K0.989Li0.011TaO3 晶体的介电常数测量是在取向玻璃低温相中进行的。通过等温衰变和温度循环研究老化和遍历性破坏。关于样品对温度跃变的响应获得了新的结果：三个具有不同时间尺度的过程得到了证明。这使得可以对先前的实验提出新的解释，特别是提出针对负温度循环观察到的悖论的新解决方案。
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.
