The first algorithm is low precise but simple and credible, the second is high precise but complex and incredible. 4 ) developed four kinds of methods aimed to improve precision and credibility of navigation system. the first is parallel sandia inertia terrain - aided navigation ( psitan ) ; the second is tercom + sitan, it can restrain two important disadvantages of sitan ; the third is particle filter - based terrain - aided navigation ( pftan ), the particle filter can reduce the error of navigation ; the last is tercom + pftan, where tercom is looked as monitor to ensure the credibility of navigation system
採用并行sitan方法來提高導航精度，並克服奇異值問題；提出了tercom + sitan方法，綜合利用兩者的優點，在保持sitan導航精度的前提下，有效地克服了sitan的兩個缺點；提出了一種基於連續蒙特卡洛濾波（常被稱為particlefilter ）的地形匹配演算法（ pftan ） ，有效地克服了利用sitan時由於地形隨機線性化帶來的誤差，使導航精度有較大的提高；提出了tercom作為監視器的地形輔助導航思想，並將其應用到連續蒙特卡洛方法上，較大地增加了系統的可靠性和精度。Its main contributions include the following several aspects : firstly, the dissertation constructs the mathematic model of short baseline orientation determination using two geostationary satellites and analyses the applicable conditions of carrier phase interferometry. orientation determination precision is analysed in depth through both the conventional linearized method and monte - carlo computer simulation method, and the mathematical simulation results show that the linearized method has the shortcoming of fairly low elevation error analysis precision in high latitude area so as not to be very appropriate there. by analyzing the definite factors influencing orientation precision, the dissertation develops the concept of orientation dilution of precision, which uncovers the internal cause of exotic error behavior of bi - satellite orientation, and has important guiding significance for practical engineering applications
本文系統地研究了基於「北斗一號」衛星載波相位干涉測量原理實現地球靜止雙星定向的相關技術，主要研究成果包括以下幾方面:首先，建立了利用兩顆地球靜止軌道衛星進行短基線定向的數學模型，分析了載波相位干涉測量的適用條件;採用傳統的線性化解析法及蒙特卡洛隨機模擬法兩種途徑對雙星定向的精度進行了詳細分析，數學模擬結果表明在高緯度地區線性化解析法由於俯仰角誤差分析精度略有下降而不太適合;在分析定向精度確定性影響因素的基礎上，提出了雙星定向精度衰減因子odop的概念，揭示了雙星定向誤差特殊表現的內部機理，對實際工程應用具有重要的指導意義。Secondly, basic model of one - stage investment decision is provided and the effects of the parameters, including the capacity step, time step etc on the simulation are understood at the same time, the algorithm ( monte carlo method ) of basic model is given and the basic model is studied in order to find how the three parameters of demand affect the investment decisions
其次，在一系列假設的基礎上，提出了單階段投資決策的基本模型，分析了規模步長、時間步長、樣本數量等參數對模擬結果的影響，給出了該模型的蒙特卡洛模擬演算法，並對該模型進行了系統研究，明確了需求的3個參數（需求漂移率、需求的波動率和初始需求）如何對投資決策結果產生影響。Firstly, according to the observed data in - situ ( or the empirical parameter data ) and the acoustic logging data, the distribution law of the joint in the computing area can be got. then the network system of the joint can be simulated by the statistical distribution theory and the monte carlo ' s method. and then artificial or automatic dissection program can be used to dissect the fem mesh
首先，根據現場實測資料（或相關經驗資料）和鉆孔聲波資料，求出計算區域的節理裂隙的分佈規律，由統計分佈理論結合蒙特卡洛方法可模擬出計算區域的節理裂隙網路系統，利用人工或自動生成剖分程序剖分成有限元網格。In the state of mississippi, governor haley barbour said today that katrina wiped out 90 percent of the buildings near the coast in the cities of gulfport and biloxi
在密西西比州，州長黑利?巴伯星期三說，卡特里娜颶風摧毀了格爾夫波特和比洛克西兩個城市沿海地區90 %的建築。Argentina, for whom carlos tevez was making a lively contribution to his second start of germany 2006, forced their first and only half - chance of the opening 45 when marauding left - back juan pablo sorin burst through on to a tevez nutmeg and was only prevented from teeing up hernan crespo for the opener by a timely interception from per mertesacker
第19分鐘：在本屆世界盃上第二次首發出場的卡洛斯?特維斯表現非常活躍，他為阿根廷隊贏得了在上半場第一次也是唯一一次的機會：上前助攻的左後衛胡安?索林帶球突破，隨后將球交給了特維斯，然而佩爾?佩爾?默特薩克及時的攔截化解了赫爾南?克雷斯波的進攻。分享友人
