通常的热刺激电流谱是等速升温测量结果，但解谱时要假设热平衡态的两个基本方程成立，若改进为采用阶跃升温方法，则可不必用这两个假设；实验将直接给出冷冻下来的极化电荷和弛豫时间随温度的变化，以聚丙烯为例对两种方法的测量结果作了比较．
The usual thermal stimulation current spectrum is a constant temperature measurement results, but the solution spectrum to assume that the two basic equations of the thermal equilibrium state established, if improved to step-by-step heating method, you may not need to use these two assumptions; experiment will be direct The frozen charge polarization and relaxation time with temperature changes to polypropylene as an example of the results of the two methods were compared.
