asymptotic condition meaning in English

渐近条件

At the other hand , we can perform the rrpa calculation with the continuum replaced by a set of outgoing single particle resonances , it indicates that the resonances in the continuum play an important role in the description of nuclear dynamical processes , such as collective giant resonances . energies , widths and wave functions of the single particle resonant continuum are determined by solving scattering states of the dirac equation with proper asymptotic conditions for the continuous spectrum in the r ' elativistic mean field theory . the relativistic regular and irregular coulomb wave functions are calculated numerically
在进行相对论无规位相近似计算时将连续谱中所有的正能态用单粒子共振态来代替，并且在计算中采用单粒子共振态的真实宽度，利用这种方法我们计算了核的同位旋标量巨八极共振响应函数，并且和考虑了连续谱中所有正能态贡献的结果进行比较，计算结果表明，连续谱中只考虑单粒子共振态对核的集体激发的贡献时，给出的响应函数基本上能够重现考虑了所有正能态贡献时的计算结果，这说明了在核的集体激发中，连续谱中主要是单粒子共振态的贡献。
