Abstract

Firstly, we calculate quantitatively decrease of entropy by the known formulas in the ordering phenomena and nucleation of thermodynamics of microstructure. They show again that a necessary condition of decrease of entropy in isolated system is existence of internal interactions. Further, sufficient and necessary condition of decrease of entropy is also discussed quantitatively. Then some possible decreases of entropy are researched. A complete symmetrical structure on change of entropy is obtained. The analysis for many experiments and theories shows that the second law of the thermodynamics should be developed.
