摘要：

This paper presents LTE analyses of two sharp-lined early B stars, gamma Pegasi and l Herculis, based on co-added IIaO and Reticon 2.4 A mm-1 spectrograms of the photographic region. Most of the derived abundances are close to solar. Both stars have definite microturbulences which probably are related to the instability of their photospheres.
