| 摘 要： | 熄灭率是研究瓷器辐照熄灭特性的一个重要参数,也是衡量一件古瓷器能否用热释光前剂量技术测定的一个重要条件.如果一件瓷器的熄灭率太低,这件瓷器就不能用前剂量技术测定年代,或测定得到的年代结果误差会很大.为此,本工作对中国最早的青瓷——浙江慈溪上林湖唐代、五代及宋代的10个越窑古窑址的78件青瓷样品进行了辐照熄灭率测试研究.测试结果分别获得了各测定样品的“辐照熄灭率”.越窑青瓷样品的平均熄灭率为11.38％,这样的熄灭率保证了热释光灵敏度曲线测量时有足够的分辨率,也保证了应用热释光前剂量熄灭法测定越窑瓷器样品年代结果的准确性.

| Abstract: | Quenching rate is an important factor in radiation quenching studies of porcelains. It is also important for TL predose dating, as low quenching rate leads to large errors or render TL predose dating inapplicable. Radiation quenching rates of 78porcelain samples from Zhejiang Cixi Shanglin Lake were tested. These earliest celadon porcelains were from 11ancient Yue sites of the Tang, the Five dynasties and the Song. The average radiation quenching rate of Yue porcelain samples is 11.4%, which ensures separation of different sensitivity curves and high accuracy of TL ages by the pre-dose quenching technique. |
