摘要：

我们分析了5维时空中的一些精确链状黑洞解。与通常的黑弦解和黑环解不同，新解的视界拓扑结构既不是$\mathbb{R}\times R^{2}$也不是$S^1\times S^2$，而是几个拓扑球在单点上相互连接.视界的形状暗示了\emph{black chain of pearls}这个名字，其中每个\emph{pearl}都是链上的拓扑3球。除了通常的黑洞毛发外，这些珍珠可以看作是一条新的黑色珍珠链的毛发。

英文摘要：

We analyze some exact chain-shaped black hole solutions in 5-dimensional spacetime. Unlike usual black string and black ring solutions, the topology of the horizons of the new solutions are neither $\mathbb{R}\times R^{2}$ nor $S^1\times S^2$ but rather like several topological spheres concatenating each other at single points. The shape of the horizon suggests the name \emph{black chain of pearls} on which each \emph{pearl} is a topological 3-sphere on the chain. In addition to the usual black hole hairs, the number of pearls can be viewed as a new hair of the black chain of pearls.
