本文首先綜述了國內外現代武器系統隱身技術方法;重點對巡航導彈導引頭罩和飛機雷達艙罩等特殊部位的隱身問題進行了研究,研究了金屬網柵用於導彈頭罩和飛機雷達艙罩隱身的相關理論,推導了金屬網柵結構參數對雷達波屏蔽效率和透紅外關系式;用激光直寫工藝,在玻璃表面上製作了一塊面積為70mm 70mm ,線寬為5 m ,線周期為350 m的金屬網柵;在實驗室里用雷達發射和接收裝置測試了網柵對雷達波的屏蔽實驗;認為利用金屬網柵技術對雷達波具有一定的屏蔽作用,而且不影響精確制導的紅外線高效透過。Waterproof thread terminal for the connection of screened high tension ignition cables
加屏蔽的高張力點火導線的連接用的防水螺紋連接端頭Both ends of the shield are a " floating " ground in most cases, and this creates a complex circuit network consisting of the complex impedance to ground of the output circuit at one end, the complex input circuit impedance at the other end, and the resistance, capacitance, and inductance of the cable in between
大多數情況下屏蔽線兩端是「漂移」的接地端,這就形成了復雜的電路,這個電路的一端相對輸出端的接地點有復雜的阻抗,另一端又有復雜的輸入阻抗以及連接線的電阻,電容和電感。The shield is typically metal foil that is terminated to a pin connected to some low impedance point in the circuit
屏蔽物通常為金屬線圈,該線圈被端接至連接到電路中某個低阻抗點的管腳上。Detail specification for 1. 27 mm pitch, ribbon contact, trapezoidal shaped, shielded i o connector

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。分享友人
