摘要
叙述了热释光断代中采用前剂量技术测定瓷器的年代，着重研究了瓷片深度剂量的变化，１１０℃ＴＬ峰的热激活特性、古剂量的测定和年剂量的估算。结果表明，这项技术能用于古代瓷器的真伪鉴定，但准确度和精密度不及陶器。另外，前剂量技术中一些复杂因素，也是导致年代测定误差大的可能原因。
The age determination of ancient porcelain using the pre-dose technique in TL dating was reported. The variation of beta dose with depth below the surface of the porcelain slice, the thermal activation characteristic(TAC) for 110℃ peak, the measurement of paleodose and the estimation of annual dose were studied. The results show that this technique is suitable for authenticity testing of ancient porcelain, but both accuracy and precision for porcelain dating are worse than those for pottery, because porcelain differs from pottery on composition, structure and firing temperature. Besides, some complicated factors in the pre-dose technique would be the possible cause of the greater errors.
