Abstract: Ever since Pierre GuBaidan and his colleagues restored the Olympic Games at the end of the19th century, the modem Olympic Games have evolved for a. hundred years during which they experienced both hard and exciting moments. Although according to the history, the 1916's, 1940's and 1944's Olympic Games were cancelled because of the war, although frequently chaotic arose from the inside of the organization of the Olympic Games and some external pressure arose from outside of the organization, the modem Olympic Games are still regarded as one of the few successes which elaborate the internationalism. Starting from a humble, indefinite beginning, the Olympic Games gradually grow into a marvelous sporty event in the world; nowadays, not any other event can compare with it in the style, scale or in the complexity of the organization. Each past Olympic Games is an important opportunity for exchanging the ideas in science and cultural, and it also provides a giant stage to the hosting city, demonstrating the hosting city's history, culture as well as the resident's expectation to the audience of the world.

Abstract: The dissertation targets on the evolvement of the Olympic architectures together with the analysis of some concrete historical cases. The dissertation has been divided into two halves, which are logically related. The first half is organized as follows: first, the historically evolvement of the Olympic Games over the past 100 years was illustrated via 4 important phases. Then it concluded the characteristics on the space layout of the Olympic architectures. Finally the technical and economical influences on the Olympic architectures were analyzed in detail. Within the second half, for each of the four characteristic stages, detailed elaborations were launched to cover the unique characteristics of the Olympic architectures in each stage chronologically.

Abstract: With the development of higher education, college sports architecture is no exception in the revolution. Due to many factors, such as economic, sports science and technology, the development of Europe and the United States and Japan and other countries of the sports building has been at the forefront of the world. At the same time as the Europe and the United States, Japan and other countries recognize in the mass sports, competitive sports and school sports are abundant, and established a relatively perfect sports club system, at the same time, many large-scale sports events and commercial events are held in Colleges and universities. These are vigorously promoting the construction of college sports architecture. Many college students in Europe and the United States, in the school the sports entertainment facilities in Colleges and universities are available as an important condition for the choice of schools, the quantity and quality of sports facilities has become one of the window to show the strength of the competition, promote the sports facilities in Colleges and universities to develop.

Abstract: The pressure hull is the most important part of resisting pressure structures of the structural systems. The submerged pressure hull is subjected to very high hydrostatic pressure or underwater explosion load, which creates large compressive stress resultants. Due to this the pressure hull is susceptible to buckling. Buckling phenomena analysis is of greater importance in the design of the submerged pressure hulls. For the pressure hulls with local out-of-roundness, the operating depth will be greatly influenced and thus decreasing capability to resist pressure loading. Thus, this work employs the ABAQUS finite element program to analyze the effect of roundness on the buckling strength for the cylinder pressure hull. Sex kinds of out-of-roundness rateφ, 0%, 1%, 3%, 5%, 10% and 15%, were studied in this study. The bulking depth and collapse depth for the cylinder pressure hull with different out-of-roundness rate were calculated. The Analysis models and results of this study contribute to efforts to design pressure hull structures.

Abstract: In recent years, energy crisis increases, energy saving and environment protection have become particularly important. With the improvement of people's living standards, energy demand is increasing; therefore, building energy conservation is imminent.Building energy efficiency needs much attention and implementation, which covers construction units, design units and supervision units. Construction of the building energy efficiency is full of the entire construction process. From planning, design, construction to supervision process is all in control. The lack of a link monitoring is likely to result in an increase in energy consumption. Resource engineering supervision is an important construction implementation process, and is an important link in the process of building energy conservation monitoring.Building energy conservation.

Abstract: China is rich in resources of heavy oil.But some oilfield heavy oil reservoir in the development process will encounter interlining, affecting the development effect. In the process of SAGD to carry out the basic research of reservoir interlayer is helpful to identify the basic attributes of reservoir in the interlayer. The interlayer of SAGD development process is helpful to find the study focus and direction of development. Steam chamber breakthrough research achievements of interlining research abroad, summarizes the steam chamber breakthrough interlining, provide technical support for the oil field SAGD breakthrough interlining, it is of great significance for promoting SAGD efficient development.

Abstract: In this research, both un-deformed or Lagrangian state and deformed or Eulerian state are used to derive for stability analysis and large deformation. By choosing the deformed radius of curvature and deformed angle of tangent slope as parameters, the governing equations of laminated curved beam under static loading are transformed into a set of equations in terms of angle of tangent slope. All the quantities of axial force, shear force, radial and tangential displacements of circular thin curved beam are expressed as functions of angle of tangent slope by using laminate theory. The buckling load and large deformation analytical solutions of circular thin curved beam under a pair of forces are presented as well.

Abstract: The horizontal section of a covered sheet pile wharf is investigated to indicate that covered effect includes soil arch effect on land and soil pile interaction. Transfer formula for horizontal thrust acting on the plane of covered sheet pile on land and the method of horizontal earth pressure are derived. Based on the observational data of 32# berth in covered sheet pile wharf at Jingtang Port, the method of horizontal earth pressure is verified to be rational. Representative soil layer is analyzed to demonstrate that the difference in covered effect decreases with increasing pile spacing; covered effect decreases with increasing section width; covered effect increases with increasing section length.

Abstract: There is an increasing interest in tea polyphenols, as natural plant compounds, in food products and also in pharmaceutical products due to their multiple health care functions. In this paper, a microwave-assisted extraction method was employed for the extraction of tea polyphenols. The effects of microwave power, heating time, and ethanol concentration on extraction of tea polyphenols were investigated by single factor experiments and an orthogonal experiment [L₉(3)³]. Results showed that the optimum extraction conditions were that the microwave power was 560W, the heating time was 30s, and the ethanol concentration was 40% (v/v). The antimicrobial properties of tea polyphenols were also discussed. Tea polyphenols had bacteriostatic activity against Escherichia coli and Staphylococcus aureus. This study may be valuable for the extraction and application of tea polyphenols.
