摘　　要：运用扫描电镜能谱微区测试对不同沉积环境成因煤的有机显微组分进行有机硫含量的系统测定，结果表明在不同类型的煤中某一类显微组分的有机硫含量存在明显差异；同一煤中不同亚显微组分的有机硫含量也不同。综合分析发现煤显微组分有机硫含量主要受聚煤环境、组分凝胶化程度、氧化程度的影响，而聚煤环境为主导影响因素。Determination of organosulfur content for macerals in coals accumulated in different environments have been conducted useing microprobe of scanning electronic microscopy.The results shows thatthere exists distict discrepancy in organosulfur content for centain maceral from different kinds of coals,whilethe organosulfur contents for macerals in the same coal are also in difference.We have found out thatorganosulfur content of coal maceral was determinded by sedimental environment and the extents of gelification and oxidation of maceral,amoung which sedimental environment was the main factor.
