英文摘要	We study the thermodynamic properties of the Friedmann-Robertson-Walker (FRW) universe in the brane world scenario, concentrating on the Randall-Sundrum II model. From the first law of thermodynamics for the FRW universe, we find that the work density W can be identified with the thermodynamic pressure P. We construct the equation of state P = P(V, T ) for the FRW universe in the brane world scenario, which does not show P-V phase transition. We further study the Joule-Thompson expansion of the FRW universe, and derive the Joule-Thompson coefficient, which has an inversion point that is affected by the brane tension. These results could provide new ways to test the brane world scenario and extra dimension. (c) 2023 The Author(s). Published by Elsevier B.V.
