摘要
古代字画的年代决定了字画的价格,其年代的鉴定是收藏界非常关心的问题和难题。本文采用GXNU-AMS(广西师范大学单极静电~(14)C专用AMS)~(14)C测年法(~(14)C-AMS)测定一幅古画的年代。结果显示,GXNU-AMS系统具备良好的测试条件;此古画纸质材料的~(14)C年龄为(489±20)BP,经年轮校正曲线校正后的结果显示属明代早期(1412-1444AD),与古画内容描述的年代相符。
The age of ancient painting determines it's price,and the identification of its age is a big problem that the collectors concerned about.In this paper,an ancient painting sample is measured with the GXNU-AMS(a single stage dedicated accelerator mass spectrometry at Guangxi Normal University),and the ~(14)C age is determined to be the 489±20 BP.The calendar ages of the samples are determined to be in a period from 1412 to 1444 AD(95% confidence level)calibrated with intcal 13,which show that the ancient painting is a product in the early Ming Dynasty.
