论文摘要
对类星体发射线特性的研究和光谱参数之间的关系对于理解起源于活性银河核不同区域内的物理机制很重要。在本文中，我们调查了从斯隆数字天空调查数据发行7的1型类星体的光谱参数7类星体目录（ARXIV：1006.5178 [astro-ph.co]）。频谱参数是等效宽度和最大狭窄线和宽线一半的全宽度。我们对样本的相关矩阵和主成分分析进行分析。我们得到狭窄的鲍德温效应足够重要，值得进一步研究。我们在几个狭窄的线上提供了鲍德温效应的相关系数和斜率值。
Investigation of quasar emission line properties and relationships between spectral parameters is important for understanding the physical mechanisms that originate inside different regions of the active galactic nuclei. In this paper, we investigate the optical spectral parameters of type 1 quasars taken from the Sloan Digital Sky Survey Data Release 7 Quasar Catalog (arXiv:1006.5178 [astro-ph.CO]). Spectral parameters, such are equivalent widths and full widths at half maximum of both narrow and broad lines are taken into account. We perform the analysis of correlation matrix and principal component analysis of our sample. We obtain that the narrow line Baldwin effect is significant enough and deserves further investigation. We provide the correlation coefficients and slope values for Baldwin effect in several narrow lines.
