THE PLANCK ABSOLUTE ENTRORY OF THE BLACK HOLE
黑洞的普朗克绝对熵公式

LI CHUAN-AN,

物理学报 , 2001,
Abstract: Using the first and third law of the black hole mechanics, we have derived the formula of the Planck absolute entrory of the black hole. The formula represents that the entrory of the black hole should be proprotional to the total area of the inner and outer horizons. And we have proven that the Planck absolute entrory of the black hole should be the classical thermodynamic entropy.

Abstract: The general event horizon formula of black hole is given from null hypersurface equation.We prove that this formula is correct by Klein-Gordon equation,and we obtain yet the event horizon equation of arbitrarily accelerated black hole containing charges by using of this formula.
Information entropy for static spherically symmetric black holes

Jiang Ji-Jian,Li Chuan-An,

中国物理 B , 2009,
Abstract: By using the new equation of state density derived from the generalized uncertainty relation, the number of the quantum states near event horizon is obtained, with which then the information entropy of static spherically symmetric black holes has been discussed. It is found that the divergent integral of quantum states near the event horizon can be naturally avoided if using the new equation of state density without introducing the ultraviolet cut-off. The information entropy of black holes can be obtained precisely by the residue theorem, which is shown to be proportional to the horizon area. The information entropy of black holes obtained agrees with the Bechenstein--Hawking entropy when the suitable cutoff factor is adopted.

Abstract: Kerr black hole has only two parameters of M and J. M and J, as the general coordinates, together with their conjugate variables form a four-di mensional phase space. The quantum area spectrum of Kerr black hole is obtained by performing gauge transformations, from which we can obtain the smallest mas s of Schwarzchild black hole.

物理学报 , 2005,
Abstract: Using the improved brick-wall model,the writers of the article have made some r esearches in the contribution made by the high spinning gravitation field to sta tic ball-symmetry black hole entropy. The research shows that in the static bal l-symmetry black hole, the quanta entropy of the gravitation field in whitch th e spinning is 2 is still in direct proportion to the horizon. When the same trun catin genes as theose in scalar guantity field are selected the quanta entropy i s two times in scalar quantity field, and four-sevenths of those in Dirac field .

物理学报 , 2003,
Abstract: In terms of the improved brick-wall model, the statistical entropy of Dirac field in the most general spherically symmetric non-static black hole is calculated. It is shown that the entropy of the black hole is proportional to the area of event horizon at any time. It is noteworthy that the calculating formula for the dynamic proportional coefficient is obtained in this paper. Through calculating these dynamic proportional coefficients, the statistical entropies of the Dirac field in all kinds of the spherically symmetric non-static black hole can be obtained directly.

物理学报 , 2010,
Abstract: Using entropy density of scalar field near event horizon in an arbitrarily accelerating black hole with electric charge and magnetic charge,we study the law for the thermal radiation of black hole and the instantaneous radiation energy flux is obtained. It is found that the thermal radiation of a black hole always satisfies the generalized Stefan-Boltzmann's law. The proportional coefficient of generalized Stefan-Boltzmann is no longer a constant,and it becomes a dynamic coefficient that is related to the p...
