单词	chromosphere
释义	chromosphere /ˈkrəʊməsfɪə / noun Astronomy A reddish gaseous layer immediately above the photosphere of the sun or another star which, together with the corona, constitutes its outer atmosphere.Prominences, flares, plages, and other features of the solar chromosphere can be observed in hydrogen light.... Solar flares appear as sudden, intense flashes in the chromosphere of the Sun. For decades astronomers labored to get good photographs of the chromosphere, and in particular its spectrum. Derivatives chromospheric /krəʊməˈsfɛrɪk/ adjective ... As the Sun went dark the corona became visible to all, although not much of a chromospheric display was seen, with only one notable prominence, perhaps two close by each other. Thus, detection of this resonance will provide an important new constraint on chromospheric models. This expansion of chromospheric plasma up into the corona during a flare is generally called chromospheric evaporation. Origin Mid 19th century: from chromo-2 'colour' + sphere.
