Abstract: During breeding season, the diets of the Long-legged Buzzards (Buteo rufinus) were studied through pellet and prey remains analysis in arid habitat of northwestern China from 2005 to 2006. By number, mammals 60.00% constituted of the diet, birds 18.00%, reptiles 22.00%. In term of biomass, mammals comprised 87.19% of the diet, birds 6.18%, reptiles 6.63%. The most numerous prey of the Long-legged Buzzards was Rhombomys opimus (48.00%), but Gazella subgutturosa (57.97%) dominated the diet by biomass. Special findings included homing pigeon and a number of nestling and fledging Passerines in the diet. Our results showed that mammals and birds were major prey of breeding Long-legged Buzzard, and results suggest that this Buzzard is an opportunistic hunter and feeds on a wide range of food habitat.

Abstract: Solvent-free adhesive is a kind of environmental friendly adhesive which is safe, less material consumptive and just needs simple curing conditions. In this paper, the two components solvent-free polyurethane adhesive for flexible packaging was discussed, including its characteristics, composition, curing and adhesion mechanism and three modification methods. The curing mechanism of this adhesive is that crosslinking happens between –NCO and –OH which are contained in two components respectively. However, its adhesion mechanism is different when the adhesive is bonding with polyester film, paper, fabric, metal and other materials. The modification methods of two components solvent-free polyurethane adhesive include modification of its soft segment, modification with epoxy resin and modification with organosilicon and so on. The performance of adhesive can be improved through modification.

Abstract: Both the government and the firms are concerning about the development of cyclic economy for highway projects construction. However, the huge investment risks and technology spillover are primary obstacle for developing and research of energy saving and emission reduction. This paper introduces the theory of the dynamic game of complete information to analyze how the government provide sufficient subsidy and make preferential policy to promote the firms to do it for their own interests. According to the establishment of sub-game perfect Nash equilibrium under non-corporative conditions, it indicates clearly that the most effective measures to make sure the firms to develop cyclic economy is that the government should maintain the highest rate of subsidies to the first firm who is willing to developing the energy saving technology.

Abstract: Base on the theory of rainstorm and flood, concept of spatial image and geographical, the elementary and computing technique foundation of gis. In experimental plot data quite complete situation, Summary science reasonable, both accurate and highly effective rainstorm flood space and time structure evolution rule research technique, And key discussion and research spatial data pretreatment and quality analysis, space and time structure differentiation analysis, spatial reckoning analysis, spatial pattern analysis and spatial autocorrelation analysis in rainstorm flood space and time structure evolution research concrete application.

Abstract: Current research on the river ecosystem in Taiwan is a lack of integrated strategy on urban river ecosystem management. This study aims to evaluate the river quality based on eco-security. Our goal is to provide a framework to conceptualize the impacts of various urban river eco-security development. Using the systems thinking, the related eco-security operation mechanisms have been constructed by five subsystems, “drainage control” ,”purification ability”, “water recycled”, “habitat” and “biomass” analyzed. Also, through the new Fuzzy Delphi expert survey, the index system of urban river eco-security (IES) has been compiled in order to explore the variables. It is clear that urban river eco-security model provides an alternative decision model and corresponds to the direction of sustainable city.

Abstract: A simulation method was presented based on the theory analysis and ozone reaction equation. The preliminary mathematical models of ozonation correlative to oily pollutant removal were set up by numerical simulation. The ozonation models implied removal ratio of oil related to reaction time, ozone dosage and initial oil content. The simulation results were consistent with the experimental data.

Abstract: The wetland possesses very important environmental function and ecological benefits. Study on the Wetland Nature Reserve along the Yangtze River in Anqing has become a focus of academic community for its well nature. The resources and function of wetland along the Yangtze River in Anqing were analyzed and the dangers faced by the wetland from agricultural pollution, water conservancy, unreasonable fishery production, invasive species were discussed. In order to promote sustainable development of wetland resources and environment, the suggestions and policies about the protection for Anqing wetland resources and environment were proposed.

Abstract: The problem ofcontrol of Lurie time-delays switched systems is investigated. Lyapunov functions is used to derive the sufficient conditions for the systemsabsolutely stable

Abstract: The effect of relative height between the bottom of the tank and the top of the collector on performance has been studied both theoreticaly and experimentally. According to the national testing standard methods, the efficiency of the system was tested. The results show that the simulation results are in good accordance with the experimental ones. The data indicate that the optimum value of relative height is 0.74m with the maximum efficiency of 67.7% for the system with a total area of 1.5m² and storage water tank capacity of 120L. Increasing or decreasing the relative height within a range of 0.3m has no significant effect on thermal efficiency.

Abstract: Ash samples were collected using eight classifications of atmospheric particulate matter sampler in two temples located in Jiaozuo city. Concentration of particles of different grain size was measured and analyzed. The results indicated that particulate mass concentration was significantly increased in the burning incense air. The maximum concentration of PM_9.0 and PM_2.1 were 9 times than that of the national air quality secondary standard (PM_9.0:0.15mg/m³) and 13.5 times for American standard (PM_2.1:0.065mg/m³), respectively. The size distributions of particles from incense burning overall showed “U” model. Range of size distribution of fine particles concentrated in 1.1~0.43µm, or the total 39.36%~50.14%.
