摘　　要：本文给出由Wackerling早型发射线星星表与IRAS点源表交叉认证得到的V-[25]≥8的早型发射线星星表。对它们空间分布的研究表明:这些星属于极端星族Ⅰ,从而为进一步研究主序前和主序后中等和大质量恒星的演化提供较为完备的观测对象。A catalogue of early-type emission-line stirs with large infrared excesses is presented by cross-identification between Wackerling's Catalogue and the IRAS Point Source Catalog with the criterion V-[25] 3≥8. A comparison is made between the well-studied objects and those for which nothing is known except for the PL emission behaviour. The Galactic distribution shows that most of them belong to extreme population I, and indicates the objects listed in this catalogue could mostly be stars of intermediate and high mass either in the pre- or post-main-sequence stage.
