This paper studied the method on the detection of network islands after faults , which is based on layer - separation and region - separation of network topology , the searching technique is applied to the analysis of the power system topology , simplified the process of the detection of network islands 本文研究了分层式的电网解列判断方法，应用人工智能的搜索技术，进行电网拓扑搜索，以判断电网是否解列，简化了电网解列判断的过程及其前期准备工作。
In this paper , urea particles and oil - vegetable seeds as initial particles are used to study granulation process in a vibrated fluidized bed , where the initial particles grow in a layered manner by spraying melt urea solution on them and reached the required granule size 本文以尿素或油菜籽颗粒为晶种，以不同浓度的尿素溶液为喷雾料浆，对振动流化床喷雾造粒特性进行了实验研究。实验在晶种上喷涂尿素熔融液或不同浓度的尿素溶液，使其以层式机理长大。
Metropolitan area is a kind of circle structure of towns in which towns have close social and economic ties . it derives from the development and evolvement of city system , and people also used it as a spatial form in orginazing city system 都市圈是指由一个或多个核心城镇，以及与这个核心具有密切社会、经济联系的，具有一体化倾向的接城镇与地区组成的圈层式结构，它既是城镇体系自组织的一种空间形式，同时也是人们加强城镇联系、协调城镇发展的一种手段。
On the basis of the strategy of sustainable development , by our country ' s character of high dense population , high density use of urban land , tight concentrated form , single center tight configuration , paper applies coordinated idea of transport plan and land use plan , insists on the principle of public traffic development priority , seeks a high accessibility low demand model of land use and transport , bringi forward a new plan method of transit - oriented dev elopment to deal until connection between the effective use of urban land source and continual increasing demand of transport , thoroughly solves urban transport congest problem resulted by the imbalance of supply and demand of transport . also paper detailed analyzes and studies the concept , soit . general design principles , particularity of transit - oriented development region 在可持续发展战略的指导思想基础上，论文根据我国城市人口高度密集，城市土地高密度利用，以集中紧凑型为主的布局形态，单中心圈层式紧密结构的特点，运用交通规划与土地利用规划的协同观念，坚持优先发展公共交通的原则，寻求高可达性、低交通需求的土地利用? ?交通系统发展模式，提出以公共交通为导向的城市土地利用形态的新的规划方法，处理好有效利用城市土地资源与不断增长交通需求之间的关系，从根本上解决交通供求关系不平衡而造成的城市交通拥挤问题，并对公共交通运输导向开发区的概念、分类、设计总则、特质作了详细分析研究。
After analyzing the main models of vod system currently , the author provides readers new vod system of hierarchical storage based on proxy . the author also describes the architecture and their functions and the design and the implement of the software on the vod . incorporated with network communication , hierarchical storage and several replacement algorithms , the new system is more dependable and practical 作者在深入细致地分析、比较了当前常见的视频点播系统的设计原理、设计思路、实现方法及其性能优缺点后，提出了一种新型的基于代理的分层式的vod解决方案，阐述了该解决方案中的设计思路、设计原理、各部分的组成、功能以及设计方案实现过程。
