    首先從環境試驗的組織結構入手，研究適合環境試驗發展的組織結構，提出將原來的直線制組織結構轉變為直線職能制和矩陣制相結合的組織結構，並探討在這種結構下的人力資源管理和績效考評、提出適應目前軍用裝備發展要求的環境試驗組織機構與人力資源管理體系；然後從環境試驗過程管理的角度出發，運用排隊論的有關概念，合理解決試驗排序，使產品在實驗室的停留時間最短，並建立試驗過程管理與控制體系；從試驗信息的重要性角度出發，探討試驗信息收集與反饋的一般方法及建立環境試驗數據信息庫的重要性；最後從質量管理的角度出發，研究環境試驗內部質量保證部門的作用與職能，運用服務質量環的原理構建了環境試驗的質量保證體系。
  4. The proposed md mesh - based motion coding methodis then combined with the pairwise correlating transform, and acomplete md video coding scheme is proposed. further measures are takento reduce the mismatch between the encoder and decoder that occurs whenonly one description is received and the decoder reconstruction isdifferent from the encoder. the performance of the proposed scheme isevaluated using computer simulations, and the results show, compared toreibman s md transform coding mdtc method, the proposed schemeachieves better redundancy rate distortion performance

    數據重傳必然會引起延遲，因而在需要很短延遲的應用中是行不通的，如雙向無線通信同時在以廣播方式進行數據傳輸時也是行不通的當有大量突發錯誤時，糾錯碼如分組糾錯碼block code及卷積碼convolutional code無法在不產生額外延遲及需要額外運算的前提下對數據提供足夠的保護而錯誤掩蔽的性能則受接收到數據與丟失數據之間的殘留相關性大小的影響。
  5. Abstract : the physical significances of the reaching law parameters and the qualitative relationships among them in variable structure control ( vsc ) are analyzed. according to the relationships, a reaching law control method is put forward based on fuzzy rules. to improve control quality, the reaching law parameters are selected by fuzzy rules. the control scheme presented in this paper not only preserves the advantages of traditional reaching law control, that is, insensitivity to any variation and perturbation of the plant parameters, but also possesses the adaptation to control quality of variable structure control systems. the simulation results show the chattering in vsc systems is highly reduced

    文摘:分析了變結構控制設計方法中趨近律參數的物理意義及參數之間的定性關系，根據這些參數的定性和不精確關系，提出了基於模糊規則的趨近律控制? ?模糊趨近律控制，即用模糊規則來選擇趨近律的參數，以達到改善品質控制的目的.模擬結果表明，筆者給出的方法既保留了傳統趨近律方法所具有的較強魯棒性優點，又使控制系統的品質控制具有較強的自適應性，同時還比傳統趨近律方法更有效地削弱變結構控制系統中固有的顫振

  7. The algorithm transforms 2 - dimesion image data to 1 - dimension data by projecting the character binary image on vertical and horizon direction, as to a character image of w x h size, it reduced the operation time from about w + h level to about w x h level compared to the traditional algorithm and greatly reduced the time complexity of later processing, meanwhile it saved enough vertical and horizon lattice distribution information of the character

    演算法通過將字元二值化點陣圖像進行垂直與水平方向投影，實現了從二維圖像數據到一維數據的轉化，對于w h大小字元圖像，相對于傳統演算法，本演算法將運算量從w h數量級將至w + h數量級，大大降低了后續處理運算的時間復雜度，同時保留了足夠的關于字元垂直及水平點陣分佈的特徵信息。
  8. This paper introduces some practicable ways to realize the design of background signal simulator console software, database exploitation and the data processing for the gps receiver ( gn - 79 ). to meet the needs of these superiorities such as simple maneuverability, modularization and high secrete security, we considerably think of those requirements in the aspects of the signal - producing, hardware - setting, timing and orientation, user setting and so on, during the period when we design the software, make the database accessing down to the bottom layer, and obligate full space for its improvements of software modification and function expansion
