In each area, three potential sites were identified following a constraint mapping process, and for each of the total of six sites, two disposal options were considered, cad and cdf 在地圖上標(biāo)示所有限制后,研究在上述每區(qū)鑒別了三個(gè)有潛質(zhì)的選址并且在六個(gè)選址各自考慮了兩個(gè)卸置方案,即
Method permissions map security roles to specific ejb methods and security constraints map security roles to web resource collections that are a combination of http methods and url patterns 方法權(quán)限將安全性角色映射到特定的ejb方法而安全性約束則將安全性角色映射到web資源集合中,這些web資源集合是http方法和url模式的一個(gè)組合。
Chapter 3 investigates the content and major form classes of assembly constraint with description of semantics, bringing forth semantics " being decomposed and constraint mapping in order to turn semantics delegating of abstract and generalization engineering knowledge into geometric constraint 第三章通過(guò)對(duì)裝配語(yǔ)義進(jìn)行合理的約束描述,研究了裝配約束的具體內(nèi)容及其特點(diǎn)和主要類(lèi)別,提出了裝配語(yǔ)義的分解與裝配約束映射的建立,以便于將面向裝配的工程知識(shí)和經(jīng)驗(yàn)抽象與概括的產(chǎn)品裝配語(yǔ)義是轉(zhuǎn)化為系統(tǒng)所能理解具體的幾何約束。
This dissertation studies the virtual assembly technology, presenting a product-assembly-design theory and method based of semantics in vrml environment . great progress has been made in the research of the key techniques of virtual assembly, which includes the assembly model layer level representation, abstracting the commonly assembly semantics, semantics decomposition and constraint mapping, semantics driving 本文研究了虛擬環(huán)境下的裝配技術(shù),提出了在vrml環(huán)境下基于語(yǔ)義的產(chǎn)品裝配設(shè)計(jì)技術(shù)理論與方法,對(duì)虛擬環(huán)境中裝配模型的層次表達(dá)、常用裝配語(yǔ)義的提取、裝配語(yǔ)義的分解與裝配約束的映射、裝配語(yǔ)義的驅(qū)動(dòng)等關(guān)鍵技術(shù)進(jìn)行了研究。
