摘要
通过系统测试，查明了镜质体油浸最大反射率在２．０％～１０．０％之间的样品中粒粒体反射率的演化轨迹，发现其最大反射率的演化具有“转折”特征。粗粒体化学结构的“非石墨化碳”性质、物理结构的“富微孔性”及构造应力的作用是控制反射率演化的主要因素。
ased on the results of the systematical measurements, the evolved chracteristics of the macrinite reflectance of the high-rank coals,with 2. 0%- 10. 0% of vitrinite reflectance,was ascertained and the inversion of the coalification path was revealed. Further,the mechanism on the evolution was inquired into and it was considered that the chemical structure with non-graphitizing carbon,the physical structure with developed micropores and strong tectonic stress occured during the coalification were resposible for thecharacteristics.
