摘　　要：为系统了解历代上林湖地区越窑青瓷胎釉化学组成的特点,本研究采用能量色散X射线荧光光谱技术(EDXRF),对唐代、五代、北宋和南宋上林湖越窑青瓷作了分析。分析结果表明,越窑胎釉组成是低铝高硅的南方青瓷特征,有一定量的杂质,历代瓷釉均为高钙釉;从唐代到南宋,越窑青瓷胎的化学组成未发生明显的变化,但唐代青瓷、北宋透明釉青瓷、南宋乳浊釉青瓷釉的化学组成存在一些差异;南宋越窑部分青瓷的外观虽然发生了变化,但釉料仍延续了越窑独特的工艺配方,与北方青瓷和南方官窑青瓷等的釉料差异明显。分析同时表明:该技术的使用为解决薄釉的样品处理难题提供了一条途径。Energy dispersive X- ray fluorescence （EDXRF） was used to systematically analyze the chemical compositions of the body and glaze of the 53 pieces porcelains made in the Yue klin in the Shanglinhu area during the Tang Dynasty, Five Dynasties, and Northern and Southern Song Dynasties. The porcelain had a high content of SiO2 but had a low content in Al2O3 , a body and glaze. All Yue porcelain feature characteristic of Southern porcelain wares, and there are some inclusions in glazes had a high amount of calcium during those dynasties. From Tang to South- ern Song, the chemical composition of the porcelain body did not change significantly, but there were differences between the Tang porcelain glaze, the transparent Northern Song porcelain glaze and the opaque Southern Song porcelain glaze. Although there were appearance modifications in some Southern Song porcelain, thechemical composition suggested that the unique production technology of Yue klin, which was significantly different from that in the Northern and the Southern Guan klins, had been maintained. The analysis also indicates that the EDXRF has the advantages of surface layer analysis, being non - destructive with a relatively short testing time and high accuracy. It is a good method for studying porcelains with thin glazes.
