【Abstract】 The correspondence relationship between two-dimensional black holes and one-dimensional fluid is studied in this paper. The expression of acoustic metric is derived according to the hydromechanics equations,and we obtain some exact black hole solutions in two-dimensional dilaton gravity model. Moreover,the energy density ρ,speed ν and drive potential f in one-dimension fluid are calculated and the physical properties of these fluid parameters are also analyzed and discussed.更多还原
