我们考虑一族依赖于任意函数并包含正则视界的弦理论解。他们描述了六维极端黑弦与行波，并有一个不均匀分布的势头沿着字符串。研究了这些解在视界附近的结构，并计算了视界面积。我们还计算了在弱耦合下宏观动量分布与黑弦一致的BPS弦态的数目。结果表明，这种状态的数量是由与行波黑弦的贝肯斯坦-霍金熵。{版权} {美国物理学会}
We consider a family of solutions to string theory which depend on arbitrary functions and contain regular event horizons. They describe six-dimensional extremal black strings with traveling waves and have an inhomogeneous distribution of momentum along the string. The structure of these solutions near the horizon is studied and the horizon area computed. We also count the number of BPS string states at weak coupling whose macroscopic momentum distribution agrees with that of the black string. It is shown that the number of such states is given by the Bekenstein-Hawking entropy of the black string with traveling waves. {copyright} {ital 1997} {ital The American Physical Society}
