orbit approach 中文意思是什麼
orbit approach
解釋
接近軌道-
The most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. )
近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深人到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞。 -
The asteroids are the most important small bodies in the solarsystem, and they mainly lies in the two locations - a main belt between the mars ' s orbit and the jupiter ' s and the near - earth space. the most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. ). the characteristic brings about some difficulties in the numerical research during their orbital evolution, which leads to the failure of the normalization technique in the general removal impact singularities of celestial mechanics methods and the symplectic algorithm which is successfully applied to the investigation in quality. by comparing the computation effects of several common numerical methods ( including symplectic algorithm ), and considering the nature of the movement of the small bodies, the corresponding treatments are provided here to improve the reliability of the computation
小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深入到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難，包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法（包括辛演算法）計算效果的比較，根據小天體運動自身的特性，給出了相應處理措施，從而可提高計算結果的可靠性 -
Based on the theory of software architecture, the hierarchical structure is used for designing the software system because the aocs demands real - time and high reliability. the integrated environment for software cross - development of vxworks is used for simulating the schedule of several multi - tasks, the managing of work mode and the communication among the modules. an approach of software architecture for the attitude and orbit control system of satellite is developed in this paper, which is based on a deep study and analysis of modern software techniques

In the right orbit, an external ethmoidectomy was done, while in the left, a transnasal endoscopic approach was used to remove the inferomedial wall
兩邊皆以外側眼眶切開術行外側眼窩減壓術合併內側及部分眼窩底減壓術。 -
When one circle of angle observing data is available, a new kind of method, diagram approach, is presented when only short - arc angle measurements is available, the genetic algorithm ( ga ) is used for orbit determination
當具有半四以上觀測弧段時，提出了一種圖解法確定衛星軌道；當觀測弧段較短時，採用遺傳演算法確定衛星軌遭。 -
( 2 ) a new perturbation method for noise reduction of chaotic signal is promoted, the approach consists of deploying a series of proper disturbance to the observing orbit yn = ( yi, y2, . -. j / / ) ? so as to gradually acquire the estimation xn - ( jc, 5c2, . ., jcw ) of the real orbit xn = ( * i, x2, . ., xar )
