Abstract: With the development of science and technology, the requirements on the properties of new materials was increasing, polymer materials become one kind of important material type which has been widely used in the current human social activity. Due to its high properties such as strength, elasticity and toughness, polymer materials with high mechanical properties’ application in the field of competitive sports has incomparable advantages. This paper analyzes the characteristics of high mechanical properties of polymer materials and its advantage in competitive sports, in order to promote its application in the field of sports.

Abstract: Since China's reform and opening up, with the rapid development of our country economy, people living standard rise, the progress of science and technology as well, Modern surveying and mapping technology plays a very important role in both subject theory, technical level and in terms of application scope, have taken place in the larger changes, to solve the problem of social development and the national economy. In this paper for the application and development of surveying and mapping technology is also discussed and prospected.

Abstract: With the concept of an environmental-friendly and energy saving society deepening, people are enhancing their demands of the green ecologicalization of modern packaging design. With the continuous development of products and packaging forms, packaging materials presents a development tendency of diversification. The maturity of people's concept of environmental protection promotes packaging designs transform into green ecologicalization. The green ecologicalization of packaging designs and packaging materials is undoubtedly a main direction of packaging designs in the future development. Based on this point, this article discusses about the application of green ecological packaging materials in modern packaging designs.

Abstract: So far, the research on instructional design theory has been influenced by behaviorism, cognitivism and constructivism, forming a variety of researchs on positioning and orientation. In the aspect of teaching, theory of instructional design has not played the proper role. This paper analyzes the application status of theoretical ability of instructional design and instructional design of primary and secondary school teachers, and put forward some countermeasures for solving the current problems.

Abstract: Through the introduction of the application situation and basic properties of recycled concrete,the author analyzes its application value and and research direction in engineering application,and then puts forward to the application prospect of recycled concrete in road engineering.

Abstract: Abstract: With the rapid development of computer technology and theoretical concepts and constantly updated network technology, computer technology applications in the field of education more widely. Application of computer technology in higher education, not only can improve teaching effectiveness and efficiency, but also enrich the teaching content and teaching methods to stimulate students' interest in learning, thus improving the quality of teaching.

Abstract: Building construction usually delay by various kinds of reason during construction and equipment installation process. It maybe cause total duration to be delayed by one work delaying, also it maybe not affect the total duration. It depend on nature of the work and time delayed above the two situationgs. Firstly activity-on-arrow network is introduced in the article, secondly critical path and total float are analysed, then we have controlled and analysed the construction progress by using total float in the actual projection, finally we have made the conclusion.

Abstract: In recent years, with the excellent mechanical properties, good thermal conductivity and electrical conductivity and optical properties, Graphene is widely used in many fields such as chemistry, physics and material science .The preparation of graphene have had a very big progress.This paper reviews the chemical preparation methods of graphene and the application of Graphene / Chitosan composite.Then we point out the outlook of the application of the composite materials graphene with other biological macromolecules which are similar with chitosan.

Abstract: The water quality model is an efficient tool for water pollution control, water quality planning and environmental management. In accordance with the need of prediction, analysis and management of water quality, this article presents different application conditions for various water quality model, including zero-dimension, one-dimension, two-dimension and multidimensional. Then the application of water quality model in different areas are summarized here.

Abstract: An earthworm-assisted phytoremediation of Cr contaminated soil was conducted to study the performance of different earthworm species in Cr accumulation of Vetiver Grass (vetiveria Zizanioides VG). Two species of earthworm (Eisenia Foelide and Pheretima guillemi Michaelsen) were added in trial. The result showed Vetiveria Zizanioides can absorb great amounts of chromium in soil. The decline rate of Cr was up to 87% and 78% respectively in the tiral of Eisenia Foelide (EF) and Pheretima guillemi Michaelsen(PGM) at 60^th day. As the concentration of Cr gradually increased within 3.3-120mg/kg, the accumulation activity of two groups presented first increase and then decrease and reached maximum 976.7mg/kg and 943.1 mg/kg in root. It began to decrease when the Cr concentration was above 120mg/kg.Vetiveria Zizanioides's accumulation ability differs in root and shoot. It presented root>shoot. With a comparative analysis, PGM has higher accumulation and resistance to Cr at any designed treatments. In the analysis of relation between plants and soils, it was found that there was significant correlation in Cr contents between plants and soils (P<0.05). There was a high retention rate of Vetiveria Zizanioides root to Cr. Retention rate of any treatments adding earthworm were all greater than 87.91%. The biggest value was up to 96.23%. There was no obvious difference between EG and PGM in retention rate.
