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。

Especially the concerning headache of losing truth on financial information, as well as the popularity of the internet, the appearance of internet financial reports, how to normalize the future financial reports has been put in front of the world
特別是財務報告的信息失真，再加上隨著網際網路的普及，網路財務報告的出現，有關未來財務報告的規范問題再次被提起（王惠君2000 ，陳箭深2001 ，張輝中2001 ，王詠梅2001 ，王躍堂張祖國2001 ） 。
