Expansive components in HII regions

We study the presence of low intensity high velocity components, which we have termed wing features in the integrated Halpha emission line profiles of the HII region populations...本研究针对电离氢区（H II region）族群的积分Hα（Halpha）发射线轮廓，探究其中被我们命名为翼状特征（wing features）的低强度高速成分的存在情况……
