Moreover , the thesis discussed the inevitability and feasibility of three - layer system architecture based on b / s ( browser / server ) mode , also proposed some problems and related resolutions are given , they are good references for other similar system design and engineering practical application 此外,還探討了基于b s三層結(jié)構(gòu)模式開發(fā)web化程序的必要性和可行性,提出了在實際開發(fā)過程中遇到的一些問題及相應(yīng)的解決方案,其中的部分設(shè)計思想對今后類似系統(tǒng)的設(shè)計及工程實際應(yīng)用具有可借鑒之處。
The design of the whole system adopts the three - layer system that integrates the c / s and the b / s structures . the enterprise management information system based on multi - agent is introduced . the communication between client and server and the communication among sub information units are all achieved by " communication agent " 系統(tǒng)總體方案的設(shè)計采用c / s和b / s相結(jié)合的三層體系結(jié)構(gòu),提出基于多A gent技術(shù)的企業(yè)管理信息系統(tǒng),用戶同服務(wù)器的通訊以及服務(wù)器同各子信息部件的通訊都通過“通訊agent ”來實現(xiàn)。
A three - layer system frame according with j2ee standard was adopted in system structure and oracle was used as basic network database of system , so that the data can be saved safely and searched with high speed . this system has such basic pdm functions as project management , human resource management , right management , product configuration management , etc . and , it was applied to a certain extent in enterprises 系統(tǒng)體系結(jié)構(gòu)采用了符合j2ee標(biāo)準(zhǔn)的三層系統(tǒng)架構(gòu),使用oracle作為系統(tǒng)的底層網(wǎng)絡(luò)數(shù)據(jù)倉庫,實現(xiàn)了數(shù)據(jù)的安全存儲和高速查詢,該系統(tǒng)具備了項目管理,人員管理,權(quán)限管理,產(chǎn)品配置管理,版本管理等基本的產(chǎn)品數(shù)據(jù)管理功能,并在企業(yè)獲得一定程度的應(yīng)用。
Abstract : to facilitate the design , teaching and research of asphalt pavements , the article founded the models of displacement and tensile stress of three - layer system by using separation of variables , analysis and synthesizer . based on the analysis of common pavement structures and their equivalent conversion , the regression formulas of displacement and tensile stress are obtained successfully , furthermore the formulas applied in multi - layer system are checked . a great number of results of regression formulas show good accuracy for engineering application and theory research 文摘:為方便瀝青路面結(jié)構(gòu)設(shè)計生產(chǎn)、教學(xué)、科研之用,本文采用分析綜合法與分離變量法建立了彈性三層體系應(yīng)力位移顯式模型;并在分析常見路面結(jié)構(gòu)層厚度及其當(dāng)量換算和模量變化范圍的基礎(chǔ)上,成功求得了三層體系路表彎沉、上層滑動應(yīng)力、上層連續(xù)應(yīng)力、中層應(yīng)力逼近公式;精度分析表明本文逼近公式精度很好,完全可推廣應(yīng)用于多層體系,滿足工程設(shè)計和有關(guān)理論研究的需要
According to the prospecting correlation standard classification method , based on the combination of windows nt server , iis5 . x , asp . net and oracle 9i , the article introduces how to design the correlation standard information classification search system for daqing oilfield prospecting with three - layer system structure of the b / s mode using visual c # . net , dreamweaver and other softwares . using the accurate or fuzzy search method , table looking up and other search method , the search system studied in this article can be used to search standard numbers , standard names and stamdard system structure of the prospecting correlation standards . with com add - in built using visual c # . net , it realizes office browsing through web pages 以windowsntserver + iis5 . x + asp . net + oracle9i的組合為技術(shù)支撐,根據(jù)勘探相關(guān)標(biāo)準(zhǔn)分類方法,結(jié)合visualc # . net 、 dreamweaver等軟件,采用b / s模式三層體系結(jié)構(gòu),設(shè)計了大慶油田勘探相關(guān)標(biāo)準(zhǔn)信息分類查詢系統(tǒng);利用精確或模糊及體系表等查詢方法實現(xiàn)了勘探相關(guān)標(biāo)準(zhǔn)的標(biāo)準(zhǔn)號、標(biāo)準(zhǔn)名稱查詢及體系標(biāo)準(zhǔn)結(jié)構(gòu)查詢,利用visualc # . net建立comadd - in ,實現(xiàn)web上的office瀏覽。
