Application of Value Engineering to the Ductility Design of RC Frame Columns with High Compression Ratio Guo Junqing 1, a, Fu Zhoucan 2,b 1School of Civil Engineering, Chang’an University, Xi’an, Shanxi, 710064, China 2Xiamen Torch Group Corporation Ltd., Xiamen, Fujian, 365001, China aguojunq101@sohu.com, bfuzhoucan20@163.com Key words: Value Engineering, High Compression Ratio, Concrete Frame Column, Ductility, Longitudinal Reinforcement, Tie.
The principles of value engineering were adopted to analyze the major factors affecting the ductility of reinforced concrete frame columns.
Their importance can be evaluated by using 04 grading method in value engineering.
It is known from [4] that the direct cost of a reinforced concrete frame columns consists of materials, labor and equipment, and the material cost is much higher than the sum of the latter two so that the cost analysis of a reinforced concrete frame column can be simplified as the analysis of its material cost.

Introduction The advantages of ceramics over other materials include high hardness and strength, chemical stability, attractive high temperature wear resistance and low density [1].
However, engineering ceramics materials are hard and brittle, and easy to form cracks, collapses, and other features during the machining process.

Thus，the gap between polysilicon and monocrystalline silicon has been continuously narrowed. 1.1 Production Engineering of Polysilicon At present, an improved Siemens technology is being used in polysilicon production in China.
(3) Shortage of Silicon Raw Materials in Polycrystalline Silicon-photovoltaic Industry China can't extract a large number of high purity silicon.
Owing to being constrained by raw materials, polycrystalline silicon-photovoltaic industry has to import more than 90% of silicon raw materials.
The process realizes one-stop production with processing of raw materials, production and the utilization of waste, making the production of polysilicon turning into informatization.

Research and Characterization of an Absorber Layer Material ---Cu(In,Ga)Se2 Sputtered on Polyimide Substrate in Material Engineering Yongping Zhao1, a, Congchun Zhang1,b, Guifu Ding1,c and Yongliang Wang1,d 1 National Key Laboratory of Science and Technology on Micro/Nano Fabrication Technology, Research Institute of Micro/Nano Science and Technology, Shanghai Jiao Tong University, 200240,Shanghai, China azyp2010sjtu@hotmail.com,bzhcc@sjtu.edu.cn(corresponding author), cgfding@sjtu.edu.cn, dwyl5617005@163.com Keywords: polyimide; Cu(In,Ga)Se2; solar cell; electric resistivity.
Cu(In,Ga)Se2 is a very important type of absorber layer material for high efficiency solar cells in material engineering.
In all the deposition method, such as co-evaporation, selenization, co-sputtering, electro chemical deposition and screen printing method, co-evaporation and selenization method can get the better quality of CIGS thin film among them, but when the CIGS film growth temperature is blow 400 ℃, the three-stage is inefficient for solar cells[8].RF magnetron sputtering is a commonly used method for the preparation of thin film materials, it is simple and easy to manipulate.
By heating substrate can increase adhesion between the film and substrate, promote CIGS grain to grow up, Sputtering pressure increased and sputtering temperature rose can cause the resistivity increasing. the film adhesion decreased with decrease of air pressure, appropriate Ar pressure is important, which is significant to make high efficiency solar film cells in material engineering.
