本章讨论一维可压缩流体动力学的基本要素。这些对于高能量密度物质的行为至关重要。它首先发展理论的冲击波在流体介质中，发展结果的冲击波的任意强度，熵产生的冲击波，斜冲击波，冲击波在接口，并使用飞板驱动冲击波的测量状态方程。本章随后介绍了自相似动力学，它描述了物质的膨胀，也就是所谓的稀薄，也描述了能量短暂沉积产生的冲击波。然后讨论了冲击波和稀薄相互之间以及与密度变化的界面之间的相互作用。
This chapter discusses the fundamental elements of one-dimensional, compressible fluid dynamics. These are essential to the behavior of high-energy-density matter. It begins by developing the theory of shock waves in fluid media, developing results for shock waves of arbitrary strength, entropy generation by shock waves, oblique shock waves, shock waves at interfaces, and the use of flyer plates to drive shock waves for measurements of equations of state. The chapter then introduces self-similar dynamics, which turns out to describe the expansions of matter known as rarefactions, and also to describe the blast waves produced by a brief deposition of energy. It then discusses the interaction of shock waves and rarefactions with each other and with interfaces where the density changes.
