Photoelectric spectra have been obtained for a number of early-type stars in the 1100- to 2000-angstrom region with the Mariner 9 ultraviolet spectrometer. The resonance lines of H I, Si IV, and C IV are easily identified, as are features due to C II, C III, Si III, Fe II, N IV. The absolute energy distribution derived from the data lie about 20 percent below those of OAO-2 in the 1200- to 2000-angstrom region.
已用“水手 9 号”紫外分光计获得了在 1100-2000 埃区域内若干早型星的光电光谱。H I、Si IV 和 C IV 的共振谱线很容易识别，还有 C II、C III、Si III、Fe II 和 N IV 的谱线。从这些数据得出的绝对能量分布，在 1200-2000 埃区域比 OAO-2 的约低 20%。
