By showing the modern technique, such as bioengineering technology, electronic technology, space technology and so on, used and bringing about a series of changes to teh field of agriculture in our country, the article indicates the huge affection of the science and technology on the agriculture polia. having analysed the straits the science adn technology in our used agriculture and about the trends and ways of future development of agriculture policues, author puts forword some wiews following as : modernizting our agriculture, we must select the way of technuqe intensive ; our agriculture product must depend on the increse of producer ' s quality and the modern science and technology ; only by modern science and technology to reform traditional agriculture can we in the end realize agriculture modernization, so we must vigorously develop modern agriculture including the ecological agriculture taken as aim, the physical agriculture and biochemicl agriculture as means
本文通過展示生物工程技術、電子技術、航天技術等高科學技術在我國農業上的應用及其帶來一系列變化，揭示出科學技術在農業政策制定中的重大作用與深刻影響，分析了當前中國農業科學技術應用中面臨的困境及未來農業政策的方向和道路，提出了如下幾個觀點：要實現我國農業現代化，必須走技術集約的道路；我國農業生產必須轉移到依靠勞動者素質的提高和當代科學技術的基礎上來；我國的農業現代化最終只有通過高科技改造傳統農業才能實現，為此，必須大力發展以生態農業為目標、以物理農業和生化農業為手段的現代農業。The computations are shown to agree well with available experimental and numerical data and the physics of 3d large - scale flow separations and vortex shedding are confirmed. the simulation of the flow around a maneuvering wigley hull is a demonstration of capability for calculations of sway forces and yaw moments acting on a hull moving obliquely at a large range of yaw angles. the focus of study is large - scale cross - section separation flows, bilge - vortex development along the hull in the longitudinal direction and their effects on hydrodynamic forces
應用所開發的求解器，以wigley船型為算例計算了大角度斜航船體粘性流場和水動力，分析了漂角的變化對船體所受到的粘性水動力的影響，相當精確地預報了以橫流分離和般渦生成與泄出為特徵的操縱運動船體特有流動形態及橫向水動力和轉脂力矩，經與現有試驗和計算數據比較，檢驗和驗證了該求解器精確模擬繞斜航運動船體的大尺度分離流動和計算非線性水動力的能力。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。
