Taking three production modes for example, the entropy increase quantity is calculated by using the model and the environmental effect trends can be educed.

This paper briefly introduces entropy s microcosmic notion and expounds that entropy increase results in energy devaluation.

Focusing in the irreversible gain of entropy resulting from temperature difference between non-azeotropic refrigerant mixtures and the cooled water,the paper constructed steady heat transferring model of mixed working fluids and the chilled water.

Focusing on the irreversible gain of entropy resulting from temperature difference between non-azeotropic refrigerant mixtures and the cooled water,the steady heat transferring model between mixed working fluids and the cooled water has been constructed.

Taking a typical tech-venture recurring to venture capital as the case,and based on the theory of entropy increasing and dissipative structure,this paper analyzed the current situation of coordination in the mentioned ventures management via a model,summarized the existing problems for tech-ventures,and put forward some corresponding countermeasures against the existing problems.

The theory of entropy reveals that all things and processes as well as the development of human society are the dialectical unity of entropy increasing and entropy decreasing.

The livelong process of AD of MSW in terms of entropy was analyzed,and results indicated that in the pretreatment such as collecting,separating and material enhancement of AD,the collecting is a process of entropy increasing(PEI),the separating is a process of entropy decreasing(PED) and the enhancement of material is PED.
