摘要:

用分子动力学模拟方法在1573-200K的温度范围内对液态Au的微正则系综进行了模拟研究. 模拟采用镶嵌原子相互作用势对时间和空间的平均,得到了不同温度下Au的偶分布函数及原子组态变化的重要信息,并利用键对分析技术对模拟结果作了深入讨论.

Abstract:

By means of the molecular dynamics simulation technique , a series of simulationsof liquid Au have been performed over the temperature range of l573 K to 200 K. During the simulation process, the EAM potential has been adapted and the pair distribution f1lnction and structure configuration of atom have been obtained. Some simulation results have been discussed by the pair analysis technique.
