我们提出了一个新的表达式的五维静态Kaluza-Klein黑洞的解决方案与压缩S3视界和三个不同的电荷参数。该黑洞解属于D= 5，N= 2的超引力理论，其时空是局部渐近平坦的，具有空间无穷大R× S1 <$S2。该解的形式非常简单，并能很方便地用反项法计算其守恒电荷。进一步表明，如果紧致额外维的长度可以看作是一个物理变量，那么我们的物理量完全服从黑洞热力学的微分和积分第一定律.
We present a new expression for the five-dimensional static Kaluza–Klein black hole solution with squashed S 3 horizons and three different charge parameters. This black hole solution belongs to D= 5, N= 2 supergravity theory, its spacetime is locally asymptotically flat and has a spatial infinity R× S 1↪ S 2. The form of the solution is extraordinary simple and permits us very conveniently to calculate its conserved charges by using the counterterm method. It is further shown that our thermodynamical quantities perfectly obey both the differential and the integral first laws of black hole thermodynamics if the length of the compact extra-dimension can be viewed as a thermodynamical variable.
