中文摘要：

采用外束质子激发X射线荧光、X射线衍射、激光拉曼光谱分析技术,对河南、四川、贵州等地出土的34件汉代耳珰进行了无损伤分析.研究结果表明：这些耳珰中有31件玻璃耳珰,2件骨质耳珰,1件青金石耳珰.玻璃耳珰可以分为：铅钡硅酸盐、铅硅酸盐和钾硅酸盐三种成分体系.结合文献资料,对这批玻璃耳珰的可能来源以及相关各地区间的早期文化、技术交流情况进行了概要讨论.结果显示了科技分析结合考古研究在解决相关考古问题中的作用.

英文摘要：

Combined external-beam proton induced X-ray emission（PIXE） with X-ray diffraction（XRD） and laser Raman spectroscopy analytical techniques,34 pieces of ear pendants dated to the Han Dynasties,which were unearthed from Henan,Sichuan and Guizhou provinces,were analyzed non-destructively.It shows that these ear pendants could be divided into three types-glass,bone and lapis lazuli.Among them,there are 31 pieces glass,two pieces bone and one lapis lazuli ear pendants.The glass ear pendants belong to PbO-BaO-SiO2,PbO-SiO2 and K2O-SiO2 glass systems respectively.Referring to the literatures,we discuss briefly the possible origin of these glass ear pendants,and the relative cultural and technical exchanges between different areas during the early time.The results reveal the value of combination of scientific and technical analysis with archaeological study in resolving relative archaeological questions.
