ABSTRACT

Entropy is a special parameter in thermodynamics and statistical physics, which was proposed by German famous physicist Clausius in 1865. As a state variable, the change of entropy was related to the dispersion of matter (Shannon 1948), and the macroscopic significance indicates the uniform degree of the energy distribution of the system. In an isolated system, the occurrence of any irreversible process will lead entropy rising. At present, for non-reversible process, it always goes along a single direction of entropy increasing and eventually reaches equilibrium while entropy reaches maximum (Li 1986 & Tang 2004).
