用１Ｈ／１３Ｃｎ．ｍ．ｒ．联合解析的方法分析表征了澄清油中间相沥青和乙烯渣油中间相沥青甲苯可溶组分（ＴＳ）和甲苯不溶吡啶可溶组分（ＴＩ－ＰＳ）的平均结构特征，并给出了满足平均结构参数的平均结构模型。为研究中间相沥青的形成机理以及调制合适的纺制高性能炭纤维的原料－中间相沥青提供了结构信息
With 1H / 13Cn. m. r The average structural characteristics of the toluene soluble fraction (TS) and the toluene insoluble pyridine soluble fraction (TI-PS) of the clear oil mesophase pitch and the ethylene residue mesophase pitch were characterized and analyzed by the joint analytical method. Average Structural Model of Average Structural Parameters. Structural information was provided for the study of the formation mechanism of mesophase pitch and for the preparation of mesophase pitch, a suitable raw material for spinning high-performance carbon fibers
