使用烈性炸药将强烈冲击波驱动到各种液体中，并使用移动图像相机来确定与冲击波相关的速度。通过应用守恒关系将测量的速度转换为压力压缩点。研究的 15 种液体所达到的压力各不相同，但通常在 50 kilobar 至 150 kilobar 范围内。对于水，更广泛的实验足以确定 30 kilobar 到 450 kilobar 的 Hugoniot 曲线。每种液体的最高压力将静态实验的可用数据范围扩展了几倍。描述了一种冲击波反射实验方法，其目的是测量高压下有用的热力学变量 (ΔH/ΔV)P。给出了水的结果。报告了研究冲击水、四氯化碳、乙醇和苯透明度的定性实验。
High explosives were used to drive strong shock waves into various liquids, and a moving‐image camera was employed to determine velocities associated with the shock waves. The measured velocities are transformed to pressure‐compression points by applying the conservation relations. The pressures attained vary among the 15 liquids studied but are typically in the range 50 kilobars to 150 kilobars. For water, more extensive experimentation suffices to determine the Hugoniot curve from 30 kilobars to 450 kilobars. The highest pressure for each of the liquids extends the available data range from static experimentation several fold.A shock‐wave‐reflection experimental method is described, the purpose of which is to measure the useful thermodynamic variable (ΔH/ΔV)P at high pressures. Results are given for water.Qualitative experiments to study the transparency of shocked water, carbon tetrachloride, ethyl alcohol, and benzene are reported.
