The area and the surface gravity of black hole event horizon were found to be closely related with the entropy and Hawking temperature. Then four thermodynamic laws were established [1]. Black hole phase transition as a characteristic nature and microstructure indicator has attracted a lot of attention.展开更多

The black hole entropy is contributed by both the area of oilier horizon and the minus area of inner horizon. The entropy satisfies Nernst theorem.展开更多
