However, fractal language has been more and more frequently used to describe some disordered physical systems except liquid alloys. This paper has successfully implemented fractal ideas to observe fractal structures in liquid In-Sn alloy and considers its fractal dimension as a physical quantity sensitive to structure. Moreover, from the fractal viewpoint, the mutation of the fractal dimension has indicated once again that the liquid structure change discontinuously with temperature rising. Key words： liquid alloys structure    fractal theory    temperature-induced 收稿日期: 2006-04-04      ZTFLH:  O552.41   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 丁国华 祖方遒 余谨 席赟 张燕 44.8K 链接本文: https://www.ams.org.cn/CN/Y2006/V42/I12/1259 [1] Gefen Y, Mandelbrot B B.
