On the Influence of Heat Leak to Ecological Criterion of Refrigerators;

The optimal relation between the ecological criterion and the coefficient of performance, the maximum ecological criterion and the corresponding coeffici.

This paper investigates an irreversible absorption heat transformer for the optimization by taking an ecological criterion, which can make the best compromise between the rate of heat pumping and its dissipation of the cycle, as the objective function.

On the basis of an energy-analysis viewpoint established were the ecological criteria reflecting the optimal compromise between four-heat-source absorption heat-pump heating load and entropy production rate.

With an objective being the ecological criteria which enables the cycle heat supply rate and heat supply rate dissipation attain an optimum compromise the paper presents the study results of the optimization of a high temperature absorption heat pump.

Expounded further was the major significance of the ecological optimization criteria.

The elementary discussion of the ecology principles in urban park green space plan;

Although the theory is imperfect and is developing,ecology principle has the certain model function to our country socialism harmonious society's construction.

Through illustration and comparison on the life and social ecological principle and educational ecological principle, we can see that nature, society and educational syst.

Finally he developes the attitude maxim.
