这些结果表明，残炭颗粒的形态结构特征不仅依赖于煤的显微组分组成，而且也依赖于煤的变质程度。
The results indicate that the morphology and structure of char particles are dependent not only on maceral composition but also on coal rank.
结果显示，矿物质对煤粉的热解既有抑制作用，也有促进作用，取决于矿物质组成和显微组分组成。
The results show that the mineral matter either promotes or restrains the release of volatile, depending on the compounds of the mineral matter and macerals.
因为各显微组分组的性质不同，所以对大同煤的研究和利用必须考虑其煤岩组成的差别。
Because the properties of maceral groups are not similar, the difference of petrographic constituents should be taken into consideration when Datong coal is utilized or studied.
