Recent years, the science and technology develop fast and the update speed of electronic product accelerates.
One is to test and maintain the electronic waste; put the product could be used into the second-hand market directly and send the materials couldn’t be used directly to the disposal factory to be crushed, selected, purified, etc.
The products and parts could be used still after testing and maintaining would be put into the second-hand market directly, and those couldn’t be used would be put into the second-hand material market to realize recycling if they can be recycled and utilized directly after disassembly.

As vascular stent has complexity in geometrical, more accuracy analysis results can be achieved when cylindrical lattice shell is considered as an orthogonally anisotropic material by homogenization.
From these parameters, the proposed formula can be proven to well follow the orthogonally anisotropic material relation equation zz z EE     [6].

Students can choose courses they are interested in and download online materials while learning; view their selected courses, participate in group discussions and take up online tests that are classified according to their levels.
This system is aiming at compulsory education, adult education, and science education.
The designers combine all kinds of multimedia materials to form an interactive, flexible, and audio-visual course.
Designers develop their own curriculum frame through a hierarchical structure, so learners can get a very good sense of directions in front of a large number of electronic reading materials without confusion.

Introduction It is well known that grain boundaries (GB) often determine the properties of polycrystalline materials.
In this case stress-to rupture value can be ten times lower in comparison with the same materials in inert atmosphere or vacuum.
