reusable engine 中文意思是什麼
reusable engine
解釋
可再次使用的發動機-
Both advantages of rocket engine and air - breathing engine are integrated into one kind of propulsion system, called rocket - based - combined - cycle ( rbcc ), which has multiple operating woke modes, including ejecting, subsonic combustion, supersonic combustion and rocket mode, with each mode operating at varying flying stage. rbcc has prominent potential of high efficiency and low cost, and so it is recognized as an advanced propulsion system of future single - stage - to - orbit reusable spacecraft and hipper - sonic missile. it has been broadly investigated in foreign countries and has been progressed into small and full - scale flying stage
火箭基組合動力循環（ rbcc ， rocketbasedcombinedcycle ）將傳統的火箭發動機和吸氣式發動機的優點集中組合到一個具有多種工作模態（包括引射、亞燃、超燃及火箭模態）的發動機里，在不同的飛行階段啟用不同的工作模態，因此具有大幅提高航天推進系統經濟性與高效性的潛在優勢，並可能發展成為下一代單級可重復使用航天器以及高超聲速導彈武器的動力系統。 -
Enterprise information system framework provides a series of reusable groupware, such as persistence layer which introduces dynamic value object 、 value list hander and command pattern, it encapsulates the detail of accessing database and affords the interface of different persistence layer framework ; basing on asynchronous javascript and xml ( ajax for short ), we develops the client validity check engine 、 dynamic cascading menu and common 、 dynamic tree structure groupware, as well as a set of tag library which include query 、 pagination 、 cache an so on. they reduce the code redundancy and predigests the development of interface layer enormously ; the security subsystem which is based on secure socket layer ( ssl for short ) and role - based access control ( rbac for short ) ensures the data security transmission and privilege control. furthermore, the model of enterprise application integration ( eai for short ) which based on web services, it supply some helpful explore for the sake of system integration and data communion for the future
企業信息系統框架提供了一系列可復用組件，例如採用動態vo 、值列表處理器以及命令模式的持久層組件，封裝了數據庫訪問細節，並為不同的持久層框架提供調用介面;基於ajax （ asynchronousjavascriptandxml ）技術的客戶端校驗引擎、動態級聯菜單以及通用動態樹型結構組件，一系列查詢、分頁、緩存等標簽庫則減少了表示層的代碼冗餘，簡化了表示層開發;基於ssl登錄以及基於角色的訪問控制的安全子系統則初步實現了數據安全傳輸和權限控制;此外基於web服務的企業應用集成模型為今後系統集成、數據共享提供了有益探索。
