膜世界方案是解决如何将高维时空紧致化为四维时空问题的一种新方法。这种情况的显着特点之一是在短距离的经典引力相互作用的高维效应。由于这个特性，在我们的四维世界中存在黑弦解。在本文中，我们假设最简单的具有局部U（1）对称性的复最小耦合标量场模型，证明了在我们的四维世界中，通过I型宇宙长弦的合并过程，黑弦形成的可能性。可能不需要对模型中的参数进行微调。
The brane-world scenario is a new approach to resolve the problem on how to compactify the higher dimensional spacetime to our 4-dimensional world. One of the remarkable features of this scenario is the higher dimensional effects in classical gravitational interactions at short distances. Because of this feature, there are black-string solutions in our 4-dimensional world. In this paper, assuming the simplest model of complex minimally coupled scalar field with the local U(1) symmetry, we show a possibility of black-string formation by merging processes of type I long cosmic strings in our 4-dimensional world. No fine tuning for the parameters in the model might be necessary.
