选取秦始皇陵一号坑的陶俑和陶马样品20个,秦始皇兵马俑博物馆附近粘土样品20个,耀州瓷胎样品1个。用中子活化分析 (NAA) 方法测量了样品中32种微量元素的含量,将这些数据进行模糊聚类分析,得到动态聚类分析图。结果表明,这些兵马俑的原料来源可能为骊山地区的粘土,由此推断烧制兵马俑的窑址也可能在秦始皇陵附近。
Totally 20 samples of clay figurines and pottery from Pit No.1 in Qin Shi Huang Mausoleum, 20 clay samples near Qin Terra-Cotta Warriors and Horses Museum and 1 porcelain sample from Yaozhou were selected. The content of 32 trace elements in the sample was measured by neutron activation analysis (NAA). The data were analyzed by fuzzy clustering to get the dynamic cluster analysis diagram. The results show that the origins of these terracotta warriors and horses may be the source of clay in Lishan area, which concluded that the kiln site firing terracotta warriors may also be in the vicinity of the Qin Shi Huang Mausoleum.
