我们研究了理想流体中受扰动的球形内爆激波的性质，通过崩塌、反弹和发展成出射激波。当以相同的半径观察时，我们发现传入和传出微扰的大小和形状是广泛守恒的。发出的激波恢复了强烈扭曲的核心外未受扰动的激波的速度。这些结果是在激波点火方法对惯性聚变能量的稳健性的背景下提出的。
We examine the properties of perturbed spherically imploding shock waves in an ideal fluid through the collapse, bounce, and development into an outgoing shock wave. We find broad conservation of the size and shape of ingoing and outgoing perturbations when viewed at the same radius. The outgoing shock recovers the velocity of the unperturbed shock outside the strongly distorted core. The results are presented in the context of the robustness of the shock ignition approach to inertial fusion energy.
