Abstract: In order to determine the health status of Larix principis-rupprechtii plantation in the Eastern Inner Mongolia, the field data were surveyed and then the principal component analysis, mean-variance analysis method and fuzzy comprehensive evaluation method based on Fortran program were comprehensively applied to evaluate these forests in this study. Results showed that the health grade of Larix principis-rupprechtii plantation was 2.267. The health grade was between the sub-health and medium health, which was lean to the sub-health in the eastern Inner Mongolia.

Abstract: Accompanying the reform and opening up of economic construction and social development of democracy in China, Grassroots' annual income is increased significantly, but Physical fitness is declining. Controlling Population and improving the quality of the population are China's basic national policies. To solve the problems of low per capita health care resources and space and time limitation of sports activities, this paper analyzes the bidirectional impacts between grassroots' physical fitness and sports medical projects. The study collects power, speed, stamina, agility, flexibility and other basic data of local residents in Guangxi to calculate the composite score of the physical quality of the local residents, and uses the multiple linear regression models to analyze the impact of community sports projects and basic medical projects on residents' physical fitness. The results show that the economic development has little impact on the improvement of residents' physical fitness while community sports physical and medical projects have some impacts. Therefore, we should increase investment for sports medical projects, expand the scope of medical services, and provide more sports area and sports equipments program to improve the physical quality of the residents.

Abstract: with the rapidly development of modern education, the degree of integration of information and modern education has been strengthen continually. The new education model of information technology and modern education is related with traditional education. They are complete and mutually promote in the teaching process. This paper analyzes the basic connotation of psychology teaching. Based on the principle of teaching and research mission of the psychology, this paper profiles psychology teaching feedback and coupled revelation of information communication model. This paper establishes psychology teaching multi-dimensional interactive model of the IT environment using the qualitative analysis method. This paper determines the effectiveness of teaching effectiveness through the effectiveness of the computer information entropy which provides a theoretical basis and practical guidance for the psychology teaching reform and innovation.

Abstract: Currently, listed companies in our country generally draw up consolidated financial statements according to the new accounting standards requirements, and release consolidated financial statement to investors and relevant financial statements users so as to public company financial information. Consolidated financial statements can comprehensively reflect the financial position and operating results of listed companies. The key basic work of consolidated financial statements preparation is to reasonably determine the consolidation range of consolidated financial statements. Although the current new accounting standards have stipulated consolidation range, the new accounting standards has not specified the substantial control of concrete measurement method problem. So this paper takes one listed companys financial report and related data from 2007 to 2011 as data sources,selects listed enterprises with no clear merger reason as research object. Multivariate linear regression model is adopted to analyze the influence of merge scope change on book performance. The results show that the consolidated range change will change enterprises book report data,and the influence average value of book achievement is about 10.72%.

Abstract: That the basic education reform conforms to the demand of teaching development as well as the professional capabilities, teaching level, and teaching effectiveness of experimental class teachers are supposed to be improved has become the important objectives of developing and optimizing the experimental teaching reform. This paper firstly analyzed the present situation of experiment teaching effect evaluation , and then analyzed the advantages of gray evaluation method in the experiment teaching effect evaluation compared with the traditional experiment teaching effect evaluation. Thus this paper built the optimized experiment teaching effect optimization system by further applying the gray evaluation method to analyze and evaluate the experiment teaching effect and then optimize teaching evaluation process, and finally improve work efficiency and evaluation accuracy .

Abstract: At present, there are many problems existing in railway stations, such as excessive numbers and over-crowded layout, which seriously affect the scale benefit generation and rapid expansion of rail freight capacity. Aimed at these problems, a Mixed Integer programming model is proposed. Taking Lanzhou train operation depot for example, applying lingo software, the layout of freight station is obtained.

Abstract: in recent years, with the development of the chemical industry, marine liquid chemicals a steady growth. Research guidelines for the safe operation of dangerous chemicals in bulk liquid, and to ensure the smooth operation of bulk liquid chemicals Terminal, meet the needs of production and domestic and foreign trade, creating huge economic and social benefits, while safeguarding the operational safety of bulk liquid chemicals, maintenance of port operations, protection of shipping, handling, storage, safety of lives and property as well as the entire city is of great significance.

Abstract: in order to understand the use of research and development resources of high-tech enterprises in western China, the research and development efficiency evaluation index system is built from the research and development expenditures, research and development personnel, profitability, development ability and technological innovation ability in this paper. DEA method is applied to evaluate the relative research and development efficiency of 27 listed high-tech enterprises in western China. Empirical results show that the overall level of all samples is not high, and most of the enterprises are in inefficiency stage. There is direct proportion between size of assets and R&D efficiency for enterprises.

Abstract: Whether Giffen goods exist or not has long been a argument in economics academic circle. This paper analyzes and evaluates the two opposing arguing points represented by Zhang Wuchang and Wang Dingding. At the same time, through analyzing in depth the explanation offered by Hicks Decomposition to Giffen goods in economics textbook,the paper points out that Hicks Decomposition to Giffen goods is against the axiom of Diminishing Marginal Utility, so that Giffen good is not likely to exist in reality.

Abstract: Based on the theory and methods of early evolution rule of cascading failure, the paper puts forward a kind of cascading failure selection and risk analysis method basing on the system failure severity, which can availably take consideration of the interplay of the before and after fault as well as the cumulative effect between successive failures. IEEE RTS-79 system is taken as an example to illustrate the effectiveness of the algorithm.
