摘要：
The physical state of ionized gas in NGC 7793 was studied by spectroscopical means: the electronic temperature is Te∼104K while the electronic density ranges from Ne∼1400 cm-3 in the nucleus to Ne∼1000 cm-3 in the emission regions. There are also indications of an excess of nitrogen in the nucleus. The M/L ratio suggests for NGC 7793, a high proportion of young objects quite uniformly distributed over its body, with a slight concentration towards the nuclear region. © 1979 D.
