In all-day long, the Fv/Fm, ΦPSH and ETR of C_3 plants were higher than that of C_4 plants notably, it was based on the high PS II activity and high efficiency of energy conversion and energy transmission.
On the basis of the aquatic ecosystem and Lindeman's "efficiency of energy conversion ", following formula is suggested to estimate the complex potential production of fish in the reservior. Fc=0.1 Λ_1-0.9f_2+10Λ_4 Thus, the complex potential fish production of the reservior is 253.08 kg·ha~(-1)~(-1).
The specific process and characteristics of the energy conversion by the water sail machine are explained. Bernoulli's equation is applied in the water sail machine and the basic formula N = 9.81 Qh has been derived,showing that the water sail machine still abides by the basic law of energy conversion in nature.

Power industry energy saving possesses the important position in the work of China's resource saving, the content of which is mainly to raise the energy conversion efficiency and reduce conversion loss, at the same time, energy saving and electricity saving in demand side also have important influence on power development.
The relative electron transport rate(ETR) was B>A>C, the efficiency of solar energy conversion(Fv/Fm) and potential activity(Fv/Fo) of the PS II in the leaves were different, which of the A was the highest.
Around the innovative ideal, the overall feature need of energy conversion device is brought forward. Then the gross structure is designed, which is mainly constituted by an air-driving-rotation component and a micro DC generator.
The efficiency of solar energy conversion and potential activity of the PSII in the leaves differ significantly, with the dentate broad-ovate leaves the highest.
The modern needs of structural integrity technology are largely attributed to the increase of service temperature of the structures that results in the efficiency improvement in energy conversion and chemical processing technologies.
Energy policy and its promotion of MSW-to-energy conversion are also elucidated.
