摘　　要：计算了两个Schwarzschild黑洞视界的高斯曲率、赤道周长和极向周长。研究了这些量随两个黑洞之间的距离不同而产生的变化。结果表明两个黑洞中的一个对另一个视界几何性质的影响。The Gaussian curverture, equatorial and polar circumferences are calculated for the event horizons of two Schwarzschild black holes. Their variations following the change of the distance of two black holes are also examined. The results show that the geometrical property of the horizon of one black hole is affected by the other.

关 键 词：黑洞 视界几何性质 总曲率
