虽然广义相对论中的解析近似方法很好地模拟了双黑洞合并的激发阶段和衰变阶段，但数值相对论的最新进展也使我们能够从合并阶段计算出准确的波形。这对寻找来自双星黑洞的引力波具有重要影响。现在，通过将后牛顿波形与数值相对论计算的波形进行匹配，可以生成完全的二进制黑洞波形，数值相对论可以进行参数化，以生成分析波形模板。“完整的”波形还可以用来评估不同搜索方法的效率，这些方法旨在探测来自黑洞聚合的信号。本文综述了近年来在这方面所做的一些工作。
While the inspiral and ring-down stages of the binary black-hole coalescence are well modelled by analytical approximation methods in general relativity, the recent progress in numerical relativity has enabled us to compute accurate waveforms from the merger stage also. This has an important impact on the search for gravitational waves from binary black holes. ‘Complete’ binary black-hole waveforms can now be produced by matching post-Newtonian waveforms with those computed by numerical relativity, which can be parametrized to produce analytical waveform templates. The ‘complete’ waveforms can also be used to estimate the efficiency of different search methods aiming to detect signals from black-hole coalescences. This paper summarizes some recent efforts in this direction.
