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。 -
A new model for the growth stage of surface flashover has been developed according to the experimental results, which is based on the solid band theory. it is suggested that the electron multiplication could be attributed to two processes : one is the secondary electron emission avalanche caused by collisional ionization, the other is the micro - discharge caused by the trap centers of insulator. the trap cente
電子倍增的過程與材料的表面態直接相關，材料微觀結構的變化和材料的表面處理都能夠導致材料表面態的變化，引起材料的表面二次電子發射系數以及材料中陷階密度和分佈的改變，從而影響了電子倍增的過程，並進一步改變或影響了沿面閃絡的發展過程。 -
The article structure the landslide prevention and cure, the structure of prestress anchors and its application in detail. basing on the geology condition of fabricating yard, we calculate the solid power and the length of anchor rope. we have worked out the experiment research scheme, and has carried on the earlier stage experiment, field demarcation experiment and has opened pulling the experiment on the spot. ten teams of steel rope to two teams of structure types twist the experimental data that thread internal stress and the total pulling force has been in progress research, and has put forward raising the measure of solid capability of prestress anchor and administering possessing
