摘要
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。
Decant oil mesophase pitch and ethylene tar residue mesophase pitch were separated by sequential solvent extraction into toluene soluble (TS) and toluene insoluble but pyridine soluble(TIPS) fractions. Average molecular parameters (AMPS) for each fractions were obtained by combined analyses of 1 H n.m.r.and 13 C n.m.r.spectrometry. Average molecular structures which correlated with the observed data were drawn .The structural information may give some indication of the derived mesophase texture,which governing the production performance and properties of resultant carbon fibres.
