The basis of dynamics and simulation includes the iterative flyout angle algorithm to the solutions to lambert problem and battin ' s universal conic section state extrapolate method. then spacecraft ' s orbit roots, maneuver impulse and maneuver time are discussed as the following four part : first of all, the chaser ' s one orbit roots is selected as a variable to simulate its influence to the large scale orbital maneuver. the research reveals fact that the orbit roots both of chaser and target should be close to each other to achieve better maneuver and rendezvous " ability, moreover, the best orbit maneuver and rendezvous occurs when both chaser and target ' s initial phase angle are equal
為了研究了交會機動中追蹤器和目標器的軌道根數、機動時限和機動能耗等因素對交會機動的影響，模擬和分析分為以下四個部分:首先，研究了追蹤器軌道單個參數為變量情況下兩航天器大范圍交會機動問題，研究表明，追蹤器的變化參量與目標器相應的參量在接近的情況下可以獲得良好的交會機動特性，而對于兩航天器軌道共面的情況下，初始相位角相等時則獲得最佳的機動效果。 -
( 4 ) as an application of wavelets, the first, wavelet - based solution to ode to be researched, the second, construction the hermite b - spline bases scale functions with boundary conditions on the interval, combining with garlerkin method, to solve differential equation in finite - length beam problem ; the third, m - scaling function solution to ode in dynamics
（ 4 ）把小波函數用於微分方程的求解中。首先利用插值小波求解常微分方程，其次，滿足邊界條件的小波尺度函數，結合galerkin方法求解結構力學中的微分方程；最後，使用m -尺度函數求解梁結構中的微分方程。 -

Grid generation is a pivotal technology of cfd ( computational fluid dynamics ). follow the complication of problem in cfd field, the grid generation technology has developed in two ways : in the first place, it improved grid generation method to adopt the increasingly complicated figuration ; on the other hand, it developed new methods to deal with the problem including fluctuant surface, such as multi - body separation problem etc. among this ways, the overlap grid technology is a vive research aspect
網格技術是cfd （ computationalfluiddynamics ）領域中的關鍵技術。隨著cfd涉及問題的復雜化，網格技術在兩個方向上逐步發展:一方面針對不斷復雜的外形處理需求改進網格方法，從而能夠模擬復雜飛行器及其各個氣動部件的細節;另一方面發展適應撲翼、多體分離等變幾何外形問題的網格方法，使得cfd的工程應用領域不斷拓寬。這其中，重疊網格方法是一個較有活力的研究方向。
