摘 要: 采用统计学描述方法,从泊松分布导出的响应函数作为热释光剂量响应的基本方程,将线性、亚线性和超线性响应进行统一的描述。响应函数的特征参量,一次作用因子R和特征剂量D0,既有清楚的统计学含意又有明确的剂量学意义。结合热释光过程的微观机制很好地解释热释光剂量响应非线性相关的一系列实验结果。 It is assumed that a dose response function derived from the statistical poisson distribution can be used to describe the TL dose responses. Two parameters in this function, one--hit factor R and characteristic dose D0, not only have statistical meaning but also contain dosimetric significance. When coupling with the microscopic mechanism for the TL process, dominant features of the nonlinear phenomena observed in experiments can be explained.
