gjb 解釋
軍標
  1. The test quantum is generally small due to the extremely complexity of modern weapon systems, high expenses and long cycle of the tests, which makes the demonstration methods of gjb more difficult to be put into practice

    由於現代武器裝備系統復雜，試驗費用昂貴，且試驗周期長，因而現場試驗的次數往往比較少，而國軍標中的方法需要較多的試驗樣本量，使其在實際工程中難以應用。
  2. The constitutions and principles of position of gps > glonass and beidou navigation system are described all around in this article, and the following technologies are studied and realized : communication between com ports with oop technology, compound navigation with gps and glonass. calculate velocity, pseudorange difference, smoothing pseudorange with the carrier - phase and models to correct error are also done ; the transforms between wgs - 84 and pz - 90, as well as wgs - 84 and beijing54 coordinate system ; the technologies to display and manage bitmap, vector map based on mapx also ; conversion of data formats between gjb and mif data format of maplnfo corp. arithmetic of creation dem data based on contour line data from 1 -. 25000 map data with gjb format. texture the surface of terrains with corrected aviation image

    本文全面介紹了gps 、 glonass 、北斗導航系統的組成、定位原理，研究並實現了面向對象的串口通信技術、 gps + glonass組合導航、測速及偽距差分、相位平滑偽距差分以及有關誤差的模型改正、 wgs ? 84和pz ? 90 、 wgs ? 84和北京54坐標系的坐標轉換、柵格地圖的顯示和管理、基於mapx的矢量地圖的顯示和管理、 1 : 25萬軍標數據和mapinfo的mif數據格式雙向轉換、基於軍標數據的dem生成演算法、基於opengl的三維地形構造、航空圖像紋理地形表面、三維坐標量算、虛擬現實模擬導航、三維地形的層次細化演算法以及數字圖像處理中的圖像增強、幾何變換、影像匹配等技術。
  3. According to the gjb 2077 - 94 and the requirement of automatic radio of haige communication co., a new way of bit synchronization is put forward. this article discusses the design of 8 - fsk modulating and demodulating, signal detection, and fec encoding, based on the technique of bit synchronization. ale module is optimized and mended in its application, because it is a module of automatic radio of the company

    本文根據gjb2077 - 94短波自適應通信系統自動線路建立規程和海格通信公司短波自適應電臺對ale模塊的具體需求，採用了一種新的位同步方法：能量跟蹤法，並在此基礎上提出了8fsk調制解調，信號檢測，前向糾錯編碼的具體實現方法。
  4. Comparing with the model test data the result of the calculation is more close to that from the formula in " design and calculation standard for submarine structure ( gjb ) "

    與實驗數據進行比較，其計算結果比利用gjb 《潛艇結構設計計算規則》的計算結果更接近於真實值。
  5. At the same time, a comparison with united states lrfd code, european ec4 code and china gjb rules has progressed. for guiding engineering practice, the paper arranges different thick steel pipe and different strength concrete and draws a conclusion of the best combination. for the subject of house, the paper studies the form of this kind of special combination beam named flat beam for big space

    本文根據冷彎薄壁方鋼管混凝土柱的特點，探討了方鋼管各板件全截面有效的條件，同時對研究鋼管混凝土較為詳盡的美國lrfd規范、歐洲ec4規范和我國gjb規程做了對比分析；為指導工程實踐，文章對不同壁厚的鋼管和不同強度的混凝土進行了搭配，進行了性價比的比較；結合多層住宅這樣一個研究對象，為獲得大空間，本文探討了扁梁這種特殊的組合梁形式。
  6. Then, according to the requirement analysis, concept design, logic design and database design, the electronic instrument failure rate database was designed and the components failure rates and n factors in gjb / z299b - 98 were established in the database

    其次，按照開發關系型數據庫所要求的需求分析、概念設計、邏輯設計和物理設計四個階段，設計了電子設備失效率數據庫並做了數據錄庫工作。
  7. The maintainability test and evaluation methods in our country are now only confined to the methods of gjb, in which the test quantum and criteria are determined. the tests are carried on according to the test quantum and the observations are used to demonstrate the achievements of weapon systems of the maintainability quantitative requirements specified in contracts, then the decision whether to accept them is made

    目前我國維修性試驗與評定的方法僅僅局限於按照國軍標的方法確定現場試驗樣本量和判決規則，依據所需的試驗樣本量進行現場試驗，根據觀測結果進行維修性驗證，來確定武器裝備的維修性是否達到合同規定的要求，進而確定是否接受該批裝備。
