  1. The complex nonlinear pursuit - evasion model of two spacecraft in near - earth coplanar orbit is simplified to linear model, the circular region the radius of which is equal to capture radius is defined as target set, capture is achieved when the evader come into the target set and the game is over ; the boundary of useable part ( bup ) is determined, and the analytical form solution of the linear equations is obtained by backward integration of the state variables from the bup, the linear barrier of the pursuit - evasion model and the optimum thrust of the both sides are thus obtained

    本文將近地共面軌道內運動的兩飛行器非線性追逃模型簡化為線性模型，以捕獲半徑的圓域定為目標集，確定目標集邊界上的可用部分，並以此為各狀態變量的起點，對時間進行倒向積分，求得線性方程組的解析解，從而確定了該追逃模型的線性界柵，以及界柵上對策雙方的最優推力，即求得了滿足最優策略時相對運動的軌跡和推力。
  2. Based on the kinematical design criterion of equi - chord percent ratio and spatial rigid body guiding mechanism, three theoretical design methods of arc track, non - arc track, and helical track are proposed in this thesis, meanwhile, different design methods about prime flap and sub - flap driving mechanisms are completed. three cases of different three - gaps - fowler - flap tracks are designed

    對后緣三縫富勒襟翼工作時的3個關鍵位置，按照「等弦長百分比」運動的設計準則和空間剛體引導機構的設計思路，提出了圓弧軌道、非圓弧軌道和螺旋線軌道等3種空間位置引導軌道的設計原理，並分別給出主襟翼和子襟翼驅動機構的不同設計方法。
  3. We consider a nonlinear differential equation periodic boundary value problems of second order which has proposed as a model for the periodic motion of a satellite in its elliptic orbit

    摘要本文考慮作為衛星繞橢圓軌道做周期運動模型的一個非線性微分方程的周期邊值問題。
  4. In terms of efficiency in energy consumption, traveling among planets in straight lines not from desirable. today, space probes customarily make use of hohmann transfer orbits and gravity assists in their interplanetary endeavours. this method, though still quite costly, does help to save fuel to a certain extent

    在太陽系的行星中穿梭，直線航行並非理想的路線，現在的探測船均使用赫曼轉移軌道以太陽為焦點連接行星的橢圓軌道，再配合行星推助的技術航行探測船經過行星時偷取行星的能量加速或減速。
  5. The comparison of the computational results of flap movements indicates that three operational positions of the wing flaps guided through the different tracks are nearly close to each other and the non - arc - track is better to guide the flaps to the original three positions exactly

    計算結果表明，不同的軌道下所得的襟翼3個工作位置從幾何角度看比較接近，其中非圓弧軌道能夠使襟翼在3個工作位置與預先設計的姿態完全相同。
