| 摘 要： | 文中用分子动力学方法研究了具有面心结构的晶体在冲击波的作用下温度、压力、粒子速度、物质密度及冲击波速度诸参数的变化,并与宏观规律作了比较。文中采用Fincham的计算格式。原子间的相互作用势用Morse势,其参数用最近邻相互作用近似获得。

| Abstract: | Molecular dynamic techniques were used to study the changes of the temperature, pressure, particle" velocity, density and shock wave velocity on fcc crystals acted by shock wave. The results were compared with macroscopic law. Fin-cham's calculation form was adopted in this paper. Morse potential was taken as the interaction potential between two atoms and its parameters were obtained approximately by the nearest neighbor interaction. |
