Data analysis has processed based on the EXAFS analysis program package written in the authors' laboratory. The distances, coordination numbers and Debye-Waller factors between Cu atoms and neighbouring atoms are determined by fitting the experimental data with theoretical phase and backscattering amplitude. The chemical short range order and the atomic neighbouring structure feature of metallic glass Cu_(70)Ti_(30) have been discussed. 收稿日期: 1986-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 常龙存 陆坤权 赵雅琴 韩福森 赵忠贤 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I3/111 1 Wong, J., Topics Appl.
