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.
进行了冲击波加载的三维分子动力学模拟，以研究氩从固态转变为液态时的雨贡纽状态方程。模拟数据与冲击波和静态高压实验数据相符。在该模拟中，熔化转变发生时并未超过氩的熔化温度。沿着模拟的氩雨贡纽曲线，存在两个间断点，它们可能界定了固液混合相区域。这是雨贡纽曲线穿过氩熔化曲线的一个固有特征，不需要添加任何固-固相变。
