摘要:

我们改进了基于热力学热力学定律的爱因斯坦方程精确解的生成方法。首先用Komar质量代替原方法中的Misner-Sharp能量,得到了Einstein方程的几个精确解,其中包括被精粹包围的黑洞解.此外,还得到了由Komar质量定义的几何表面引力.其次,我们用Komar质量和ADM质量对该方法进行了修正,得到了类似的结果。此外,通过对ADM质量的定义进行一些推广,我们的方法可以推广到全局时间。

英文摘要:

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 surrounded by quintessence. Moreover, the geometry surface gravity defined by Komar mass is obtained. 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 added to the definition of the ADM mass, our method can be generalized to global monopole sapcetime.
