Figure 12: Product variance of heat dissipater As Figure 12 shows, different materials and sheet thicknesses can be processed.
Oehler [20] proposed these characteristics for several materials as seen in Figure 14. 1: Al99,5 w 2: St 1404 3: St 1203 4: CuZn 33 w Figure 14: Springback ratio K for several materials as a function of the bending radius [20] To integrate the displayed characteristics processable by the machine control (PLC), they are approximated by polynomials of 5th order.

Multi-dimensional Numerical Simulation of Emission Characteristics in DI Diesel Engine Wenming Cheng1,a, Gang Li2,b 1College of Science and Technology, Nanchang University, Nanchang, Jiangxi, 330029, China 2School of Mechanical and Electrical Engineering, East China Jiaotong University, Nanchang, Jiangxi, 330013, China aCheng_wenming@163.com, bligang0794@163.com Keywords: DI Diesel, Numerical Simulation, Combustion, Emission Characteristics.
In this paper, AVL FIRE software was used to three-dimension simulation analyze the combustion processes and the emission characteristics of DI diesel engine, which provide a theoretical basis and reference materials for the optimization of the fuel injection system design and reducing diesel emissions. 1) In the step of oil inject, most soot generates at the place where pocket of oil’s forward arrives and approaches the wall of firebox; when oil injection stops, the soot generated in the centeral heave above of combustion chamber is more.

The structure of beam frame is in a pithy style and comfortable proportions in materials.The height of beam frame is moderate and the structure of beam frame is in a good keep.
It’s difficult to find an historic building museum like this one, and DongYue Temple is not only a indispensable part of various architecture artistic forms of Jin Memorial Temple but also a high value of history, art, science and social culture.
It has become the educational base to study the Chinese traditional architecture and historic culture because of its abundant value for the history, art and the science.The protection of DongYue Temple is conducive to preserve our cultural heritage and continue the local cultural traditions, fully reflecting the inheritance and innovation from the different times.
