Numerical solutions of the differential equations system describing the transitions between energy levels can help in the understanding of the physical mechanisms governing thermoluminescence (TL) emission but they are not suitable for the analysis of complex experimental TL glow curves. On the other hand, simplified descriptions, as mixed or general order kinetics, require many additional assumptions that may limit the validity of the results or are mostly empirical. In this paper, the accuracy of such approximations has been evaluated for different retrapping-recombination ratios and it has been found that differences between the fitted and the simulated parameters arise from the simplification of the models because quasi-equilibrium condition seems to be valid in all the considered cases.
描述能级间跃迁的微分方程组的数值解有助于理解控制热释光（TL）发射的物理机制，但它们不适用于分析复杂的实验TL发光曲线。另一方面，简化描述，如混合或广义阶动力学，需要许多额外的假设，这些假设可能会限制结果的有效性，或者大多是经验性的。在本文中，针对不同的再俘获-复合比评估了此类近似的准确性，并且发现拟合参数与模拟参数之间的差异源于模型的简化，因为准平衡条件在所有考虑的情况下似乎都是有效的。
