我们讨论了 PbMg1/3Nb2/3O3–PbTiO3 (PMN-PT) 单晶中热受激声发射 (AE) 的性质。特别是，我们推导了一个描述 AE 效率的表达式，并就此讨论了来自纯 PMN 的 AE。我们进行了原始实验，揭示了 PMN-PT 中的声发射对电偏压场的依赖性，并且我们发现通过施加电偏压场，PMN-PT 的声发射效率可以在一定温度区间内大大提高。
We discuss the nature of the thermally stimulated acoustic emission (AE) in single crystals of PbMg1/3Nb2/3O3–PbTiO3 (PMN-PT). In particular, we derive an expression describing the efficiency of AE and we discuss in this connection AE from pure PMN. We have carried out original experiments revealing the dependence of AE in PMN-PT on the electric bias fields, and we found that the AE efficiency of PMN-PT can be heavily enhanced in a certain temperature interval by applying an electric bias field.
