摘要
运用分子轨道理论并引入能带理论，从分子统计学角度，提出了显微组分的荧光机理。指出分子游离相内生荧团与生荧团之间的能量转换效率，及生荧团与大分子网络相之问能量传递效率决定了显微组分的荧光性质；显微组分荧光变异机理则受３个因素的制约，即温度效应、光氧化效应及“游离”效应。进而从显微组分荧光机理出发，对吐哈盆地煤成烃显微组分生油模式进行了分析，提出基质镜质体、木栓质体和角质体是吐哈盆地煤成烃主要贡献组分。
By means of the molecular orbital theory and molecular energy band theory, the mechanism of maceral fluorescence is proposed. Based on our analysis, the maceral fluorescence emission depends both on the efficiency of transfer energy among fluorophores in mobile phase, and on the transmit efficiency between fluorophore existing in mobile and macromolecular network phases. The mechanism of maceral fluorescence alteration is decided by three factors: 'temperature effect', 'photo-oxidation effect' and 'drift effect'' On the basis of maceral fluorescence mechanism, the model of maceral's oil-generating for coal--derived hydrocarbon in Turpan-Hami basin is analyzed, suggesting that the main contributors for coal-derived hydrocarbons in Turpan-Hami basin are desmocollinite, suberinite and cutiriite.
