摘要：
Based on the recent observations that one part of dwarf satellite galaxies fall into the gravitational well of the Galaxy while being disrupted by the tidal force. We study the distributions of disrupted dwarf galaxies through the links between minor merger processes in the history of the Galaxy and the observed distribution of metal-poor field halo stars. Our results show that the upper limit of 35% of the metal-poor halo field stars was established by merging of this kind of satellite galaxy with characteristic mass.
