We have analyzed a property and stability of new type of black holes, which do not belong to the Kerr-Newman family. In a unified theory of fundamental interactions, we usually expect non-Abelian gauge fields, which provide us new types of non-trivial structure like a monopole and new black holes. We have classified those black holes and presented a unified picture. We have also shown that the stability of those black holes is understood by a catastrophe theory, when the entropy of a black hole is regarded as the potential function.The qunatum radiation process of black holes has also been studied in theories with a dilaton field, which is inspired by a unified theory. A superstring model turns out to be critical in a sense that the energy flux of Hawking radiation diverges if the dilaton coupling with U (1) gauge field is larger than that of the superstring model.

我们已经分析了不属于克尔·纽曼家族的新型黑洞的财产和稳定性。在基本互动的统一理论中，我们通常期望非亚伯仪范围领域，这为我们提供了新型的非平凡结构，例如单子和新的黑洞。我们已经对那些黑洞进行了分类，并提出了统一的图片。我们还表明，当黑洞的熵被视为潜在功能时，这些黑洞的稳定性是由灾难理论理解的。黑洞的Qunatum辐射过程还以Dilaton领域的理论进行了研究，这是受统一理论的启发。从某种意义上说，如果霍金辐射的能量通量与u（1）量规场大于SuperString模型，那么superstring模型至关重要。
