The successive materials arriving to the substrate solidify on a surface at lower temperature that raises with the coating growth which slight decrease the cooling velocity of splats.
And hence, it is expected that graded layers might suppress the development of steep mismatch in properties at the interface of dissimilar materials, leading to a lower residual stress at interface.

Introduction Triaxial compound drive is shown interest at home and abroad for it`s large range of reducing interfacial tension and good outcome of increasing oil production.In applying triaxial compound drive,problems like scale formation in the oil production system and emulsified produced fluid caused by alkali are attracting focus from petroleum science and technology workers[1-2].Gemini surfactants are newly developed alkali-free surfactants.The technology is being positively researched and applied,for it has higher surface activity.It remains stable to product remaining oil and irreducible oil even in circumstances of high temperature and saltness[3].

ZnO is a wide band gap semiconductor with a high excite binding energy at room temperature and has attracted much attention because of its potential applications in gas sensor, photocatalyst, solar cells, ultraviolet light emitting materials, field effect transistors and flat panel players [3].
As the most potential TCO materials, ZnO films have been prepared by various methods including electrochemical route, chemical vapor deposition, hydrothermal process and physical vapor deposition [4-7].
