环境条件
Through the research of coal-graphite series samples, the step-by-step characteristic of EPR evolution of high coal grade coal was discovered and its chemical mechanism was discussed. The research shows that the stacking effect is the high-rank coal-later stage macromolecule The main mechanism of the development of basic structural units, the significant progress of the starting point is located in the vitrinite maximum reflectance of 6.0% near the homogeneous cleavage of the macromolecules to create the role of spell stacking can be achieved micro-geochemical environmental conditions
