摘要: We present observational evidence, from Hαin face-on galaxies, which strongly favours the hypothesis that escaping photons H II regions are basic cause of ionization diffuse ionized gas in galaxy discs, and by implication chief Reynolds layer Milky Way, refer reader to models based on these observations go further, geometrically, confirm this conclusion.
