研究了Cu-Zn-Al合金中热驱动结构相变间歇动力学过程中时间相关性的存在。雪崩的顺序观察通过两种技术：声发射和高灵敏度量热法。这两种方法都揭示了事件聚类的存在，其方式相当于地震学中常用的余震之间的大森相关性。
The existence of temporal correlations during the intermittent dynamics of a thermally driven structural phase transition is studied in a Cu–Zn–Al alloy. The sequence of avalanches is observed by means of two techniques: acoustic emission and high sensitivity calorimetry. Both methods reveal the existence of event clustering in a way that is equivalent to the Omori correlations between aftershocks in earthquakes as are commonly used in seismology.
