  1. Then, the chaser ' s two orbit roots are selected as variable and visualizing the simulation by contour plot. this part of research draws the conclusion the same as the first part when the target ' s orbit is circular orbit, while the selected two variable can be wildly changed if the target ' s orbit is elliptical orbit. next, wait time before orbit maneuver is simulated

    其次，利用可視化的等值線圖研究了追蹤器軌道兩個參數為變量的情況下大范圍軌道機動問題，分析表明對圓軌道目標器交會機動時，追蹤器軌道根數不宜與目標器軌道根數相差過大，而對橢圓軌道目標器交會機動時，追蹤器軌道根數可選范圍較大，機動策略和方法富於彈性。
  2. Established the system of coordinates of roll testing, getting the parameters of equation of tooth face by solving the non - linear equations set ; according to the differential geometry and meshing principle, deduce the curvature parameters of tooth face and tooth profile, and get the parameters of instantaneous contact ellipse. emulate the contact trace and contact area of the working tooth face, and drawing the instantaneous drive ratio error curve

    建立了克林貝格擺線齒錐齒輪嚙合分析的對滾模型，通過對非線性方程組的迭代求解，得到齒面方程的各個參數;由微分幾何和切齒嚙合原理推導了齒面上齒廓和齒線方向的曲率參數，得到了瞬時接觸橢圓的參數。根據設計參數和機床調整參數繪制了工作齒面的接觸軌跡和接觸區圖形，並求得了瞬時傳動比的誤差曲線。
  3. First in section 1 we obtain the estimate of holder norm in time direction about the system of elliptic equation and elliptic equations by difference method and the result will be used in chapter 2

    當恆星畫出的橢圓彼此間繞轉速率差異甚大時，星系不會出現波動結構。
  5. In this study, the effect of rotating elliptical inner cylinder on the instability of flow field, the relationship between azimuthal wave speed and the angular speed of inner cylinder, and the so - called ' hysteresis ' will also be investigated experimentally

    本文主要目的除了藉由實驗比較橢圓與圓形截面內柱兩種系統加速過程中不穩定發生時機、流場流況的差異外；對于所謂的遲滯現象于兩系統中的發生過程亦將探討，此外內柱幾何形狀所造成高階不穩定於圓周方向的波形相速度變化，也是本文的探討重點。
