W.G.Wang[9] simulated actual fibre orientation of composite structure by using of the fiber orientation model and provided theoretical foundation for ply cutting and splicing.
JL-237A type epoxy resin and JL-237B type modified amine curing agent produced by Changshu Jiafa Chemistry Co., Ltd, were used for matrix.

Effect of High-Calcium Fly Ash on Activity Index and Hydration Process of Phosphorous Slag Powders Caiyu LI1,a, Lin YANG1,b*, Jianxin CAO 1,c, Qiumei LIU 2,d 1School of Chemistry and Chemical Engineering, Guizhou University, Guizhou, 550025, China 2School of Civil Engineering, Guizhou Institute of Technology, Guizhou, 550005, China alicaiyude@qq.com, bce.lyang@gzu.edu.cn (Corresponding author), cjxcao@gzu.edu.cn, dlqm7777@qq.com Keywords: Phosphorous slag powders, High-calcium fly ash, Activity index, Hydration Abstract.
The granulated phosphorous slag is cooled using high pressure water quench, so that it contains more than 90 wt % vitreous structure, and possesses the potential hydration activity to some extent [2,3].

The major flavonols, kaempferol and quercetin, are different in a number of hydroxyl group on the B ring of their structure [6, 7].

Electrochemical Properties of Perovskite Cathode for Solid Oxide Fuel Cell Go Hiramatsu 1,a, Yoshihiro Hirata 1,b , Soichiro Sameshima1,c and Naoki Matsunaga2,d 1 Department of Advanced Nanostructured Materials Science and Technology Kagoshima University, 1-21-40 Korimoto, Kagoshima 890-0065, Japan 2 Department of Applied Chemistry and Chemical Engineering Kagoshima University, 1-21-40 Korimoto, Kagoshima 890-0065, Japan a g-hiramatu@apc.kagoshima-u.ac.jp, bhirata@apc.kagoshima-u.ac.jp, csamesima@apc.kagoshima-u.ac.jp, dn-matsunaga@apc.kagoshima-u.ac.jp Key words: Solid oxide fuel cells, Cathode materials, Electrochemical properties Abstract Gd-doped ceria electrolyte (Ce0.8Gd0.2O1.9, GDC, 700 µm thick), 30 vol% Ni-GDC cermet anode and perovskite cathode La0.6Sr0.4CoO3 (LSC) or La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) were used to evaluate the electric power of the cell using 3 vol%-H2O containing H2 fuel at 873 and 1073 K.
The above result indicated that the replacement of Co by Fe in the B sites of perovskite structure enhances the formation of oxide ions.

According to the surface physical chemistry theory, oil has different wetting actions on different solid surfaces.
Because the inner of foam is the structure like grid or film, it not only has a large surface area, but also contains rich capillary channels. [6] The Impact on Performance Due to the Different Times Treated on the Polyurethane Foam which is Dealtwith Tung Oil.

Consequently, multifunctional materials requiring a specific combination for a certain application can be obtained by only a slight variation of the molecular structure or chemical composition in such a polymer system [7-9].

In this work, it is hoped to make the originations and structure difference of obtuse triangular clear by confocal microscope and room photoluminescence image system installed in SICA88.
Experimentals 4 inch 4H-SiC homo-epitaxial layers were grown with a hot-wall reactor Aixtron VP508GFR on commercially available 4 inch 4° off 4H-SiC substrates. 4H-SiC layers were grown on the Si-terminated face in H2-SiH4-C3H8-HCl chemistry.
