通过对具有质量多极矩的静态黑洞视界附近的Hawking辐射的研究,发现这类黑洞的存在将违背黑洞热力学定律.对这类引力场进行线性微扰,发现在尘埃物质扰动下,这类黑洞是不稳定的.故宇宙中可能不存在具有质量多极矩的静态黑洞.By studying the Hawking radiation near the horizon of a static black-hole with a multipole moment, we find that its existence would violate thermodynamic laws of black-hole. Under a perturbation of dust, this kind of gravitational field is unstable. So we guess that this kind of black-hole does not likely exist in the universe.
