摘要：

The use of different models to interpret results obtained from thermally stimulated depolarisation current experiments (TSDC) is discussed. It is shown that the compensation temperature T-c introduced in the TSDC model (compensation law) and the fictive equilibrium temperature T-fi used to characterise the thermal model are identical. The discussion is illustrated by different measurements carried out on a polyethylene terephthalate (PET).
