S [ ace debris are the general domination of all man - made objects including fragments and elements thereof, in earth orbit or re - entering the atmosphere, that are non - functional
摘要空間碎片是散布在近地軌道和同步軌道上的非功能性人造物體包括其碎片和零件的總稱。 -
By analyzing the inter - satellite measurement net of walker constellation at some time in geometry and numeric, the correction of system error and random error caused by the change of orbit elements using different type of estimation of inter - satellite measurement net was provided quantitatively
並通過對walker星座某一時刻的星間觀測網進行幾何分析和數值分析，定量給出了利用不同類型的星間觀測網對軌道根數變化引起的系統誤差和隨機誤差的修正情況。 -
Selecting the image elements of earth and moon centers as observed quantity, measurement noise model and observed equations of autonomous navigation system are built up. the spacecraft orbit is determined by using the recursive weighted least square based on ud factorization
在奔選取地心和月心像素作為觀測量，建立了符合實際情況的量測噪聲模型和自主導航系統的觀測方程，並利用基於ud分解的遞推加權最小二乘演算法估計了奔月探測器的軌道參數。 -
Firstly, with the help of angular momentum coupling theory, the hamiltonian for multi - electron adorns is rewritten in terms of spherical tensors. the advantage of this form is that the radial, angular and spin parts are separated completely, which makes it easy to calculate the angular matrix elements by means of irreducible tensor. secondly, theoretical expressions of the relativistic corrections including the relativistic mass correction, the darwin correction terms, the electron - electron contact terms and the orbit - orbit interaction which contribute to the non - relativistic energy for two - electron atom are theoretically derived in the lsmlms scheme
具體內容包括：首先，藉助角動量耦合理論，將多電子原子哈密頓算符中的自旋-自旋、自旋-其它軌道以及軌道-軌道相互作用全部改用球張量表示，這種球張量形式的優點在於已將原子哈密頓算符中的徑向、角向和自旋部分完全分開，從而便於計算矩陣元，而且角向矩陣元可以方便地利用不可約張量理論來進行計算。 -
In the course of these derivation, the orbital integrations and the summations over spin are completed and are presented 3j, 6j, 9j symbols and the radial matrix elements. these derivations are strict and no approximate are introduced. the derivations for the orbit - orbit interaction, the spin - spin interaction and spin - other - orbit interaction, which are fairly complicated, have not been given in the previous literatures
這部分推導工作是嚴格的，沒有引進任何近似，其中軌道-軌道相互作用、自旋-自旋相互作用和自旋-其它軌道相互作用能的理論計算式的推導過程比較復雜，在以前的文獻中沒有給出這些相互作用能的具體推導過程。
