前剂量中的热激活和辐照熄灭研究

前剂量技术是瓷器热释光测定年代的一个重要方法，它在瓷器中有两个重要特征——热激活效应和辐照熄灭效应。本文根据这两个效应，得到了测定瓷器古剂量的两个方法，一个是“激活法”，另一个是“熄灭法”。研究结果表明，激活法适宜于测定瓷器年代的下限(小于距今100年)，熄灭法适宜于测定瓷器年代的上限(大于距今1000年)。当两个方法同时使用时，瓷器年代测定的准确性将提高。

Thermal activation and radiation quenching effects in pre-dose dating of porcelain

The pre-dose technique is very useful for thermoluminescence dating of porcelain. It incorporates two characteristics in the porcelain dating, i.e. thermal activation and radiation quenching. Two methods, activation method and quenching method, for evaluation of paleodose were introduced. The results show that activation method and quenching method one suitable for dating of lower limit age (less than 100 years B.P.)and upper limit age (greater than 1000 years B.P.), respectively. When both methods are co-used, the dating will be more accurate.
