We find when cooling rate is fast , with the temperature decresing , the number of icosahedron and the relative numbers of 1551 , 1541 bond types related to the icosahedron decrease obviously ; the total number of 1421 , 1422 bond types related to the cubic ( fcc , bcc ) and hcp structures increase obviously ; and the total number of 1311 , 1301 and 1201 bond types related to the rhombohedral structure increase remarkably , and gradually play a dominant role
发现在冷速很快时,随着温度的降低,在ga的微观结构中,二十面体及与二十面体相关的1551 , 1541键型数目明显下降;与立方体( fcc , bcc ) ,六角密集( hcp )结构相关的1421 , 1422键型数目明显增加;而与菱面体相关的1321 , 1311键型的数目却显著增加,逐渐占据优势。
