Li Key Laboratory for Advanced Ceramics and Machining Technology of Ministry of Education Tianjin University, Tianjin, 300072, China Keywords: Grinding chatter suppression, Variable grinding condition method, Limited random feed method Abstract.
Moreover, it lays an important foreground to be applied in engineering for numeric control grinding.
The change of the grinding condition will cause the change of grinding forces and different elastic deformation of the grinding system, thus influencing the material removal rate.

So the event of a terrorist attack and pollutants through a complex air channel in the construction of the rapid proliferation of high concentration. 2.2.1 The signal detection while being attacked by CBR terrorism Timely finding CBR attacks, is the key to the built environment security.
In short, taking into account the terrorist attacks, the design and renovation of central air-conditioning systems should be pay attention to: (1) Increased filtration devices, especially medium-efficiency filter, all the devices installed the air purification materials such as activated carbon or high-fiber
The risks and effects of indirect, cover, terrorist, and extremist attacks with weapons of mass destruction [R]. 2001 [2] Committee on science and technology for countering terrorism of division on engineering and physical sciences of national research council.

Application of Wide Band Oxide Semiconductor in Bulk Heterojunction Solar Cells Jianmin Ye School of Mechanical and Automotive Engineering, Hubei University of Arts and Science, Xiangyang, 441053, P.
Recently, nickeloxide(NiO) thin film has attracted considerable attention because it can be used as a p-type transparent conducting film, an active electrode in electrochromic devices, and resistance change material in resistance random access memory(RRAM) devices [7].
It is known that as a p-type semiconductor material, the resistivity of nickel oxide film depends on the concentration of cation (Ni) vacancies.
But deadly factor of 4-8 nm thick NiO solar cells is fill factor (FF), they all have poor FF, larger leakage current and deficient electron blocking capability maybe the key factors.

In the rock cutting process, the mechanical system has highly nonlinear characteristics due to the anisotropic rock materials.
