Second , current p2p discovery mechanism is studied and the problems on chord method are discussed : each node can only know about the information of its succeeding nodes . thus , when some information needs to be searched , the node will check the succeeding nodes in order until the key words are found or the whole network is searched 其次,研究了现有的p2p发现机制,讨论chord方法存在的问题:每个节点只知道其后继节点的信息,这样当进行查找时,节点将依次查询其后继节点,直到找到关键字或者遍历完整个网络为止。
Abstract in order to solve the problems of conventional resource discovery framework , a hierarchy - based model was discussed , which combined super - peer model and contact node , a membership join protocol was introduced , and a resource discovery algorithm was proposed based on time to live ( ttl ) limit and cache list 摘要为了解决传统资源发现机制不能很好地适应网络状态、可扩展性较差等问题，在超级节点模型的基础上，结合联系节点，建立了一种基于层次结构的网格模型，设计了成员加入协议，给出了基于跳数限定、缓存列表的资源发现算法。
At the last , it discusses how to make good use of the capital market to improve the corporate governance . effective corporate governance will primarily give investors correlative information about its management . the quotation discovering mechanism slows down the asymmetry in the information between the investor and the manager , and reduces the investor ' s cost to supervise manager 有效的公司治理首先要求出资人能够得到公司经营的相关信息，资本市场的价格发现机制缓解了出资人与公司经理之间的信息不对称程度，降低了出资人监控经理人员的信息成本，在此基础上，出资人利用资本市场的流动性实现对内部人控制的间接控制，但这一切都要基于一个有效的资本市场。
Originated from the evolution in the realm of economic epistemology and methodology , the author provides with several main incentives to explain the phenomenon . part two : this part is mainly about the institutional research . centered on the essence of asset securitization , the author analyses why this financing method should be introduced into china and how it can be operated smoothly 文章第三部分试图进行理论层面的深入研究：以知识经济时代经济学认识论、方法论的演变为根源，从制度创新的功能驱动机制和金融工程学的价值发现机制等几方面总结了资产证券化的主要动因，并适当结合了制度经济学、经济哲学等学科的思想，力求体现经济学、管理学和金融学在理论分析中的融合与相互借鉴。
As an effective resource allocation mode and price seeking mechanism , auctions have been expanded from the traditional local auctions to the online auctions . it has been an important e - business pattern by means of the extensive transaction means with little limited and the rapid increasing of transaction sum . therefore , researches on online auctions show the essentiality more and more 拍卖作为一种有效的资源配置方式与价格发现机制,已从传统的现场拍卖扩展至网上拍卖,其交易方式的灵活广泛和交易额的快速增长,使之成为电子商务的重要商业模式之一,因此,网上拍卖的相关研究显得愈来愈重要。
This thesis presents a new solution called the smart platform , which better tackles the problems by : 1 ) a runtime environment discovery mechanism which allows a new device to automatically find and join the runtime environment ; 2 ) the loose coupled publish - subscribe inter - module coordination model , which caters for the spontaneous interaction between modules ; 3 ) a global - local two - layer runtime environment structure . the transient failure of the wireless network can be recovered at the local environment layer . the asynchronous nature of the interactions in the < wp = 8 > publish - subscribe model also prevents modules from blocking on the transient network failure ; 4 ) distinguishing two classes of communications with different qos requirements , the message - oriented and the stream - oriented 本文提出并实现了smartplatform ，其特点是： 1 ）运行环境发现机制，使外来计算设备可以自动加入软件平台的运行环境； 2 ）松耦合的发布/订阅式模块间协调机制，模块间关联可以自发组织； 3 ）局部全局的两层运行环境组织策略，无线网频发的暂时故障可以在计算设备的局部运行环境层次被屏蔽掉；同时发布/订阅模型的异步性也使得模块不会因网络故障而阻塞； 4 ）区分智能空间中的两类不同的通信需求面向消息的和面向流的，并分别为它们提供了优化的通信层支持； 5 )基于多agent抽象模型，为整合不同应用领域的模块和遗留代码提供了有力工具。
