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。
The bond parameters of the Fcc-based ordered Al-Li intermetallic compounds and the charge offset of intermetallic bonds were calculated using the Yu’s metallic bond theory. The results show that to form strong Al-Li bonds, Al atoms will shift part of the covalent electrons to Li atom for covalent bonding, and the outer electron state of Al atoms does not change obviously in this process.
