A Study on Entropy Theory in Physics and Its Application
Zhang Dong · Journal of Beijing Union University · 2007
Entropy is an important concept in physics.The entropy theory is analyzed and discussed.Based on the definition and basic properties of entropy,the derivation of three entropies is discussed.The concept of negative entropy and its significance in open system is studied.The entropy theory is applied to the analysis of the quality of energy.It is pointed out that energy of high entropy value is low quality and the energy of low entropy value is high quality.With the negative entropy theory,the motion rule of life is analyzed,and the existence of negative entropy as a necessary condition for normal life maintenance is pointed out.
