MRPII integrates human resources, equipment and raw materials requirements into the overall financial and cash flow management.
In a situation where effective capacity is less than the required capacity, the enterprise avoids implementing the material plans until a realistic schedule is made which prevents waste of raw materials.

Preparation of Delithiated Cathode Materials of Li-ion Battery by Chemical Extraction Employing Na2S2O8 Shijian Yan1, a, Mingang Zhang1, Yuesheng Chai1, Wenhuai Tian2 1School of Materials Science and Engineering, Taiyuan University of Science and Technology, Taiyuan 030024, China 2Department of Materials Physics and Chemistry, University of Science and Technology Beijing, Beijing 100083, China ashijianyan@sina.com.cn Keywords: chemical extraction; delithiated cathode materials; Li-ion battery Abstract.
A method of conventional chemical reaction to prepare delithiated cathode materials of Li-ion battery has been introduced.
A series of tests were conducted to verify the composition, crystal structure and electrochemical property of the delithiated cathode materials were all desirable.
Delithiated cathode materials with various lithium contents are needed in order to analysis the microstructure and properties.
Journal of Wuhan University of Technology-Mater.

This material has several advantages over other cathode materials such LiMn2O4, LiMnO2 or LiCoO2.
Compared to these cathode materials, LiFePO4 is more stable, more environmentally friendly and abundant [1,2].
The purpose of this step is to decompose the organic compound contained in the starting materials.

Experiment Materials and Procedures Materials and Properties.
As a result, the steel surface materials were worn down.
Therefore, the wear mode of the steel surface materials may be changed.
The effect of water on the tribological properties of materials is complicated.
For example, in some cases, the existence of water may act as lubrication and reduce the friction coefficients and wear rates of materials, but it can also produce corrosion and oxygenation, and then aggravates the wear of materials [12].

Introduction Functionally graded materials (FGM) have widely used as structural components in aerospace, automotive engineering [1].
Therefore, structures where a substrate made of FGM is coupled with surface-bonded piezoelectric layers and using piezoelectric materials to realize structure vibration control in the engineering department has a broad application prospect.
Material Properties Generally speaking, most of the FGM are employed in high-temperature environments and many of the constituent materials may possess temperature-dependent properties.

To develop constructive and ingenious solutions that increase the durability of these materials in time, it is necessary to know all the requests that these materials have fulfil.
The two materials were studied under an A.
This study showed that the material with a PU matrix has a much lower resistance to burst than the PVC matrix material, thus the PVC matrix materials should be preferred for high wear applications.

In many cases we can see, because of the application of new materials and technologies, athletes’ performance improved, such as a U.S. company for new materials and rapid skin swimsuit swimwear were strong research and development , this swimsuit can reduce drag in the water were a large extent, then swimming speed you can get a greater degree of increase.
If the one-sided emphasis on science, it will lead to the proliferation of science and technology in sports, affect the normal development of.
