Abstract
A decoherence mechanism in the transition from pure quantum- mechanical systems to thermodynamical systems is proposed. We see that a quantum-mechanical expression of temperature is derived and the expression for boson systems and that for fermion systems are different. An application to the calculation of change of temperatures is investigated in a quasi-static process and numerical analyses for mixing of two gases with different temperatures are carried out. Considerations in terms of ultra-power representations of nonstandard-analysis are also presented.
