球张量 meaning in English
spheric tensor
Examples
- Spherical tensor of strain
应变球张量 - Spherical tensor of stress
应力球张量 - 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
具体内容包括：首先，借助角动量耦合理论，将多电子原子哈密顿算符中的自旋-自旋、自旋-其它轨道以及轨道-轨道相互作用全部改用球张量表示，这种球张量形式的优点在于已将原子哈密顿算符中的径向、角向和自旋部分完全分开，从而便于计算矩阵元，而且角向矩阵元可以方便地利用不可约张量理论来进行计算。 - In a word , a new method that theoretically calculates the relativistic corrections and the fine structure of the energy levels in two - electron atom , including the atomic hamiltonian expressed by spherical tensors , the calculation of the angular matrix elements and the summations over spin of the various interactions in the atomic hamiltonian , and the approximate calculation of the radial matrix elements , has been provided in this thesis
总之，本文为双电子原子能级的相对论修正和精细结构的理论计算提供了一种新的方法，包括原子哈密顿算符的球张量表示方法、原子哈密顿中各种相互作用项的角向矩阵元和自旋求和的计算方法，以及径向矩阵元的近似计算方法
