光纖拉曼放大器因其特有的在線、寬帶、低噪聲等特點而越來越被人們關注，是一種非常適合下一代超大容量、超長距離dwdm系統的光放大器，尤其是在海底跨樣光纖通信、超長距離光纖通信以及開發整個光纖低損耗窗口等方面有著不可替代的優勢。An on - line minimum - variance estimator was developed for thrust acceleration applied to orbit transfer using discrete - time radar measurements. the mass - flow - rate of propellant was selected as a state variant, which was estimated by employing an integral state model and ekf filter. the variation equations for measurement vector to mass - flow - rate have been established to linearize the discrete - time measurement equations. the algorithm has applied successfully to maneuver process in commanding satellite into geo - stationary orbit. the results show that the algorithm developed here can monitor and determine whether engine works well or failure precisely and quickly during orbit transfer process
飛行器軌道機動過程中，為跟蹤、定位機動目標和干預機動控制過程，需要統計處理離散的雷達觀測量實時估計推進發動機的推力，進而確定飛行器的瞬時軌道參數.本文所述演算法是該工程問題的探討和解決方案.文章建立了軌道機動過程中連續變質量運動模型和離散雷達量測模型，推進發動機的質量秒耗量作為表徵推力加速度的一個近似常量，應用擴展卡爾曼濾波對離散的雷達測量數據進行順序統計處理給出秒耗量的最小方差估計;文章詳細地推導了線性化量測模型的變分方程和觀測矩陣;模擬結果表明該演算法能快速、準確地估計推進發動機的質量秒耗量和向機動目標施加的實際推力When oman ' s oil runs out and natural - gas flares no longer cast an eerie midnight glow on the dunes near the lekhwair oil fields, the government hopes that farming, fishing, and mining industries will be strong enough to sustain oman ' s economic progress
當阿曼的油氣資源耗盡的時候，列克威油田上再也不會有天然氣燃燒的詭異火焰照耀沙丘的夜晚，政府希望耕種、漁業和礦業的發展能夠在將來維持阿曼的經濟。To accelerate the development of next generation high dwdm system, the pape r also researches the property of gain. based on optical wave nonlinear transmission equation, the gain model of fra is established. by the way of numerical analysis, it is obtained that the gain of fra has relation with pump power, input signal wave power, the effective area and absorption of fiber. the obtained conclusion has definite instruction to the design of fra
為了促進下一代超高速dwdm密集波分復用技術的發展，本文還研究了光纖喇曼放大器的增益特性，根據光波非線性傳輸方程建立光纖喇曼放大器增益模型，通過數值模擬分析了泵浦波功率、信號輸入光功率、以及光纖有效面積和損耗對光纖喇曼放大器增益的影響，得出了一些對光纖喇曼放大器的設計有一定的指導意義的結論。The problems facing mr obermann include the loss of 1. 5m fixed - line german customers in the first nine months of the year ; growing competition from cable and mobile operators ; a workforce which is at least 30, 000 too big coupled with an agreement not to cut jobs except by natural attrition until the end of 2008 ; and a legacy of 77, 000 employees with civil - servant status, which means they cannot be fired
奧伯曼所面對的問題包括：今年前九個月，有150萬德國固定電話用戶流失；與有線設備和移動運營商的競爭日漸激烈；至少3萬人之眾的員工隊伍規模龐大，而且（公司與之）協定在2008年終之前除非人員自然損耗，否則不得裁員；以及具有公務員地位的7萬7千名雇員，這意味者他們不能受到裁撤。American sherman. 50cal turret mount cost reduced from 100munitions to 75munitions
美軍點50炮塔機槍（謝爾曼坦克的升級）彈藥消耗由100降低到75 。A semi - discrete form of our scheme is also presented. this new reconstruction is a third order accuracy in smooth regions and non - oscillations at cell interfaces. our scheme enjoys the main advantage of the central schemes - simplicity, namely it does not employ riemann solvers and hence the intricate and time - consuming characteristic decomposition are avoided
本文針對一維雙曲型守恆律的初值問題，研究了二階和三階中心差分格式，提出了一種改進的三階中心差分格式及其半離散形式，主要是引入了一種新的重構，並證明了這種重構在光滑區域具有三階精度且在網格邊界無振蕩，所提的格式保持了中心差分格式簡單的優點，不需要求解黎曼問題，避免了復雜且耗時的特徵分解過程。分享友人
