vapor transporting method with two-zone temperature oscillation, and generic vapor transporting method respectively.

Through illustrating the principle of the thermal fatigue crack in the surface of machine parts, and using the wave spreading theory, the paper focuses on the temperature oscillation in the wall of Combustion Chamber of diesel engine and the effects of the alternating thermal stress on the surface of machine parts, and then puts forward how to decrease the destructive effects.

A solution of its temperature oscillation has been got for the purpose of the heating design.

Using geotemperature and weather data by continued 4 years observation after the chinese Great Wall Station was built,the authors studied the geotemperature oscillation characteristics at different depth and time scale in active layer on the Antarctic Fildes Peninsula by analyses of time succession linear and compromise relation.

Experimental and Numerical Investigation of Oscillating Water Column Wave Energy Convertor;

The caisson structure of breakwaters has been widely used, the onshore Oscillating Water Column (OWC) structures for electricity generation ,on the other hand, is one of the most promising type in the wave energy conversions.
