4 ) numerical simulation running of surface runoff shows simulation results presented the general features of surface runoff generation , and certain efficiency . after adjusting the input parameters , the simulation results show a good meet to the observed data 4 )表面径流的数值模拟能揭示表面产流的一般趋势,而且有一定的有效性,通过调整模拟输入参数,能使模拟达较理想程度。
In fact , various evolutionary approaches to multi - objective optimization have been proposed since 1985 , capable of searching for multiple pareto optimal solutions concurrently in a single simulation run . spea2 is one of the art of the date algorithms 实际上,自从1985年以来,研究者们已经提出了许多基于演化计算的多目标优化算法,这些算法能够在一次独立的运行中同时搜索到多个pareto最优解。
Among which , database administrator is the window to browse the inquiry component , the environment allocator is the platform for the establishment of simulation run environment , and the environment administrator maintain the natural running of simulation environment as a manager 其中,构件库管理器是浏览查询构件的窗口,运行环境配置器是搭建仿真运行环境的平台,运行环境管理器则是维护仿真环境正常运行的管理者。
On the above theories foundation , this paper will program simulation software for the port ' s tugboat marshaling , at the moment of designing , for the consumer ' s convenience using , the software will save and maintenance the large data of simulation running by adopting the technique of database 在上述的基础上,本文开发了港口拖轮配置的仿真系统软件,在软件设计时,采用了数据库的技术来存储仿真运行时产生的大量数据,方便用户对仿真数据进行维护。
Subject to the physical characteristic of parts , a simplified structural model shall be given by simulation run environment . the structure of component model shall be constituted with the exterior characteristic interface , physical performance interface and simulate control interface in accordance with the connection standard of simulation component for component model realization and with clear function and easily extention 针对硬件部件的物理特性和仿真环境下的特殊要求,仿真运行环境给出简洁的构件模型,由构件的外部属性接口、功能属性接口和仿真控制属性接口组成,按照构件模型实现的仿真构件接口标准、功能明确、易于扩展。
Based on the above study , this topic has realized simulator run environment . after the start - up of simulation running environment with loaded object code , each simulation component shall harmonious run under the logic control of application software , so as to support the software commission and test verification 支持从构件库中选取需要的仿真构件,以可视化图形编辑的方式构造仿真目标硬件环境;加载目标码的仿真运行环境启动后,各仿真构件能在应用软件逻辑的控制下协调运行,从而支持嵌入式系统软件的调试和测试验证。
The profibus - dp bus - mastering network of the system researched in this article was constructed which adopts plc300 as main site and the module of em277 date bus mating with plc200 as subordinate site , through the hardware station construction and the software configuration realized the network communication , and edited the master site procedure to realize controlling subordinate sites , then the master station procedure has been carried on simulation running and debugging 本文研究的系统构建了一个以西门子公司的s7 - 300plc为主站、以s7 - 200plc配合em277总线模块作为从站的profibus - dp总线控制网络,通过硬件建站、软件组态来实现网络的通讯,并编辑主站程序实现了对从站的控制,然后对主站程序进行了仿真运行和调试。
The paper discussed his aims of referring part coding system into dbms , how to choose a perfect coding system and how to modify it to fit the enterprise ' s own conditions . it also discussed the cad electronic files database model , the way to visit it and its integeration with other systems . the simulation running at the end of this thesis proves that the idea is a sound one . the idea can be widely used to manage the cad electronic files of the enterprise 在此基础上,初步设计了数据库模型和前台访问软件,并采用部分cad电子文件数据在计算机上进行模拟运行,证实了这种方法的可行性和可操作性。该方法进一步完善后可在企业中推广应用,能够有效提高企业cad电子文件管理的管理水平。
