( 4 ) throw the study of the first four vibration modal of reinforced earth retaining wall and the analysis of twelve reinforced earth retaining walls with different height and different materials using ansys programe , the basic discipline of the first four vibration modals of reinforced earth retaining wall is gained ( 4 )对加筋土挡墙的前四阶振型进行了研究,采用ansys有限元程序分析了12个不同墙高、不同材料的加筋土挡墙,得到加筋土挡墙的前四阶振型的基本规律。
In this paper , according to the approach and engineering reality condition , an semantic based information extraction system has been designed and wrote some codes and implemented the system , so in this paper , the main frame and the designing method of main modals in detail are introduced 根据上述方法并结合工程实际情况,设计了一个基于语义的信息抽取系统。在本文中,提出了基于语义的信息抽取系统的总体框架、各主要模块的设计,还着重说明了基于语义的信息抽取方法。
Secondly , it discusses theories of representation of graph characters , tcp / ip protocol and three layers system structure , based on which we give a notion modal of instant messenger based on graphs . there are three - layer and based on tcp / ip system structure and function modals consisted of user management modal , graphs communicating modal and history record modal etc . in this notion modal 在理论研究的基础上提出了基于图形的即时通信系统的概念模型,在该模型中描述了采用三层系统结构、基于tcp / ip协议进行网络通信的系统结构模型和包括用户管理、图形交流、历史记录等模块的功能模型。
