Abstract


Theory and observation since the black hole General relativity predicts , researchers have done a lot of work , trying to reveal the nature of black holes and the origin of black hole entropy statistics . This paper studies the use of correction to any order of the Planck length equation of state density calculation the static SPACETIME statistical entropy . In the first chapter , we first introduce the origin of the black hole and its formation process , and then introduced the basic concepts and theory of black hole science , followed by a discussion of the statistical origin of black hole entropy . In the second chapter , we summarized solving the two models of black hole entropy ( brick wall model and film model ) , and describes the applicable conditions of the two models ; to the Schwarzschild SPACETIME and static deSitter SPACETIME use two models for solving the entropy of the scalar field to draw statistical entropy of black hole space - time quantum field and its surface area is proportional to the conclusion ; final summary of the characteristics of both models and the analysis of the encounter in the course of the study cutoff and entropy divergence . The third chapter introduces the author 's own work . First introduced the generalized uncertainty relation for position and momentum , and thus get the position of the minimum uncertainty ; amend the equation of state density corresponding micro- state relations based on the promotion of easy , the use of the equation of state density after correction the black hole outside material field of quantum states the number at the horizon is convergence ; Finally, the amendments to the Planck length of any order of the density of states equation application to the Schwarzschild-deSitter black hole space-time scalar field statistical entropy of calculation and Reissner-Nordstrom black hole space-time Dirac field statistics entropy calculation .
