微扰技术可以作为超级计算机计算的替代方法来计算碰撞黑洞发出的引力辐射，前提是该过程从黑洞彼此靠近开始。我们总结了各种初始配置（轴对称和非对称）的方法和结果：初始静态、相互推动、反向旋转或以一定角度推动（伪螺旋）。在适用的情况下，我们将扰动结果与超级计算机计算进行比较。
Perturbation techniques can be used as an alternative to supercomputer calculations in calculating gravitational radiation emitted by colliding black holes, provided the process starts with the black holes close to each other. We give a summary of the method and of the results obtained for various initial configurations, both axisymmetric and without symmetry: Initially static, boosted towards each other, counter-rotating, or boosted at an angle (pseudo-inspiral). Where applicable, we compare the perturbation results with supercomputer calculations.
