查询词典 finite continued fraction

In this thesis, a semi-classical model of the force on an atom is used to describe the motion of a two-level atom interacting with a standing wave laser field. The velocity dependent force and momentum diffusion are derived through optical Bloch equations by using the matrix form of the continued fraction technique. By investigating the dynamic properties of atoms in laser field, we can control and manipulate the mechanical motion of an atom.

本文利用半经典理论，从二能级原子在激光驻波场中所满足的运动方程出发，推导出密度矩阵元所满足的递推关系，利用矩阵连分数方法求解出密度矩阵元，从而求出依赖于原子运动速度的光压力与动量扩散系数，通过讨论原子在激光场中的动力学行为，为原子在激光场中被囚禁、形成原子列阵以及可控制的量子态，从而为量子信息处理提供理论基础。

EUR/USD continued to be bounded in established range above 1.2706 last week as consolidation continued. While some more sideway trading might be seen, upside is expected to be limited by 1.3093. On the other hand, below 1.2706 will suggest that whole decline from 1.4719 is resuming for a retest of 1.2329 low next. However, note that a break above 1.3329 resistance will indicate that fall from 1.4719 has completed and bring strong rebound.

EUR/USD 继续着上周建立的1.2706底部之上的反弹，会有更多的震荡交易，上涨的限度预期在1.3093，与此相反，低于1.2706将预示着从1.4719点开始的整个下降趋势将重新再试1.2329的新低，然而，请注意，一但突破1.3329，预计从1.4719开始的下降已经完成，并将带来强劲的反弹
