Soft-X-ray and EUV observations of 16 large X-ray flares obtained with SOLRAD-11 in 1977 and 1978 are reported and compared. X-rays wre measured in the 0.5-3, 1-8, and 8-16 A bands with ionization chambers; EUV was detected in nominal bands of 100-500, 500-800, and 700-1030 A using Be, Sn, or In-shielded LiF photosensitive surfaces. It is shown that the soft-X-ray and EUV emissions of the flares are mainly gradual and of similar duration and magnitude. The data are considered consistent with a two-component model of flare emission: a persistent component (comprising gradual soft X-rays and gradual EUV) and a brief component (comprising impulsive soft and hard X-rays, impulsive EUV, and gradual hard X-rays), with some mechanism linking the two components.
