摘要：

We present observations of the classical nova V1974 Cygni (Nova Cyg 1992) obtained with the ISO Short and Long Wavelength Spectrometers (SWS and LWS) and the spectrometer section of ISOPHOT. We identify [Ne III] lambda 15.5, [Ne V] lambda 14.3, 24.3, [Ne VI] lambda 7.6, [O III] lambda 51.8, [O IV] lambda 25.9. There is evidence that the Ne and O emission arises in physically distinct regions of the ejecta. We determine the electron temperatures in the Ne- and O-bearing regions of the ejecta, and estimate the Ne abundance relative to O.
