【摘要】：黑洞一直是一个神秘而又令人好奇的天体,但是由于黑洞自身的特性,即所有物质及信息都无法从黑洞逃离,给科学家们研究黑洞带来了极大的困难。自霍金证明了黑洞有热辐射以后,人们对黑洞的研究有了更大的进步,同时也说明了黑洞不再是一个“死”的天体.在黑洞物理的研究中,对于黑洞熵的研究一直备受人们关注.人们运用各种方法求解黑洞的熵,其中,薄膜模型的应用最为广泛。本文从NUT-Taub-Like (NT-Like)时空出发,对NT-Like解的时空性质、黑洞的表面引力及其熵等进行了详细的研究. 若把NT-Like解的时空性质与NUT-Taub时空性质进行对比,不难发现：当N*M时,它退化为NUT-Taub解的相应情况。进一步讨论了NT-Like黑洞的表面引力,我们发现,此表面引力与θ角有关,也就是说,一个静止在NT-Like黑洞外视界的物体(随视界面一起运动)所受到的引力场强,与θ角有关。当0θπ/2和3π/2θ2π时,NT-Like黑洞的表面引力随θ角增大而减小,π/2θ3π/2时,黑洞的表面引力随θ角增大而增大。在计算NT-Likeike黑洞熵时,本文运用了薄膜模型,得出此熵与黑洞表面积成正比(S=A/4),与贝肯斯坦-霍金熵的情况一致。
[Abstract]:Black hole has always been a mysterious and curious object, but because of its own characteristics, that is, all matter and information can not escape from the black hole. It is very difficult for scientists to study black holes. Since Hawking proved that black holes have heat radiation, people have made great progress in the study of black holes. At the same time, it also shows that black hole is no longer a "dead" celestial body. In the study of black hole physics, the study of black hole entropy has been paid much attention. People use various methods to solve the entropy of black hole. The film model is the most widely used. In this paper, the space-time properties of NT-Like solution are discussed from the point of view of NUT-Taub-Like NT-Like space-time. The surface gravity and entropy of black hole are studied in detail. If we compare the space-time properties of NT-Like solutions with those of NUT-Taub, it is not difficult to find out that: when NT-Like is M, it is not difficult to find. It degenerates to the corresponding case of the NUT-Taub solution. The surface gravity of the NT-Like black hole is further discussed. We find that the surface gravity is related to the 胃 angle, that is, the surface gravity of the NT-Like black hole is related to the 胃 angle. The gravitational field of an object standing at the outer horizon of a NT-Like black hole (moving with the visual interface) is strongly related to the 胃 angle, when 0 胃蟺 / 2 and 3 蟺 / 2 胃 2 蟺. The surface gravity of NT-Like black hole decreases with the increase of 胃 angle, while that of 蟺 / 2 胃 3 蟺 / 2:00 increases with the increase of 胃 angle. The entropy of NT-Likeike black hole is calculated. Using the thin film model, it is found that the entropy is proportional to the surface area of the black hole and is in direct proportion to the surface area of the black hole, which is consistent with the case of the Bakenstein Hawking entropy.
