The product cycle is composed of two main processes:the design process and the manufacturing process3. The activities involved in the design process can be classified largely as two types:synthesis and analysis4. Rapid prototyping is becoming popular because this technology enables the construction of a prototype by deposition layers from the bottom to the top 5. This includes the preparation of drawings,reports,and bills of materials.III1.d 2.e 3.b 4.j 5.i 6.c 7.f 8.h 9.g 10.aIV1.處理速度 2.用戶友好的交互圖形 3. 產(chǎn)品周期 4. 設(shè)計規(guī)格 5. 設(shè)計評價6.CAD 7.CAM 8.CAE 9.design process 10.production processV1. 除非能以較低的價格提供更好的質(zhì)量及更短的交貨時間提供新產(chǎn)品,否則任何企業(yè)都無法在當今的國際競爭中立足。2. 設(shè)計過程始于由市場人員認定的用戶需求,止于對產(chǎn)品的完整描述,通常用圖形來表現(xiàn)。3. 例如:尺寸縮小表示一張薄的材料由具有厚度屬性的等效曲面來代表,或一個細長區(qū)域由具有截面特性的線段來表示。4. 如圖10-1所示,制造過程根據(jù)設(shè)計過程的圖紙始于工藝計劃,止于實際的產(chǎn)品。5. 首先要導出一個分析模型,因為分析子過程適用于該模型而非設(shè)計本身。 VI. 1. Thus,to understand the role of CAD,CAM,and CAE,we need to examine the various activities and functions that must be accomplished in the design and manufacture of a product2. As illustrated in Fig. 10-1,the initial design activities(such as identification of thedesign need,formulation of design specifications,feasibility study with collectingrelevant design information,and design conceptualization)are part of the synthesis subprocess3. Once the conceptual design has been developed,the analysis subprocess begins with analysis and optimization of the design4. This technology enables the construction of a prototype by deposition layers from the bottom to the topThus it enables the construction of the prototype directly from its design because it requires basically the cross-sectional data of the product5. Once process planning has been completed,the actual product is produced and inspected against quality requirementsParts that pass the quality control inspection are assembled,functionally tested,packaged,labeled,and shipped to customersPart 4 Reading B. 1.

Reading B 遠程管理特洛伊木馬(RAT)病毒 惡意軟件的世界常常分成兩類:病毒性和非病毒性。病毒是埋藏在其他程序中的很短的程序代碼。當“主”程序執(zhí)行時,病毒就復制自身,并企圖做些有破壞性的事。在此過程中,它們的行為很像生物病毒。 蠕蟲是一類計算機寄生蟲,可以把它們歸到病毒陣營,因為它們進行復制,從一臺計算機散布到另一臺計算機。 作為病毒,蠕蟲的有害行為常常只是復制這個行為。它們通過生成大量的電子郵件或申請連接的請求,使服務器沒法處理而導致計算機崩潰。 但蠕蟲也有別于病毒,它們不是存在于其他文件中的代碼。它們可以是整個文件,如Excel數(shù)據(jù)表格。它們不需要運行另一個程序就進行復制。 遠程管理(病毒)是另一類非病毒性惡意軟件特洛伊木馬(或更簡單地稱作木馬)的例子。這些程序的目的不是復制,而是滲透進去加以控制。它們偽裝成某種東西,但實際上是另一件東西,通常具有破壞性。 有多種類型的木馬病毒,其中包括間諜機器人(它在網(wǎng)站上報告計算機用戶來訪)和擊鍵機器人(它記錄和報告用戶的擊鍵,目的是為了發(fā)現(xiàn)口令和其他的保密信息)。 RAT病毒企圖讓遠程入侵者對受感染的計算機進行管理控制。它們以客戶機/服務器那樣的方式進行工作。服務器駐留在受感染的機器中,而客戶機位于網(wǎng)絡(luò)上能實施遠程入侵的其他地方。 利用標準的TCP/IP或UDP協(xié)議,該客戶機給服務器發(fā)送指令。服務器在受感染的計算機上做被告知的事情。 木馬病毒,含RAT病毒,通常由用戶、甚至最聰明的用戶不經(jīng)意地下載下來。訪問惡意的網(wǎng)站或者點擊惡意的鏈接都可能招致不想要的特洛伊病毒進入(計算機)。RAT病毒利用普通程序和瀏覽器中的弱點自行安裝。 一旦它們駐留在計算機中,RAT病毒是很難發(fā)現(xiàn)和去除的。對于Windows用戶,簡單地擊打CtrlAltDelete鍵并不能暴露RAT病毒,因為它們在后臺工作,不會出現(xiàn)在任務列表中。 有些非常窮兇極惡的RAT病毒設(shè)計成以一種即使在被發(fā)現(xiàn)后也非常難去除的方式安裝。 例如,Back Orifice RAT病毒的一個變種,叫G_Door,安裝其服務器作為Windows系統(tǒng)目錄中的Kernel32.exe,存活并鎖定在那里并控制注冊鍵。 活動的Kernel32.exe是不能去除的,重新啟動也不能清除注冊鍵。每次受感染的計算機開機,Kernel32.exe被再次啟動,并被激活和鎖定。 有些RAT病毒對已知的或標準的端口進行偵聽。其他的則對隨機的端口進行偵聽,通告它的客戶機,電子郵件連接到了哪些端口和哪些IP地址。 通過ISP(因特網(wǎng)服務提供商)連接到因特網(wǎng)上的計算機,雖然常常被認為比靜態(tài)的寬帶連接更安全,也可能被這樣的RAT病毒所控制。 RAT病毒服務器這種激活連接的能力,也能讓它們中的一些可以入侵防火墻。通常向外的連接是允許的,一旦服務器與客戶機建立聯(lián)系,客戶機和服務器就能進行通信,服務器就開始遵循客戶機的指令工作。 出于各種原因,系統(tǒng)管理員使用合法工具管理網(wǎng)絡(luò),如記錄雇員的使用和下載程序更新(與某些遠程管理木馬病毒的功能非常相像)。這兩者間的差別可能是非常小的,遠程管理工具被入侵者使用就成了RAT病毒。 2001年4月,一名叫Gary McKin-non的失業(yè)的英國系統(tǒng)管理員利用合法的遠程管理工具Remotely Anywhere成功地控制了美國海軍網(wǎng)絡(luò)上的多臺計算機。 McKinnon通過黑客手段獲得目標計算機上未防護的口令和使用非法拷貝的Remotely Anywhere軟件,突破了美國海軍的網(wǎng)絡(luò),利用該遠程管理工具偷竊信息、刪除文件和記錄。McKinnon從他女朋友的電子郵件賬號發(fā)起攻擊,這個賬號給偵查留下了線索。 一些有名的RAT病毒是Back Orifice的變種,如Netbus、SubSeven、 Bionet 和Hackatack。這些RAT病毒大多是一組程序,而不是單獨的一個程序。黑客把它們變成一個龐大的、具有類似功能的木馬病毒陣列。 Unit 6 練習答案及課文譯文Part 2Reading AI. 1.
