摘　　要：采用常规的热释光细粒混合矿物法、热释光前剂量饱和指数法以及单片再生剂量光释光法三种测年方法 ,对中国上海、浙江萧山地区出土的 7件西周、春秋、战国以及汉代的原始瓷样品进行了年代测定 ,并对测得的每个样品的 3个年代结果与已知年代进行比对。用热释光细粒混合矿物法测定得到了较为理想的年代结果 ,与样品的已知年代结果相比吻合得较好。用热释光前剂量饱和指数法测定得到了该方法的上限饱和年代 ,即距今 180 0年左右。用再生剂量光释光法测定得到了这些样品的年代 ,只是实际年代的 5 0 %— 80 %左右 ,结果不太理想。因此 ,采用热释光细粒混合矿物法测定这类样品的年代 ,只要解决了制样问题 ,还是目前较好的测年方法。Fine Grains Method,Predose Regression Method and Single Aliquot Regeneration Method(SAR)were used to authenticate sample's age.Seven samples with known age,from Western Zhou,Spring & Autumn,Warring States to Han Dynasty,which were excavated from Shanghai and Xiao Shan region of Zhejiang province in China.The samples' ages evaluated by these methods were compared with its archaeological age.Fine Gains Method provided satisfactory result that was the closest to the archaeological age.Ages authenticated by Predose Regression Method were limited to about 1800 yrs that was due to saturation while ages evaluated by SAR Method ranged from 50% to 80% of the archaeological age.Thus,Fine Gains Method is found to be the best applicable method to be sued to authenticate the age of China primitive porcelain.
