摘　　要：中国古玻璃研究的一个重要方面是古玻璃的化学成分分析,它为中国古玻璃的起源和技术发展提供了科学依据,因此,发展新的化学成分分析方法是非常有必要的。便携式能量色散型X射线荧光分析(portable energy-dispersive X-ray fluorescence analysis,PXRF)技术的最大特点就是其便携性,可以对不可移动或难以移出博物馆的文物进行科技分析。文章详细介绍了中国科学院上海光学精密机械研究所科技考古中心与日本OURSTEX公司合作改进的便携式能量色散型X射线荧光分析仪的组成、工作原理及分析过程等,列举了将其应用于新疆出土古玻璃样品的测试结果,并与质子激发X射线荧光分析技术所获结果进行了比较。便携式能量色散型X射线荧光分析技术在现场分析方面具有极为广阔的应用前景。Chemical composition is one of the most important aspects in the study of Chinese ancient glasses,as it could provide scientific proofs for the technical origin and development of Chinese ancient glasses.It is very necessary to find out some new analyzing techniques.One of the most remarkable advantages for portable X-ray fluorescence technique is its portability,which allows antiques that can＇t be allowed to move out of museum to be analyzed.The basic principles,performances and analysis process of the equipment that was improved by OURSTEX company and Center of Sci-tech Archaeology of Shanghai Institute of Optics and Fine Mechanics are presented in detail.Some examples for the application of portable X-ray fluorescence spectrometer in chemical composition analysis of Chinese ancient glass samples excavated from Xinjiang province are also given.The results are compared with that determined by the proton induced X-ray fluorescence technique.There is a potential application for portable X-ray fluorescence technique in on site analysis.
