Abstract

Zel’dovich and Polnarev, in their seminal paper (Zel’dovich and Polnarev, 1974) suggested that a gravitational wave generated by flyby would merely displace the particles. We confirm their prediction numerically by fine-tuning the wave profile proposed by Gibbons and Hawking (1971), and then analytically for its approximation by a Pöschl–Teller potential. Higher-order derivative profiles proposed for gravitational collapse, etc (Gibbons and Hawking, 1971) are shortly discussed.

位移记忆飞掠

泽尔多维奇和波尔纳列夫在他们的开创性论文（泽尔多维奇和波尔纳列夫，1974年）中提出，飞掠产生的引力波只会使粒子位移。我们通过微调吉本斯和霍金（1971）提出的波剖面，在数值上证实了他们的预测，然后用Pöschl-Teller势对其进行分析近似。本文简要讨论了引力坍缩等（Gibbons和Hawking， 1971）提出的高阶导数曲线。
