我们研究了一类称为裸黑洞的近极端静态黑洞解的性质。这些出现在弦理论中的黑洞，有小的曲率不变量，但在它们的事件视界之外有大的潮汐力。我们表明，这些大的潮汐力是由于集中的质子应力能量附近的地平线。我们研究了下落的测试弦，发现它们受到大潮汐力的高度激发，但仍然很小。也许最重要的是，事实证明，少量的下落物质将导致曲率不变量在视界外变大。然而，精确的计算表明，物质轨道和经典黑洞背景都没有显着改变。
We investigate the properties of a class of near-extreme static black hole solutions called naked black holes. These black holes, which occur in string theory, have small curvature invariants but large tidal forces outside their event horizons. We show that these large tidal forces are due to a concentration of dilaton stress-energy near the horizon. We study infalling test strings and find that they are highly excited by the large tidal forces, but remain small. Perhaps most importantly, it turns out that a small amount of infalling matter will cause the curvature invariants to become large outside the horizon. Nevertheless, an exact calculation shows that both the matter trajectories and the classical black hole background are not significantly altered.
