In optically stimulated luminescence (OSL) dating, the performance of the single-aliquot regenerative-dose (SAR) protocol is commonly tested using a dose recovery test. The dependence of equivalent dose (D_e) determined in a dose recovery test on preheating temperature using quartz OSL was reported in previous studies which demonstrated that using a lower preheating temperature prior to the measurement of the test dose OSL response may result in serious underestimation of the recovered D_e. In this study, we simulate the variation of normalised sensitivity-corrected OSL signals as a function of cycle number and the dependence of the recovered D_e on preheating conditions, using a kinetic model consisting of four electron traps and two recombination centres. Experimentally observed phenomena are successfully reproduced using the model with a set of optimised kinetic parameters. We suggest that the intervention of shallow electron traps may play a significant role in affecting the accuracy of D_e determination. Relevant mechanisms are explained, and implications on dose measurements using the SAR protocol are discussed.

在光学激发发光（OSL）测年中，通常使用剂量恢复测试来测试单等分再生剂量（SAR）协议的性能。先前的研究报道了使用石英OSL在剂量恢复测试中确定的等效剂量（D _e）对预热温度的依赖性，这表明在测量测试剂量OSL响应之前使用较低的预热温度可能会严重低估恢复的D _e。在这项研究中，我们模拟归一化灵敏度校正的OSL信号随循环次数的变化以及所恢复的D _e的依赖性在预热条件下，使用由四个电子陷阱和两个复合中心组成的动力学模型。使用具有一组优化动力学参数的模型，可以成功地复制实验观察到的现象。我们建议浅电子陷阱的干预可能在影响D _e测定的准确性中起重要作用。解释了相关的机制，并讨论了使用SAR协议进行剂量测量的意义。
