A simulative algorithm of laser beam scattering by an object in near field is given. based on the algorithm, a simulative software is worked. and by using geometrical modeling and hiding, the received power of remote system for f16 airplane, as an example, is computed
4 、提出激光引信目標近場散射特性模擬演算法，編制了模擬軟體，並以f16飛機為例，通過幾何建模和消隱處理，計算了目標不同姿態、不同脫靶量和不同脫靶方位角時，彈目交會過程激光引信接收系統的接收功率。The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take - off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. the neutron flux at different wavelength, under different reflection and take - off angle of the monochromator and divergency of the first collimator, were given. the simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected
用蒙特卡羅模擬方法對中子應力衍射譜儀的設計方案進行了優化研究，提出了一系列可供參考的數據：確定了單色器的位置、尺寸、垂直聚焦單色器在不同起飛角下的聚焦曲率半徑和傾角；討論了第二準直器的尺寸和發散，以及使用第二準直器造成的強度損失；給出了在不同單色器反射面、起飛角、中子波長和第一準直器發散度的情況下樣品處的中子注量率，以及多種組合情況下譜儀的解析度曲線；對限束方孔的尺寸、距離樣品遠近對強度損失和測量中的影響做了深入研究。However, when extremely high oblique impacts occurred ( 55 degrees or more ), as on turret roofs and decks, face - hardened armor, due to its brittleness, was a very poor choice since it could break and throw pieces into the region behind it even if the shell glanced off
然而當炮彈以極大的彈著傾斜角（ 55度或以上）擊中炮塔頂部和甲板時，由於裝甲的脆性，即便炮彈只是擦過，裝甲的背面也會破碎飛散，這時表面硬化裝甲便是個拙劣的選擇了。The experimental results show that the wave shaper can control the moving direction of the rod fragments after the warheads exploded and ensure the integrity rate of the rod and that there is a close relationship between the flight attitude and the positioned angle, which is mainly reflected by the rotation velocity of the rod
試驗結果表明：採用波形控制器可以較好地控制戰斗部爆炸后桿形破片的飛散方向，以及保證桿條的完整率；桿條的飛行姿態與放置角有密切關系，主要通過桿條旋轉速度表現出來。The backward scattering field of extended target is approximated as the synthesis of many strong scatter centers on target, and geometric optical method is used in establishing deterministic model of a aircraft in the paper, the model is used to evaluate the performance of frequency diversity in suppressing glint at last
本文將復雜目標後向散射回波近似為目標上若干強散射中心回波的合成，結合幾何光學法得到了某種飛機目標的確定性模型，並用該模型評定頻率分集對角閃爍抑制的改善性能。This was much less likely with soft homogeneous armor that could dent and tear slowly, easing the shell away and staying more intact, with few pieces torn off
然而當炮彈以極大的彈著傾斜角（ 55度或以上）擊中炮塔頂部和甲板時，由於裝甲的脆性，即便炮彈只是擦過，裝甲的背面也會破碎飛散，這時表面硬化裝甲便是個拙劣的選擇了。The continuous signal is transformed to the discrete signal which it could be recognized the computer through input signal circuit and aid transformation circuit. the discrete control signal which it is output by the computer is transformed to the continuous control signal through output signal circuit and d / a transformation
將檢測到的連續角信號經輸入信號電路和a d電路轉換為飛控計算機識別的離散信號；將飛控計算機輸出的離散控制信號經輸出信號電路和d a電路轉換為滑翔彈的連續控制信號。The proposition of the data warehouse is taking development at full speed of relation data base, undertaking the parallel processing of and distributed technology as foundation, solve possession a large amount of data but useful information poor ( data rich - information poor ) comprehensive solution that information technology exist in development online analysis processing and go on technology that analyses to multidimensional data, from analyses it way obtain analysis datum of aid decision that user need from various visual angles
數據倉庫的提出是以關系數據庫、并行處理和分散式技術的飛速發展為基礎的，是解決信息技術在發展中存在的擁有大量數據但有用信息貧乏（ datarich - informationpoor ）的綜合解決方案。聯機分析處理是對多維數據進行分析的技術，它從多視角分析途徑獲取用戶所需的輔助決策的分析數據。分享友人
