Based on the characterization of GO and rGO materials, the electromagnetic parameters of the two materials are tested by the coaxial ring method, and their electromagnetic wave absorbing performance is analyzed in detail.
Therefore, graphene is one of the most promising new materials in the 21st century[1, 2].
Graphene is widely used to prepare substrate materials for composite absorbing materials because of its unique two-dimensional lamellar structure and the large number of active sites distributed on the surface.
The positions of the D peak and the G peak of the two materials are similar.
This has laid a solid foundation for future research on graphene-based composite absorbing materials.

A Fast Subdividing Circuit Design for Moire Frenge Grating with Smart Materials and Structures Nuan Song1, a, Yi Wu2,b , Wei Quan3,c , Wei Zheng4,d 1,2,3Air Force Aviation University, ChangChun,China abluebirdsong@163.com Keywords: CPLD grating sensor subdivision technolgy ,smart materials and structure Abstract.
In addition, we have introduction of the exterior synchronous clock .The technology not only overcome the instable situation but also improve anti-jamming of circuit system .It has been proved that the method get the better effort in practice. Ⅰ Introduction Along with the development of science and technology, all kinds of precision detection techniques of precision also put forward higher request.

Ultrafine Glass Fiber Core Material Produced by Wet method Tengzhou Xu1,a, Zhaofeng Chen1,b, Jieming Zhou2,c, Xueyu Cheng2,d, Wangping Wu1,e, Zhou Chen1,f 1College of Material Science and technology, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, P.R.
In general, the core materials have fibers, powders and foams [2].
Moreover, volume weight (about 150kg/m3) of the ultrafine glass fiber core materials is smaller than that of conventional insulation core materials, such as fumed silica, precipitated silica and so on.
Therefore, molecular collision doesn’t occur in the interior of core materials.

Meanwhile, green hotel should reduce purchasing disposable goods, try to purchase large packaging goods; and should purchase green raw materials, select safe, pollution-free green food raw materials.
The building and decoration materials of guest rooms should be “green decoration material,” or “ecological decoration material” with no pollution, and low energy consumption; therefore, it should avoid using plastic board or wallpaper that may cause allergic reaction, instead of that, it can choose unprocessed wood, bamboo, and rattan products.
The process includes three aspects: the production of food raw materials must conform to the green standards; the channel of food raw materials must comply with green standards; and the production process must comply with green standards.
