Identification cards - recording technique - part 4 : location of read - only magnetic tracks 1 and 2

Then the designation and actualization of a data recorder that would be used in a fighter was introduced in details. also the means used to make the recorder more reliable as well as some features for the sake of anti - jamming and self - correction were depicted. the following part is about the fast programmable flash read - only - memory including its usage and features
接著詳細論述了飛行參數記錄器的設計與實現，分別描述了記錄器的原理組成、硬體結構和軟體流程，還介紹了記錄器採用的各種增加穩定性、抗干擾和糾錯的措施，並詳細敘述了快擦寫可編程只讀存儲器的使用方法。 -
To make it more convenient for users, we design the same graphical interfaces : if only users input main parametric data of a standard part, automatically the data will be got by the data - input module ; the data stored in database of the server will be read through the data - processing module ; then they will be sent to the standard part maker module, in which solidworks will build standard parto since the latest data accessing technique - ado is adopted in our data - processing module, it becomes true to get and apply data through intranet
標準件生成用到的參數化數據和圖形界面中顯示的數據全部存儲在服務器數據庫中，數據庫管理系統軟體使用的是sqlsserver7 . 0 。我們設計了統一的圖形界面，方便用戶的使用，用戶只需要輸入主參數，然後由數據輸入模塊獲取用戶的輸入，通過數據處理模塊讀取存儲在服務器數據庫中的數據，並把數據傳遞給標準件生成模塊，在solidworks中生成標準件。數據處理模塊採用了現在最新使用的數據訪問技術ado ，實現數據在intranet上的傳遞和應用。 -
As the application of distributed computing is used much more widely ， distributed database becomes a significant part of information management it avoids a lot of disadvantages of conventional centralized database ， and is applicable to many situations distributed database is a set of data which is the unity logic ， but in fact these data is located on different sites it is of high availability ， easy expansibility ， high concurrency ， high efficiency and etc in distributed system ， data redundancy is a method to improve the speed of query and the availability of system distributed query should shield the lower level details of data redundancy from end users ， distributed transaction should ensure data from disaccord this paper introduces basic conceptions of distributed database firstly ， discusses distributed transaction and concurrent control ， describes the development prototype mysql ’ s characters ， architecture and executive mechanism ， then shows the skeleton model of dpsql and exposes the strategy and algorithm of distributed query and distributed transaction ， at last analyzes the extra expenses and response delay of distributed processes this paper exposes the implementation mechanism of distributed query and distributed transaction emphatically distributed query uses the strategy of “ read one ， write a11 ” s0 in such a system if user ’ s requests are read - - only for the most part and the distribution of data redundancy is plausible ， efficiency is very high distributed transaction uses two - 。 phase commit protocol to ensure the consistency of global data ， which has less communication overhead
分散式查詢需要向用戶屏蔽數據冗餘分散的底層細節，分散式事務處理要保證全局數據完整，這都是傳統集中式數據庫不曾面臨的問題。本文首先介紹了分散式數據庫的概念性問題；接著討論了分散式事務涉及的定義及演算法；然後描述了dpsql的原型mysql的特性、結構和執行機制；繼而給出了dpsql的梗概模型，闡述了實現分散式查詢和分散式事務處理的策略及演算法；最後分析了進行分散式處理給系統增加的額外開銷和客戶端的額外響應延遲。本文重點描述了分散式查詢和分散式事務處理的實現機制，分散式查詢採用」讀一個寫全部」的本地優先策略，在讀操作頻繁的系統中，只要庫的分佈合理，單機效率極高，幾乎無任何附加開銷和延遲，而以整個系統的角度看來，吞吐量就更是優于單機系統；分散式事務處理採用兩階段提交協議，通信次數較少並能確實保證副本一致。
