摘要

The definition of temperature in Chap. 1 arose out of a need to understand some basic thermodynamics. If a system has the possibility to exchange energy with a heat bath, the Boltzmann factorBoltzmann factor will be the weight that expresses the decrease in the number of available states for the heat bath when some energy is transferred out of it and into the smaller system. In this chapter we will apply this definition to a small microcanonical system, i.e. without contact with an external heat bath.
