Furthermore, despite the using of single-component polymers, such as epoxide resin and polyvinylidene fluoride (PVDF) as matrix, we select IPN, one kind of polymer with unique network structures and with many potential applications in future, as matrix to study the dielectric properties of 1-3 composites.

Introduction Aspheric optical parts have advantages of correcting the aberration, enlarging the field of view, improving image quality and increasing operating range, and less aspheric mirrors can supersede more spherical mirrors, which help to simplify structure of the optical system [1,2].
UMC finishing technology is a new optical parts processing method which combines acoustics, electromagnetics, fluid dynamics and analytical chemistry [6].

It is obvious that can shorten the product developing cycle and save the material. 2 Establishing the basic equation model 2.1 Mass conservation equation ρm is the density of component m, the total density of the fluid ρ can get by next type: ρ= (1) The continuous equation of component m is: (2) Where：D is the quality of the components diffusion coefficient; U is the velocity vector; 、 is the chemistry and spray from the source term respectively; is the Crowe symbol（m=1, =1; m≠1, =0）. 2.2 Momentum conservation equation The momentum conservation equation of fluid mixture is: (3) Where：p is gas pressure, Mpa;A0=0 in laminar model, A0=1 in turbulence model; a is the dimensionless number, which is used in the Pressure Gradient Scaling method; k is the turbulence pulse kinetic energy, KJ/m3; g is the unit volume force volume force, which is
constant; σ is the surface tension, N/m. 2.3 Energy conservation equation The energy conservation equation (Internal Energy Equation) is: (4) Where: I is the internal energy removed the chemical energy, KJ/Kg; J is the heat flux vector which is the sum of heat transfer and enthalpy diffusion; T is the fluid temperature; is the enthalpy for components m; K is the heat conduction coefficient; ε is the turbulent kinetic energy dissipation speed. 3 Establishing the geometry and grid model The physical model is a kind of type Combustion Chamber in the Cylinder of Diesel Engine, more than 1 mm high combustion chamber clearance, the main structure parameters as shown in fig.1.

The corresponding selected area electron diffraction (SAED) pattern (Fig.3(b)) suggests that the ZnO nanorods have a single-crystal structure.

Influences of different calcinations ambience on Phase Composition and Morphologies of Ceramic Coatings on Ti Alloy by Micro-arc Oxidation Guodong Hao 1, 2, a Naiwu Zhang 1 Tao Yun 1 Jin Wang 1 Bo Lian 1 Wei Zheng 1 Weiguang Dong 1 Yujing Liu 1 1 Department of Chemistry, Mudanjiang Normal College, Mudanjiang 157012, PRC 2 heilongjiang province key laboratory of superhard materials a haoguodong163@163.com Keywords: Micro-arc Oxidation, Ti-6Al-4V, Argon, High Temperature Oxidation Abstract.
The aim of the work was first the ceramic coatings were prepared on the surface Ti-6Al-4V alloy by micro-arc oxidation, then the more compact structure and refinement ceramic coatings with the crystalline phase of a-Al2O3 were prepared in argon, which enhances the high temperature oxidation resistance properties of Ti alloys, and the influences of calcination ambiences on phase composition, morphology and analyses of the elements were also discussed.

The high levels of moisture, which are intimately combined in the coal structure, cannot be simply removed by drying as the product coal is unstable and tends to spontaneously combust.
