Firstly , the paper makes an introduction of develop status , deficiency and its background of onc - card - systcm . secondly , cxpatiation is done on the system structure and function requirements of campus one - card - through system , followed by a description of the appropriate database suitable to campus one - card - through system ; thirdly , the paper puts forward an overall plan of campus one - card - through system including the choice of card , the storage of information in the card , the design of network architecture of the system , moreover , the paper studies a software research mode by combining browser / server and client / server . fourthly , the paper explores the distributed database and the method of its establishment , the paper also attaches great importance to the key technology of distributed database , that is , the coherence , the parallel and security of database 本文首先介紹了一卡通系統的研究現狀及課題的選題背景和意義，然后對校園一卡通系統的體系結構、功能需求、采用的數據庫進行了分析；提出了校園一卡通系統的總體方案設計：包括卡的選擇，卡上信息的存儲，系統的網絡結構設計，并探討了一種將b / s和c / s兩種模式相結合作為系統的軟件開發模式；然后探討了校園一卡通系統分布式數據為結構及數據分布策略，闡述了分布式數據庫中一卡通中心數據庫和各子數據庫之間的關系及其建立方法，同時對分布式數據庫中的關鍵技術? ?數據的一致性、并發性和安全性問題進行了討論。
But it is followed by another problem - because it is very difficult for us to find a correct failure detection in asynchronous system such as the internet , the mobile agent fails and recovers later , they all lead to a violation of the exactly - onc e property for the agent ' s execution 但隨之另一個問題又產生了? ?由于在異步的分布式的網絡環境中很難找到一種可靠的故障檢測機制以及陷入故障的移動agent在經過一段時間后又隨時可能恢復正常，所以這都可能會導致對移動agent只執行一次屬性的破壞。
Finally , based on the achievement of onc - sidc processing of sc illustrated above , sc has been processed successfully in the five - coordinate machine center and its profile error has been inspected by use of cmm . the result shows that this technology is correct and economic 最后，基于上述空間凸輪單側面加工理論研究結論，在五坐標加工中心上，成功地加工出了空間凸輪，并應用三坐標鋇l量機對其進行了廓面檢測和誤差計算。
Through the research of open architecture numerical control system ( onc ) at home and abroad , this thesis analysis and contrasts several open modes and system structures of several onc . an pc + motion control card based on onc is proposed 本文通過對國內外數控系統進行研究，分析比較了幾種數控體系結構，提出了pc +控制卡的數控系統組成方式，并系統的研究、開發了運動控制卡。
