摘要
采用热分析技术对２种渣油、４种沥青、３种吸氧老化沥青和经吸附柱色谱法分离得到的４种沥青组份的热性能进行了研究，获得厂各种试样的热重（ＴＧ）、微分热重（ＤＴＧ）和差热（ＤＴＡ）曲线，从热性能方面揭示了这些试样的差别、并对试样的族组成进行了探讨。
the thermoproperties of two residual oils,four petroleum asphalts,three petroleum asphaltsaged on oxygen absorption and four petroleum asphalt constituents were studied by thermoanalysis.The TG,DTG and DTA curves of the test samples were obtained from which the differencesamong these samples can be clearly discerned.The group compositions were also studied.
