她們側著身子，在風雪茫茫的田野里掙扎著往前走去，她們盡量利用樹籬遮擋自己，其實，與其說樹籬是可以抵擋風雪的屏障，不如說是過濾風雪的篩子。Single packet filter technology, with its flaws, cannot provide perfect security protection ; intrusion detection, as an active defense system, is a crucial supplementary to the packet technology and work as a second line of defense ; content filter supplies the gap of the information content protection that two former technologies leave and form the last barrier for security protection
單純的包過濾技術由於其自身的缺陷而不能提供完全的安全保護。入侵檢測作為一種主動防禦技術，是包過濾的重要補充，起到了第二道防線的作用。內容過濾彌補了前兩種技術在信息內容防範方面的不足，形成了安全防護的最後一道屏障。A quantitative analysis on the surface of the plate composite membranes with various polymerization tune was made on the basis of the feature absorption to ir by means of attenuated total reflection - fourier transform infrared spectroscopy. the results showed that polyamide functional layer grew thick with the polymerization time going on. this indicates that the polyamide functional layer formed on the interface cannot separate the w / o phases to stop the reaction
利用衰減全反射-傅立葉變換紅外（ ftir - atr ）對不同聚合時間的平板復合膜表面進行了特徵吸收定量分析，研究發現，聚酰胺功能層隨聚合時間不斷增厚，這說明已形成的聚酰胺功能層不能屏障兩相而終止反應，相反由於哌嗪單體的分子量遠低於納濾截留分子量的范圍，很易擴散穿過功能層達到兩相界面，繼續與有機相單體酰氯反應。The special ring - type with three - dimensional depth of a product of function of the products is filtered layer, can stop sand one above 0. 06mm, and is developing into the steady sand cake constantly, form the protective screen of the second dish of sand control, it is particularly remarkable to block sand performance
產品作用本產品特殊的具有立體深度的環狀過濾層，能阻擋0 . 06mm以上的砂粒，並不斷發展成為穩定的砂餅，形成第二道防砂屏障，擋砂性能尤為卓越。After studying many relative books and combining with my own understanding, i write this thesis. this thesis includes : the meaning & characteristics of network security ; threatening & attacking that the computer network faces ; general measures to protect network security ; brief introduction, classification and relationships to network security technology ; general description and key technology of fire proofing ( package filtrate technology, delegating technology, nat technology ) ; the constructive type of fire proofing ( filter route ware, multi - port host computer, host computer screen, subnet screen etc. ) ; the examples of the constructive application of fire proofing ; the future developing trend of fire proofing technology and products, etc. so, net security and fireproof technology are the title of this paper
綜上原因，本文將「網路安全」和「防火墻技術」組在一起形成本論文題目。本論文是筆者在研讀許多相關文獻並結合自己理解基礎上寫成的，主要內容為：網路安全含義及特徵、計算機網路所面臨的威脅和攻擊、保障網路安全的一般措施；網路安全技術的簡介、分類及關系；防火墻概論、防火墻關鍵技術（包過濾技術、代理技術、 nat技術等） ；防火墻的構建類型（過濾路由器、多埠主機、主機屏蔽、子網屏蔽等） ；防火墻的構建應用舉例；防火墻技術的未來發展趨勢及產品等。分享友人
