摘要：

行星状星云（PNe）和H { \sc ii}区的光谱研究推动了原子物理学的发展。在过去的几年里，一代强大的天文台，更复杂的光谱建模代码的发展，以及大量生产高质量原子数据的巨大努力的结合，导致我们在理解这些天体的原子光谱方面取得了重要进展。在本文中，我回顾这些进展，包括评价原子数据与星云光谱，检测谱线，从大多数铁峰元素和n-捕获元素，观测超精细发射线和同位素丰度分析，荧光过程，和新技术诊断的基础上复合光谱的物理条件。该评论是针对原子物理学家和光谱学家试图建立原子数据和模型的当前状态，并了解主要的常设问题。

英文摘要：

Spectroscopic studies of Planetary Nebulae (PNe) and H {\sc ii} regions have driven much development in atomic physics. In the last few years the combination of a generation of powerful observatories, the development of ever more sophisticated spectral modeling codes, and large efforts on mass production of high quality atomic data have led to important progress in our understanding of the atomic spectra of such astronomical objects. In this paper I review such progress, including evaluations of atomic data by comparisons with nebular spectra, detection of spectral lines from most iron-peak elements and n-capture elements, observations of hyperfine emission lines and analysis of isotopic abundances, fluorescent processes, and new techniques for diagnosing physical conditions based on recombination spectra. The review is directed toward atomic physicists and spectroscopists trying to establish the current status of the atomic data and models and to know the main standing issues.
