利用激光驱动冲击压缩技术获得了高达260 GPaH2O的压力、密度和温度数据。采用激波压缩技术和钻石顶盒相结合的方法，对主Hugoniot态和Off-Hugoniot态的P-Rho-T条件的状态方程模型进行了评估。通过模型之间的对比，可以清楚地评估状态方程模型。我们的P-Rho-T数据与基于量子分子动力学计算的模型的数据完全一致。这些事实表明，该模型被用作模拟海王星、天王星和系外行星在多Mbar范围内液态的内部结构的标准。(C)2015 AIP出版有限责任公司。
Pressure, density, and temperature data for H2O were obtained up to 260 GPa by using laser-driven shock compression technique. The shock compression technique combined with the diamond anvil cell was used to assess the equation of state models for the P-rho-T conditions for both the principal Hugoniot and the off-Hugoniot states. The contrast between the models allowed for a clear assessment of the equation of state models. Our P-rho-T data totally agree with those of the model based on quantum molecular dynamics calculations. These facts indicate that this model is adopted as the standard for modeling interior structures of Neptune, Uranus, and exoplanets in the liquid phase in the multi-Mbar range.
