摘要
本文采用演化星族综合方法，讨论了在低红移因短时间星暴过程而变亮的矮星系族。指出，它们的存在能够与目前暗星系计数和红移巡天结果相容，作为一个附加的星系族，它们较易演化为低面光度的星系而在邻域中探测不到，因此是解释暗星系计数和红移巡天结果的适当候选天体，值得对它们作进一步的研究。
he dwarf population of starburst galaxies is analyzed by the Evolving Population Synthesis Method. The results show that the existence of an additional dwarf population can fit the observations of number counts and the redshift survey nicely.As an additional population these dwarf galaxies can evolve easily into low surface brightness galaxies and become undetectable in our local neighborhood. This population is a proper candidate for interpreting the observations of number counts and redshift surveys.
