Kinematic distance ambiguity in HII regions

Using H I absorption spectra from the International Galactic Plane Survey, a new method is implemented to resolve the kinematic distance ambiguity for 75 H II regions with known...基于国际银道面巡天（International Galactic Plane Survey）的氢Ⅰ（H I）吸收光谱，本研究提出并采用一种新方法，用以解决75个已知[原文未完整收尾]氢Ⅱ（H II）区的运动学距离歧义。
