angular momentum tensor 中文意思是什麼
angular momentum tensor
解釋
角動量張量-
Based on the conservation principle of linear and angular momentum, the method derives the equations of the mass and mass center as well as inertia tensor of the new end - effector for the manipulator handling the unknown object
該方法基於線動量和角動量守恆定律,推出了機械臂負載未知目標的新的末端效應器的質量、質心和轉動慣量的方程組。 -
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。
