本文提出了一种新的确定复杂自电离原子和离子能级谱线形状和强度的模型。它是基于一个广义线轮廓函数（GLPF）的总轮廓的介绍。GLPF消除了群体动力学和谱线特征计算的分离。推导出统一低密度和高密度限制的分析解，该解允许将种群动力学缩小几个数量级，而不会在使用GLPF时损失光谱细节。精确的数值计算表明，即使在极端条件下，如热电子和瞬态等离子体演化的广义线轮廓函数的方法仍然成立。
A new type of model for the determination of spectral line shapes and intensities originating from complex autoionizing atomic and ionic levels is proposed. It is based on the introduction of a generalized line profile function (GLPF) for the total contour. GLPF removes the separation of population kinetics and line profile calculations. An analytical solution unifying low- and high-density limits is derived which permits to shrink population kinetics by several orders of magnitude without loss of spectral details when using GLPF. Exact numerical calculations show that even under extreme conditions such as hot electrons and transient plasma evolution the generalized line profile function approach holds true.
