摘要：

在高维Einstein-Yang-Mills理论中，给出了一类具有p-紧维数的非渐近平坦（NAF）带电黑p-膜（BpB）.渐近NAF结构表现为反德西特时空。我们确定了位于事件视界外的薄壳层中的总质量/能量。通过比较BpB与同维黑洞的熵，我们得到了两类黑天体之间的跃迁判据。在一定条件下，我们的分析表明BpB可以看作是黑洞的激发态. BpB的事件视界$r_{+}$与电荷平方$Q^{2}$的关系图揭示了这样一个跃迁，其中$r_{+}$与黑洞（BH）的视界半径$r_{h}$有关，两者都带有公共电荷$% Q. $

英文摘要：

We present a class of non-asymptotically flat (NAF) charged black p-branes (BpB) with p-compact dimensions in higher dimensional Einstein-Yang-Mills theory. Asymptotically the NAF structure manifests itself as an anti-de-sitter spacetime. We determine the total mass / energy enclosed in a thin-shell located outside the event horizon. By comparing the entropies of BpB with those of black holes in same dimensions we derive transition criteria between the two types of black objects. Given certain conditions satisfied our analysis shows that BpB can be considered excited states of black holes. An event horizon $r_{+}$ versus charge square $Q^{2}$ plot \ for the BpB reveals such a transition where $r_{+}$ is related to the horizon radius $r_{h}$ of the black hole (BH) both with the common charge $% Q. $
