The characteristics of tm - 22 expression presented in transgenic tobacco : 1 ). virus specificity in either homozygote or heterozygote ; 2 ) tm - 22 gene integrated in tobacco genomic dna with single copy and in inheritance and segregation to progenies on the mendel role ; 3 ). transgenic line with tm - 22 promoter ( ptm47 ) showed infected symptoms with cell death distinguished to one with 35s promoter ( ptm49 ) after inoculation with tomv - 2a
其次，通過氨基酸序列和結構的比較，確定tm - 2 ~ 2基因的編碼蛋白與tomv病毒在抗病反應中相互識別的特異氨基酸及其功能；然後，應用重組dna技術，互換tm - 2 ~ 2基因和tm - 2基因的對應結構域，構建嵌合基因，獲得嵌合蛋白表達的轉化體，驗證tm - 2 ~ 2編碼蛋白中變異氨基酸的作用。Thispaperhasstudiedonthedatalinkinterfacetechniqueoftacticalcontrolsystem. firstof all, functional requirement and the important role of data link interface in tactical controlsystem is introduced ; secondly, with object oriented method, the characteristic of uav taskcontrol process is analysed, and then uav task control information model is established, anddata link interface standard of tactical control system is designed based on this model, including message format and transmission mechanism ; thirdly, data link control module isdesigned based on embedded linux operating system and has realized conversion betweendata link standard interface and the private interface of uav data link ; and then, combinationreal time corba middleware and its event channel, data link control modular componenttechnology is studied, and realization scheme is put forward ; finally, demostration is madebased on prototype of tactical controlsystem, which verify the validaty of data link interfacestandardandembeddeddatalinkcontrolmodules
本文對戰術控制系統中的數據鏈介面技術進行研究:分析了數據鏈介面在戰術控制系統中的功能需求;採用面向對象的方法，分析無人機任務控制問題，建立了無人機任務控制信息模型，並基於該模型設計了數據鏈介面通信協議，包括報文格式和傳輸機制;基於嵌入式linux系統設計了數據鏈介面控制模塊，實現了數據鏈標準介面與無人機數據鏈私有介面之間的相互轉換;結合實時corba中間件及其事件通道，研究了數據鏈介面控制模塊組件技術，並給出了實現方案;通過戰術控制原理實驗系統的演示實驗，驗證了數據鏈介面通信協議和嵌入式數據鏈介面控制模塊的有效性。But traditional fieldbus has been widly used in factory field and will act an important part for a long time, so it is necessary that to realize fieldbus connect to office network, make it has the capability of inter - connection and inter - operation, and keep it ’ s architecture unchanged. the paper discusses a method to slove the problem. that is making use of ethernet / ip protocol which is one of industrial ethernet protocols, to design an embedded fieldbus gateway. the gateway mainly consists of s3c2410, a 32bit high performance microprocessor based on arm core, to realize interconnection devicenet network, controlnet to ethernet
本文提出利用高性能、低功耗32位risc結構的arm處理器與armlinux嵌入式操作系統相結合，並利用ethernet / ip工業以太網協議構造嵌入式網關，實現設備的現場總線與企業信息網路無縫鏈接，並保證了devicenet和controlnet兩種網路的互操作性，構建一個可跨地域共享、便於實現高層次集中管理、監控和決策的新型嵌入式實時在線監控網路。Keywords : network governance, structural embeddedness, interactive mechanism, integrated mechanism, coordination, safeguard
關鍵詞：網路治理，結構嵌入，互動機制，整合機制，協調，維護。The authentication is done using standard token sharing protocol of gss ( generic security service ) while authorization is done by simply looking for the client ' s dn in the database, then return a limited proxy certificate, which embeds the security policies relating with the requesting user in the virtual organization. ldap stores contents about certificate authority, object policy and locality information and so on. aces enhances the resource severs and enables them to recognize the access control policies embedded in the proxy certificates, and implements the fine - grained access control through combining its own policies with
訪問控制決策子系統接受它所管轄的虛擬域內用戶的請求，利用gss （ genericsecurityservice ）標準令牌交換協議相互驗證身份后，通過查詢數據庫得到用戶相關的授權策略，並把授權策略寫入到代理證書中，返回給請求用戶; ldap目錄服務器儲存了ca證書、資源策略和位置信息等;訪問控制實施子系統通過對應用程序授權部分進行擴展，使其支持嵌入在代理證書中的授權策略，並結合本地的安全策略做出最終決策。分享友人
