摘　　要：同步辐射装置作为大科学装置和多学科的实验平台,已成为物质结构,特别是无序物质结构研究最有效、最先进的手段之一.文章简单介绍了同步辐射技术在研究无序合金结构、液态合金结构、非晶多形态相变以及块体金属玻璃力学行为等方面的应用.随着第三代的上海同步辐射光源(SSRF)的建立,国内用户利用先进的同步辐射技术开展研究又多一个选择,相信上海光源对中国科研的发展将起到积极的推动作用.Synchrotron radiation-based techniques have become a powerful and advanced tool for studying the structure of materials, especially disordered materials. We report some applications of synchrotron radiation-based techniques in studies of the atomic structures of disordered alloys and liquids, pressure-induced phase transformation in disordered alloys, and the mechanical behavior of disordered alloys. With the development of the third generation Shanghai Synchrotron Radiation Facility （SSRF）, many researchers in China will explore and employ its advanced facilities for multidisciplinary research. The SSRF should play a positive and far-reaching role in the promotion of scientific research work in China.
