摘　　要：We modify the method to generate the exact solutions of the Einstein equations basing on the laws of thermodynamics. Firstly, the Komar mass is used to take the place of the Misner-Sharp energy, which is used in the original methods, and then several exact solutions of Einstein equations are obtained, including the black hole solution which is surrounded by quintessence. Moreover, the geometry surface gravity defined by Komar mass is also constructed.Secondly, we use both the Komar mass and the ADM mass to modify such method, and the similar results are obtained.Moreover, with some generalize addition to the definition of the ADM mass, our method can be generalized to global monopole spacetime.We modify the method to generate the exact solutions of the Einstein equations basing on the laws of thermodynamics.
