论文摘要
提出了一种附着在黑洞上的宇宙字符串（即圆锥形奇异点）的新模型。这些字符串是通过从所谓的Bonnor Rocket的限制过程中明确结构获得的。这表明其应力能量张量的性质非常令人惊讶，其中包含DIRAC $δ$分布的第一个衍生物。从邦诺火箭开始，我们明确构建了Schwarzschild解决方案Witch Conical Singularity和C-Metric。在后一种情况下，我们表明，宇宙弦的动量通量，导致黑洞的加速度，并且这种动量的数量与重力辐射所取消的动量一致。
A new model for cosmic strings (i.e. conical singularities) attached to black holes is proposed. These string are obtained by a explicit construction via limiting process from the so-called Bonnor rocket. This reveals quite surprising nature of their stress-energy tensor which contains first derivative of Dirac $δ$ distribution. Starting from the Bonnor rocket we explicitly construct the Schwarzschild solution witch conical singularity and the C-metric. In the latter case we show that there is a momentum flux through the cosmic string, causing the acceleration of the black hole and the amount of this momentum is in agreement with the momentum taken away by gravitational radiation.
