Abstract: With the increasingly development and practice of interior design in China, designers are facing an important problem which requires them to have a good consideration,that is the culture reflected in their design is borderless.The urgent problem which comes to us now is try to reflect the inheritance and innovation of native culture in the interior design in a right way. Designers need to think better of returning to traditional Chinese culture and have it carried forward.The traditional culture and the taste of traditional aesthetic concept are well worth learning by designers, which is the foundation of the design. We should think deeply of current design behavior and face the reasonable direction of the development squarely, so as to make Chinese interior design more competitive in the world market.

Abstract: As house prices are soaring at present, small-sized apartments have become more and more popular among people. Low price and high yield are foremost concerns for all people when they purchase houses. Nonetheless, it is rather difficult to bring the functions of the little room into full play. Aiming at consumers’ demands, the author analyzes the space, lighting, furniture, color and adornments, proposing solutions to relevant problems regarding these aspects, for the purpose of utilizing little room with high efficiency.

Abstract: This paper summarizes the diffusion mechanism and relevant research method of oxygen which is diffused from courtyard greenbelt with the action of wind. This paper dynamically simulates the oxygen condition of courtyard space by the method of CFD. According to the simulation results, researchers make triaxial quantitative analysis for greenbelt distribution, oxygen diffusion and concentration distribution of courtyard space. Finally, this paper summarizes the basic law of oxygen diffusion influenced by greenbelt distribution of courtyard and puts forward some design strategies of greenbelt which is in favor of oxygen diffusion and oxygen environment of courtyard.

Abstract: This paper discusses the suitable working fluid applying in small diameter (millimeter scale) gravity heat pipe theoretically. The working temperature, characteristics of material, heat transfer limit and thermal physical properties of working medium of the heat pipe were studied. It is concluded that each aspect capability of heat transfer of R717 is excellent, but its working pressure is a bit high; the synthesized capability of R134a is relatively ideal and can be chosen as the working medium.

Abstract: To study the thermal environment of the greenway in Guangzhou, a field measurement was taken and a series parameters were measured such as air temperature, relative humidity (RH), the surface temperature of the underlying and the WBGT. The measurement studied the effect of grass, shrub, arbor and water to the different underlying pattern which were water permeable brick (WP brick), cement, asphalt and tile and discussed the design methods of the greenway thermal environment.

Abstract: We declare the intensity of solar radiation, UV strength, inside temperature, humidity, illumination intensity, IAQ field measurements for traditional houses and apartment house in order to evaluate their levels in the living environment in Sunan Yugur Autonomous County of Zhangye City, Gansu Province, China. This study has been conducted together with Professor Jiaping Liu, Xi’an University of Architecture and Technology. We have directed at the climatic and residential environments and local residents of western China. It is founded on Japan-China joint research, built on physical measurements and questionnaire surveys that enable healthy and sustainable development, on the basis of assessment of the climate and environmental characteristics of western China. Additionally, the project aims at proposing convenient methods to protect people against the adverse health effects of climate change, looking at inhabitants. Focusing our attention on the state of housing in rural parts of Sunan County and on the characteristic abundance of natural energy resources, we set out to develop a new model for energy-efficient housing adapted to available natural energy sources. We are aiming to reduce household energy consumption and to promote greater environmental conservation.

Abstract: In this paper, manganite (γ-MnOOH) nanowires have been synthesized, using KMnO₄ and CTAB as raw materials, by a hydrothermal method at 180°C for 12h. The samples were characterized by X-ray powder diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), scanning electron microscope (SEM),and thermogravimetric analysis (TG) for the information of crystal form, size, d-spacings, morphology and the weight-loss course. The results showed the manganite nanowires diameter range from 15 nm to 150 nm,length range from 5μm to 20 μm. Moreover, the properties of manganite (γ-MnOOH) nanowires as anode materials for Li-ion batteries had been studied. The first-discharge capacity is 1660 mAh g^-1 and corresponds to a consumption of about 5.5 moles of Li per mole of MnOOH, which made this material maybe one of the candidates for the negative materials.

Abstract: This paper focuses on the characteristic study of polymer matrix composites using a statistical approach, in terms of difference experimental and reflected to difference stacking sequence and orientation of composite lamination. Composite material, have an excellent characteristic and behavior, but with a difference application and materials used, it have a difference phenomenon occurred before the composite structure are collapsed. Therefore, in order to understand the characteristic of polymer matrix composites, it needs to investigate the phenomenon that influences the structure of composite lamination before failures. In this research, polymer matrix composites are produced using difference material and stacking sequence of lamination. The matrix used is thermoset epoxy and polyester resin with chopped strand mat (CSM) and woven roving (WR) as reinforcement materials. It has been produced using hand lay-up technique. The experimental work is carried out using the tension and flexural test accordance to ASTM-D3039 and D-D790 standard. By using a statistical approach, it can clearly show the differential between materials used with a characteristic of composite materials. It is noted, based on this investigation it also showed difference phenomenon failures and damage structure of polymer matrix composites with difference type of experimental.

Abstract: This is a study about using cerium ions solution to modify lithium silica fume and the phosphorus adsorption by the modified material. The way to modify lithium silica fume and adsorption conditions has been researched. It was found that capacity of adsorption have been improved after modification by the cerium nitrate. In the adsorption test, we studied the effects of the concentration of cerium ions, the calcination temperature, the dosage, initial pH value, reaction temperature and other factors on the adsorption. The results indicated that after modifications by 3% cerium ions , calcinations at 573k, the adsorption of phosphorus can get more than 90% when modified lithium silica fume dosage is 9.6g.l^-1 and the concentration of phosphorus solution is 4 mg.l^-1. In addition, the Freundlich adsorption isotherm is fit for the description of the phosphorus adsorption. The phosphorus adsorption process was in accord with pseudo-second-order kinetic model.

Abstract: adsorption is a good method to remove phosphorus. In the experiment, lithium silica fume is used as the adsorption material, adsorption isotherms ,kinetics and dosage effects were examined. It shows that the adsorption kinetics data are consistent with the pseudo-second-order equation and the adsorption is easy to happen. Freundlich isotherm equation is fit for description of the adsorption. The maximum adsorption capacities on lithium silica fume is 1.166 mg/g. When dosage get to 12 g/l and the concentration of phosphorus solution is 2 mg/l, the removal rate reach to 95% at 308k.
