摘　　要：采用改进的外束质子激发X射线荧光、电感耦合等离子体原子发射光谱分析等技术,对广西合浦地区出土的一批汉代古玻璃样品的化学成分和结构特性等进行了检测。结果表明:两汉时期,合浦地区的古代玻璃存在K2O-SiO2、PbO-BaO-SiO2、PbO-SiO2、Na2O-K2O-PbO-SiO2、(Na2O)K2O-CaO-SiO2等多种类型,但绝大多数为K2O-SiO2玻璃。表面风化可引起K2O-SiO2玻璃表面K2O等助熔剂的流失和富硅层的形成。综合化学成分以及器型特征,认为我国汉代K2O-SiO2玻璃制造技术可能受到同时期PbO-BaO-siO2玻璃制造技术和外来技术的双重影响。Combining the modified external-beam proton induced X-ray emission （PIXE）, inductively coupled plasma atomic emission spectrometry （ICP-AES） and other techniques, the chemical compositions, structures and other properties of some ancient glass samples of the Han Dynasty, which were unearthed from Hepu county, Guangxi, were determined. These glass samples can be classified to several glass systems, such as K2O-SiO2, PbO-BaO-SiO2, PbO-SiO2, Na2O-K2O-PbO-SiO2 and （Na2O）K2O-CaO-SiO2. But most of the samples belong to K2O-SiO2 system glass. Due to the surface corrosion, the flux K2O in the surface of the K2O-SiO2 glass was lost, but with the relative enrichment of the SiO2. Based on the characteristics of chemical composition and appearance of these samples, it is thought that, during the Han Dynasty, the making technique of the K2O-SiO2 glass in China was influenced by the technique related to the PbO-BaO-SiO2 glass from abroad.
