摘要：Based on the introduction of the connotations and characteristics of tourism industrial eco-network,it has expatiated on the connotations of and approaches to enterprise coupling in tourism industrial *** there are different understandings and definitions of these connotations,the following four aspects must be achieved in order to realize coupling in the real sense for the enterprises in the network.① Establish the idea of "the whole is larger than the sum of all the parts",and construct interests community of tourism industrial eco-network.② Construct cooperation mechanism of joint struggle to transfer the advantages of the single to the advantages of the whole.③ Create and maintain strong service culture.④ Avoid as many service blunders as possible and construct damage warning mechanism in industrial *** the construction of the game model of tourism enterprise coupling and corresponding analysis,the results indicate that the mode of loose cooperation between enterprises in the tourism industry could hardly reach any forceful binding *** it is hard to realize the coordinated effects brought about by the cooperative game of tourism enterprise coupling and these enterprises would often come to a "prisoner dilemma" because of present tiny *** the end,it suggests that during the process of competition tourism enterprises should also strengthen mutual cooperation as relying upon the platform of industrial eco-network.

摘要：合作学习是一种富有创意和实效的教学理论与策略体系,常以cooperative Group的形式出现,以学生为中心组织学习活动,最终达到改善课堂心理气氛、提高学习主动性、促进良好的非认知品质的目的。本文浅述了Discussing法、PPT Show法、Telling-story法、Roleplaying法等四种cooperative Group学习方法策略,以期改变传统教学模式,提高大学英语课堂教学有效性。

摘要：Several protocols and schemes have been proposed to reduce energy consumption in Wireless Sensor Net-works (WSNs). In this paper we employ farcoopt, a cross layer design approach with the concept of coop-eration among the nodes with best farthest neighbor scheme to increase the Quality of Service (QoS), reduce energy consumption, increases performance and end-to-end throughput. We present cooperative transmission to connect previously disconnect parts of a network thus overcoming the separation problem of multi-hop network. We show that this approach improves connectivity over 50% compared to multi-hop approaches and reduces the number of nodes necessary to provide full coverage of an area up to 35%. Simulation results show that on increase of data rates i.e. packet the network life time increases in farcoopt as compared to tra-ditional multi hop approach. The result of this analysis is presented in this work.

摘要："二元协同材料"这一新概念,不同于传统的单一体相材料,是在材料的宏观表面或体相内建造二元协同纳米界面结构.该材料设计原理是,在介观尺度引入不同甚至完全相反理化性质的纳米微区,在某种条件下具有协同的相互作用,以致在宏观上呈现出超常规物性的材料.这一新原理的关键是找出这两种组分间的协同距离,该协同距离应该与物理或化学中的某一特征常数相关.这一设计原理可以拓展到材料科学的多个领域,用于指导制备各种新型功能材料.

摘要：并发控制是CSCW环境下协同设计中复杂而又关键的问题之一,分析几何信息模型对象特征之间的联系,建立特征之间的相交和约束关系。运用模糊数学分析方法,提出一种优先权限分配算法,给出版本管理的解决方案。设计和实现针对共享对象协同操作的一致性维护和并发控制算法,并通过实例验证算法有效性。
