The results showed that the compacts had higher density and microstructure homogeneity when the sintering temperature of the compact was decreased; and that the surface microstructure, densification and mechanical properties of the sintered body could be ameliorated obviously.展开更多

The pressure faced currently by the oil refining industry in terms of resources avalibility and environmental regulations was analyzed. The key elements associated with the refining industry restructuring to economize on all kinds of resources were discussed and presented. It is stated that the key for building an energy and materials saving oil refining industry should rely on the adoption of advanced process and engineering technology, adjustment of refinery configuration, improving the energy and resources utilization efficiency, deep processing of crude oils, optimizing all kinds of resources, reducing effluents by saving water, as well as boosting the integration of oil refining with chemical production, concentrated disposition and realization of large scale of process units.展开更多

This article also suggests that the trend for future development of global refining industry is focused on the economy of scale for the refineries and the oil processing units, the refining structure readjustment, integration of the oil refining and chemical production and formation of oil refining bases. The oil refining industry will uninterruptedly rectify its industry allocation and processing unit configuration and strive for the reduction of production cost through technical progress and management innovations to reduce the production cost, boost the profitability and sharpen the market competitive edge.展开更多

The aim of the research was to achieve optimal performance by the athletes during the kumite1 in karate. The research involved initial, control and final experiment, where the karate practitioners were focused on the training model given （group; n = 13） and working in a group with additional individual intensive sessions provided for each participant. All athletes were male contestants aged 26.4 - 6.8. The aim of the research was to explore how their performance can be influenced using psychological techniques during karate trainings, or how not to fall into one of the four undesirable states of mind called Shikai2. Results confirmed that the model of combined physical and mental training for athletes improves their physical skills and optimizes performance during competitions.展开更多

And generally speaking, trainers or teachers will introduce those techniques to the students respectively. Yet in this paper firstly, by taking examples from some of the text books and a few famous conferences in China, it makes a comparative analysis of the different techniques in translation and interpretation. The comparative analysis explores the most three common techniques： amplification, omission, and repetition in translation and interpretation, and draws the conclusion that translation is more formal, more rigorous, while interpretation is comparetively simple and flexiable. Based on the above analysis, then the paper suggests that the comparative analysis approaches should be used during the teaching process instead of the traditional one-way teaching.展开更多

It is with educational effectiveness, which can be used by educators. Modem sports trainings are designed to develop and enhance the athlete＇s physical and psychological level and other aspects. In the process of the competitive sports training, Olympic spirit has brought certain education enlightenment to the technical and tactical innovation, ideology and morality, learning and using for reference and confidence in training four aspects.展开更多

Outward Bound activities in favor of school to further implement the national education policy, to promote the implementation of the Sunshine Sports to promote campus spiritual civilization, to broaden the space of Physical Education; same time it is also beneficial to develop students ＇interest in sport, develop students＇ teamwork, to promote the physical and mental health of students, improve students＇ social adaptability. To expand the training to maximize the function of colleges and universities, but also in the education sector especially sports workers continue to work hard, make a greater contribution to the development of universities and students.展开更多
