主　　题：Joule-Thomson expansion black hole perfect fluid dark matter 

摘      要：In this paper,we study the Joule–Thomson expansion for RN-AdS black holes immersed in perfect fluid dark *** perfect fluid dark matter is one of the dark matter candidates,we are interested in how it influences the thermodynamic properties of black ***,the negative cosmological constant could be interpreted as thermodynamic pressure and its conjugate quantity as the thermodynamic volume,which give us more physical insights into the black ***,we derive the thermodynamic definitions and study the critical behaviour of the black ***,the explicit expression of Joule–Thomson coefficient is obtained from the basic formulas of the pressure,the volume,the entropy and the ***,we obtain the inversion curves in terms of charge Q and parameterλ.Furthermore,we analyse the isenthalpic curve in T–P graph with the cooling–heating region determined by the inversion *** last,we derive the ratio of minimum inversion temperature to critical temperature and compare the result with that in the RN-AdS case.
