摘　　要：本文利用喷气燃料主要组分之一的正十二烷,讨论了通过TA Q2000差示扫描量热仪(PDSC法)在静态氛围中考察喷气燃料热氧化安定性的可行性,并得出了PDSC法测定正十二烷氧化诱导期和氧化起始温度的最佳实验条件,通过阿伦尼乌斯方程求得了正十二烷的氧化活化能为122. 82 kJ/mol。In this paper,the feasibility of investigating the thermal oxidation stability of jet fuel by high pressure differential scanning calorimeter( PDSC) is discussed by using the one of the main components of the jet fuel. The best experimental conditions for the determination of the oxidation induction period and the starting temperature of the positive twelve alkane oxidation are obtained by the method of Arrhenius. The oxidation activation energy of the twelve alkane is 122. 82 k J/mol.
