采用三维分子动力学方法对冲击波作用下氩的Hugoniot状态方程进行了数值模拟。数值模拟结果与冲击波和静高压实验数据吻合较好。在此模拟中的熔化转变发生在不超过氩熔化温度的情况下。有两个不连续点可能沿着模拟的氩雨果尼奥特包含固液混合相区域。这是Hugoniot穿过氩熔化曲线的固有特征，并且不需要添加任何固-固相变。
A three-dimensional molecular dynamics simulation of shock wave loading was undertaken to investigate the Hugoniot equation of state at the transition of argon from solid to liquid. The simulated data agree with shock wave and static high-pressure experimental data. The melting transition in this simulation occurs without overshooting the argon melting temperature. There are two discontinuities that may bracket a mixed-phase region of solid and liquid along the simulated argon Hugoniot. This is an intrinsic feature of the Hugoniot crossing the argon melting curve and does not require the addition of any solid-solid phase transition.
