摘要
利用热释光前剂量技术方法测定瓷器年代,须对瓷器样品进行热激活特性测试,以得到一个最高的测量灵敏度,来提高测定年代的精确度。为此,对慈溪上林湖及周邻地区的狗颈山、低岭头、开刀山、瓦片涯、大路口和寺龙口六处唐、五代与北宋古瓷窑遗址的60件瓷器样品进行热释光年代测量前,进行了热激活特性测定研究。结果表明,上林湖地区的越窑瓷器样品具有非常高的热释光灵敏度,以及比较一致的热激活特性及温度。其中样品的最高热激活温度为700℃,最低热激活温度为640℃,平均激活温度为658℃。在应用前剂量技术测定慈溪上林湖及周邻地区的越窑瓷器样品年代时,采用正确的热激活温度都可以得到一个相对比较准确、可靠的年代结果。
Thermal Activation Characteristic （TAC） tests were performed on sixty porcelain samples from six sites of the Cixi Shanglin Lake area, including Goujingshan, Dilingtou, Kaidaoshan, Wapianya, Dalukou and Silongkou, all dated to the Tang Dynasty, Five Dynasties and Northern Song Dynasty. The result shows that the TL sensitivity of Yue Kiln porcelains is outstandingly high and their TAC and activation temperature remain consistent. The highest thermal activation temperature is 700℃ ;the lowest is 640℃and the average value is 658℃. When measuring the paleo dose and age of Yue Kiln porcelains from the Cixi Shanglin Lake Area using the Pre - dose Technique, accurate and reliable dating information can be obtained by adopting the correct activation temperature.
