标题： Spiral Galaxies and the Peculiar Velocity Field

摘要： 来自场旋涡星系 SFI 样本以及团簇旋涡星系 SCI 和 SC2 样本的特殊速度场的单极和偶极特征被展示出来。 单极成分在 7000 公里/秒范围内没有显示出 Zehavi 等人（1998）所提出的“哈勃泡”的证据；当地星系群的反射运动的偶极子在小于 6000 公里/秒时收敛于宇宙微波背景（CMB）偶极子，并且当参照由 SC2 团簇样本定义的参考框架时，在 20,000 公里/秒范围内仍与其一致。 显示英文摘要

摘要： Monopole and dipole signatures of the peculiar velocity field as derived from the SFI sample of field spirals and the SCI and SC2 samples of cluster spirals are presented. The monopole exhibits no evidence of a `Hubble bubble' within 7000 km/s as suggested by Zehavi et al. (1998); the dipole of the reflex motion of the Local Group converges to the CMB dipole within less than 6000 km/s, and remains consistent with it, when referred to the reference frame constituted by the SC2 cluster sample, which extends to 20,000 km/s.
