This paper shows that analysis system procedure on the coupling vibration of vehicle - bridge can alone research vehicle vibration , bridge vibration and can still research vehicle - bridge on coupling vibration . moreover , from the external data document to calculation , then to the result output can proceed together . the interface of procedure is amity , operation is simple and the function is strong 本文研究表明,车?桥耦合振动分析系统程序可以单独对车辆、桥梁进行振动分析,还可以对车?桥耦合振动系统进行分析,并且从外部数据文件,到计算求解,再到结果输出可一并进行,界面友好,操作简单,功能较强。
The present paper puts forward a new technique for stabilizing spectrum by rewriting spectral data document with computer software , which , based on gamma - ray holospectral survey and getting rid of radiorctive nuclide source , can remedy the defects existent in hardware spectrum - stabilizing technique and further improve the spectrum - stabilizing technique 摘要本文提出了一处基于射线全谱测量,摒弃放射性核素源,采用计算机软件重写谱数据文件进行稳谱的新技术,以弥补硬件稳谱技术的不足,并使稳谱效果更好。
The program composed of many function modules in construction can realize different function , and the main design parameter is transferred by data document . so it can really reinforce the drawing ability of software and make the software ' s update and maintenance become convenient 这一部分程序在结构上主要采用了函数模块组合的方式,通过不同的函数模块组合实现不同的功能,主要设计参数也通过数据文件的形式进行传递,这样可以大大加强软件的绘图能力,同时也使软件的升级维护变得非常方便。
The author divides the middle ware into three parts : source data controlling part , middle data document , aiming data controlling part . the middle ware uses the scheme of middle data source : taking data out of the source data table ; then , restoring the source data into the middle data document to reorganize these data and making them acceptable to the aiming data table ; finally , putting these organized data into the aiming data table . additionally , in the designing , the author writes the data types contrasting tables of heterogeneous databases by xml ( extensible markup language ) documents , and uses the xml document as middle data source 本文主要阐述了在异构数据库之间进行数据传输中间件的设计和研究:把中间件设计成三层结构,即:源数据控制层、中间数据源层、目的数据控制层;并采用中间数据源的解决方案,从源数据表中读出数据,经过中间数据文档的中转传送到目的数据表中;在该系统中,使用xml ( extensiblemarkuplanguage ,扩展标记语言)文档来设计各数据库与xml之间的数据类型映射表,并使用xml文档作为中间数据源;对xml文档的结构定义使用xmlschema ;使用jdbc - odbc桥来连接数据库,并对数据库进行操作。
The computers play the important role in the information society today , more and more enterprises , merchants , government departments and the persons depend on the networks to get and to process the variety of information , to save them onto the storage of the computers in the form of data documents 在信息化时代计算机扮演着越来越重要的角色,越来越多的企业、商家、政府机关和个人通过网络获取信息、处理信息。同时人们将大量的重要信息,以数据文件的形式保存于计算机或存储器中。
