摘　　要：本文报道了用ENGLE-II微探针能量色散型X荧光光谱(EDXRF)技术测定一批青瓷残片中的16种元素氧化物的含量,其残片来自浙江杭州地区南宋的郊坛窑和老虎洞窑。由主量元素判别方程Q值表明,郊坛和老虎洞青釉瓷均属官窑制品,与龙泉民窑产品有很大差别。从主成分统计分析看出,郊坛下官窑与老虎洞官窑的瓷釉成分有明显不同,但其胎质成分的分布却有部分的重叠。这显示两类同属官窑的制品,其釉料可有不同的矿物组合,但胎料有时会交流使用。从釉层、中间层、和胎层的Al2O3和CaO的含量变化数据表明,郊坛下官窑和老虎洞官窑的青瓷制品有厚度分别为120-140μm和230-240μm的中间层,反映出烧造工艺上有一定的差别。化学成分鉴定证实了考古工作者认为老虎洞窑实为史书记载的修内司官窑的观点。The chemical contents in the glaze layer, interlayer and body layer of the South Song Dynasty celadon from the Altar and Laohudong Yao in Hangzhou City, Zhenjiang Province have been determined using EAGLE-If microprobe EDXRF equipment. The Q values of the sampling celadon are larger than 8, which mean that the Altar and Laohudong porcelains belong to the official products. The principal cnmponent analysis shows that the chemical characters of the glaze between the Altar and Laohudong celadon are much difference. The workers might take the local material to manufacture their celadon. The sudden distance reflected in the Al2O3 and CaO contents between the glaze and body layers can be defined as a thickness of the interlay. The interlay thickness between the Ahar and l.aohudong celadon appears in lOOp. m difference, which may relate with the chemical composition, diffusive behavior of the elements and the firing temperature. The firing temperature for making the Laohudong porcelains is a little higher than that for making the Altar wares.
