我们扩展了我们最近对带行波的极值黑弦熵的分析。我们之前考虑过在六维的黑弦上携带线性动量的波。这里我们研究在这些弦上携带角动量的波，以及在五维黑弦上携带线性动量的波。在这两种情况下，我们证明视界保持均匀并计算其面积。我们还计算了具有相同线动量和角动量分布的弱弦耦合下的BPS态的数量，并发现与黑弦熵完全一致。
We extend our recent analysis of the entropy of extremal black strings with traveling waves. We previously considered waves carrying linear momentum on black strings in six dimensions. Here we study waves carrying angular momentum on these strings, and also waves carrying linear momentum on black strings in five dimensions. In both cases, we show that the horizon remains homogeneous and compute its area. We also count the number of BPS states at weak string coupling with the same distribution of linear and angular momentum, and find complete agreement with the black string entropy.
