本文在已有理論研究的基礎上,針對預應力混凝土橋梁建設及使用中存在的影響結構耐久性的實際問題,綜合運用電化學理論、概率理論、結構可靠性理論、混凝土和預應力混凝土結構基本理論、結構優化理論及控制維修決策等理論和方法,詳細研究了基於電化學理論的鋼筋銹蝕檢測方法、預應力混凝土橋梁結構的腐蝕損傷模型、可靠性分析、基於腐蝕控制的維修方法、橋梁結構方案選型及優化設計以及在役橋梁結構的優化維修決策等問題第二章混凝土結構的腐蝕機理及檢測技術目前普遍認為,結構混凝土中鋼筋的腐蝕是一種電化學的過程,包括在金屬表面形成陽極(腐蝕)和陰極(鈍化)區域以及不同區域間的電位差等。Circuit design is the basis of design of demultiplexer. speed, power and chip area are the main factors that should be considered in circuit design. every circuit structure has its merits and drawbacks, e. g. cmos logic family has a slower speed, but lower power, smaller area, scfl ( source couple fet logic ) family has a higher speed, but higher power, larger area. we should choose a proper circuit structure or their mixed structure for certain design to get a good tradeoff among the three factors. flip - flop is the fundamental element of demultiplexer, setup time and hold up time are key factors, which influence the speed of circuit, thus the design aim is how to reduce them. in this thesis we place emphasis on the design of scfl latches
速度、功耗、面積是電路設計要考慮的主要因素,不同的電路形式具有不同的優缺點,如cmos互補邏輯電路功耗低,面積小,速度相對較慢; scfl (源極耦合fet邏輯)電路速度高,功耗和面積較大。所以要針對具體設計需要選用適當的電路形式或其組合結構,以滿足設計要求。觸發器是分接器的基本組成單元,建立時間和保持時間是影響電路速度的關鍵,所以減小建立時間和保持時間是觸發器設計的主要目標,本文著重介紹了scfl鎖存器的設計和優化方法。Anti - igg antibody was immobilized onto the surface of gold electrode modified with a thin layer of protein a. biotin labeled anti - igg antibody and hrp - streptavidin were premixed to form network complex to be used as probes for amplifying the sensing response of antibody - antigen interaction
