This method uses approaches of elimination or breakdown of raw materials to yield desired materials characteristics [11].
Since structural parameters affect materials' behaviour, the study's results would favour our understanding of how material processing impacts applications.

And the parts which can not be used will be separated to materials by crushing processing.
For direct reuse of parts, the cost of materials is mainly used for cleaning of the auxiliary cleaning stage material.
For the renovation of the repair parts, the cost of materials are mainly used for remanufacturing and processing stages of repair parts auxiliary materials.

The Selection of Coating Material.
At the same time, the driver roll shaft turns driven by the motor to provide sufficient packaging material.
The specific operation process of coating machine as follows: Step 1: Before the machine starts working, agencies have pushed flush with the spring plate, feed mechanism automatically saved to a certain number of spring materials .Spring rolls automatically and falls on the access panel push-up device.

Experiment 2.1 Materials The industrial A356 aluminum alloy used in this work was obtained from a certain aluminum processing plant of Yunnan province, China.
As it can be seen from Fig.1 (a), the morphology of eutectic silicon phase is obviously different strip and acicular, and the sharp angle of acicular eutectic silicon has split the matrix material without stirring.

The AD and motor driver design Material spectral characteristics reflect the properties of the material itself and state, as material is different, its spectral characteristics are different.Various optical active substances in water absorb the radiation of light ,the characteristic as well as the scattering nature determines the spectral signature of water body.
Underground aquifer water, rich in all kinds of metal ions, compounds, such as different materials fluorescence, the fluorescence signal wavelength is different, so adopt the light signal at a certain moment is useful to determine the class of a chemical.
