摘要
通过对非晶高聚物动态力学方法和前人的静态法（如膨胀计法或量热法）实验结果的比较，指出：用静态法测得的玻璃化转变温度Ｔｇ和用动态力学法测得的α内耗峰的峰温Ｔα虽然在温度上很接近，但物理本质不同，并对引起这种不同的微观物理机制作了一定的探讨．
Comparision between the results by dynamic mechanical and static methods has been made. The resoults show clearly that the T g determined by calorimetry or dilatometry and the peak temperature T α obtained by dynamic mechanical method have different physical origins, although T α is usually in the vicinity of T g. It is suggested that during dynamic mechanical measurement, two different processes (thermal relaxation and mechanical relaxation) be involved in simultaneously.
