Materials used in external breast prostheses.
Regarding the materials used in conventional external breast prostheses, silicone, cotton, and synthetic foams are among the most commonly identified
In response to the limitations of conventional materials, new alternatives have been explored for the fabrication of personalized external breast prostheses.

Grinding tool usually consists of two kinds of material, grain for removing workpiece material and binder for binding abrasive grains.
Matsuo and Okamura [1] used nine kinds of diamond and CBN abrasive grains to grind many kinds of hard brittle materials, such as sintered carbide and aluminum oxide.
It results in the increase of material protrusion in front of abrasive rain and relative decrease of material protrusion beside abrasive grain.

The conductive plastic is widely used in making sensitive materials such as angular displacement sensors with high-precision.
The latter is compounded by adding conductive fillers into polymer materials.
Based on a resistor with a diameter of 30mm and an initial resistance of 5k, ten samples are done for these two materials.

Introduction Cu-graphite composite material is a type of the most popular metal-graphite brush material.
With the development of science and technology, motor industry calls for better performed brush material, and the currently-used Cu-graphite composite material can no longer meet the requirement of the time.
I Material preparation and experiment methods 1.1 Preparation of composite materials The materials used in the experiment are as follows: a) carbon fibers, produced by Shanghai Carbon Works, the tensile strength of which is 2580MPa, density 1.77g/cm3, single wire diameter less than 7μm; b) conductive ceramic particles Ti3SiC2, produced by ceramic material research institute of Tsinghua University, which were prepared after 320 mesh; c) copper powder, produced by Beijing Youyan Powder Company, Ltd., which was electrolytic copper powder of 320 mesh; d) graphite powder, by Shandong Nanshu Graphite Mine, which was 300-mesh flake graphite powder.

To reduce planning costs and errors, directors decides to use the DF technology for planning assessment, including the facilities layout of workshop and the materials handling, they want to assess these in 3D virtual scene.
But the layout simulation can’t simulate the impact of dynamic factors in the materials handling; and the layout model has to be re-established in materials handling simulation analysis if considering the details of the layout.
To reduce the modeling workload, the layout model and materials handling model will be built in the DF platform, multi-level modeling will combine the two models and run it with multi-resolution simulation (Fig. 3).
Virtual reality simulation of the layout model can be used in the analysis of materials handling simulation.

Some houses had too high story height, which increased the heat loss in winter and wasted the materials, and the unreasonable energy structure, less use of clean energy and so on.
The reasons of poor indoor thermal environment In the medium of 1980, although the local villagers generally realized that the thermal insulation property of raw earth wall was far superior to that of brick wall, but the materials of wall of local houses changed from raw earth to solid clay brick with the rapidly development of building construction technology and new building materials along with the increasing of economical level and transforming Philosophy.The exterior brick wall didn’t take any heat insulation measures instead of bare brick wall, without finish materials protection, it is possible to increase the cold air infiltration and wall heat transfer in winter.
