用差示扫描量热仪（ＤＳＣ）技术研究了某些含能材料及相关物的低温焓松弛过程及时温等效，通过玻璃化转变温度与升温速率的关系，导出了ＷＬＦ方程粘弹系数的计算式，并计算了１０个体系的粘弹系数，实验结果表明，用ＤＳＣ技术可以测定焓松驰和ＷＬＦ方程的系数。
Using the differential scanning calorimeter (DSC) technique, the low-temperature enthalpy relaxation process and the time-temperature equivalent of some energetic materials and related materials were studied. The relationship between the glass transition temperature and the heating rate was derived and the viscoelastic coefficient of the WLF equation The formulas were calculated and the viscoelastic coefficients of 10 systems were calculated. The experimental results show that the enthalpy relaxation and the coefficient of WLF equation can be determined by DSC.
