我们提出了一个奇点切除算法适用于数值模拟的黑洞在整个计算域中移动。该方法是一个扩展的切除程序以前用于获得稳定的模拟单个，不移动的黑洞。切除程序还分享了最近的工作中使用的元素，以研究在一个单一的，助推黑洞的背景下的标量场的动力学。切除方法进行测试与单个黑洞的演化使用的坐标系中的黑洞的坐标位置，从而切除边界，移动整个计算域。
We present a singularity excision algorithm appropriate for numerical simulations of black holes moving throughout the computational domain. The method is an extension of the excision procedure previously used to obtain stable simulations of single, non-moving black holes. The excision procedure also shares elements used in recent work to study the dynamics of a scalar field in the background of a single, boosted black hole. The excision method is tested with single black-hole evolutions using a coordinate system in which the coordinate location of the black hole, and thus the excision boundary, moves throughout the computational domain.
