Analysis on Crack Propagation Mechanism of Nano-Single Crystal Copper about Holes Influence Ge Li, Ming Chen, Zhimin Liu Inner Mongolia University of Science and Technology, Baotou, 014010, China ligeab@imust.cn Keywords: Molecular dynamics, Holes, Crack propagation mechanism Abstract.
Introduction With the gradual deepening research of nano technology, the microscopic mechanism of the material crack initiation and propagation under nano-scale were urgently needed.
The crack propagation and fracture process of metal material were caused by the chemical bonds change of particles at the atomic scale, such as the formation of dislocation nucleation, motion, and empty, twins, micro-crack propagation [2, 3].
Therefore, it is very necessary that the influence of material internal defects such as the hole on crack propagation mechanism were researched.

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].
