摘要：Through investigating vertical greening plants on the campuses of Hainan University,it was found that there are 41 species vertical greening plants with excellent landscape effects,belonging to 36 genera and 20 families,among which 4 species are shrubs,33 liana and 4 gramineous *** current application situation of the vertical greening plants on the campuses was briefly analyzed in this study,and corresponding suggestions were put forward in view of the existing problems.

摘要：The main advantage of tail-sitter unmanned aerial vehicle (UAV) are introduced. Three design solutions of rotor tail-sitter lift system of UAV have been presented and the respective control strategies and characteristics of three solutions are also analyzed in the paper, through the related experiments the design of twin-rotor lift system is verified, and its feasibility is proved. The characteristics and the applying background of the twin-rotor tail-sitter UAV are described in detail. Some useful conclusions of the lift system for tail-sitter UAV are obtained.

摘要：在总结现有网格体系结构的基础上,针对所存在的问题,从网格资源使用和功能管理、面向用户操作以及网格系统自身特性等角度分析设计了相应的架构layer、tier和vertical,并且全面考虑这三种架构思想的各个作用因素,提出了基于SOA的三维信息网格体系结构(3DIGA)原型,并对其中一些关键技术和问题进行了研究,提出了一些诸如网格服务代理器、资源集成池、服务工厂等重要的概念。最后将该三维信息网格体系结构应用到海洋信息网格集成系统的软件框架上。

摘要：The accelerating urbanization has brought various problems in environment, land, fund and so on. With the guidance of market economy, economic urban green spaces have become the optimal choice in urban landscaping of China, which can not only improve urban landscapes, ecological environment, satisfy higher spiritual and cultural demands of people, but also create considerable economic benefits, and enhance the coordinated development of economy, society and environment. With Shijiazhuang City as an example, the approaches of constructing economic urban green spaces fit for Shijiazhuang City were analyzed in this study, to provide references for the construction of economic urban green spaces in other cities.
