Abstract: Mixed combustion of biomass and coal is a new combustion way of comprehensive utilization biomass and coal energy resources. Biomass is more volatile, lower combustion temperature, combustion is mainly concentrated in front, low calorific value and the use of value is limited. Coal is less volatile, high combustion temperature, combustion exothermic are mainly concentrated in coke combustion, and exothermic is high. Studying on the combustion process and the combustion characteristics of mixed combustion of biomass and coal is development technologies based of mixed combustion of biomass and coal. Choose two biomass sample Sawdust, confetti and a coal, analyze combustion characteristics to mixing sample of different ratio, to obtain combustion process of mixed sample, combustion performance impact of biomass to coal and calorific influence of coal to biomass.

Abstract: Cross-sectional TEM observation can be used as an important method in the microstructure investigation of thin films. However, the specimen preparation for cross-sectional TEM observation is generally regarded as a challenging task. In this paper, we discussed the preparation of TEM cross-sectional specimens. An example from GaN thin films grown on Si substrate was discussed correspondingly.

Abstract: In this research, these elements such as Cu, Fe, Al, Cd, Pb,Mn, Zn, Ti and As were measured by ICP-AES equipment, the elements derived from Dipsacus asper Wall. from different places such as Gesala county, Pingdi county, Puwei county,Ala county etc. Detection limits ranged 0.0020 ug/ml^-1 and 0.079ug/ml^-1, the relative standard deviations for all these elements were lower than 2%, and recovery rates ranged 94.5% and 107.2%. The results showed that there were many metal elements in Dipsacus asper Wall. from different location; contents of Fe and Al were highest in Panlian county’s sample specially; contents of Mn, Cu, Zn and Ti were moderately high inYumen county specially; and contents of As, Cd and Pb were lowest in Yongxing county. From the result we tested,It was differernt the contents of metallic element of all sample origined from differnt place.It’s relation to environment. so, environment supervise was important goal to achieve.

Abstract: In this work, the contents of all elements including Cu, Fe, Zn, Al, Mn, Cd, Pb, Ti and As were tested by ICP-AES technique, which elements root in Fallopia multiflora from different place such as Renhe county, Miyi county, Qianjiang county and so on. Detection limits ranged 0.0021ug/ml^-1 and 0.076ug/ml^-1, the relative standard deviations for all these elements were lower than 2%, and recovery rates ranged 95.52% and 107.2%. The consequence showed that there were many metallic elements in Fallopia multiflora from different places; contents of Fe and Al were highest in Renhe county’s sample specially; contents of Mn, Cu, Zn and Ti were moderately high in Yanbian county specially; and contents of As, Cd and Pb were lowest in Qianjiang county. concentrations of elements within Fallopia multiflora from different places were different, which may have some relations with the environment where Fallopia multiflora grew. So ,its necessary to monitor the environment condition of plant surronding.

Abstract: In this paper, the contents of these elements including Cu, Fe, Mn, Zn, Al, Cd, Pb, Ti and As were determined by ICP-AES technique, which elements originated from maca from different places. Detection limits ranged 0.0022 ug/ml^-1 and 0.077ug/ml^-1, the relative standard deviations for all these elements were lower than 2%, and recovery rates ranged 95.56% and 106.2%. The results showed that there were rich metal elements in maca from different places; contents of Fe and Al were highest; contents of Mn, Zn, Cu and Ti were moderately high, and contents of As, Cd and Pb were lowest. Futhermore, Cu, Fe, Mn, Zn were essential to people’s health, and Al, Cd, As, Pb and Ti had potentially physiologically toxic. Finally, concentrations of elements within maca from different places were different, which may have some relations with the environment where maca grew. As a result, the determining method which elements of maca. are determined by ICP-AES is rapid, accurate and convenient, and wild maca may contain toxic elements because of pollutional soil and environment, so maca cultivated artificially can effectively reduce harmful elements.

Abstract: We take “5.12 Wenchuan earthquake” influence and one of the university in Mianyang urban area as the typical examples of the disaster preparedness community. We discuss how to plan the multiply disaster preparedness which in accordance to the geographical feature of hilly cities through the material properties of engineering materials research and study of the four-dimensional space disaster preparedness model.

Abstract: After the WenChuan earthquake in may 12,2008,Many province government built the temporary houses for earthquake disaster area.For the first time, they initiate such large scale project, there are many problems emerged during the process of construction such problem like economy ,environment, engineering materials and technology. In this article, we collect problems and analysis them ,seek for the possible measures of construct the temporary house and the effective way to rebuilt the disaster area.

Abstract: As a sports apparel clothing categories overall, in the broadest sense can be divided into professional sports apparel, sports everyday wear and sports accessories three categories. Professional sports apparel mainly athletes to participate in various sports competitions at the time of wearing apparel, the sport has its own characteristics, in order to adapt to the development of sports, professional sports apparel in the production process, new technologies, new processes, new fabrics should continue to appear, in order to make professional sportswear meet the requirements. Casual sports tend to be fashionable, but it retains the unique features part of sportswear. Sports accessories mainly involved in a number of areas of protective equipment and the use of equipment. The new thermal wicking fabrics, including fabrics, super-elastic fabric, waterproof and breathable fabrics, three-dimensional fabric composites, carbon fiber materials. These new materials for professional sports clothing, casual sportswear and sports equipment and sports goggles have a positive and practical impact. This paper studies the application of new fabrics in professional sports apparel, casual sportswear and sports protective appliances.

Abstract: In this study, Al₂O₃–13 wt% TiO₂ ceramic coating was prepared on the substrate of a GH416 Ni-base superalloy by squash presetting laser cladding. The effects of processing parameters on dilution ratio were investigated. The result shows that the coating consists of two zones: the ceramic clad zone and dilution zone. The dilution ratio increases with the increase of laser power, whereas, the dilution ratio decreases with the increase of laser beam moving velocity. However, the coating with a low laser power is difficult to obtain metallurgical bonding to substrate, and with a high moving velocity can easily produce pores. The clad ceramic coatings characterized by a dense structure, no cracks, low dilution, and good metallurgical bonding to substrate were obtained under optimum processing parameters.
