According to cbr and jig ' s structure feature , mainly discuss how to represent jig structure , how to organize of case base , how to retrieve the similarity case . at last , a jig design algorithm model based cbr is put forward 通过对cbr技术的研究，结合型架的结构特征，重点研究了型架结构实例的表达方法，型架结构实例库的组织方法，型架结构实例的检索方法，建立了基于cbr技术的型架设计算法模型。
Finally , on the background of the project " research of the satellite information resource management and share system " , the thesis provides an example of the three - view security architecture , which verifies the feasibility and practicability of the three - view model 最后，以“卫星信息资源管理与共享系统研究”课题为背景，给出了一个三视图的安全体系结构实例，进一步说明了三视图模型的可行性和实用性。
In the thesis , the author researches how to express the die case , organize the case base , and retrieve the case . at ( he key nearest algorithm system , fuzzy reasoning is used to retrieve the case according to the similarity between the die structure cases . the system also provide a strategy to reuse the retrieved case and make the system can study by itself 论文中提出了模具智能化cad系统的体系架构和智能化方案；将基于实例推理的技术应用到模具结构设计当中，针对这个问题详细的讨论了模具结构实例的表达，模具结构实例库的组织，模具结构设计过程当中针对具体的应用情况如何进行模具结构实例的检索；本文应用模糊推理技术采用了权值邻近法根据模具结构实例之间的相似度进行模具结构实例的检索，并且给出了系统再学习的具体策略，使整个系统具有自学习的功能。
A large astromesh deployable antenna which is a project supported by state committee was designed and analyzed in this paper . the design and analysis process was described in detail . through the parallel analysis of four common type of cable - net for astromesh antenna and the parameterized analysis of every kind of structural parameter , the influence to static and dynamic characteristic of astromesh deployable antenna by the type of cable - net and every kind of structural parameter was given out 结合课题组承接的科研项目，对一大型环形桁架可展天线结构实例进行了设计与分析，对设计分析的各个环节进行了详细的阐述，通过对该类天线四种常用索网形式的对比分析及各类结构参数的参数化分析，得出了索网形式及各类结构参数对其静、动力特性的影响规律，对此类可展天线的设计具有指导意义。
