Radial distribution function of alloy was decomposed by 5 Gaussian peaks, and the elfed of Sron the alloy's liquid structure was investigated. The result showed that Si--Si covalent bond eAsts in the melt of eutectic and hyper--eutectic alloy and Sr has capability to weaken the coto bond. Key words:  Al--Si alloy      covalent bond      liquid structure      X--ray diffraction      Received:  18 June 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I6/645 1 张瑞林,固体与分子经验电子理论,长春:吉林科学技术出版社.1993:279 (Zhang R L.The empricial electron theory of solid and molceules ,Changchun :Jilln Schence Prees 1993:279) 2 Singh M, Kumar R.J Moter Sci 1973; 8: 317 3 Kita Y, Zytveld J B Van, Morita Z, Iida T.J Phpa: Condens Mattert 1994; 6: 811-830 4 Waseda Y,The Structure of non-crystalline materials New York :Mc-GRAW-Hill ,1981:9,54 5 Stich I, Car R, Parrinello M.
