| 摘 要： | We study quarkand strangequarkmatter in the contextof generalrelativity.For this purpose,we solve Einstein's field equations for quark and strange quark matter in spherical symmetric space-times. We analyze strange quark matter for the different equations of state (EOS) in the spherical symmetric space-times,thus we are able to obtain the space-time geometries of quark and strange quark matter. Also,we discuss the features of the obtained solutions. The obtained solutions are consistent with the results of Brookhaven Laboratory,i.e. the quark-gluon plasma has a vanishing shear (i.e. quark-gluon plasma is perfect).

For this purpose, we solveEinstein's field equations for quark and strange quark matter in spherical symmetricspace-times. We analyze strange quark matter for the different equations of state (EOS) inthe spherical symmetric space-times, thus we are able to obtain the space-time geometriesof quark and strange quark matter. Also, we discuss die features of the obtainedsolutions. The obtained solutions are consistent with the results of BrookhavenLaboratory, i.e. the quark-gluon plasma has a vanishing shear (i.e. quark-gluon plasma isperfect). |
