Abstract: Sports information integrated management has become a future development direction as the scombination of the sports information integrated management and the information technology. In this article, the integrated management of sports information is analyzed. Sports information integrated management can be defined as comprehensive management of sports information resource and its exploitation and utilization activities. Its main elements include subject, object, information users and management tools. Its main contents are sports information demand analysis, sports information resource construction, sports information resource development and utilization and network sports information resource management. Based on this analysis, the authors have developed a set of school sports information integrated management application system based on network in order to make it more scientific and systematic.

Abstract: Wellbore system is the flow channel of the well fluid and the key link of pressure control. Along with more and more frequent accidents caused by the failure of well integrity in recent years, how to ensure well integrity in physics and function has become a research focus. Based on the analysis of the domestic and foreign papers about well integrity and well integrity management, this paper explained the concepts and histories related to well integrity, the dangerous consequences resulting from the failure of wellbore integrity and the reasons of the failure are analyzed selectively. Then, proposed the research direction of the wellbore integrity and the main problems that could be solved respectively.

Abstract: Human body is a complex life forms.A lot of complexity means that affect motor function of factor structure. Human movement is a dynamic feedback process control, need to be coordinated through the visual, vestibular, proprioceptive feedback, not only by the physical laws of gravity, inertia force of domination, but also by the emotional impact of individual factors such as hobbies. Computer modeling of human actions including key frame method, kinematics, dynamics, motion capture method and process control methods. These methods have their own advantages, there are also their limitations. The different methods to combine the use of their complementary strengths will be the focus of future research and development direction.

Abstract: With the depletion of mineral resources, more attention is paid on the secondary resources to recover valuable metals. In this paper, a research is carried out to recover copper and iron from copper smelting slag by flotation and magnetic separation. The influence of grinding fineness and collectors on flotation of copper are investigated. A copper concentrate is obtained by flotation and an iron concentrate is obtained by magnetic separation in the closed circuit flowsheet. The copper concentrate contains 18.86% Cu with a recovery of 72.36%, and the iron concentrate contains 52.24% Fe with a recovery of 70.87%.

Abstract: Acidophiles have been widely used in heap and dump bioleaching of secondary copper sulfide ores and biooxidation of refractory gold ores. 22 genera of acidophiles have been found in biomining environments. This paper gives a preliminary introduction to the application of mineral biomining in China. Challenges and technical trends for heap bioleaching of primary copper sulfide ores, purification of bioleaching solution of polymetallic sulfide ores and biooxidation of carbonaceous refractory gold ores are also recommended.

Abstract: In the past ten years, methane has a greenhouse gas, and its concentration increases by 1% per year, while an estimated worldwide annual landfill cover soil surface from escaping methane is about 20 to 70 Mtpa. Microbial methane oxidation can be carried out about 80% of global consumption of methane, the soil microbial methane oxidation can reduce methane escaping from the soil to the atmosphere. Both in domestic and foreign ash recycling in landfill cover soil behavior has performed for many years, but there is a review of domestic and foreign literature ash, mostly looks at the aspects of physical and chemical properties and heavy metals, there is no assessment of the casing methane oxidation impact. This paper mainly urban incinerator ash as a research object, and after a landfill cover soil mined to study experimentally analyze the impact of ash added methane oxidation right.

Abstract: High concentrations of ammoniacal nitrogen in fecal sewage pose a great threat to subsequent treatment steps. The conventional removal technique in China mainly involves air stripping. However, the concentration of ammonia in the effluent is often very high, and the fillers in towers could exhibit scaling resulting in reduced lifetime in operation. Because of its high mass transfer characteristics, fluidized bed technology was used in our study of the air stripping method for improving the removal efficiency, using spherical biological ceramsites as the filler. The effects of temperature, pH, and fluidized bed residence time on the removal process were investigated. To compare the various effects of fluidized bed operation on nitrogen removal efficiency, traditional air stripping experiments were carried out using the identical gas flowrate, liquid flowrate, temperature and pH. The results show that the removal efficiency of ammoniacal nitrogen was improved using a fluidized bed. The mechanism of free ammonia mass transfer using fluidized bed technology was proposed. Finally, the filler adhesion problem was reduced and the technology was successfully applied to the air stripping of high concentration ammoniacal nitrogen from fecal sewage.

Abstract: The wind field have been analyzed based on data of auto-meteorological station on the Kangding airport during Mar., May.-Jul., Sep., 2010. Due to the variability of the westerly overhead the airport, it was cold and dry on Mar. and rainy season started on May. The downward momentum transportation directly enhanced the surface westerly wind velocity at about 14:00 in Mar. and May.. In summer, the strengthen easterly wind by head-induced circulation influenced the airport when the air temperature started to fall after sunset on sunny day. In addition, the northerly tail-wind only appeared at about 15:00 in Mar..

Abstract: The analysis of marine environmental quality is an essential tool for grasping the domain environmental situation. The analysis of marine pollution source could be guide the environmental management and refine the management target. So this research is meaningful for the environmental management. In this paper, the environmental quality and pollution source are analyzed in the Beidaihe nearshore district, Tangshan Bay. The environmental quality standard of the Beidaihe nearshore district is the first level. The land pollution analysis shows that the discharge of Luanhe river has a main influence for the Beidaihe nearshore district.

Abstract: Functionalized MCM-41 have been prepared with 3-aminopropyltrimethoxysilane (APTMS) as organic component and metal cations as inorganic component. The effects of different metal cations and concentration of APTMS on desulfurization performance for tert-butyl mercaptan (TBM) were investigated. The transmission electron microscopy (TEM) results indicate that the hexagonally ordered structure of MCM-41 remained intact after functionalization. The presence of grafted organosilanes was confirmed by fourier transform infrared (FTIR) spectra.
