over spin造句
- 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。 - 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
總之，本文為雙電子原子能級的相對論修正和精細結構的理論計算提供了一種新的方法，包括原子哈密頓算符的球張量表示方法、原子哈密頓中各種相互作用項的角向矩陣元和自旋求和的計算方法，以及徑向矩陣元的近似計算方法 - It's difficult to see over spin in a sentence. 用over spin造句挺難的
