由于热等离子体发射的软X射线谱的分辨率较低，未分辨跃迁阵模型是一个方便的解释工具。本文导出了任意中等耦合阵线波数加权分布的一阶和二阶矩的简洁公式，给出了平均波数和阵宽。作为补充，给出了阵列的许多性质，例如，优先退激、能级和谱线统计以及组态混合效应。
Because of the low resolution of the soft-X-ray spectra emitted by hot plasmas, the model of Unresolved Transition Arrays is a convenient tool for their interpretation. Compact formulae have been obtained for the first and second order moments of the weighted distribution of the line wavenumbers of any array in intermediate coupling, giving the average wavenumber and the width of the array. In supplement, many properties of the arrays are presented, e.g., the preferential deexcitation, the statistics of levels and lines, and the effect of configuration mixing.
