本文先後論述了兩種不同的自底向上分析方法來實現開放式考試系統，即slr （ 1 ）分析方法和算符優先分析方法。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。When simple expressions are combined to form a complex expression, the data type of the result is determined by combining the rules for the operators with the rules for data type precedence
當將簡單表達式組合為復雜表達式時，結果的數據類型取決于運算符規則與數據類型優先級規則的組合方式。
