摘要
用分子动力学模拟技术计算出合金熔体的原子坐标， 再利用动画演示技术将熔体原子直观地显示出来， 形成微观液体金属原子运动的物理图象。揭示液体金属原子不是孤立存在的， 而是形成许多原子集团。熔体的双体分布函数显示出液体长程无序、短程有序的重要特征。
The atom coordinates of Fe\-3Al alloy melt have been calculated by using computer simulation of molecular dynamics and then animation display technique is used to show directly the atoms of alloy melt,thus obtaining physical images of microstructural movement of liquid metal atoms.The liquid metal atoms are found not to exist separately,but to form some atom groups,the pair distribution function of Fe\-3Al melt is characterized by irregularity in far neighbor and regularity in near neighbor.
