摘　　要：本文给出使用上海天文台的40cm双筒折射望远镜拍摄的历元差平均18年的底片对测定的30颗天琴座RR型变量场星的自行，给出了它们的平均目视星等统一到Barnes的强度平均星等标度的强度平均星等。还列出了它们的金属丰度［Fc／H］。New proper motions of 30 RR Lyrae field stars are derived using the plate pairs with an average time interval of 18 yr with Zo-Se 40 cm refractor. In addition,intensity mean magnitudes of RR Lyrae stars using Barnes' method are derived,According to the Butler's relation between [Fe/H] and AS, metallicity [Fe/H] of RR Lytae stars is derived.
