论文摘要
字符串是点粒子的一维概括。从这个意义上讲，灰尘云的类似物将是一连串的弦乐。在这项工作中，我们考虑了一般凝胶性围绕常规溶液的一连串弦。我们考虑了Bardeen解决方案和Simpson-Visser解决方案，分析了规律性和能量条件下云的后果。实际上，与辛普森（Simpson）的情况相比，云的存在可能使能量密度呈阳性。我们验证，通常在弦云的存在下，通常的Bardeen解决方案变得单数，而Simpson-Visser解决方案仍然是规律的，违反了能量条件，如通常的解决方案。我们还计算了一些热力学量，以评估云云如何影响溶液的热力学。
A string is the one-dimensional generalization of a point particle. In this sense, the analog of a cloud of dust would be a cloud of strings. In this work, we consider a cloud of strings around a regular solution in general gelativity. We consider the Bardeen solution and the Simpson--Visser solution, analyzing the consequences of the cloud in the regularity and in the energy conditions. Actually, the presence of the cloud could make the energy density positive when compared to the Simpson--Visser case. We verify that the usual Bardeen solution becomes singular in the presence of the cloud of string while the Simpson--Visser solution is still regular, violating the energy conditions, as the usual solution. We also calculate some thermodynamic quantities to evaluate how a cloud of strings influences the thermodynamics of the solutions.
