  1. In this thesis, based on pershing ii surface to surface missile, a new kind of ballistic missile was designed with an additional rocket engine, which can be ignited twice. firstly, aerodynamic computational models of missile body and warhead which reentry with supersonic are built according to the task requirements ; secondly, the propulsion system model of missile is built whose first two stages are solid rocket engines and the third stage is liquid - solid combined rocket engine. the nozzle and the shape of the engine are designed to meet the needs of the populsion project ; thirdly, the trajectory model of the mass point is built and a wavy trajectory is designed & optimized ; finally, the ability of a missile ' s breaking through defence is analyzed

    以美國潘興導彈為原型，增加可兩次點火的末級發動機，改裝成具有跳躍能力的地地彈道導彈；首先，根據任務需求，建立了導彈的氣動模型，並建立了彈頭再入時高超聲速氣動模型；其次，建立了導彈推進系統模型，前兩級採用了固體火箭發動機，第三級採用了固?液組合火箭發動機，並在總體方案要求下，對發動機噴管和外形進行了設計；第三部分，建立了導彈質點彈道模型，設計了一條跳躍式彈道，並對跳躍式彈道進行了優化設計；最後，對導彈進行了突防能力分析，從分析的結果可以看出，跳躍式彈道的突防能力比常規的拋物線彈道要強。
  2. A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, lift, thrust, or propulsion

    翼剖面；機翼；翼面一個部件或平面，如機翼、螺旋槳葉、方向舵等，其形狀或方位控制穩定性、方向、抬升、沖擊或驅動
  3. On the action of magneto mechanical coupling of rotating magnetic field generated by turning of exterior driver, robot was spun to generate propulsion in axial direction under the function of fluid dynamic pressure distributed on spiral surface of the robot, as a result, spiral and drive motion of the capsule type micro robot in intestine was realized

    通過外驅動器的旋轉產生旋轉磁場，藉助于磁機耦合作用，驅動機器人旋轉並在其外螺紋表面形成的流體動壓力作用下產生軸向推力，進而實現膠囊式機器人在腸道內旋進。
  4. Body roll occurs largely to position sets of muscles to move joints to produce longitudinal forward propulsion and coupled with the arm pull produces a more direct propulsive force off the hand / forearm - propelling surface

    身體的滾動幅度大會使肌肉群一起運動產生縱向的推進力而且是兩倍于手臂劃水直接產生的推進力。
  5. An elevation of the shoulder, medial rotation of the upper arm, and late flexion at the elbow as the body rotates to accommodate an " elbows - up " position and to reposition the forearm / hand drag surface to where forward propulsion can be created

    提肩，上臂轉一半，然後屈肘使身體轉動達到一個高肘位置接著重新入水並使前臂和手掌通過抱水能夠產生向前的推進力。
