标题： Determination of T_eff and log g for A0 type stars and its impact on the interpretation of the HR diagram with the HIPPARCOS results

摘要： “基本参数”T_eff和log g对于一组矮星A0型恒星的确定，通过不同方法确定这些值的一致性进行了讨论。 这些恒星在HR图中的位置，考虑到HIPPARCOS数据进行了讨论。 从这种光谱调查中发现了大量具有相似光谱类型的双星。 显示英文摘要

摘要： The determination of the ``Fundamental Parameters'' T_eff and log g for a set of dwarf A0-type stars is discussed in terms of consistency when comparing these values determined through different methods. The position of these stars in the HR diagram are discussed, taking into account the HIPPARCOS data. A large number of binary stars with components of similar spectral types has been found from this spectroscopic survey.
