| 摘 要： | 为了获得低温聚合物的参数和升降温速率对连续升降温无量纲比热容的影响,应用差示扫描量热法(DSC)和TNM的结构松弛模型作出简单的数值研究.结果表明,变换不同比率的升降温速率及不同参数值得到的DSC曲线图形变化能够对聚合物的结构松弛研究有一点参考作用.

| Abstract: | Differential scanning calorimetry(DSC)and the structural relaxation model of Tool Narayanaswamy and Moynihan simple was numerically explored for obtaining the functional influence of the model parameters of the low temperature polymer and the effect of cooling/heating rates on the normalized specific heat capacities.The results indicated that changes in the shape of the curves when using different values of qh and qc relationship and different parameter can be used as an consultion of the structural relaxation of the polymer. |
