Based on the data of the detailed land use investigation in 2003 and adopting the quantified structure analysis method of landscape ecology , this paper analyzes the regional differences in land use structure and the causal factors in qionglai city , sichuan province , and puts forward suggestions of regulating regional land use structure so as to achieve the purpose of efficient and reasonable utilization of land 摘要根據(jù)2003年土地利用詳查變更資料庫中的數(shù)據(jù),采用景觀生態(tài)學(xué)結(jié)構(gòu)定量分析方法,對邛崍市土地利用結(jié)構(gòu)的區(qū)域差異及其成因進(jìn)行分析,并提出調(diào)整區(qū)域土地利用結(jié)構(gòu)的建議,以達(dá)到土地的高效、合理利用的目的。
In development and the research of tai steel estate company ' s equipment management information system , according to the viewpoint of information theory , the concept of equipment information have determined , the equipment information of company has carried out overall investigation , the computer transformation way of information have analysed through applying the scientific method of data process and systems analysis and confired , dassifed and described for systematic in formation ; . on this foundation , with the theoretical foundation of information theory and set theory to guide , equipment management information system have carried out overall research through structured analysis method , systematic overall structural model and system to design model have established ; tai gang estate company ' s equipment management information system has maked through the aid of this database development tool of visual foxpro software as well as built - in to use technology again ofthis 2 kinds software of word and excel 在太鋼房產(chǎn)公司設(shè)備管理信息系統(tǒng)的研究與開發(fā)中,依據(jù)信息論的觀點(diǎn),確定了設(shè)備信息的概念,對公司的設(shè)備信息進(jìn)行了全面的調(diào)查,通過應(yīng)用數(shù)據(jù)流程和系統(tǒng)分析的科學(xué)方法,對系統(tǒng)信息進(jìn)行了確認(rèn)、分類和描述,并分析了信息的計(jì)算機(jī)轉(zhuǎn)化方式;在此基礎(chǔ)上,以信息論、集合論的理論基礎(chǔ)為指導(dǎo),通過結(jié)構(gòu)化的分析方法,對設(shè)備管理信息系統(tǒng)進(jìn)行了全面研究,建立了系統(tǒng)總體結(jié)構(gòu)模型和系統(tǒng)設(shè)計(jì)模型;借助visualfoxpro這一數(shù)據(jù)庫開發(fā)工具以及成熟的excel和word這二種軟件,通過軟件嵌入復(fù)用技術(shù),開發(fā)出太鋼房產(chǎn)公司設(shè)備管理信息系統(tǒng)。
In experiment the control object is boiler , and the designed fuzzy controller is used to control the real - time system . the effect of the simulation and real - time control is better , which proves good characters and the correctness of the structure analysis of the designed controller , and also manifests that using the structure analysis method can direct the design of fuzzy controller and supply the theory basis 選擇實(shí)驗(yàn)裝置中鍋爐為控制對象,將本文中提出的具有等比間距隸屬函數(shù)的模糊控制器組成控制系統(tǒng)對鍋爐水溫進(jìn)行溫度實(shí)時(shí)控制,仿真和實(shí)時(shí)控制實(shí)驗(yàn)均取得了良好的控制效果,由此證明該控制器的優(yōu)越性,同時(shí)也證明解析結(jié)構(gòu)分析結(jié)果的正確性,這表明運(yùn)用模糊控制器的解析結(jié)構(gòu)分析可以指導(dǎo)完成模糊控制器的設(shè)計(jì),并為其提供理論基礎(chǔ)。
It also combines structured analysis method and object oriented analysis methods of software engineering to conduct system modeling , static and dynamic uml ( unified modeling language ) analysis and constructing work . by utilizing the large object of oracle and vrml ( virtual reality modeling language ) , it solved the problem of three dimension interacting of graphics . conclusively this system provides a transparent , efficient and convenient platform to users who collaborate with each other in an engineering project 系統(tǒng)使用oracle的大數(shù)據(jù)存儲支持和虛擬現(xiàn)實(shí)建模語言vrml ( virtualrealitymodelinglanguage )較好的解決了三維圖形交互的問題,能為用戶提供一個(gè)安全、快捷、處理透明、功能強(qiáng)大的用戶協(xié)同工作平臺,提高了cad設(shè)計(jì)用戶的產(chǎn)品設(shè)計(jì)效率和產(chǎn)品設(shè)計(jì)水平。
