摘　　要：本文讨论了碱原子钾和钠的受激态能级的布置,得到了NaI和KI的能级按照量子数k值的增加而递增。在给定的“k带”中存在着一个特征模(l_i),能级的顺序由(l_i)确定,而且对于给定的原子的(l_i)与量子数k=值无关。由此构成原子受激能级的k序结构。同时讨论了k带的量子亏损,并引入约化量子亏损σ_(ne),可以证明,当l≤l′时,σ_(nl)的相应序列与原子的特征模(l_i)完全相同。当l>l′时形成H序布置。在l=l′时由k序转变为H序。In this paper, the quantum number k is considered as an energy ordering quantum number for the excited state of sodium and potassium atoms. It is shown that the energy levels of the vanlence electron are energy ordering according to the values of K. Within each K band, there is a fixed sequence of 1 values, for each atom. It has been called the '{l_i}pattern'. Except in a few cases, the levels increase in energy according to the {l_i}, the {l_i} does not change with increasing K.The existence of this phenomenon is called 'K ordering' of the spectum. We have also discussed the K ordering and its relation to the quantum defects. The reduced quantum defects σ_(nl) have been introduced. It is shown that the ordering of the σ_(nl) values for l≤l' determines the nature of the (l_i} of the spectrum. For l≤l', K ordering prevails. For l>l', hydrogenic H ordering prevails. For l= l', it has shown this transition from K ordering to H ordering.
