In chapter one, we ' ve briefly introduced field bus, the advanced industrial control network. contrapose to the problems exsist in field bus, we ' ve discussed the application and status of industrial ethernet in chapter two. combined with the development of ethernet, in chapter three, we ' ve brought forward a kind of ethernet structure and a design project for ethernet controller, the key equipment in ethernet. we ' ve also analysed how to resolve the uncertainty of the traditional ethernet which affected its industrial application. in chapter four we ' ve talked about how to realize network management system based on snmp and web technology, which includes its structure, function and programming model. we ' ve discussed the technology of ethernet integrating with other network in chapter five, which consisted of both integrating with information network and control network. in the last chapter we ' ve analyzed the application project of ethernet in control field through practical case
第三章結合以太網技術的發展提出了一種以太控制網路的
體系結構和其中的關鍵設備? ?
嵌入式以太網控制器的設計方案,還對傳統以太網中影響其在工業控制上應用的「非確定性」問題的解決辦法作了分析。第四章討論了基於snmp協議和web技術的網路管理系統的實現,包括結構、功能和編程模型。第五章討論了工業以太網和其他網路的集成技術,分為與信息網路和控制網路集成兩方面,最後一章通過實例來分析以太網在控制領域的應用方案。
These thin films exhibit physical properties different from those bulk crystals and per molecule. in particular, when some functional biomolecule was imbedded by way of covalence or noncovalence on the surface of the films, the films have many functions of biological membrane. these functions made supramolecular assembly technology have important application prospects
這種技術能夠賦予該有機分子既有別于
體材料又不同於單個分子的性質,特別是當在分子薄膜表面以共價或非共價的方式
嵌入某種功能性的生物分子時,這種薄膜就會具有仿生膜的功能,這種功能使得超分子組裝技術在生物傳感器領域具有重要的應用前景。
Built on the solid, tested xiiiiplus platform, the r110xifor four - inch labels - offers an unprecedented level of on - demand printing flexibility in tag placement as well as unique features such as xml for seamless integration into enterprise systems, automatic calibration, flexible inlay positioning, multiple power levels, statistics tracking, easier rfid programming and more detailed information through the front panel display
R110xi r170xi印表機編碼器可以提供一秕列豐富的功能包括自動校準多種功率設置和靈活的
嵌體放置這些功能對于目前主要的rfid應用而言是必需的。
The mutation, contrast and heterogeneity of ecological interface between oasis and desert ecosystem increased. rare natural or non - regional mosaic of patch show obvious sensitivity to spatial scale, the change ratios of theirs area and perimeter are greater than large patch
同時通過測度敏感性檢驗,表明在尺度變換中,稀少的自然或隱域性斑塊鑲
嵌體對空間尺度敏感性大,面積、周長等變化率大於大斑塊,隨尺度中度干擾則合併成較大的斑塊,隨尺度強烈干擾或隔離加強后最先消失。
