Second, by computing the trajectory of the missile and the method of analyzing cep, influences that the fighter ' s height, speed, pitch angle, the deflection angle between fighter and target, and the target moving characters make on the times of fighter attack and missile launch are deeply developed. third, by relating the motion of the missile and the fighter, the influences that fighter ' s dive angle and the deflection angle between fighter and target make on the attack field of the fighter are discussed in this paper when the fighter perform vertical and horizontal attack. criterion of attack effect is proposed focusing on attack time of the fighter, trajectory of the missile and destruction probability to the target
本文主要完成了以下幾個方面的工作：對導彈可發射區和飛機可攻擊區進行建模，通過對導彈彈道的模擬計算，並運用典型的圓概率偏差精度分析方法，詳細討論了飛機實施攻擊時，飛機的飛行高度h 、速度v 、俯仰角、與目標的偏離角_ x及目標運動特性等對飛機攻擊時機和導彈發射時機的影響；因此，將飛機和導彈結合起來，詳細研究了飛機在垂直平面和水平平面內實施攻擊時，飛機俯沖角和與目標的偏離角_ x對飛機的攻擊范圍的影響；以飛機實施攻擊的時間t 、彈道特性和對目標的殺傷概率p來評判對地攻擊的效果；最後給出典型算例，通過對空地攻擊過程的模擬實現，對飛機飛行過載提出要求。As these volcanoes grow, they rise above the ocean surface to form lines of islands along the leading edge of the overriding plate
隨著這些火山的生長，它們上升到海面以上會沿著仰沖板塊的前緣形成島鏈。The goal of the dissertation is based on a doctrine which to find a road to break long - disturbing the chinese nation structual cultive of " self - ambition and self - contempt " double psychological conflict. with the central issue of rational resetup national self - confidence, and on the guide of historical materialism and dialectic materialism, then carry on several tentative research as following : firstly, as viewed from culture, the author reexplain the connotation and extention of national self - confidence, reveal the functional relationship between national self - confidence and culture. bring up a new opinion that national self - confidence stem form national culture, and it is a belief in national culture, it becomes rational base and inner power of national consciousness
