In order to make the theoretical calculation feasible, we first obtain an analytical formalism of partial integrals with respect to the coordinates of the core and target in the phase - shift functions and their cross terms of scattering matrix elements, if the density distributions of the core and target are fitted to a few gaussian forms. then the rest multidimensional integrals with respect to the impact parameter and coordinates of halo nucleons are performed by a monte carlo method
為使理論計算變得可行，我們在核芯和靶核密度採用多個高斯分佈擬合的情況下，解析求解了各個散射矩陣元中的光學相移函數及交叉項含有的與暈核核芯、靶核密度分佈有關的積分;同時對與碰撞參數和暈核子坐標有關的積分（八重以上，並且積分維數隨暈核子數很快增加）採用蒙特卡洛方法計算。During this paper, definition of the measure enter - cover - probability is given, andthree - dimension detection space are transformed to level detection circles on differentheights. aiming at the most normal situation of symmetric line, cross - to line and cross - awayline taken by the carrier, probablely - enter - cover - target - distribution are analysed in relativemovement method on the premise that targets fly perpendicular to the flying direction of thecarrier. mont - cario method is used to simulate uniformly - distributed - targets situation and getthe measure, and results are used to analyse the influence of line - landscape - orientation - ratio, line - portrait - ratio, and speed - ratio on the measure. for further research, influences of height and blind space are also discussed on base ofradar level detection range, and situations of non - uniformly - distributed targets are alsoresearched
為了分析主動探測空間動態性能，本文首先提出以「目標進入雷達覆蓋區概率」 （簡稱為「覆蓋率」 ）作為評價指標;然後將三維探測空間轉換為不同高度層對應的水平探測圓，針對載機採用雙平行航線、交叉相向航線和交叉同向航線的最一般情形，採用相對運動的方法，分析目標垂直入侵時可能進入雷達覆蓋區的目標分佈情況;再運用蒙特卡洛法進行模擬計算，分析並比較目標服從均勻分佈時航線橫比、航線縱比及速度比對性能的影響。The cross short rollers guide way and servo feed - system are the most important parts of 3mz204cnc bearing internal grinding machine made by luoyany bearing research institute. - we have analysised firstly the factor of influence with roller guide way rigid, and we have obtained a load - distortion curve. we also have analysised the dominating factors influence with distinguish ratio of guide way, and we have obtained a solution about pre - tighted load which were tested by experiments
