| 摘要: |
| 用余氏金属价键理论计算了Fcc基有序Al-Li金属间化合物的键参量和原子间成键的电荷偏移量。结果表明:要形成较强的Al-Li键,Al原子将偏移部分共价电子给Li原子用于共价成键,而这一过程中Al原子的外层电子状态并没有明显的改变。 |

| Abstract: |
| The bonding parameter and charge deviation of Fcc-base-ordered Al-Li intermetallic compounds have been calculated by using metal valence-bond theory. The results show that in order to form stronger Al-Li bond,there are some charge deviation from Al atom to Li atom to form covalent bond.In this case,there is no evident change in the outer electronic state of Al atom. |
