【摘要】：黑洞一直是一個神秘而又令人好奇的天體,但是由于黑洞自身的特性,即所有物質(zhì)及信息都無法從黑洞逃離,給科學(xué)家們研究黑洞帶來了極大的困難。自霍金證明了黑洞有熱輻射以后,人們對黑洞的研究有了更大的進步,同時也說明了黑洞不再是一個“死”的天體.在黑洞物理的研究中,對于黑洞熵的研究一直備受人們關(guān)注.人們運用各種方法求解黑洞的熵,其中,薄膜模型的應(yīng)用最為廣泛。本文從NUT-Taub-Like (NT-Like)時空出發(fā),對NT-Like解的時空性質(zhì)、黑洞的表面引力及其熵等進行了詳細的研究. 若把NT-Like解的時空性質(zhì)與NUT-Taub時空性質(zhì)進行對比,不難發(fā)現(xiàn)：當(dāng)N*M時,它退化為NUT-Taub解的相應(yīng)情況。進一步討論了NT-Like黑洞的表面引力,我們發(fā)現(xiàn),此表面引力與θ角有關(guān),也就是說,一個靜止在NT-Like黑洞外視界的物體(隨視界面一起運動)所受到的引力場強,與θ角有關(guān)。當(dāng)0θπ/2和3π/2θ2π時,NT-Like黑洞的表面引力隨θ角增大而減小,π/2θ3π/2時,黑洞的表面引力隨θ角增大而增大。在計算NT-Likeike黑洞熵時,本文運用了薄膜模型,得出此熵與黑洞表面積成正比(S=A/4),與貝肯斯坦-霍金熵的情況一致。
[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.
