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。For years, sheng meei machine mfg., co. has under chairman mr. pin lee competent leadership, excellent performance of everyone in sheng meei and reliable quality of these machines, sheng meei mfg., co. has now become one of the largest knitting machinery manufacturers in the world. the distinct machine quality and sophisticated function, advanced performance at highest reliability has won industrial confidence and popularity, and had also made sheng meei machine mfg., co, s name being announced fooicially as one of the top 500 enterprises in taiwan. zhang jia gang sheng meei machine co., ltd. is located in china main sweaters shopping center situated in a golden triangle of south jiang su province in miao qiao town. the factory is just twenty kilometers away from zhang jia gang harbor and shang hai porby east, and adjacent to nan tong harbor by north, a perfect location with convenient access to all inland transportation
三十多年來，總公司秉執著永續經營的理念和宗旨，在不進步就是落伍的原則下，不斷地創新與超越，從早期製造銷售各式手搖編織機，至一連串自行開發出全新全自動多功能的電腦自動編織機及提花機，躍居為世界一流水準的電腦毛及編織機製造廠。多年來，在董事長李賓先生的領導下，全體同仁群策群力，本著誠信踏實創新突破之精神，努力經營，不但產品行銷國內各地，而且遍及亞洲美國中東中南美洲與非洲等國家和地區，深受客戶的肯定信賴與喜愛。今日的盛美公司，更是世界數一數二的手搖及全自動毛衣編織機製造廠，躍居世界領先地位。Aimmed to retard the response of ballistic missile defence system, the wavy trajectory with three crests is designed in this thesis to replace traditional parabola one. this kind of trajectory make anti - defence system have lots of difficulties to detect and compute the track and destination of ballistic missiles before reentry. so, applying the wavy trajectory can greatly improve the anti - defence ability of ballistic missiles
從延緩導彈防禦系統的早期預警時間著手，將傳統彈道導彈的拋物線彈道中段設計成有多個波峰的跳躍式彈道，使得探測系統在導彈再入大氣層之前，很難準確探測和計算導彈的落點，使得防禦系統防不勝防，從而大大地提高了彈道導彈的突防能力。The world economy strids forward to be knowledge, to be information and to be service step by step under the promotion of sci - tech revolution since 1970 ", and structural contradiction is prominent in china ' s economic development ; the implementation of non - equilibrium development strategy of regional economy has promoted the east coastal areas made a leap economic development, while the economic development of west areas is relatively slow, and the gap between east and west is expanding continuosly
20世紀70年代以來，在新科技革命的推動下，世界經濟逐步向信息化、網路化和服務化邁進，我國經濟發展的結構性矛盾突出，在世界產業分工體系中處于不利地位，產業結構面臨優化升級的嚴峻考驗；區域經濟非均衡發展戰略的實施，推動東部沿海地區經濟跳躍式發展，而中西部地區經濟發展相對緩慢，東西部差距不斷擴大。分享友人
