摘要：
The mechanical property of the thermal-equilibrium Friedmann–Robertson–Walker(TEFRW) universe is first studied.The equation of state and the scale factor of the TEFRW universe take the forms of w = w(a; zT) and a = a(a;zT, H0). For the universe consisting of the nonrelativistic matter and the dark energy, the behavior of the dark energy depends on the value of the present-day matter fraction. For the TEFRW universe consisting of N ingredients, the effective temperature is introduced. Lastly, a simple TEFRW universe model is analyzed.
