摘要：

Dielectric constant measurements of a K0.989Li0.011TaO3 crystal are performed in the orientational glass low-temperature phase. Aging and ergodicity breaking are studied through isothermal decays and temperature cycles. New results are obtained on the response of the sample to temperature jumps: three processes, with very different time scales, are put in evidence. This allows to propose a new interpretation of previous experiments and, in particular, to present a new solution of the paradox observed for the negative temperature cycles.
