A new procedure of polycrystalline synthesis and single crystal growth on AgGaSe 2 —— melt temperature oscillation and descending crucible with rotation method was reported in this paper.

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.
