Surface heat flux calculation of variable entropy flow for hypersonic blunt bodies;

In this paper we prove that the global existence theorems of the solutions to Cauchy problem for a class of quasilinear parapolic systems, by using of the entropy-entropy flux.

The enthalpy-entropy compensation was thermodynamically examined in the phase changes,chemical reactions and other analogous processes.

In this paper,entropy calculating formula was discussed by means of dissipative structure theory and applied the calculated formula to predict entropy changes of the town ecosystem of Dafeng and Xishan city in Jiangsu province,and the results met the fact we.

Research on entropy change model for enterprise system based on dissipative structure;

Research on entropy change for knowledge state system of knowledge-based enterprise;

The paper discusses the relation of entropy change and quotient of heat-temperature based on the second law of thermodynamics.

Consequently the direction of entropy flow .

The conditions forming dissipative structure in supply chain system are analyzed, the positivenegative entropy flow in supply chain system is analyzed and explained and finally a model of supply chain entropy flow is established.

In applying the theory of non-equilibrium thermodynamics to the detecting system,the computing formula of entropy flow is derived,and formulas of information transformation and delivery are given.
