For example, the administratively monopolized access regulation that caused the upper section ( railway network operation ) and lower section ( the transportation businesses ) integrated ; the relatively closed investment mechanism that at first mainly depended on government allocation, then mainly relied on railway ' s building fund ; the price regulation that controls the right of price setting strictly and keeps a low price level for a long time ; the income distribution regulation that with its income and expense carried out in two separate ways ; finally, the regulation framework that with the roles wrongly arranged and with inadequate supervision and lagged legislation
由此可以看出，我國鐵路規制體制的計劃經濟痕跡非常明顯：在進入上，實行「上下一體」的行政性壟斷；在投資上，實行先以國家為主而後以鐵路建設基金為主的相對封閉的投資體制；在運價上，國家嚴格控制定價權，並長期以來保持低價位；在收益分配上，實行收支兩條線的清算制度；最後，在規制的組織架構方面，不僅角色錯位，而且缺乏監督，立法滯后。 -
On core service, we implement an access control strategy based on role, digital signature and encryption / decryption of soap message by using usbkey hardware, stateful web service through extending simple object access protocol ( soap ), and a kind of log management based on rank. on transport adaptering, we implement mechanisms for priority - based transmitting and rules - based transmitting, and implement a transport adapter based on http request / response model. finally, on service adaptering, we discuss two service wrapper mechanisms : runtime wrapper mechanism and factory method wrapper mechanism, which can be used to encapsulate difference of various web service containers, and implement a service adapter
在核心服務方面，通過擴展簡單對象訪問協議（ simpleobjectaccessprotocol ， soap ）實現有狀態的web服務，然後討論了基於角色的訪問控制與基於usbkey盤的soap消息的數字簽名與加密的實現、基於分級的日誌處理模型的實現;在傳輸適配方面，實現了基於優先級和基於規則的消息轉發機制，實現了基於http請求/響應模型的傳輸適配器;在服務適配方面，討論了兩種服務的封裝機制:運行時封裝機制與工廠方法封裝機制，結合這兩種機制並對服務適配器做了實現。 -
Previous works demonstrate two significant disadvantages : 1 ) the context access interface is procedural, which means the application should be aware of the arrangement of the context data storage. 2 ) the context reasoning mechanism is more or less ad - hoc, especially in the case of reasoning with the uncertainty in the context
目前提出的若干實現方案存在兩個主要不足： 1 ）查詢介面過程化（ procedural ） ，應用需要知道上下文信息存儲、分佈的具體細節； 2 ）對上下文推理問題、尤其是不確定性上下文推理問題在上下文服務中的實現方法沒有給出有嚴格理論基礎的說明。 -
The two phases will require the development of various security procedures for flight deck access and additional procedures in the event of emergency evacuation. subsequent to the meeting, cad issued a new flight operations notice which defined the latest faa regulations regarding the strengthening and locking of the cockpit door on all passenger aircraft flying into the usa, and further mandated the cad locked cockpit door procedures, including requiring the door locking mechanism to be secure to the extent that tempering with the lock or door handle from the passenger cabin does not unlock the door
在會議過后，民航處發出新的飛行運作通告，就美國聯邦航空局關于所有飛往美國的客機駕駛艙門必須鎖好和令艙門更為鞏固的最新規則，作出闡釋；並且進一步就民航處規定關鎖駕駛艙艙門的程序發出指令，其中包括規定艙門的關閉裝置必須鞏固，即使有人從客艙內破壞駕駛艙的門鎖或把手，也不會令駕駛艙的門開啟。 -
Main contents of this thesis include following parts : firstly the frame format and frame type in 802. 11b are summarized. two mac layer access methods : dcf ( distributed control function ) and pcf ( point control function ) are deeply analyzed. physical layer, management entity and security mechanism are generally narrated
全文內容主要包括以下幾部分：第一部分總結了802 . 11b協議中的mac層幀結構和幀類型，較深入地分析了mac層的pcf （中心網控方式）和dcf （分散式接入方式）兩種接入方式，概述了物理層、管理實體和安全機制。
