The computational results show that flyer plates kinetic energy efficiency has direct ratio to laser pulse width and flyer plates diameter,whereas has inverse ratio to focus spot,power density and flyer plates thickness.

This paper introduces a kind of working principle of new vertical shaft wind turbine,and brings forward a calculate method of wind turbine in the form of efficiency of wind energy utilization according to the prototype of trefoil structure.

Comparison of energy utilization efficiency between China and foreign countries;

Analysis of a new index on the energy utilization efficiency based on the dual-structure;

In order to effectively improve the energy utilization efficiency,improve the current state of energy conservation work and promote the economic sustainable development in Sichuan province,based on the analysis of current energy saving status and relevant problems,eight supporting measures were proposed to promote the energy conservation work in Sichuan from the economic,policy,and legal prospect.

Study on the Dynamic Change of the International Energy Efficiency;

In pace with the new national industrialization development strategy put into effect as well as following the established target to reduce energy consumption on the basis of“the eleventh five planning”, the imminent problem facing scholars is how to promote research on energy efficiency effectively.
