Abstract: In this work, we mainly summarize the influence of the ion bombardment cathode (target) and relative factors of magnetron sputtering yield in production thin film. Magnetron sputter deposition permits a much wider selection of film materials, produces films with higher purity and better controlled composition, provides films with greater adhesive strength and homogeneity, and permits better control of deposit thickness. Unlike most other work described about sputtering yield, sputtering for thin-film production is performed using the plasma rather than a focused ion beam. When an ion with the energy hits a surface of the target, a small fraction of the energy and momentum of the incoming ion will, through lattice collisions, be reversed and may cause ejection of surface atoms (sputtering). The average number of the atoms ejected from the cathode surface per incident ion is called the sputtering yield. The sputtering yield varies with the target material, the kind of impinging ion, and the energy of that ion. At a given ion energy, The sputtering yield increases with increasing angle of incidence up to a maximum at an angle between 55 ° and 85 ° with respect to the surface normal [1, 3].

Abstract: The ecological footprint model with food, house, energy and waste as consumption accounts through analysis of urban matter and energy consumption was established. Based on 2000-2009 data of Fushun, a resource-based and heavy industrial city, ecological footprint, ecological carrying capacity and ecological surplus/deficit of Fushun were analyzed, respectively, and then urban sustainable development status was evaluated. The results show that the urban development state is ecological deficit and ecological deficit index have been increased from 5.227hm²/cap to 6.516hm²/cap during 2000-2009, Fushun is always under an overload condition, which is highly unsustainable. The ecological footprint is 89.39% made up by the fossil energy footprint on average, the main consumption of Fushun's development are fossil energy land. And then urban 10⁴ Yuan GDP ecological footprint index decreased from 5.660 hm²/cap to 2.247hm²/cap during 2000-2009, the urban energy utilizing efficiency have been improved.

Abstract: The low cycle fatigue behavior was experimentally studied with the 3-dimension notched LD8 aluminum alloy specimens at 300°C. The 3- dimension stress-strain responses of specimens were calculated by means of the program ADINA. The multiaxial fatigue life prediction was carried out according to von Mises’s equivalent theory. The results from the prediction showed that the equivalent strain range can be served as the valid mechanics for predicting multiaxial high temperature and low cyclic fatigue life.

Abstract: In order to answer following two questions, One is the influence factors and the influence degree of Nanjing enterprise emission reduction，Another is in the future five years Nanjing City enterprise COD and SO2 emissions trend prediction. This paper begins with a qualitative analysis of factors affecting enterprise emission reduction in Nanjing City, resulting in the classification of these factors according to their importance and significance by using the Grey Correlation Analysis method; Based on the fact that enterprise emission reduction in Nanjing system is gray, this paper established the Grey forecasting model GM (1, 1), 2011 ~ 2015 Nanjing enterprise COD and SO2 emissions was forecast. This paper studies showed that Nanjing emission reduction is the basic health; As long as continue to strengthen the work of emission reduction, in the next five years, Nanjing enterprise COD and SO2's total emissions will continue to decline.

Abstract: Analyzing the typical management pattern of agricultural produce logistics, this paper discovered that the dominant of the pattern and got more profit because of the information fully. In view of this status quo, the agricultural products logistics management pattern based on information center was built. The advantages of the pattern were explained. The pattern was demonstrated by the orange logistics management pattern based on information share,the result showed that the pattern is effective and practicable.

Abstract: Urban rail transit plays a role of activating and leading regional economic development. It influences the spatial distribution of urban agglomeration and the progress of regional economic integration. It is a kind of virtuously cycled interactive relationship between regional economic development and regional rail transit. This paper analyzes the effect of urban rail transit construction project on regional economy based on the economic benefits arisen from it. The research results show that China’s urban rail transit construction and regional economy can not realize balanced development unless the fact that the relationship between urban rail transit planning and regional economic development can be well coordinated, and meanwhile, the construction scale and service level of different phases of rail transit can be confirmed according to urban economic development level.

Abstract: Due to specific geological conditions, stability of complex high slopes has become one of the key technical problems in hydroelectric project. Especially for steep-high rock slope, it is hard to calculate the stability by normal rigid limit equilibrium method. Steep-high rock slope in Jiangping River hydropower station is taken for example. On the base of study of geological structure and judgment of preferred structure plane, simplified geological model is built up. The main deformation destruction mode and type are analyzed based on block theory, rock mechanics and other basic mechanics while the related critical values are calculated. So slope stability is discussed and corresponding control measures are worked out. This method can be used in following stability research of similar slope.

Abstract: a new rosin derivative—methylthiomethyl dehydroabietate has been synthesized from dehydroabietic acid and DMSO. The effects of reaction temperature, time, the amount of catalyst and mixing molar ratio of reactants on the yield have been investigated. The optimum reaction conditions were: the reactants were kept at 215 oC for 3h with dimethyl sulfoxide/ dehydroabietic acid mixing molar ratio of 22: 1 in the presence of 0.4% KOH catalyst ( based on the mass of dehydroabietic acid). The yield of product could reach 90%. The precise structure of the product was characterized as methylthiomethyl dehydroabietate by GC-MS, UV, FT-IR, High-Resolution Mass Spectrometry, ¹HNMR and ¹³C NMR.

Abstract: The paper develops a two-state-variable environmental growth model to derive the optimal growth path for the relationship between pollution and economic growth, which is used to verify the existence of the Environmental Kuznets Curve (EKC) hypothesis. It is found that the theoretical outcomes imply the existence of the EKC relationship between environmental degradation and economic growth, which is dependent on the combining effects of the pollution intensity, abatement technology of pollution emission, production technology, and the return rate of capital stock.

Abstract: This paper made a comparative study of the distribution and quantity of bacteria, actinomycetes, fungi and different bacteria physiological group in different reclamation years and different soil layers with the soil in different reclamation years as experiment material, adopting flat-panel culture and microbial selecting culture medium and using accounting of gradient plat-panel coating. The results showed that: with the extension of reclamation years, microbial quantities are rising overall. The microbial quantities (bacteria, actinomycetes and fungi) in the cultivated land of 200 years were 4.94 times higher than those in the uncultivated land; the microbial quantities in the surface soil of 200 years were 2.16 times higher than those in the deeper soil. The soil microbial community structure of agricultural land has been changing with the extension of reclamation years and the quantitative relation of the three main microbes was: bacteria > actinomyces > funfi; As the uncultivated land become developed, the microbial diversity index and the quantities of physiological group reduced after increasing in the beginning, but the regularity for change of physiological group diversity index is not obvious.
